Data relating to 130 sows, 19 boars from 400 farrrowings spread over a period from 1984 to 1992 were utilized to study genetic and non-genetic effects in variation of litter size and weight at birth and at weaning. The overall mean litter size at birth (LSB)was 6.83 ± 0.13 piglets. The effects of period, season of farrowings and inbreeding on litter size at birth were not significant (P>0.05).The overall least squares mean of litter size at weaning(LWW) was 4.83 ± 0.12 and was significantly (Pd”0.05) affected by in breeding. Litter weight at birth (LWB) had a least square mean of 7.81 ± .16 kg and it was significantly (Pd”0.05) affected by period of farrowing. The mean LWB of non-inbred sows was 8.22 ± 0.19kg and that of inbred sows was7.41 ± 0.29 kg. The overall least squares mean for litter weight at weaning (LWW) was 39.36 ± 1.25 kg and inbreeding of sow exerted significant effect on LWW. The LWB and LWW were significantly affected by period of farrowing. The litter size at birth and at weaning and litter weight at birth and at weaning was not significantly affected by season of birth. The heritability estimates of litter size at birth and litter size at weaning were 0.096 ± 0.09 and 0.816 ± 0.27 respectively. The corresponding heritability values for LWB and LWW were 0.41 ± 0.18 and 0.53 ± 0.21 respectively. 

An experiment was conducted on 18 un-castrated crossbred (Beetal x Assam local) kids of 3-4 months of age to study the effect of shed roof colour and bedding materials on growth performance during winter season. Three groups of six kids in each were housed in three sheds: T1 (shed roof painted with black colour on top and white colour inside and paddy straw bedding material mixed with hydrated lime, T2 (shed roof painted with black colour on top only and paddy straw without any treatment and T3 (shed roof without any colour and bedding material). The shed T1 and T2 were covered with hessian clothes except the ventilators. The roof shed painted with black colour on top and white colour inside along with hydrated lime mixed bedding material (T1) might have provided better and comfortable micro environment both in terms of optimum temperature and hygienic condition that resulted in significantly (P<0.010) higher body weight in kids (9.59 ± 0.20 kg) than T2 (9.15 ± 0.17 kg) and T3 (8.96 ± 0.0.33kg) respectively. 

Laminitis is inflammation of sensitive laminae of the foot in horses and donkey. The front hooves are most commonly affected than hind feet. Laminitis can be mechanical or systematic, acute or chronic, unilateral or bilateral or sometimes all four feet were affectedDonkeys appear to be particularly susceptible to laminitis may be due to live in the desert and dry area so their ‘good bacteria’ are even more sensitive to carbohydrate overload than those of ponies and horses there certainly is no lush grass in the desert and dry area. A two year old male donkey walking very tenderly and repeated raising of left hind leg. The affected hind leg foot was cleaned with 1% Kmno4 solution for avoiding secondary bacterial infection Inj. Meloxicam 35mg I/M, in, inj. Strepto penicillin 500mg I/M were given. The affected left hind leg was exposed to infra red light for 5 minutes and hot fomentation was given with hot salt and hot rice bran mixture. Iodine ointment was applied over the swollen coronary band area of left foot.

In animal breeding, genetic disorders are one of the most important issues for breeders. The present study was carried out to genotype HF crossbred cattle for FXI deficiency and CVM using PCR and PCR-RFLP using 50 blood samples. Amplicons of 244 bp for FXI gene and the 287 bp for SLC35A3 gene were successfully amplified. Analysis of amplicons of FXI gene revealed single 244 bp fragment which indicates absence of mutant allele. The amplicons of 287 bp of SLC35A3 gene was digested with Pst I RE which revealed two fragments of size 264 bp and 23 bp  for normal animals. In the present study, out of fifty HF crossbred animals screened neither carrier nor affected animals were found for FXID and CVM.

The research was carried out to study the effects of dietary supplementation of Tulasi (Ocimum sanctum) and selenium on ALT and AST enzyme levels in broiler chicken. A total of forty-two broiler chicks of day old divided into six groups of seven each were used for this study. Ocimum sanctum leaf powder (0.25% and 0.5%), organic selenium (0.3 ppm) and their combinations were added to the basal diet. Body weight and feed consumption were recorded at weekly intervals. Blood samples were taken at the end of 6th week for enzymological assay from each treatment. The enzymes assayed were alanine transaminase (ALT) and aspartate transaminase (AST). Dietary supplementation of Ocimum sanctum leaf powder at 0.25%, 0.5% levels and its combination (0.5% level) with selenium (0.3 ppm) reduced the levels of ALT and AST significantly (P<0.05). It was concluded that Tulasi (Ocimum sanctum) has hepato-protective properties.

Odontotermes formosanus termites are recognized as one of the major ecosystem engineers in tropical soils. This termite depends on intestinal microorganisms for cellulose digestion. Nine bacterial isolates from termite gut were identified using sugar fermentation and biochemical tests and confirmed by 16S rRNA gene sequencing. The aerobes isolated from the termite gut were Bacillus sp., Citrobacter freundii and Pseudomonas aeruginosa. The facultative anaerobes isolated were Salmonella entrica, Enterococcus casseliflavus, Staphylococcus gallinarum and Serratia marcescens. DNA from these bacterial cultures was extracted for molecular identification by 16S rRNA gene amplification. The cellulolytic activities of these bacteria were assessed by congo red assay. This study revealed the presence of cellulolytic aerobic and facultative anaerobic bacteria in the gut of termite Odontotermes formosanus which could be manipulated for their cellulose digestion in rumen. 

A 3 months old goat kid presented to Veterinary Dispensary, Chetiyur, Salem district Tamil Nadu   with case history of ring like patches on the body complete alopecia, frequent itching with thick and scaly skin . Dermatophytes are cited among the most frequent causes of dermatological problems in domestic animals. The superficial mycoses caused by dermatophytes are called dermatophytosis- Trichophyton are usually the cause of dermatophytosis in domestic animals. Trichophyton verrucosum is the major fungal agent encountered in case of goats. Direct microscopic examination of skin scrapping with 20% KOH revealed long chains densely packed chlamydiospore found with swollen hyphae. The skin scrapping materials cultured in thiamine inositol nutrient supplement selective culture medium. Long chains of densely compacted chlamydospores present in lactophenol cotton blue staining. The goat kid recovered within a week by external antifungal and systemic antibiotic and nutritional therapy with good hygienic management.

A two year old male cat was presented to the Emergency and Critical Care Unit with a history of inappetence after paracetamol 300 mg (Half tablet of 600 mg) administration overnight. On clinical examination the cat had a mild elevation of vital signs. Based on history and clinical signs the case was diagnosed as paracetamol poisoning and treated with activated charcoal a total dose of 3 g)orally and N-acetyl cysteine intravenously at 140 mg/kg along with Ringer’s lactate, 10 ml/kg b.wt. The owner was advised to administer Nacetyl cysteine at 70 mg/kg orally for every 6 hours for five times. After treatment the cat was recovered successfully.

Commercial cocktail enzymes were collected from the market and evaluated for enzyme activity. Among the enzyme preparations which is having more enzyme activity was selected for invitro evaluation by using de oiled rice bran as substrate. The results of the present study indicated that a significant (P < 0.05) and linear increase in the release of glucose and reducing sugars with the increase in the level of enzyme mixtures from 0 to 7.5 mg / 10 g of DORB.

An experiment was conducted to study the influence of sprouted green gram, selenium and vitamin E and their combinations on reproductive performance like semen quality and fertility for a period of five weeks with forty two adult White Leghorn cocks and seventy White Leghorn hens which were divided into seven treatment groups containing six cocks and ten hens for each treatment. The treatment groups consisted of control (T1), sprouted grains 50g/kg (T2), selenium 0.5mg/kg (T3), vitamin E 500mg/kg (T4), sprouted grains 50g/kg + selenium 0.5mg/kg (T5), sprouted grains 50g/kg + vitamin E 500mg/kg (T6) and sprouted grains 50g/kg + selenium 0.5mg/kg + vitamin E 500mg/kg (T7). Significant (P<0.05) difference was observed between treatment groups. The overall sperm motility of treatment and control groups did not differ significantly. The sperm concentration was significantly (P<0.05) higher in all treatment groups compared to control.  Inclusion of sprouted green gram, selenium and vitamin E had significantly reduced the overall dead (P<0.01) and abnormal (P<0.05) sperms when compared to the control group.
