Genetic variance components for residual feed intake and feed conversion ratio and their correlations with other production traits in beef bulls



Genetic variance components for residual feed intake and feed conversion ratio and their correlations with other production traits in beef bulls



South African Journal of Animal Science 34(4): 257-264



Feeding costs of animals is a major determinant of profitability in livestock production enterprises. Genetic selection to improve feed efficiency aims to reduce feeding cost in beef cattle and thereby improve profitability. This study estimated genetic (co)variances between weaning weight and other production, reproduction and efficiency traits.
