Abstract
Data are tabulated for body weight at various ages up to 2 yr of 565 buffalo heifers; birth weight and body weight at 2 yr averaged 29.06 and 348.54 kg resp. Body weights at 36 and 52 wk and at 15, 18 and 21 mth were significantly affected by season of calving, with calves born in Jan.-June tending to be heavier than those born in July-Dec. All body weights, except those at birth and 15 mth, had high h2s, ranging from 0.43 to 1.19. There were high phenotypic and genetic correlations among most of the different body weights, and almost all the body weights were correlated negatively with age at 1st calving and positively with 1st-lactation milk yield; data are tabulated. It was concluded that the body weights most suitable for selection purposes were those at 4 and 12 wk and at 18 mth.
