Abstract

This experiment was conducted to investigate the assumed efficacy of 65% on the product basis of methionine hydroxy analog (OH-Met, 88% aqueous solution of DL-2-hydroxy-4-(methylthio) butanoic acid) relative to DL-methionine (DL-Met) in broiler chickens. A total of 792-day-old male chickens were randomly allotted to 7 dietary treatments consisting of a methionine deficient-basal diet based on corn-soybean meal and 6 different diets obtained by supplying the basal diet with methionine at 3 levels (25, 100 and 125%; levels of addition relative to the required amount of additional Met to meet SID Met + Cys requirements) from either DL-Met or OH-Met at a ratio of 65:100 (DL-Met to OH-Met on a product basis) in the corresponding treatments.

通过测量肉鸡的生长性能、胴体性状、GHR和IGF-I表达，对蛋氨酸羟基类似物与dl -蛋氨酸的功效进行研究

本试验旨在探讨65%蛋氨酸羟基类似物(OH-Met)、88% dl -2-羟基-4-(甲基硫)丁酸水溶液相对于dl -蛋氨酸(DL-Met)对肉鸡的功效。试验选取792日龄雄性鸡，随机分为7组饲粮处理，分别为以玉米-豆粕为基础的蛋氨酸缺乏-基础饲粮和在基础饲粮中按3个水平(25,100和125%;在相应的处理中，DL-Met或OH-Met的添加水平相对于满足SID Met + Cys要求所需的额外Met量，比例为65:100 (DL-Met与OH-Met以产品为基础)。
