The present study was conducted to study the vitreous humor between eye differences and baseline values of potassium, sodium, calcium and glucose immediately after death in dogs. Eight canine carcasses brought for necropsy formed the material for collection of vitreous humour in the present study. The information regarding time of death was gathered from dog owners, clinicians and clinical records. Eyes were enucleated as soon as possible after receiving carcass for postmortem. Sampling of vitreous humor was done using 16 gauge needle and 20 ml syringe. The needle was inserted at the lateral angle of eyeball so that the tip of needle was placed at the center of the eyeball. About 50 µL vitreous humour was gently aspirated from each eye and transferred to eppendorf tubes. Sampling of vitreous humour was done within 1-4 hours after death. The aspirated vitreous humour samples were centrifuged at 13,000 rpm for 15 min at 50C temperature and the supernatant was used for analysis. The average vitreous humour concentrations of potassium, sodium, calcium and glucose estimated within 1-4 hours after death were 8.18±0.31 mEq/L, 152.55±4.46 mEq/L, 9.52  ±0.20 mg/dL and 21.70±4.50 mg/dL respectively. The results of this study indicated that there were no significant differences between left and right eye  for all of the vitreous biochemical constituents that were studied in present study (estimated within 1-4 hours after death).

A study was conducted to analyse the migratory sheep production system in southern agro-climatic zone of Tamil Nadu. Reproductive performance of the rams and ewes was recorded through the questionnaire both in migratory and non-migratory flocks. Mean lambing percentage, twinning percentage, livability at birth percentage, age at first mating (months) in ewes, age at first mating (months) in rams, age at first lambing (months) and weaning percentage in migratory and non-migratory flocks were 93.56 and 91.50; 1.87 and 1.52; 98.32 and 98.73; 12.34 and 13.22; 19.64 and 21.44; 18.54 and 19.68; 85.98 and 87.15, respectively. The weaning period for ram and ewe lambs were 2.94+0.96 and 5.03+0.13 in migratory flocks and 4.82+0.13 and 6.06+0.17 in non-migratory flocks, respectively. Reproductive performance of sheep in migratory flocks was significantly better than nonmigratory flocks. The months of October,  November and December were main lambing season and the months of April and May were second lambing season.

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.

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. 

This experiment was carried out to study the effect of frozen storage on the physico-chemical quality of quail breast meat. Six weeks old broiler quails were collected, slaughtered, dressed hygienically. Quail breast meat samples were collected from dressed carcass which was packed in low density polyethylene pouches taking optimum care to avoid contamination and stored at -18 ± 20 C for 60 days.  Fresh as well as frozen quail breast meat samples were evaluated for physico-chemical and histological changes. Frozen meat samples were analyzed after thawing at 4 ± 10 C for 12 hrs at an interval of 15, 30, 45 and 60 days. It was observed that with advancement of the frozen storage period pH, TBA value, tyrosine value and drip loss increased, whereas moisture, protein, fat and ERV content of quail meat decreased. Pronounced structural changes reported at later part of storage in histological study due to formation of ice crystals in the muscles. It shows that quail meat can be safely stored for 60 days in frozen state without any marked changes.

A study was undertaken to assess the effect of betel leaves (Piper betel Linn) extract on the physico-chemical, sensory and antioxidant properties of khoa made from cow’s milk and stored under room temperature. The physico-chemical parameters viz., pH, titratable acidity, fat, free fatty acids, sensory and antioxidant properties were evaluated periodically at an interval of 3 days upto 9 days. The  result revealed that sensory evaluation of khoa was not influenced by the presence of 0.5 per cent aqueous extract of betel leaves up to 9 days of storage period with an overall acceptability score of 6.83. The physico- chemical properties of khoa showed an increasing trend in acidity and decrease of pH as the storage period progresses. The free fatty acids levels were well within the prescribed limit because of antioxidant properties exhibited by the aqueous extract of betel leaves. From the study, it was concluded that khoa with 0.5 aqueous extract of betel leaves restricted the production of free fatty acid compared to control due to antioxidant property of betel leaves.

Animals of all ages are susceptible for chocolate toxicity affecting many organ systems. The case presented here is of male German shepherd aged 4 years was accidentally encountered with chocolate toxicity with excessive salivation, vomition, diarrhoea, restlessness and incoordination like systems. The dog was treated symptomatically using rehydrated fluids, atropine sulphate and dexamethasone along with other supportive medication immediately. The dog was recovered completely within week of post treatment. 

Sub-adult Macrobrachium rosenbergii were reared in plastic tank and fed on Highly Unsaturated Fatty Acids (HUFA) enriched Artemia, unenriched Artemia and commercial feed in order to investigate the relationship of moulting to growth. Moulting frequency was found to vary according to diet. HUFA enriched artemia fed sub-adults had greater frequency of moulting than other feed.

The present study was aimed to investigate the presence of Escherichia coli (E.coli) in raw chicken meat samples collected from retail shops, as well as the biofilm-forming ability of field isolates, and to characterize different adhesion genes. Out of 20 chicken meat samples, 17 (85%) were positive for E. coli. Fifteen E. coli strains were characterized by PCR using the 16S rDNA primers and all the isolates were positive which confirmed that all the isolates were E.coli. Out of the 15 confirmed E.coli field isolates which were subjected to biofilm-forming assay, 46% of them were found to be strong biofilm producers. While all the isolates were screened for the presence of adhesion genes viz. luxS, csgA, fimH, fimA, and papC, the adhesion gene luxS was detected in all the strains (100%). The other adhesion genes csgA, fimH and fimA were detected in 93%, 93%, and 73% of the isolates, respectively. The E. coli field isolates were screened blaTEM gene was detected in only four strains, which was categorized under strong biofilm producers. This study demonstrated the presence of biofilm forming E. coli in the raw chicken meat samples as contaminants, causing spoilage and potentially posing risk to consumer’s health and safety.

This case report details the episiotomy approach employed in managing vulval hypoplasia in a two year old Miniature Pomeranian bitch. The animal was presented to the Teaching Veterinary Clinical Complex, Veterinary Gynaecology and Obstetrical Unit, Madras Veterinary College, displaying a history of greenish black discharge and continuous straining for two hours. The animal was bred before 64 days. Physical examination revealed a small vaginal opening, measuring approximately 1.5 cm in length. Digital examination indicated fetal hind limbs and tail extending into the vaginal passage, while all other vital parameters were within the normal range. Attempts to induce uterine contractions using Inj. Oxytocin and 10 % Calcium gluconate in 5 % DNS proved unsuccessful. Therefore, under local anesthesia (2 % Lignocaine injection), median episiotomy was made and a single live male puppy was successfully delivered with mild traction. Closure of the incision site was accomplished using PGA 1/0 with a simple interrupted suture pattern. The patient had uneventful recovery after 5 day treatment regimen, involving a single dose of subcutaneous Inj. Cefovecin (antibiotic) and anti-inflammatory drugs, along with meticulous wound management.
