    GENETIC STUDIES ON LOCAL GOATS IN MANDYA DISTRICT OF KARNATAKA
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2016-05) SIDDALINGA MURTHY, H. K.; (M.R. JAYASHANKAR; K. ANIL KUMAR); C.S. NAGARAJA; H.N. NARASIMAHA MURTHY; K. SATHYANARAYAN; R. BHASKARAN
    A study was undertaken on local goats in Mandya district of Karnataka for various morphological characters, production and reproduction parameters, heritability of body weight at different ages and to develop prediction equations for adult body weight. Characteristic features of the goats were predominantly black colour of coat, eyelid, muzzle and hooves, leafy structured and pendulous ears, straight forehead, absence of beard and wattles and medium sized tail. Among horned goats 76.20 per cent had straight horns with upward backward orientation. Overall least squares means for body weight at three, six, nine, twelve month and adult goats were 9.41±0.12, 15.44±0.09, 19.46±0.09, 21.87±0.09 and 27.20±0.05 kg, respectively. Males were significantly (P≤0.01) heavier than females in all age groups. Single born kids were heavier than twin and triplet born kids. Effects of sex, type of birth and location/ centre on all body measurements were significant. Overall mean age at first conception, age at first kidding, kidding interval and service period in Mandya local goats were 398.94±3.31, 550.07±3.31, 276.00±2.17 and 125.47±0.93 days, respectively, and were significantly affected by year, season and type of birth. Heritability estimates of body weight were 0.36±0.03, 0.29±0.02, 0.27±0.04 and 0.24±0.02 at three, six, nine and twelve months, respectively. Body weight was positively and highly significantly correlated with all the four body measurements viz., height at withers (0.80), body length (0.96), chest girth (0.94) and paunch girth (0.94). Multiple regression analysis indicated that Height at Withers (X1) in combination with Body Length (X2) and Chest Girth (X3) would significantly improve accuracy of predictions.
