Genetic analysis of diallel crosses in laying hens. I. Effects of hatch and estimates of additive, maternal, specific and reciprocal effects



Genetic analysis of diallel crosses in laying hens. I. Effects of hatch and estimates of additive, maternal, specific and reciprocal effects



Archos zootecnia, 17: 339-361



Diallel crossings were carried out with 666 White Leghorn hens of 4 inbred strains with an inbreeding coefficient of 0.65. Hatch had a significant effect on weight of bird at 3 wk, 12 wk and 500 days, on sexual maturity, and on egg weight and egg production at 500 days. At 3 wk of age, additive and maternal effects were the most significant, at 12 wk specific and maternal, and at 500 days specific and reciprocal effects.
