The study designed to assess the normal reproductive tract involution in postpartum crossbred Jersey cows. Pluriparous crossbred Jersey cows (n = 10) which had recently calved were subjected to ultrasonographic assessment for postpartum involution once in two days till complete involution. The results showed that the involution time required for the vagina and cervix was 23 and 29 days respectively. The Mean ± SE of vaginal and cervical involution (cm) varied from 2.15±0.07 to 1.12±0.07 and 3.76±0.10 to 1.74±0.09 respectively. The uterine involution (cm) of gravid and non-gravid horn diverge from 4.27±0.12 and 3.47±0.14 to 1.89±0.13 and 1.67±0.14 respectively from day 4 to 23. The present findings document the reference value and period of reproductive tract postpartum involution in crossbred Jersey cows.   

Eight numbers of dung samples were collected from bovine calves aged between 6-9 months in Thalayamangalam village, Orathanadu Taluk, Thanjavur district with the history of chronic watery diarrhoea and jowl oedema. Gross examination of dung samples revealed foul smelling with absence of segments of tapeworms. Dung samples were screened by using sedimentation technique for the presence of parasitic eggs/ova. Microscopical examination revealed the presence of spindle shaped eggs having anterior spine and active miracidium inside the eggs. Based on the morphological features of the parasitic egg, it was diagnosed as Schistosoma spindale infection in calves.

A female Ongole calf aged one year and nine months was found to have nodular development around the left eye and neck region. Clinical examination revealed that the calf had cutaneous papilloma (wart), which was treated with autohemotherapy, ivermectin and levamisole injections along with placement of a ligature around wart's base. On the third day of treatment, a large papilloma on the left lower eyelid dried up and sloughed off. On the tenth day of therapy, the warts on the upper eyelid and neck began to dry and flake off, leaving behind barely visible scars at the original growth sites. The animal underwent an uncomplicated recovery and completely recovered from the ailment.

A six-year-old Siberian husky bitch was presented to Small Animal Gynaecology and Obstetrics Unit, Madras Veterinary College Teaching Hospital, with a history of proestrus bleeding and prolonged breeding failure due to shyness. Based on progesterone value (8 ng/mL, artificial insemination was done. On day 45 post AI, ultrasonographic examination revealed the presence of a viable foetus and lateral abdominal radiography showed the presence of a single foetus. Based on the observations, the owner was made aware of chances of risk of dystocia due to single puppy syndrome and the case was kept under observation. However, the case was presented on day 65 of gestation with signs of inappetence and greenish black vaginal discharge for the past 6 hrs. Based on the Ultrasound examination, Radiography and progesterone concentration, the case was diagnosed as dystocia due to single puppy syndrome. Under local anaesthesia, episiotomy was performed and a viable foetus (650 gm) was delivered. The episiotomy wound was closed in simple interrupted suture pattern using polyamide (1-0). After one week of  postoperative care, the bitch had an uneventful recovery.

The prevalence of Babesia infection was studied in newly purchased Tellicherry goats from Thalasserry, Kerala State to a private goat farm at Chennai. A total number of 168 goats were examined for the presence of Babesia. The study revealed that 58 (34.5%) goats were infected with Babesia ovis. The prevalence of Babesia infection between males and females and different age groups of goats was non-significant. Infected goats showed varying clinical signs of inappetence, depression, increased respiratory rate, weakness, coughing, nasal discharge, ocular discharge, diarrhea,   body temperature ranging 39.5- 41.2oC and abortion. Blood parameters revealed decrease in total red blood cells (RBC) count, haemoglobin concentration (Hb), Volume of packed red cells (VPRC), platelets counts and increase in lymphocyte and neutrophil count.

A seven year old female Doberman dog was presented with the history of dullness, anorexia and dysuria for three days. Abdominal palpation revealed distended bladder, which was confirmed by plain radiography and ultrasonography on Neurological examination animal was found to be normal. On manual compression of the bladder urine was not evacuated, therefore by catheterization was performed and no obstruction was found; around three litres of urine was drained. The animal was treated with oral Diazepam, @ 0.04mg/kg, Prazosin, 1mg/15 kg and Bethanechol, @ 2mg/kg bd. wt. On fourth day of treatment, the animal was able to urinate normally and it was advised to continue the treatment for two weeks. The animal had an unevenful recovery.

The study was structured to find out the seasonal influences on birth of piglets in tropical condition with the objective of probability in the birth of male and female piglets from 80 farrowing records for the period from 2017 to 2021. Depending on the season, male piglets are in more demand since they have to anticipate the demand for meat during festivals and other annual events. The parameters studied from farrowing records are litter size at birth and at weaning (42nd day). From this study, highest probability of male piglets were born during south west monsoon season where as the female piglets were born during winter season however, the pooled sex of piglets were born highest in winter season. It could be useful to the farmers who are in need of piglets for either meat production or breeding purpose.

Incubation centers are providing office spaces, access to advanced laboratory setups, farm facilities, clinical spaces, and comprehensive mentorship encompassing technical, legal, and financial guidance to the incubatees. The activities of VIF @ TANUVAS regarding areas of interest of 62 incubatees, products and productization, grants, ideas, and awareness programs were analysed for the period from 2019 to 2023. Among the area of interest of the incubatees, most of the incubatees (85 %) are working in the domain of Veterinary while 15% of the incubatees are working in the area of life sciences. Among the Veterinary related ideas, the majority of incubatees are interested in doing research in the development of diagnostic kits 26.41%, followed by Feed and Feed supplements (24.52%) whereas life sciences-related ideas are majorly chosen for drug discovery. Out of 62 ideas, 23 products were developed with a percentage of 37.1. Out of these 13 incubatees, 5 received grants (38.46%) from the Government of India (Central funds), while the remaining 8 (61.54%) received funding from the Government of Tamil Nadu (State funds). The highest number (52.81%) of ideas obtained during the year 2023 followed by 27.3% during 2021, 10.45% during 2020, and 9.41% during 2022 with more ideas from Madras Veterinary College, Chennai. This study concludes that The outcome of the product is directly proportionate to their ideas. 

A study was conducted in four flood-prone villages at Krishi Vigyan Kendra, Assam Agricultural University, Dhubri to assess the production performance of Khaki Campbell ducks and the economics of rearing them under NICRA (National Innovations in Climate Resilient Agriculture) project. A total of 10 farmers were selected from Dhubri village on the basis of their experience in duck farming. Two hundred day-old Khaki Campbell ducklings, twenty numbers irrespective of sex per household, were distributed and reared up to 72 weeks. On attaining 30th week of age, the male ducks were sold out. The data including body weight, mortality, age at first egg and egg production were recorded. The average age at first egg was 163.0±3.6 days, and 30th  week mean body weight was 1.8±0.1 kg. The mean egg production and mortality rate were 180.8±4.1 and 13% respectively during the study period. It was found from the study that Khaki Campbell duck farming has contributed notably to the livelihood of the rural farmers with benefit-cost ratio of 1.87. 

A two year-old queen cat with unknown mating history revealed absence of clear indication of positive pregnancy but single fluid filled anechoic structure noticed on ultrasonography. Spaying was performed and clear watery sterile fluid in the uterus confirmed it as a case of hydrometra.
