Oxidative stress is a common mechanism contributing to initiation and progression of hepatic damage in a variety of liver disorders. Hence, there is a great demand for the development of agents with potent antioxidant effect. The aim of the present investigation is to evaluate the efficacy of raw and nanoforms of resveratrol and silibinin as a hepatoprotective and an antioxidant against diethylnitrosamine induced hepatocellular damage. 0.01% diethylnitrosamine administration to rats resulted in significantly elevated levels of lipid peroxidation (LPO) and decreased levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), glutathione reductase (GSH) and total protein (TP) in the liver tissue. Post-treatment with the nano resveratrol (50 mg/kg), nano silibinin (50 mg/kg), raw resveratrol (50 mg/kg), raw silibinin (50 mg/kg) orally for 30 days significantly reversed the diethylnitrosamine induced alterations in the liver tissue and offered almost complete protection. The results from the present study indicate that both nano forms exhibit good hepatoprotective and antioxidant potential against diethylnitrosamine induced hepatocellular damage in rats as compared to raw forms.

Nutritional evaluation of different pulse chunnies was carried using Near Infrared Reflectance Spectroscopy (NIRS) and validated with wet analysis for inclusion in livestock feeds. The portable NIRS spectrophotometer FOSS XDS RCA and FOSS 6500 chemometrics software were used for the study. A total of 324 samples of four pulse chunnies (red gram (RGC), green gram (GGC), black gram (BLGC) and bengal gram (BGC)) were assessed using NIRS. It revealed that RGC had significantly (P<0.01) highest DM content than other three samples. The mean CP content was highest (P<0.01) in GGC and lowest in BGC and significantly (P<0.01) higher ether extract (EE) was recorded in BLGC and RGC and lowest in BGC samples. The ash content was significantly (P<0.01) highest in BLGC and lowest in RGC samples. Neutral detergent fibre (NDF), acid detergent fibre (ADF) and acid detergent lignin (ADL) contents were higher (P<0.01) in BGC and lower in GGC samples. Wet analysis shown, the DM content did not differ (P>0.05) among pulse chunni samples, while significantly (P<0.01) higher organic matter was recorded in RGC and lowest in BLGC samples. The CP was higher (P<0.01) in BLGC and lower in BGC and significantly (P<0.01) highest crude fibre recorded for BGC, RGC and was lowest in BLGC and GGC samples. Highest (P<0.05) EE was observed in BLGC while lowest in BGC. There was no significant (P>0.05) difference in nitrogen free extract among pulse chunnies, while ash content was significantly (P<0.01) higher in BLGC and lower in RGC samples. NDF, ADF and ADL were significantly (P<0.01) higher in BGC and lower in GGC samples. The study concludes that the NIRS technique can be used to screen large number of samples in lesser time for using them in livestock feed formulations as there is a high correlation between NIRS and conventional feed analysis.

Mammary tumours are considered as the most important neoplasms in dogs especially in sexually intact female dogs. Prognosis is directly associated with various factors such as tumour size, metastases, involvement of lymph node, tumour type and grade. Recently, tumour microenvironment (TME) has gained huge importance and proved to be a key regulator of breast cancer's biologic behaviour, according to mounting data. The capacity of extracellular matrix components like collagen to alter their intrinsic structure and alignment aids in tumour invasion and metastasis. We present a case study of 25 canine mammary tumours (CMTs), where the stroma associated with the malignancy was specifically considered while histomorphologically analysing the tumours. The majority of the tumours were malignant (96 per cent) and one was identified to be benign. Simple carcinomas made up the majority of tumours, followed by mixed types. Cancer associated stroma was assessed by routine H and E staining and additionally by performing immunohistochemistry technique with anti-cytokeratin antibody to access the relative abundance of neoplastic epithelial cells. Special stains such as Picrosirius red, Masson’s trichrome and Herovici were employed to demonstrate the desmoplastic stromal reaction and varying grades of collagen could be observed in the stroma of different tumours. The extent of fibroplasia was found to be directly proportional to the grade and size of tumour. Thus, results of the present study indicated that the cancer associated stroma significantly in fluence the CMT progression and clinical outcome.

An attempt was made to measure the comparative advantage of dairy farming among different occupational groups of rural Tamil Nadu (540 households and 2500 persons) for its poverty alleviation role. The most commonly used measures of poverty viz., head count index (P 0), poverty gap index (P1) and squared poverty gap (poverty severity) index (P2), the Watts index and average exit time from poverty were calculated. About 59 per cent of the total sample households and close to 65 per cent of sample population were found to stay below poverty line. P1 P2 and W index were observed to be the highest among agricultural labourers and the lowest among dairy farmers. At four per cent of hypothetical income growth rate, the time required to exit out of poverty was estimated to be the least for dairy farmers (4.66 years for buffalo and 4.91 years for cattle), followed by fishermen (5.09 years). Keeping in view of poverty reduction potential of dairy farming, it shall be included in poverty alleviation programmes. 

A pregnant graded Murrah buffalo at eight months of gestation in third parity having bilateral distension of abdomen was presented. The case was diagnosed as hydramnios and treated with dinoprost tromethamine, diethyl stilbesterol, valethamate bromide and dexamethasone. After 76 hours, cervix was dilated fully and trans-cervical amniocentesis was performed and approximately 60-70 litres of amniotic fluid was drained and a dead male fetus with cleft palate was delivered.

A one and half year old heifer was presented with a hard mass hanging from brisket region. The mass was oval shaped, 10 x15 cm in size, pedunculated with the base at the level of carpal joint. Cytological examination revealed melanocytes with the presence of numerous blackish melanin pigments in the cytoplasm. Histopathological examination revealed that the tumor was comprised of heavily pigmented spindle shaped cells, arranged in sheets with a large nuclei and abundant granular black pigment in the cytoplasm. Following surgical removal of the mass, the animal recovered with no recurrence. Based on clinical examination, cytology and histopathological findings, the growth was diagnosed as cutaneous melanoma.

A Large White Yorkshire male pubertal pig was presented with the history of sustained protrusion of penis for about six hours. Edema of the protracted penis was reduced. Manual repositioning and retension of glans penis into preputial cavity was carried out successfully. There was no recurrence.

This study is planned to assess the socio-economic profile, cost economics in feeding and impact of brewery waste utilization among dairy farmers in Vellore district of Tamil Nadu. For this purpose, a survey was conducted in six blocks with one village per block and 15 farmers per village constituting a total of 90 respondents. Data was collected through personal interview method with the help of pretested interview schedule. The survey results indicated that majority of the farmers are in the age of 33 - 47 years and the family size of the respondents is less than 5. More than 50% of the farmers had experience of 10 years in dairy farming practices and the annual income from dairy farming was higher than agriculture sector. All farmers were providing their milch animals with green and dry fodder and the total cost incurred varied from Rs.38.97/- to Rs.29.53/day/animal during milch period and from Rs. 31.66/- to Rs.25.38/day/animal during the dry period. In concentrate mixture, the main ingredients reported were bran, husk, rice gruel and oil cakes and total cost incurred varied from Rs.112.74 to Rs.43.04/day/animal during milch period and from Rs.73.25 to Rs.24.95/day/ animal during the dry period. The mean milk production varied between 5.37 lts to 9.51 lts/day/animal and the cost/ltr of milk varied between Rs.13.50 to Rs.15.95/ltr. It is imperative to note that 38.89% of the farmers were utilizing unconventional feeds such as tapioca powder, tamarind seed, brewery waste and dried distillers’ grain soluble (DDGS) to feed their dairy cattle. Also, from the survey it is inferred that dairy farmers should be sensitised more on the scientific ways of feeding lactating dairy cattle to augment milk production and thereby to increase their livelihood security.
