Digestible Lysine Requirement of Liuzhou Mahua Broilers at Different Growth Stages
Experiments were conducted to determine the digestible lysine (DLys) requirement of Liuzhou Mahua broilers from 1 to 21 d and from 22 to 42 d of age. Monofactorial design was adopted in this study. 1200 one-day-old healthy broiler chicks were divided randomly and evenly into five treatments, and were all fed with isoenergetic diet (with ME of 3.0 Mcal/kg) but with graded levels of DLys: 1.22%, ...
متن کاملRequirement of the laying hen for apparent fecal digestible lysine.
A study was conducted to determine the requirement for lysine of a White Leghorn strain of hens with a body weight of approximately 1,600 g. Before starting the experiment, apparent fecal digestibility of amino acids of the basal diet was determined in an in vivo digestibility trial with six individually housed hens. The basal diet used was based on corn and soybean meal and contained 0.65% tot...
متن کاملDigestible Lysine Requirement of Female Turkeys During the Starter Period1,2
Three experiments were conducted to determine the digestible lysine requirement of female turkey poults during the starter period. Birds were fed a standard corn-soybean meal diet until the onset of each trial and were then randomly assigned to treatments that were fed for 2 wk. Dietary treatments included titrated levels of digestible lysine (1.18 to 1.72%) added to a basal corn-soybean meal d...

متن کاملreevaluation of the digestible lysine requirement of arian male broiler chicks by different diets with cottonseed meal
an experiment was conducted to reevaluate the digestible lysine requirement of arian male broilers by comparing the performance of chicks fed different levels of cottonseed meal (csm) on a total amino acid (aa) versus a digestible aa basis. four hundred and thirty two (432) arian male broiler chicks were allotted to 18 treatments with four repli-cates of six chicks each in a completely randomiz...
