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.

A primiparous Jersey cow was brought in lateral recumbency with the history of straining and past occurrence of antepartum prolapse a week before. Vaginal examination revealed incomplete two finger cervical dilatation with a very thin cervical rim. Cervicotomy was performed to remove the live male fetus and the animal recovered uneventfully.

Parasitic infestation is the primary aetiology of anaemia in goats. Chronic parasitic infestation being the most common cause for severe anaemia in addition to the elimination of aetiology, supportive therapy is necessary for the early regain of normal physiological and haemato-biochemical parameters. The present study was conducted at the Veterinary clinical complex, Veterinary College, Bidar. Six severely anaemic goats were selected for the present study to know the efficacy of iron sucrose as supportive therapy. Rectal temperature, heart rate and respiratory rate were recorded as per the standard procedures. Haemato-biochemical parameters were estimated on day 0 and day 15 of post therapy as per the standard procedures. Goats were promptly treated for the primary complaint, dipped, and dewormed to eliminate the Endecto parasites. Selected goats were supplemented with 50 mg of iron sucrose on every alternate day four times in 100 mL normal saline solution by slow intravenous route. A significant (p< 0.05) improvement was observed in physiological and haemato-biochemical parameters after 15 days of post therapy. 

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.

A biological trial was conducted at Department of Poultry Science, Madras Veterinary College, Chennai to evaluate the effect of inclusion of RDDGS in commercial broiler diet on hematological, serum biochemical parameters. A total of 144 commercial day-old broiler chickens were allotted to four treatments with three replicates and 12 birds per replicate. Experimental diets were prepared by including RDDGS at 0, 5, 10, 15% at the expense of soyabean meal was prepared to be nearly isocaloric and isonitrogenous as per BIS (2007) standards. At the end of the experiment blood was collected from one male and one female from each replicate and analyzed for serum biochemical and hematological parameters. Statistical analysis of data revealed that there was no significant (P>0.05) difference in the hematological, serum biochemical and intestinal histomorphology parameters. It can be concluded that the RDDGS can be included up to 15% in commercial broiler diets without effecting the hematological and serum biochemical parameters.

Samples of feed ingredients were collected from the truck loads that arrived at feed processing unit located in Veterinary College and Research Institute, Orathanadu, Thanjavur, Tamil Nadu, India. Physical examination of collected samples was carried out prior to their chemical evaluation. Chemical evaluation of feed samples revealed that moisture content in maize grain ranged from 8.47% to 17.25% and high moisture was observed in samples received during the monsoon season (September to December). The crude protein content of protein supplements viz., soyabean meal, coconut oil cake, coconut deoiled cake (DOC), groundnut cake, groundnut deoiled cake, delinted decorticated cotton seed cake, sunflower deoiled cake and gingelly oil cake were 45.49, 25.11, 24.47, 36.92, 43.89, 35.36, 30.21 and 29.89 per cent on dry matter basis, respectively. The crude protein (% DMB) and crude fiber (% DMB) content of deoiled rice bran, rice bran and wheat bran were 15.47 and 16.13, 7.55 and 36.26, 14.26 and 9.47, respectively. Due to the high moisture content in maize grain 8.77% of the total truck loads of this ingredient received at the processing unit were rejected. Similarly, of the total truck loads of oil cakes received at the processing unit 20.93 % of soyabean meal, 12.5% of coconut oil cake, 20 % of coconut DOC, 22.22% of cotton seed cake and 33.33% of gingelly oil cake were rejected due to the lower crude protein and higher crude fiber contents. All truck loads of rice bran (100 %) were rejected due to their lower crude protein, higher crude fiber and Acid Insoluble Ash (AIA) content. The study thus revealed that quality control measures are essential to check the entry of poor quality raw materials before processing the feed.

Growth dynamics of buffalo population and milk production and productivity in Tamil Nadu was analysed. Point to point annual compound growth rate (ACGR) was calculated to assess the trend in buffalo population and continuous annual compound growth rate (ACGR) for milk production and productivity. The share of Tamil Nadu to National buffalo population decreased from 5.29 to 0.72 % (1951 to 2012) and the buffalo milk production reduced from 4.01 to 0.46% (2001-02 to 2015-16). The ACGR of buffalo population in Tamil Nadu was -17.23% during the last inter-census period (2007-12). North Eastern and Cauvery Delta agro-climatic zones of Tamil Nadu registered high negative growth. The annual compound growth rate of buffalo milk production during 2011-12 to 2015-16 in  Southern zone was -27.37% and it was - 21.72% in North Eastern and -20.93 % in Cauvery Delta zone with overall ACGR of -16.85%. The ACGR of buffalo milk productivity was 0.61% (2001-02 to 2015-16) in Tamil Nadu, while the rate was 1.58% in India. Hence, rigorous implementation of buffalo development programmes is a prime requisite and need of the hour for improving buffalo population and milk production in Tamil Nadu.

The diseases in poultry cause huge losses in the form of mortality in acute infections or as substandard performance due to chronic illness. Biosecurity and vaccination are considered as two important primary strategies for disease prevention in poultry. On the other hand, breeding for disease resistance is an alternate strategy to combat the damages of diseases. Although, attempts were initiated to develop disease resistant poultry by breeding almost a century before, this branch of science renewed the interest among scientists because of catastrophic emerging and reemerging diseases like Avian influenza. It has proven over a period of time that poultry  exhibits genetic resistance to viral diseases like avian leukosis complex, Marek’s disease, avian influenza and Newcastle disease, bacterial disease like salmonellosis and may parasitic infestations. The key genes responsible for resistance to specific diseases have also been demonstrated. The breeding attempts for developing disease resistant poultry has yielded positive results with varying degree of success. The advent of sophisticated molecular methods like genomic selection using highdensity SNP chips, RNA-seq technique and identification of key marker genes and transgenesis could complement the conventional breeding methods to a larger extent in developing disease resistant poultry.

Food wastes of vegetable origin fed to pigs contained significantly (P<0.05) higher metabolizable energy, comparable crude protein and lower dry matter, crude fibre, total ash, calcium, phosphorus, copper and iron compared to pregnant gilt feed (NRC, 1998). To optimize the food wastes for nutrients to be comparable with pregnant gilt feed, de-oiled rice bran at 33% and mineral mixture at 2% were added as supplement for food wastes on DM basis. A feeding trial was conducted in 18 large white Yorkshire crossbred bred gilts. The treatment groups were pregnant gilt feed (T 1 ), food wastes as sole feed (T 2 ) and food wastes + evolved supplement (T 3 ) with 6 animals in each treatment. The gestation body weight gain and gestation length did not differ (P<0.05) significantly among the treatment groups. No significant difference in litter size, litter weight at birth and weaning weight were observed among the treatment groups. Higher per cent stillborns and per cent piglet mortality was observed in T 2 compared to T 1 and T 3 . The average birth weight and weaning weight of piglets were significantly (P<0.05) lower in T 2 . Supplementation to food wastes (T 3 ) increased the piglet birth weight and weaning weight comparable to T 1 . Sows body weight after farrowing and at the time of weaning and lactation body weight loss did not differ significantly (P<0.05) among the treatment groups.

The possibility of production of hormone-free all male Nile tilapia (Oreochromis niloticus) in F2  generation, through the production of YY super males in F1 generation, was investigated in the present study. Feminization of Nile tilapia was carried out using the hormone, 17 beta estradiol at 100, 200 and 300 mg/kg concentrations, orally through feed. The hormone enhanced the growth significantly (p<0.05) both in terms of length (55.39±0.67 cm) and weight (55.39±0.67 g) at 300 mg/kg feed when compared to other treatments and control. With the increasing concentrations (300 mg/kg) of the hormone, the survival rate decreased significantly (p<0.05) to 62±1.53%. The feminization rates increased significantly (p<0.05) with increasing concentrations of the hormone, with the highest feminization percentage of 98.27±0.87% observed at 300 mg/kg concentration of the hormone. Two fish from F generation with the PIT tag numbers 81 and 88 produced all male progeny which was confirmed through morphological examination. The genotype of these two YY supermales was re-confirmed through molecular genotyping with the help of primers amhX1+36 and amhdY+5 DNA markers, specific to X and Y chromosomes, respectively using RAPD-PCR.
