    STUDIES ON METABOLIC GROWTH INDICATORS DURING DIFFERENT STAGES OF GROWTH IN BANNUR FEMALE SHEEP
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR-585401, 2018-09) VEENA, M. P.; Dr. M. NARAYANA SWAMY
    The present study was conducted to ascertain the metabolic growth indicators during different stages of growth in Bannur female sheep maintained at Bandur Breeding Farm, Danagur Village, Malavalli Taluk, Mandya District. Twenty four female sheep divided into four groups with six animals in each group such as Group I (>3 to 5 months), Group II (>5 to 7 months), Group III (>7 to 9 months) and Group IV (>9 to 11 months) were utilized in the present study. The blood samples were collected from jugular vein at fortnightly intervals for two months (15th, 30th, 45th and 60th day). Each time about 5 to 8 ml of blood was collected in clot activated vacutainer. A drop of blood during collection was immediately utilized for estimation of blood glucose and β- hydroxybutyrate (BHB). Serum samples were immediately utilized for determination of alkaline phosphatase (ALP) and creatine kinase (CK) activity. In the present study it was found that the blood glucose, serum total protein, serum total cholesterol, leptin, insulin, estradiol, T3 and potassium levels were increased significantly in advance stages compared to early stage of growth. However, the BHB levels were constant in different age groups. T4 levels increased in advance growth period, calcium and phosphorus levels did not differ with respect to age. Growth hormone increased in the early stage, but ALP and CK activity reduced as the age advanced. Body weight increased from beginning to the completion of the study. It was concluded that the levels of blood glucose, BHB, leptin, insulin, GH, potassium, ALP, CK and body weight gain could be used as physiological indicators of growth in Bannur female sheep to ascertain growth and the same can be extrapolated to other breeds of sheep. Key words: Metabolic growth indicators,

    SERUM AND MILK COMPONENTS IN AMRIT MAHAL, HOLSTEIN FRIESIAN CROSSBRED AND JERSEY CROSSBRED COWS
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-09) PRAVEEN, V.; Dr. M. NARAYANA SWAMY
    The present study was undertaken in Amrit Mahal (Group I), Holstein Friesian crossbred (Group II) and Jersey crossbred (Group III) cows at third lactation to assess blood metabolic profile and milk components profile. A total of eighteen cows with six cows in each group were selected randomly from different dairy farms. The blood and milk samples were collected during fourth, eighth and twelfth weeks of lactation. The serum samples were subjected for the estimation of the levels of glucose, total protein, albumin, globulin, A/G ratio, urea nitrogen, total cholesterol, triglycerides, calcium, phosphorus, magnesium, sodium, potassium and chloride. The milk components such as percentage of lactose, fat, proteins and solids-not-fat were measured using ultrasonic lactoscan milk analyser. The pH of milk was measured using digital pH meter. The daily milk yield was also recorded. Serum components such as glucose, total protein and globulin were significantly higher during fourth week compared to twelfth week of lactation in Amrit Mahal cows. The serum lipid and mineral profile were higher in Amrit Mahal cows compared to crossbred cows. The milk profile of different parameters such as lactose, protein, fat and SNF were significantly higher in Amrit Mahal cows compared to crossbred cows. Whereas, milk yield and pH was higher in crossbred cows compared to Amrit Mahal cows. It was concluded that the levels of some of the serum and milk components were higher in Amrit Mahal cows compared to Holstein Friesian crossbred and Jersey crossbred cows. Therefore, Amrit Mahal cows should be conserved for further cross breeding programmes.
