Performances et qualité de la viande de taurillons recevant des régimes riches en concentré a base de parois ou d’amidon et lipides

Résumé

This study is aimed at comparing fattening performances, carcass and meat quality in Charolais bulls slaughtered at 18 months, and fed concentrate diets, rich either in fibre (F) or in starch plus lipids from linseed (SL). Concentrates were given ad libitum, available ad libitum straw was the unique forage. A total of 112 bulls were used. Bulls fed the SL diet had a lower dry matter intake but a similar net energy intake. Their body weight gain, feed efficiency, and weight at slaughter were higher and their carcass was fatter than for bulls fed the F diet. Their fatty acid content of muscles was also higher for total, saturated, cis and trans monounsaturated, and n-3 polyunsaturated fatty acids. The polyunsaturated / saturated ratio did not vary with diet, but the n-6/n-3 ratio was lower for diet SL than for diet F.
