Abstract:
A total of 4479 progenies covering three generations (S₁₂ to S₁₄) at ICAR-DPR, Hyderabad were utilized for the study. Overall least squares means of body weight at 0 day, 4, 8, 16, 20 and 40 weeks of age were 36.07±0.05g, 204.94±0.71g, 474.53±5.54g, 951.72±3.10g, 1162.24±4.19g 1426.26±5.71 g, respectively. The heritability estimates for body weights at different ages were studied. Heritability estimates for body weight at 0 day, 4, 8, 16, 20 and 40 weeks of age were 0.13±0.05, 0.09±0.03, 0.22±0.05, 0.19±0.06, 0.24±0.06 and 0.54±0.08. Hatch effect was significant (p≤0.01) on the body weights at 0 day, 4, 8, 16, 20 and 40 weeks of age. Generation was significantly affected all body weight traits.
