Multiplex PCR amplification of four microsatellite markers and the SRY was
used to identify the sex of the ruminant in the study. Result indicates that
the SRY primers are highly specific and can be used as the main basis for sex-identification.
The markers of MCM158 and MAF45 are not suitable for sex identification because
their low specificity. If the PCR-products of MILVET09 and AE25 are positive
but the SRY is negative, then the individual is female. The gene type of MILVET09
and AE25 dose not affect the sex determination of the female. The gene type
of MCM158 and MAF45 dose not affect the result of sex-identification, but they
can further confirm the male identity. In conclusion, if the PCR-products of
SRY and four microsatellite markers are present simultaneously and the gene
type of MILVET09 and AE25 is homozygous, then the individual is determined to
be normal male, if the PCR-products of four microsatellite markers are present,
but the SRY gene is not, then the individual is female. And the gene type of
MILVET09 and AE25 does not affect the result of the sex-identification of tested
individuals.

The electrical fusion procedure used in Nuclear Transfer (NT) is one of the
critical factors affecting the efficiency of animal cloning. The objective of
this study was to compare the fusion competence of sika deer (Cervus nippon)
and bovine interspecies nuclear transfer (iSCNT) in different electrical fusion
parameters. The NT-embryos were obtained by transfer of the pedicle periosteum
cell of deer at the 4th passage into the enucleated metaphase II (M II) bovine
oocytes. As results shown, the percentage of couplets successfully fused at
2.4 kV cm-1 was the highest (57.2% vs 31.5, 41.0 and 45.7%, p<0.05).
The percentage of couplets successfully and reconstructed embryos cleaved were
the highest in 1 Direct Current (DC) pulse group but there were no significant
difference among all groups (p>0.05). The percentage of couplets successfully
fused in 10 μsec group (68.3%) was significantly higher than 40 μsec
group (37.5%, p<0.05). The percentage of reconstructed embryos cleaved was
64.7% at 2 h group, it was higher than 3 h group (26.0%, p<0.05). These results
suggested that electrical fusion procedure of 2.4 kV cm-1 EFS, 1
DC pulse, 10 μsec and 2 h after NT manipulation were feasible to iSCNT
of sika deer-bovine.

One of the important modifications that have been made in animal feeding is
the usage of the natural feeds and the feed supplements having any negative
impact on human health. Therefore, there has been an increase in the usage of
vegetable extracts together with the feeds in the broiler feeding. It is indicated
that the vegetable extracts ameliorates the feed consumption and the benefitting
from the feed and consequently have the positive impact on the live weight.
This study is carried out in order to ascertain the usage opportunities of the
artichoke extract (Cynara scolymus) that has positive productive effects
on broilers' feed and the vegetable extract named Bedqen 40 that includes choline
chlorite and their metabolic impacts on liver enzymes. The study was conducted
while using 100 Ross 308 hybrid chicks for 42 days as control and experimental
groups. In terms of the live weight at the end of the experiments, there is
a significant statistical difference between the groups (p = 0.0425). In respect
to the daily increase of live weight, the difference between the experimental
group and the control group is statistically negligible (p≥0.1104). There
is no difference in terms of the liver enzymes between the experimental group
and the control group both at the start and the end of the experiment (p≥0.1792).

Small (length <25 cm) indigenous fish species (SIS) play an important role in providing animal sources of protein in the poor rural houses of Bangladesh. They are also valuable sources of vitamin A, calcium and Iron. But since the green revolution started in Bangladesh their diversity has been decreased alarmingly. This investigation was carried out from December 2010 to November 2011 in the riversand beels of Karimganj Upazila, Bangladesh to assess the biodiversity status of SIS. The samples were collected from Balikholafish landing centre and thearea was visited at least once in a month. However, during the study period, only 30 species belonging to 7 orders and 15 families were identified where 19 species had normal abundance, 6 species moderate abundance and 5 species least abundance. The highest number (9) of species was recordedfrom the family Cyprinidae and Puntius sophore being the most dominant. Among the families, contribution of Cyprinidae was 30%, followed by Bagridae and Schilbeidae 10%, Channidae and Clupeidae 6.67% and rest of the each family was 3.33%. The species comprised 39% catfishes, 22% minnows, 17% barbs, 10% perch, 5% snakeheads, 2% gourami, and river shads, loaches, gar, glass fish, goby were 1% individually. The highest number of species (25) was found in October and the lowest (3) in February. The maximum yield of SIS was found in (Sep-Dec) period and the least availability of SIS found during (Jan-Apr). Among the fish species, 2 were considered as critically endangered (CR), 4 were endangered, 3 were vulnerable (VU) and 2 were Data Deficient (DD). From this repot, general people, researcher and policy makers would be able to know about the valuable SIS fishes of the study area, their present biodiversity status and their seasonal abundance. The information will be helpful for proper conservation and management of the SIS.

In this study, the structure and diversity of metazoan parasite community and their interactions with 696 Polydactylus sextarius have been studied for two consecutive years 2005-2006 and 2006-2007 from Visakhapatnam (17.67°’N and 83.32°’E), in the coastal zone of Bay of Bengal Andhra Pradesh. Of the 676 host species examined, 563 (83%) hosts were parasitized by at least one or more metazoan parasite species. A total of 5911 specimens were obtained representing 24 species comprising 2 monogenetic trematodes, 11 digenetic trematodes, 2 cestode larvae, 1 nematode, 4 Acanthocephalans, 3 copepods and 1 isopod. Endoparasites preponderate the majority of the components of the infracommunities analysed and represented 92.6% of the total parasites obtained. Larval cestodes (3515) and digeneans (1165) were the most prevalent in the parasite community of the host. Larval cestode, Scolex pleuronectis is the only secondary species while the remaining are satellite species being less in number. Impact of abiotic factors like temperature, water currents and biotic factors like feeding habit, diet, immunity, lifespan of host on parasitization; the relationship between host size and prevalence of infection were thoroughly investigated but the host sex was not taken into consideration due to protandrous nature of the host.

Effect of varying doses of Ovatide on the breeding performance of Clarias
gariepinus in Sokoto, North-western Nigeria was investigated. The females
weighed between 330 to 1078.50 g while the males weighed 317 to 542.40 g. Eight
gravid brood stocks were injected intramuscularly at different dose levels of
0.10 (treatment I), 0.15 (treatment II), 0.20 (treatment III) and 0.25 (treatment
IV) mL kg-1 b.wt. (Bw), at a water temperature of 30°C to assess
their breeding performance. The experiment was replicated in a completely randomized
design. The results showed that the size of eggs did not vary among the samples
based on all the treatments. The female of treatment IV had the highest spawning
fecundity (149,796), weight (228 g) and percentage of eggs stripped (21.14%).
Treatment III had the highest percentage of fertilized eggs (95.45%) which was
significantly (p<0.05) higher than in the other treatments. Treatment II
had the highest hatchability (65.28%), number of hatchlings (3,017) and total
weight of hatchlings (12.07 g). It was concluded that C. gariepinus
of about 400 g can successfully be induced to ovulate using 0.15 mL kg-1
b.wt. in Sokoto, Nigeria which was lower than the manufacturer’s
recommended dosage of 0.20 mL kg-1 b.wt.

A Total of one hundred and twenty broiler chickens at five weeks old were used
in an experiment to determine the responses of broiler chickens fed varying
levels (0,5,10, 15%) of dietary supplement of Telfaira occidentalis leaf
(pumpkin leaf) meal. The experiment was laid out in a completely randomized
design having four treatment groups and each treatment group was replicated
thrice with each replicate having a total of ten birds. Birds were fed and watered
ad libitum and the study lasted for 28 days. Results obtained showed
that daily body weight gain (g) were significantly (p<0.05) influenced by
10 and 15% experimental diets supplementation, having depressed body weight
gain compare with 5% level of supplementation and the control diets that were
similar in terms of body weight gain. Feed conversion ration were similar in
all the experimental groups, however, mortality was highest in the control group.
No significant differences (p>0.05) were observed for the groups with respect
to all the internal organs measured, with the exception of the small and large
intestine. The longest small intestine (which was thus significant, (p<0.05)
were recorded in the 10 and 15% group when compares with the control and 5%
treatment groups. Similarly, the large intestine was significantly (p<0.05)
longer in all the test diet supplemented with T. occidentalis leaf meal.
Haematological parameters assessed shows that significant (p<0.05) difference
existed in Parked Cell Volume (PCV%), mean corpsular haemoglobin (MCH p g-1)
and Mean Corpuscular Haemoglobin Concentration, (MCHC g dL-1). The
lowest values were observed in the control group which was significantly (p<0.05)
lower compare with those broiler chicken offered T. occidentalis leaf
meal. It was concluded that 5% level of dietary supplementation with sun dried
T. occidentalis leaf meal gave the best result.

Glycinin and β-conglycinin in soybeans can reduce the absorption of nutrients by young animals and result in watery diarrhea. In this study, self-prepared purified glycinin and β-conglycinin were applied to intestinal epithelial cells of primary cultured mice. The effects of purified glycinin and β-conglycinin (0.1, 5 and 10 mg mL-1) on Na+-K+-ATP enzyme, PEPT1 and DMT1 expression in mouse intestinal epithelial cells were studied. Glycinin and β-conglycinin could enhance epithelial cell Na+-K+-ATP enzyme activity but reduced the amount of PEPT1 and DMT1. The effect of β-conglycinin was more pronounced than that of glycinin.

This study aims to analyze the effect of biscuit bio-supplement on milk production
and quality at dairy goats farm . This research was conducted on June-October
2013 at different dairy goats farm in Bogor, Indonesia.. This research used
a factorial completely randomized design 2x2x6 with two treatments and six replications
which factor A was level of biscuit bio-supplement (T0 = 0% of biscuits bio-supplement
and T1 = 15% of biscuit bio-supplement). Factor B was different location of
dairy goat farms (Ciapus farm and Leuwiliang farm). The result indicated that
the treatments had significant effect (p<0.05) on milk production and calcium
content of milk. By feeding of 15% biscuit bio-supplement had milk production
673 mL head-1 day-1 at Ciapus farm while by feeding without
biscuit bio-supplement had milk production 671.99 mL head-1 day-1.
By feeding of 15% biscuit bio-supplement had milk production 539.75 mL haed-1
day-1 while by feeding without biscuit bio-supplement had milk production
318.28 mL head-1 day-1 at Leuwiliang farm. By feeding
biscuit bio-supplement did not significant effect (p>0.05) on fat, protein
and lactose of milk. By feeding 15% biscuit bio-supplement yield milk production
41.03% higher than conventional feed at the farm with using low protein of feed
while milk production approximetly only 0.15% higher than conventional feed
at the farm with using high protein of feed.

Vegetable waste is part from vegetables or vegetables that are not used or discarded in the market. The weakness of this vegetable waste is easy to decay, voluminous (bulky) and the availability was fluctuated, so the processing technology is needed to make this vegetable waste to be durable, easy to stored and easy to given to the animal. To solve this problem is making vegetable waste into wafer feed. The aim of this experiment was to determine the productivity of sheeps that were given by vegetable waste as wafer feed. Experimental design used randomized block design with 5 treatments and 3 replications. The treatments were wafer feed composition i.e R1 (100% of conventional feed), R2 (75% of conventional feed+25% of wafer feed), R3 (50% of conventional feed+50% of wafer feed), R4 (25% of conventional feed+75% of wafer feed), R5 (100% of wafer feed). Conventional feed were field grass and rice bran. The results of this research indicated that the treatments had not significant effect (p>0.05) on productivity of sheep. Sheep were fed by conventional fed had final body weight 27.07 kg, meanwhile sheep were fed 100% of wafer feed complete had 34 kg or 25.6% higher than conventional.

Brucellosis is an important zoonotic disease of animals and man causing different
reproductive problems like abortion, retention of placenta, repeat breeding,
still birth and many more. In this report, authors described an investigation
of brucellosis outbreak in an organized dairy farm, Agra, India causing abortions
and other reproductive disorders. Blood and environmental samples including
feed and water samples were collected in sterile containers. About 80% sera
samples collected from aborted animals and 60% sera samples from pregnant and
in-contact animals, maintained at the dairy farm contained antibodies against
Brucella spp., while all the bulls were found negative for presence of
anti-Brucella antibodies. Escherichia coli and Streptococcus
spp., isolates were recovered from water samples, while Staphylococcus,
Streptococcus spp. and Pseudomonas spp. could be isolated from feed
samples. In the present investigation, high prevalence of anti-Brucella
antibodies was found in sera samples of the animals, indicates that they all
had an exposure to Brucella spp. which might be the probable reason of
abortion storm. Thus, on the basis of our findings, it can be deduced that Brucella
might be associated with abortion in dairy animals even without apparent septicaemia
or any other manifestations. The presence of anti-Brucella antibodies
in sera samples of animals can be used as an indicator of infection in farm
animals.

The present study was aimed to report the diagnostic features of Pericardial
effusion (PE), observed in commonly employed cardiac diagnostic modalities viz.,
radiography, electrocardiography and echocardiography. A 9-year-old, female
Labrador Retriever dog (24 kg) was brought to the Referral Veterinary Polyclinic,
Indian Veterinary Research Institute-Izatnagar with the complaint of exercise
intolerance, listlessness, lethargy, generalized weakness and inappetence. Physical
examination revealed tachypnoea, distended abdomen and on auscultation muffled
heart sounds were observed. Based on physical examination findings, animal was
put on other cardiac diagnostic techniques to arrive at final diagnosis. Diagnostic
features characteristic to pericardial effusion, an abnormal accumulation of
fluid inside the pericardium, were observed. Globoid heart appearance and large
Vertebral Heart Score (VHS) was observed on lateral thoracic radiograph. Electrocardiography
(Lead II) revealed decreased R wave amplitude (decreased left ventricular contraction).
On echocardiographic examination an echo free space between epicardium and pericardium
was observed. All these findings were indicative of pericardial effusion, however,
without an exact aetiology. This article reports the successful diagnosis of
pericardial effusion in Labrador Retriever. However, to confirm the aetiology
other diagnostic tests like haematology, pericardial fluid analysis and histopathology
need to done.

Since nutrition demands a high percentage of production costs in shrimp culture,
the development of dietary strategies such as the inclusion of vegetable protein
sources, is a very important tool. Thus, digestibility of alternative feedstuffs
for evaluating its dietary potential as shrimp feed represents the first action.
The objective of study was to determine digestibility coefficients for protein,
energy, dry matter and amino acids of least snout bean and pigeon pea meals
in Pacific white shrimp juveniles. Thirteen isonitrogenous diets (34.8 to 35%
protein) were formulated and elaborated. One containing only fish meal as a
source of protein and the other replacing 10 and 18% of fish meal with the leguminous
seed meals Rynchosia minima and Cajanus cajan, previously subjected
to a thermal process for 0, 45 and 90 min. The shrimp were fed to satiation
four times daily for 25 day. The apparent digestibility coefficients were determined
using 0.5% Cr2O3. Feces were collected from three replicate
groups of shrimp. The results showed that shrimp fed with 10 and 18% Cajanus
cajan and Rynchosia minima replaced and subjected to a thermal process
of 45 min presented higher weight increase (p<0.05) and specific growth rate
compared with control diet group. L. vannamei had relatively high apparent
digestibility coefficients of crude protein (93.68 and 92.29%) and crude lipid
(96.87 and 97.55%) for CC10-45 and RM18-45 diets, respectively. Results suggest
that diets with both R. minima and C. cajan seed meals thermally
processed, can partially replace animal protein in shrimp diets at inclusion
levels of 10 and 18%, respectively.

Persicaria minor a widely used herb in South-east Asia, was reported to have high antioxidant contents and therefore can be potentially used to reverse the effects of lipid peroxidation caused by free radicals. In this study, the toxicity profile of this herb was evaluated based on haematological and biochemical analyses. In acute toxicity study, male Wistar rats were given a single dose of either 300, 1000 or 2000 mg kg-1 b.wt. of aqueous extract of Persicaria minor leaves via oral gavage. Rats were observed for mortality within 24 h. In subacute toxicity study, the rats were treated with the three different doses of the extract daily for fourteen days. At the end of the study period, blood was taken intraorbitally for haematology and biochemistry. Results showed that there were no signs of toxicity, behavioural changes or death observed in both studies. However, feeding of extract at the dose of 2000 mg kg-1 b.wt. for 14 days significantly reduced the haemoglobin, calcium and sodium while increasing the potassium levels. In conclusion, the extract from the leaves of Persicaria minor administered orally did not cause any acute or subacute toxicity to male rats, with the exception of the extremely large dose whereby it may lead to electrolyte imbalance, anaemia and hypocalcaemia.

The use of conventional feedstuff such as groundnut cake, fish meal, etc. as
supplement to low quality feed may not be cost effective in present day Nigeria
to intensify production, owing to their high cost, irregular supply. It’s
pertinent therefore to shift attention to the use of non-conventional protein
materials of farm waste origin such as poultry droppings. This study was therefore
initiated to determine the feed intake and nutrient digestibility of growing
Yankasa rams fed sorghum stover supplemented with graded levels of dried poultry
dropping based diets. Thirty growing Yankasa rams aged 9-12 months, weighing
11.5-15.5 kg were randomly divided into five groups (6 in each) and assigned
to five supplemental diets designated T1-T5. Fresh poultry
droppings were sun-dried for 3-5 days to minimize the level of microbes present.
Thereafter the product were milled and included in ram’s diet at 0, 20,
40, 60 and 80%. Animals were fed in the morning (supplementary) and evening
(basal diets). Salt-lick, water were also provided. Data were collected on feed
intake and nutrient digestibility coefficient. Results showed that rams fed
the control diet significantly (p<0.05) had lower feed intake as well as
apparent nutrient digestibility coefficient when compared with the rams fed
dried poultry droppings based diets. It was concluded that dried poultry droppings
inclusion up to 80% in the diet of the rams enhances feed intake and nutrient
digestibility and thus increases live weight gain. Therefore, sun-dried poultry
droppings can satisfactorily supplement sorghum Stover up to 80% inclusion level.

Since last decade, there is increasing reports of presence of extended spectrum β-lactamases producing bacteria especially from enterobacteriacae family. The presence of Extended spectrum β-lactamases (ESBL) producing E. coli causes a serious public health threat to human beings. The present study reports the isolation of extended spectrum β-lactamases producing α hemolytic Escherichia coli in Yellow-wattled Lapwing (Vanellus malabaricus) chicks. Escherichia coli organisms were isolated from three chicks suffering from unusual clinical signs and died before rehabilitation in the month of August 2010. Further assessment of isolates revealed their ability to bind with Congo red dye on Tryptic soy agar media and α hemolytic nature on 5% chicken blood agar. As usual when drug sensitivity was performed it revealed their multi drug resistance pattern which on further examination with double disk method showed them to be extended spectrum β-lactamases producing Escherichia coli. The presence of enterohemorrhagic extended spectrum β-lactamases producing Escherichia coli in Yellow-wattled Lapwing is a matter of concern as it may be due to the transmission from human being as these Lapwings are residing in the close vicinity of university premises. Moreover, their nesting areas are also very near to the place where carcasses of dead animals were disposed off during that period of time. To the best or our knowledge, this appears to be the first report of pathogenic E. coli identified in Yellow-wattled Lapwing, implicating Yellow-wattled Lapwings as a new potential reservoir of these zoonotic pathogens.

The present study was undertaken to evaluate the hepato-protective effect of
crude flavonoid fraction of aerial parts of Lippia nodiflora in ethanol
induced oxidative stress in liver using experimental animal models. Ethanol-fed
(5 g kg-1 day-1) male rats were treated by crude flavonoid
fraction (25, 50 mg kg-1) for 21 days. The liver damage was indicated
by the significant increase in serum AST, ALT, ALP, LDH, total bilirubin, urea
and decrease in total protein and triglyceride (TG). Lipid peroxidation markers
like Thiobarbituric Acid Reactive Substances (TBARS) and antioxidant enzymes
namely superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH),
Glutathione Reductase (GR) and Glutathione-S-transferase (GST) activities were
also measured. The crude flavonoid fraction showed significant (p<0.05) protective
effect by decreasing the elevated liver marker enzymes, total bilirubin, lipid
peroxidation marker and ameliorated the diminished serum total protein as well
as antioxidant levels in a dose dependent manner. The protective effect of the
crude flavonoid fraction was observed at both concentrations and was compared
to that of the standard used. Hence, our results highlights the ability of crude
flavonoid fraction of Lippia nodiflora to ameliorate oxidative damage
in the liver and the observed effects are associated with its antioxidant activities.

Brucellosis is an infectious disease characterized by abortions in females
and epididymitis and orchitis in males. There is paucity of information on the
occurrence of brucellosis among small ruminants in Yabello district. Therefore,
this study was designed with the aims to determine the prevalence and assess
risk factors associated with the occurrence of brucellosis among small ruminants
in the district. Seroprevalence study of small ruminant brucellosis in Yabello
district was conducted from November 2009 to April 2010. Sera from 384 sheep
and goat were tested by Rose Bengal Plate Test. Of 384 sera examined 9 (2.34%)
were positive to RBPT. The sera screened positive by RBPT were retested using
complement fixation test and among 9 sera samples tested 6 (1.56%) were positive
for Brucella antibodies. The prevalence of brucellosis in this study
among sheep and goats was found to be 1.17 and 1.88%, respectively. Small ruminant
brucellosis among male and female animals was known to be 0.68 and 2.10%, respectively.
Prevalence of small ruminant brucellosis in young animals was 0% while that
of adult was 2.30%. Statistical analysis of the data showed that there was no
significant difference in seroprevalence to Brucella antibodies and species,
sex and age of the animals examined (p>0.05). The occurrence of brucellosis
among small ruminants in Yabello district might pose productivity and reproductivity
problem and will be a public health risk. Therefore, best control and prevention
methods brucellosis among small ruminants need to be implemented.

The objective of this study was to estimate the heritability and variance component of Body Condition Score (BCS) of adapted Holstein Friesian in the Kingdom of Saudi Arabia (KSA). The analysis of test day records for dairy cattle and covariance functions of random regression analysis allowed a continuous change of variances and co-variances of BCS on different lactation parts, cow ages and levels of daily milk production. Quadratic Legendre polynomials were used to estimate (co)variances of random effects. A model for analyzing test day records containing both the fixed and random regression coefficients was applied for genetic evaluation of first three lactations. Data was 45,349 BCS observations from calvings between 1989 and 1998 from four different dairy herds in KSA. Each evaluated animal received at least two measurements for BCS representing the random regression coefficients. Three genetic measures of BCS such as cow age, days in milk and the levels of daily milk production were compared. Overall means of BCS across early, mid and late part of production live were 2.8±0.10, 3.3±0.05 and 2.9±0.04, respectively. Based on the random regression solutions, the estimated heritability ranged from 0.19-0.53 for various parts of lactation and 0.02-0.48 across different cow age for BCS. The highest estimate of heritability of BCS based on random regression function of daily milk yield was 0.37 at 10 kg day-1. The corresponding lowest estimate of heritability was 0.26 at 35 kg day-1. The study showed a potential of using random regressions for estimating heritability in adapted animals under different environments.

The lizard, Acanthodactylus boskianus has recently been reported from the west of Iran. The purpose of this study was to examine the morphology and histological structure of excretory system in this species. To perform this task, a number of 12 lizards (male and female) were collected from their natural habitat and transferred to the laboratory where their kidneys and excretory ducts were dissected out. The dissected samples were then processed to be prepared for histological examinations. Microscopical observations showed that in this taxon there is no evident boundary between the cortical and medullar regions of kidneys. It also demonstrated that each kidney consists of very few nephrons which do not show any loop of Henle. Each nephron is composed of a glomerulus surrounded by a doubled-walled Bowman’s capsule, the other segments are proximal tubule, distal tubule, connecting tubule and collecting duct. The epithelial tissues lining the lumen of these segments were simple cubiodal cells, cubiodal cells, columnar and tall columnar cells, respectively. A ureter is located on the ventral surface of each kidney. The ureters open into the urodaeal cavity of the cloaca with a common duct or tube. In general, this lizard as other reptiles live in such areas display few glumeruli in the kidneys and highly likely produce the urine that is hyposmotic with blood.

The performance of grazing West African Dwarf (WAD) goats on Moringa Multi
Nutrient Block (MMNB) supplementation was assessed relative to cassava peels
(CPL) and corn starch residues (CSR), using a complete randomized design with
four replicates per treatment. Performance indices were supplement intake and
experimental animals’ weight
and haematological changes. Statistical (p<0.05) differences were observed
in supplement intakes, which were 11.08, 23.61 and 34.53 g-1 kg0.75
for MMNB, CPL and CSR respectively. MMNB however had higher nutrient contents.
Weight changes were positive across treatments. Mean weight gain for animals
on MMNB supplementation (38.10 g day-1) was however significantly
(p<0.05) higher than those of the animals on the reference supplements, which
showed no statistical (p>0.05) difference. Only MMNB supplementation resulted
in a significant (p<0.05) increase in Packed Cell Volume (PCV) at the end
of the study although all values fell within the range considered normal for
clinically-healthy WAD goats. Each of the three supplements resulted in significant
(p<0.05) increases in Haemoglobin (Hb) and Red Blood Cell (RBC) counts, although
the magnitudes of the increases were most pronounced with MMNB. Animals on CSR
maintained relatively comparable levels of WBC at both the commencement and
end of the study. However, CPL supplementation resulted in higher (p<0.05)
WBC values at the end of the study whereas MMNB supplementation resulted in
corresponding lower (p<0.05) values. Hence, adoption of the MMNB feeding
technology by small ruminant keepers could be a panacea to the nutritional and
health hardships faced by the animals during the usually long dry season.

The semi-ranched Bohor reedbuck Redunca redunca (Pallas 1767) population was studied in Jimma Airport Compound (JAC), southwestern Ethiopia, to assess the ecology, activity patterns, threats and the potential hazards they pose on the aviation services of the area. Total count method was employed to determine the population size. Scan sampling, from 2-10 min interval was used to record the diurnal and nocturnal activities. The swampy grassland habitat of JAC harboured over 220 individual Bohor reedbucks of all age categories. The sex ratio of the reedbuck population was 1:1, however, biased towards adult individuals (63%). Bohor reedbucks of the JAC are exclusively diurnal. They usually form unstable groups of four different herds comprising 3-11 individuals. Over 85% of the reedbuck population passes the night within 200 m radius of the main terminal. They cross the runway at any hour of the day but most with three peaks (early morning, mid-day and early evening). Pregnant, lambing and estrous female reedbucks were commonly observed during both seasons. They employ cryptic behaviour, lying position, alarming whistles and night time refugia selection as an anti-predatory behavior. Predation pressure, habitat confinement, poaching, habitat fragmentation and excessive human activities were considered threats to these animals. By connecting these populations with the ones found nearby in the Kitto-Furdisa University campus, establishing Bohor reedbuck sanctuary is recommended to safeguard the survival of this conservation dependent endemic sub-species.

The use of frozen semen in rabbits is greatly limited due to its low fertility
rates. The current study aimed to evaluate the effect of gelatin addition to
semen extender on motility, livability, abnormality and acrosome integrity of
rabbit spermatozoa during freezing process and on fertility after Artificial
Insemination (AI). Pooled semen collected from bucks (n = 15) belonging to a
line selected by Animal Production Research Institute, Egypt (APRI). Semen was
processed in tris-buffer extender with gelatin addition at levels of 0, 1, 2
and 3% (g/100 mL extender) at a rate of 1:5, and frozen in liquid nitrogen.
Results showed that when compared with control semen, 2% gelatin addition had
positive (p<0.05) effect on percentages of motility, livability, abnormality
and intact acrosome o f spermatozoa in post-diluted (73 vs. 65.5%; 73.9 vs.
66.9%; 12.2 vs. 15% and 81 vs. 70%), post-equilibrated (71 vs. 60%; 71.7 vs.
60.4%; 12.6 vs. 15.1% and 80.2 vs. 67.5%) and post-thawed (54.5 vs. 31%; 54.6
vs. 31.4%; 18 vs. 21.4% and 71.4 vs. 56%) semen, respectively. Semen with 2%
gelatin yielded the highest (p<0.05) kindling rate (75%) and litter size
(6.93) as compared to control semen (65% and 6.08/doe), respectively. Adding
2% gelatin to tris-buffer extender of APRI rabbit semen enhanced freezing ability,
efficiency and fertility of spermatozoa in thawed semen.

Ethnoveterinary practices hold a promising scientific resource and can have
far-reaching implications on economic development and enhancement of veterinary
health care system. The present study was undertaken to evaluate the oxytocic/tocolytic
activities of Cimicifuga racemosa (C. racemosa) roots extracts
on isolated uterine strips of pregnant buffalo. Hot methanolic extraction of
authenticated roots of C. racemosa was done using soxhlet extractor.
Hot methanolic extract of C. racemosa roots was found to exert a myometrial
relaxant effect which was potentiated after inhibition of excitatory muscarinic,
alpha and beta adrenergic, H1-histaminergic and 5-HT receptors. Further
studies are required on mechanistic aspects of tocolytic effect of C. racemosa
particularly to elucidate the involvement of Ca2+ and K+
channels, NO and other signaling mechanisms including second messengers.

Contagious caprine pleuropneumonia caused by Mycoplasma capricolum subspecies capripneumoniae is a highly contagious and serious respiratory disease of domestic goats, characterized by coughing, severe respiratory distress and high mortality rates. There is dearth of well documented information on the occurrence of contagious caprine pleuropneumonia among goats in Jijiga zone, Ethiopia. Therefore, this study was designed with the aims to determine the seroprevalence of caprine pleuropneumonia in the selected districts of Jijiga zone and to assess potential risk factors on the occurrence of the disease. Cross-sectional study design was conducted from November 2011 to March 2012 among selected districts of Jijiga zone namely Jijiga, Kebri Beyah and Tuli Guled districts. A total of 334 goat sera were examined for the presence of specific antibodies against Mycoplasma capricolum subspecies capripneumoniae using complement fixation test. Proportions and chi square test statistics were used to analyze the data. District, sex and age of the goats were considered to be the major risk factors for the occurrence of contagious caprine pleuropneumonia. The overall seroprevalence of contagious caprine pleuropneumonia in Jijiga zone was proved to be 32.63%. The seroprevalence of contagious caprine pleuropneumonia at District level was confirmed to be 34, 33.64 and 28.38% in Jijiga, Kebri Beyah and Tuli Guled districts, respectively. The result indicated that there was no statistical significant difference (p>0.05) on seropositivity among the three districts and between the two sex of goats examined in this research. Age was found to be significantly associated (p<0.05) with the prevalence of contagious caprine pleuropneumonia in goats. In conclusion the present study indicated that the overall prevalence of contagious caprine pleuropneumonia in Jijiga zone was high and underlines the importance of further epidemiological study of the disease and its associated risk factors and implementation of appropriate preventive and control measures. Besides to this finding suggests the need to implement strict awareness creation among goat owners on vaccination of their animals in order to decrease the prevalence of contagious caprine pleuropneumonia in Jijiga, Kebri Beyah and Tuli Guled districts.

Recently, there are wide potential application of biotechnology in the field of animal production to increase the productivity of animals through better plane of nutrition, better production potential and improved health conditions. Nutrients like protein, aminoacids and fats can be produced or protected according the need at different physiological states of the animals. Enzymes can be used to improve the availability of nutrients from feed and to reduce the wastage of the feed and fodder. Prebiotics and probiotics or immune supplements can be useful to inhibit enteric pathogenic bacteria. Along with these use of plant biotechnology to produce feed and fodder with good nutritive values can be done with ease. Addition of vaccines or antibodies in feeds can be used to protect the animals from the disease. Genetic manipulation of rumen microbes can be done to improve the animal health. However, it is very difficult to accept the role of biotechnology in animal nutrition and it mainly depends on social and cultural aspects and economic importance to consumers and society.

This study was conducted to identify White Spot Syndrome Virus (WSSV) and Infections Hypodermal and Hematopoietic Necrosis Virus (IHHNV) by using clinical and histopathological sings of cultured shrimp, Litopenaeus vannamei in Bushehr farms, from December 2009 to April 2010. Samples were collected from Bushehr shrimp farms and hatcheries. Based on histopathological and gross signs, two viral diseases, WSSV and IHHNV have been detected. The gross signs of WSSV in the moribund samples showed reduced feeding, lethargy, difference in size, reddish coloration of appendages and white plaque on the carapace, while the gross sign of IHHNV exhibited abdominal dorsal changes of the muscles, opaque or milky spot on the cuticles, rostrum deformity syndrome and abdominal segmental abnormalities. The histopathological observations of WSSV showed basophilic Cowdry type A inclusion bodies in all tissues such as gills, haematopoietic tissue, cuticle epithelium, lymphoid organ and connective tissue. However, histologically, the hepatopancreas tissue showed vacuolization of B cells, without inclusion bodies. The histopathological signs observed such as hypertrophy, cellular degeneration and eosinophilic Cowdry type A inclusion bodies in the cells nucleus hepatopancreas, gills, haematopoietic, cuticle epithelium, digestive epithelium, lymphoid organ and connective tissue. Also, histopathological change of the striated muscles of the affected abdominal segmental abnormality showed severe Zenker's necrosis.
