Fats and amino acids in broiler rations

Abstract

An attempt has been made to establish, under the conditions prevailing in the United Kingdom, an optimum energy‐protein balance for broiler starter rations. It has been shown that either increasing the supply of protein or energy‐yielding nutrients in the starter diet can lead to an improvement in overall growth performance. It is suggested that such an advantage is more apparent with cocks than pullets and more likely to be observed with birds of high growth potential. No particular merit could be shown for the use of sesame meal supplemented with lysine as the sole source of protein‐rich material.
