Comparison of different diets for broiler turkeys
Abstract
Due to the ban of meat and bone meal, the feed industry is looking for alternative protein sources for turkeys. Mostly, soybean meal percentage is increased in order to meet the recommended dietary protein levels. Recent observations in the field such as growth depression, an increased variability within and between flocks, decreased breast muscle percentage in male turkeys and skeletal disorders are frequently claimed to be linked to amino acid imbalances, a surplus of dietary potassium because of a high soybean meal content in the ration, and possibly to a limited synthesis and intake of carnitine. Therefore an experiment is conducted in which either soybean meal alone or soybean meal plus fishmeal or soybean meal plus fishmeal plus a milk-byproduct are used as main protein sources (treatments 1 to 3) in turkey grower diets I and II. In treatment 4, a diet based on soybean meal is supplemented with L-Carnitine. Traits to be monitored include growth, carcass traits, meat quality, bone ash and selected immunological parameters.
