(Co)variances for reproduction, egg weight and chick weight in ostriches
@article{Cloete2004CovariancesFR, title={(Co)variances for reproduction, egg weight and chick weight in ostriches}, author={S. Cloete and K. Bunter and Z. Brand and H. Lambrechts}, journal={South African Journal of Animal Science}, year={2004}, volume={34}, pages={17-19} }
The study investigated genetic parameters for egg and chick production recorded over an 8-month breeding season, as well as average egg and chick weight for pair-bred ostrich females. Estimates of h² were moderate for reproduction traits and very high for average egg and chick weight, where all traits were expressed as a trait of the dam. Genetic and phenotypic correlations were positive in sign for all trait combinations. Selection for an increased reproduction rate would thus not lead to an… Expand
