A biological trial was conducted to investigate the effect of bacteriophage on carcass characteristics of commercial broilers with or without bacterial challenge. Totally 180 day old Vencobb broiler chicks were randomly allotted into five dietary treatments designated as T1 to T5 with each treatment replicated thrice. T1 and T2 served as negative and positive control respectively, while birds in T3, T4 and T5 were exposed to E. coli on different days during 35 days course. Dietary treatments included T1 - basal diet, T2 - basal diet with bacteriophage in feed (50 mg/bird/ day up to 7th day and 25 mg/bird/day up to 35th day), T3 without bacteriophage, T4-bacteriophage in feed (50 mg/bird/day up to 35th day) and T5 - bacteriophage in feed (50 mg/bird/day up to 7th day and 25mg/bird/ day up to 35th day). E. coli was introduced orally in groups T3 and T4 on day 10, while T5 on day 26 (106 CFU/ bird). The bacteriophage supplementation to E. coli challenged birds had significantly increased the weights of eviscerated carcass, giblets, ready-to-cook meat; the cut-up parts like breast, back and drumstick compared to non-supplemented group. Results shed light on the potential benefits of bacteriophage as a natural alternate approach to antibiotic growth promotors in broiler production.

A three year old, male, Dachshund dog, weighing 10 Kg was presented to Veterinary College Hospital, Hassan with the history of snake bite (Russell’s viper). On physical examination, animal was dull and depressed, face was swollen and fang marks were observed on the right side of the face and blood tinged fluid was oozing from the bitten area. Animal was evincing pain on palpation of swollen area. Haemato-biochemical findings were within the normal range except for thrombocytopenia. The case was diagnosed as snake envenomation and treated with polyvalent anti snake venom intravenously, along with 100 ml of 0.9 per cent normal saline, dexamethasone and antibiotics for 5 days. Animal made uneventful recovery after 5 days of treatment. 

With the aim to examine the effect of rearing systems on major meat quality traits in native ducks, appropriate experimental investigation was conducted. Research material included a total of 160 day-old native ducklings. The experiment was organized in two treatments with two replications each. Two different rearing systems were employed the intensive (cages) and extensive system (free-range). The native ducklings belonging to same hatch were procured from a local duck farmer and reared simultaneously for a period of ten weeks. Twelve ducks (six male and six female) from each treatment were chosen randomly and slaughtered at the end of rearing period to study meat quality traits in native ducks. Differences were significant (P<0.05) among sexes and rearing systems on pre slaughter live weight, eviscerated weight and various cut up parts, the corresponding values are higher for intensively reared ducks. Regarding sex, both male and female ducks exhibited differences considerably higher weight gain, carcass and cut up parts yield than that of female ducks.

A clinical parameter study was conducted to file the reference serum bio-chemical values of Bonnet macaques (Macaca radiata) reared under captivity. The animals were chemically restrained and six blood samples (3 males and 3 females) were collected from the saphenous vein and processed. In this study, the mean ± S.E. of estimated value of serum biochemical profiles were close to the normal range reported earlier. But, serum glucose level was less and serum level of phosphorus was comparatively high.

Restraining gadget for Indian poisonous snakes like Indian cobra and Russell’s Viper were designed, using available infrastructures. Tongs, collapsible tubes and bags were designed and applied in the poisonous snakes in order to have better restraining activities. These snakes reared at Guindy Snake Park Trust were successfully restrained, using the gadgets developed. However these gadgets were found not suitable for restraining procedure associated with Saw scaled viper and Common krait. The gadgets developed were useful for zoo veterinarians for control of these serpentines.

To improve the production performance of white Guinea fowl, selective breeding was carried out continuously for six generation. A total 1000 Guinea fowl hatching eggs were procured from various government institutions and private entrepreneurs, and subsequently keets were hatched out and base population was created. The production traits were given due importance during selective breeding for six generations to improve both body weight and egg production. The traits such as hatch weight 4th, 8th, 12th,16th and 24 week body weight (g), FCR, livability, age at sexual maturity (days), Hen – Day Egg Production (HDEP) and Hen - Housed Egg Production (HHEP), annual egg number, egg weight (g), adult livability, total and fertile hatchability (%) were studied in all six generations. The day-old chick weight of all six generations ranged from 26.46 to 28.10 g. The 4th and 8th week mean body weight of the first generation white Guinea fowl was 180.85g and 481.69 g respectively, which increased to 220.95 g and 494.13 g, respectively in 6th generation. Similarly, the 12th and 16th week body weights in 1st generation increased from 767.12 g to 805.29 g and 951.04 g to 1079.15 g, respectively, at 6th generation. The linear regression analysis of 4th and 8th week body weight over generations revealed significant increment of 7.59 g and 7.72 g, respectively, per generation. Similarly, the 12th and 24th week body weight in each generation had a positive change with high degree of goodness of fit. The 12 and 16th week FCR showed a positive change of high magnitude over generations. The hen day and hen housed egg production (29-51 weeks) from 1st generation to 6th generation increased from 39.26 to 40.55 % and 37.53 to 38.83 %, respectively, during the course of selection. The total and fertile egg hatchability also showed marked changes due to selection with values varying from 49.52 to 53.14 % and 71.37 to 72.38 % across the generations. This study concluded that the multi stage short-term selection can improve both body weight and egg production in white Guinea fowl.  

The present study aimed to develop and standardize RTD dal payasam prepared with coconut milk by replacing bovine milk by cooking dal (moong dal/ split yellow lentils) in coconut milk with added nuts, sugar and shredded coconut. The product was prepared with total solids of 22-23% as per commercial purpose. Three different trials (P1, P2 and P3) with varying quantities of dal (150g, 200g and 250g), jaggery (250g, 150g and 200g) and coconut milk of 200ml (based on preliminary study) was studied. The optimized dal payasam was filled in cans and retort processed at 121.1ºC and overpressure of 1.29 bar with steam pressure of 1 bar. Lethality time (F0) of 16.7 min and Total Process Time of 34.2 to 38.7 min was calculated by predictive thermal process modeling. Sensory evaluation of P1, P2 and P3 concluded that P3 with 250g moong dal, 200g jaggery, 200 ml coconut milk was highly preferred by sensory panelists. The finalized trial was further studied for its physico-chemical properties for 60 days at refrigerated (4±2ºC) and room temperature (25±2ºC). The study concluded that retort processed Ready-to-Drink dal payasam packed in cans was safe to consume upto 60 days of storage.

 Open fontanelle is a soft spot located on top of the head in a newborn due to incomplete fusion of the cranial bones. They are the normal structure in young puppies, especially in small breeds and get hardened by 9-12 weeks of age following fusion of growth plates in the skull. The aim of our study was to describe the presence, diagnosis and management of open fontanelle. A puppy was presented with the history of swelling over the frontal region, intermittent seizures for the past two weeks. Clinical examination revealed a swelling over the mid-frontal region of head. Radiographic examination of skull revealed hydrocephalus with open fontanelle.

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.

Animal body reacts to all kinds of injuries and stress to keep the homeostasis. Such resistance can be specific or non specific. Non specific innate resistance of the body like cytological and cytokine reactions including fever, leukocytoses etc. are known as acute phase response. In this response, there will be increase or decrease of serum concentration of particular proteins. These proteins are known as acute phase proteins. Measurement of serum concentration of these acute phase proteins are found to be useful in assessment of health status and prediction of diseases of the man and animals. Acute phase proteins like Serum amyloid A, C- reactive proteins, Haptoglobin, alpha 1 acid glycoprotein etc. are found to be more sensitive and specific than the routine diagnostic methods like white blood cell count. Use of acute phase proteins as biomarkers for animal disease diagnosis and health status assessment has got high potential in modern veterinary practice. Usefulness of the acute phase protein analysis in veterinary practice especially in dog, cat, cattle and pig practices is discussed in this review.
