Phenotypic and genetic parameters of feed efficiency in Charolais bulls - Part 1. Correlations across test station and field conditions under contrasting fattening diets.

Abstract excerpt

In the French Charolais breeding programme, feed efficiency traits are routinely evaluated in sires fed a cellulose-rich pelleted concentrate with a moderate energy density. However, this diet differs considerably from the silage-based diets commonly used in commercial farms. This study aimed to assess whether selection for feed efficiency under a cellulose-rich pelleted diet remains effective when progeny is...
