Aim: The present study was conducted to find out the incidence and to evaluate the effectiveness of medial patellar desmotomy (MPD) in lateral recumbency in bovines.
Material and Methods: One hundred and fifteen clinical cases of upward fixation of the patella in cattle and buffaloes were treated by closed MPD in lateral recumbency. Probable etiologies, symptoms and site of surgery including disease occurrence with respect to species, sex and season were also recorded.
Results: In the present study, the highest incidence was reported in bullocks. A high success rate was obtained with the closed method in lateral recumbency.
Conclusion: Based on the findings of this study, it can be concluded that the bullocks were more prone to upward fixation of patella and symptoms were exaggerated in winter season. Closed method of MPD was more suited in both cattle and buffaloes.
Keywords: bovines, desmotomy, incidence, recumbency.

Aim: The aim was to assess the seroprevalence of B. abortus and Leptospira hardjo in the cattle population of Bihar, this work was carried out.
Materials and Methods: Randomly selected 450 cattle from nine districts of Bihar were serologically screened for antibodies against L. hardjo and B. abortus. DAS-ELISA for leptospira and AB-ELISA for brucella were carried out. Based on the results prevalence in each district and the state are reported herewith.
Results: In this study, it was found that the seroprevalence of L. hardjo was 9.11% and that of B. abortus was 12.2% in Bihar. Indigenous cattle were found to be less susceptible to leptospirosis and brucellosis even though they accounted for 83.11% of the study population.
Conclusion: Although there was no acute disease, antibodies detected against L. hardjo and B. abortus in the cattle population indicated the presence of chronic and subclinical infection, which could challenge the fertility of the animals.
Keywords: brucellosis, cattle, infertility, leptospirosis, seroprevalence.

   doi: 10.14202/vetworld.2015.213-216





Aim: The present study was carried out to evaluate the effect of supplementation of β-mercaptoethanol (β-ME) on in vitro maturation rate and glutathione (GSH) level of buffalo oocytes.
Materials and Methods: Oocytes were recovered from buffalo’s ovaries collected from government approved slaughter house (near Kamela darwaza, Surat) of Surat Municipal Corporation. The obtained oocytes were in vitro matured in maturation media supplemented with 0 μM (117 oocytes), 100 μM (46 oocytes) and 200 μM (42 oocytes) concentration of β-ME. After 24 h of incubation, maturation rate of oocytes and intra-cellular GSH level were determined.
Results: The results showed that the presence of β-ME did not influence (p>0.05) the oocyte maturation rate. However, GSH level increased significantly (p<0.05) in matured oocytes when supplemented with 100 μM and 200 μM β-ME (6.19±0.10 and 6.37±0.20 pmol/oocyte) as compared to control media (4.68±0.26 pmol/oocyte).
Conclusion: It was concluded that β-ME may have a potential to increase the meiotic maturation of in vitro cultured oocytes and protect it from oxidative damage.
Keywords: buffalo oocytes, in vitro maturation, β-mercaptoethanol, glutathione.

Veterinary World, 8(2): 208-212



   doi: 10.14202/vetworld.2015.208-212




Aim: The present study was conducted to evaluate the equine palmar tendon by ultrasonography (USG) in standing the position.
Materials and Methods: USG of palmar tendons was performed in 40 adult horses using linear transducer having frequency of 10-18 MHz (e-soate, My Lab FIVE) and L52 linear array transducer (Titan, SonoSite) with frequencies ranging from 8 to 10 MHz. Palmar tendon was divided into 7 levels from distal to accessory carpal bone up to ergot in transverse scanning and 3 levels in longitudinal scanning.
Results: The USG evaluation was very useful for diagnosis of affections of the conditions such as chronic bowed tendon, suspensory ligament desmitis, carpal sheath tenosynovitis and digital sheath effusions. The mean cross-sectional area (cm2) of affected tendons was significantly increased in affected than normal tendons. The echogenicity was also found reduced in affected tendons and ligaments along with disorganization of fiber alignment depending on the severity of lesion and injury.
Conclusion: USG proved ideal diagnostic tool for diagnosis and post-treatment healing assessment of tendon injuries in horses.

   doi: 10.14202/vetworld.2015.203-207


Aim: The present study was conducted to examine the rumen modulatory effect of thyme, clove and peppermint oils on rumen fermentation pattern in vitro using roughage based diet.
Materials and Methods: Thyme, clove and peppermint oils were tested at concentration of 0, 30, 300 and 600 mg/l (ppm) of total culture fluid using in vitro gas production technique in wheat straw based diet (concentrate: Wheat straw 50:50). Different in vitroparameters e.g., total gas production, methane production, nutrient degradability, volatile fatty acid (VFA) production and ammonia nitrogen concentration were studied using buffalo rumen liquor.
Results: Thyme oil at higher dose level (600 ppm) reduced (p<0.05) total gas production, feed degradability and ammonia nitrogen (NH3-N) concentration whereas total VFA concentration was significantly lower (p>0.05) in 300 and 600 ppm dose levels. 600 ppm dose level of clove oil reduced (p<0.05) total gas production, feed degradability, total VFA and acetate to propionate ratio. Methane production was significantly reduced (p<0.05) in 300 and 600 ppm dose levels of clove and peppermint oil.
Conclusion: Right combination of these essential oils may prove to enhance performance of animals by reducing methane production and inhibiting protein degradation in rumen.
Keywords: ammonia nitrogen, essential oil, rumen fermentation, methane, wheat straw.

Aim: The present experiment was conducted to study the effect of post hatch dietary fat supplementation on performance of broiler chicken.
Materials and Methods: A total of 120 day-old Ven Cobb broiler chicks were randomly assigned to 4 treatment groups of 30 chicks in each (three replicates of 10 birds/treatment). The trial lasted for 35 days. The experimental design was a completely randomized design. Four types of diet were formulated for 1st week: T1, T2, T3 and T4 contained control diet with no added fat, 2.5, 5 and 7.5% fat, respectively. After 1st week post-hatch period chicks were fed ad libitum with the normal basal diet as per Bureau of Indian Standard recommendations till completion of the experiment (8-35 days).
Results: Significantly higher (p<0.05) body weight and improved feed conversion ratio (FCR) was recorded in birds fed 5% dietary fat at the end of the experiment whereas, feed intake was not significantly affected. Significantly (p<0.05) higher dressed weight was observed due to 5% fat supplementation than other groups whereas, it was not significant for other carcass cuts. No significant differences were observed in moisture, protein and lipid content of breast and thigh muscle of broiler due to supplemented fat whereas, 2.5% dietary fat significantly (p<0.05) increase the serum HI titer on day 28th. In biochemical profile, higher serum albumin (g/dl) was recorded due to 5% fat supplementation whereas other biochemical components did not show any significance difference among treatments.
Conclusion: It may be concluded that supplementation of fat in broilers diet improves the overall FCR, dressing percentage and gain more body weight.

Aim: The objective of this study was to investigate the chromosomal profile of indigenous pigs by computing morphometric measurements.
Materials and Methods: A cytogenetic study was carried out in 60 indigenous pigs to analyze the chromosomal profile by employing the short term peripheral blood lymphocyte culture technique.
Results: The modal chromosome number (2n) in indigenous pigs was found to be 38 and a fundamental number of 64 as in the exotic. First chromosome was the longest pair, and thirteenth pair was the second largest while Y-chromosome was the smallest in the karyotype of the pig. The mean relative length, arm ratio, centromeric indices and morphological indices of chromosomes varied from 1.99±0.01 to 11.23±0.09, 1.04±0.05 to 2.95±0.02, 0.51±0.14 to 0.75±0.09 and 2.08±0.07 to 8.08±0.15%, respectively in indigenous pigs. Sex had no significant effect (p>0.05) on all the morphometric measurements studied.
Conclusion: The present study revealed that among autosomes first five pairs were sub metacentric, next two pairs were sub telocentric (6-7), subsequent five pairs were metacentric (8-12) and remaining six pairs were telocentric (13-18), while both allosomes were metacentric. The chromosomal number, morphology and various morphometric measurements of the chromosomes of the indigenous pigs were almost similar to those established breeds reported in the literature.
