Feed conversion

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal, which comprises simultaneously feeding to the animal protected protein meal and, in addition, protected lipid in effective amounts for synergistically improving the growth rate and modifying the carcass quality, wherein the ratio of protected protein meal to protected lipid is substantially the same as the ratio of carcass protein to fat of the animal.

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal, which comprises simultaneously feeding to the animal protected protein meal and, in addition, protected lipid in effective amounts for synergistically improving the growth rate and modifying the carcass quality, wherein the ratio of protected protein meal to protected lipid is between from about 3:1 protein to lipid to about 1:1.

A synergistic composition for improving the growth rate and modifying the carcass quality of a ruminant livestock animal which comprises protected protein meal and, in addition, protected lipid in effective amounts for synergistically improving the growth rate and modifying the carcass quality.

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal comprising simultaneously feeding to the animal a feed comprising by weight 15% protected sunflower seed meal and 10% to 15% protected canola oil seed.

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal comprising simultaneously feeding to the animal a feed comprising grain, 15% protected sunflower seed meal by weight and 10% protected cotton seed lipid by weight.

A method of improving the growth rate and modifying the carcass quality of a ruminant livestock animal comprising simultaneously feeding to the animal a feed comprising grain, an ionophore, 15% protected sunflower seed meal by weight and 10% protected cotton seed lipid by weight.
