The study focuses on the effect of breed on the body weights and average daily gains (ADGs) during pre-weaning (birth4 weeks) and post-weaning (4-16weeks) of Flemish Giant, Californian White and their Crossbreds. The data was subjected to one way analysis of variance. The difference between the means was tested by significance using Duncan's multiple range test by programming and processing in computer. The overall least squares mean body weights at birth, 1, 2, 3 and 4 weeks of age were 52.38 ± 0.69, 110.58 ± 1.77, 169.97 ± 3.23, 254.35 ± 5.77 and 398.13 ± 8.44g, respectively. The overall least square means for post-weaning body weights at 6, 8, 10, 12, 14 and 16 weeks of age were 620.90 ± 13.11, 862.50 ± 18.10, 1072.88 ± 21.40, 1302.47 ± 24.69, 1535.12 ± 26.90 and 1733.51 ± 29.09g, respectively. The influence of breed was found to be significant on body weights at all the ages except at birth and on ADGs at all ages during pre-weaning and most of the ages during post-weaning. Feed efficiency of Flemish Giant, Californian White and their crossbreds were studied during post weaning period and observed that FCR (kg DMI/kg gain) were 3.46, 3.99 and 3.86.
