Estimation and consequences of direct-maternal genetic and environmental covariances in models for genetic evaluation in broilers

CONCLUSIONS: In this paper, we propose a simple approach to estimate the environmental direct-maternal covariance using standard software for REML analysis. The genetic covariance between dam and offspring was negative whereas the corresponding environmental covariance was positive. Considering both covariances in models for genetic evaluation increased the accuracy of predicted breeding values.PMID:37550635 | DOI:10.1186/s12711-023-00829-8
