本试验旨在分析湖南省6种不同地区菜籽粕的18种氨基酸含量,测定14和28日龄肉仔鸡对6种不同地区菜籽粕中氨基酸的标准回肠消化率,并建立赖氨酸、蛋氨酸、色氨酸及苏氨酸标准回肠消化率的预测方程.试验共选取700羽体重和健康状况一致的1日龄爱拔益加(AA)肉仔鸡,根据日龄分别进行2个阶段的试验.第1阶段(7 ~ 14日龄) :将420羽肉仔鸡随机分为7个处理,每个处理10个重复,每个重复6羽;第2阶段(21 ~ 28日龄) :将280羽肉仔鸡随机分为7个处理,每个处理10个重复,每个重复4羽.2个阶段中的7个处理分别为6个不同地区的菜籽粕采用全替代法设计的试验饲粮组和1个无氮饲粮组.分别在14和28日龄收集试验鸡回肠食糜用...

This experiment was aimed to analyze the contents of 18 kinds of amino acids of rapeseed meals in 6 different areas from Hunan province, determine the amino acid standard ileal digestibility in rapeseed meals from 6 different areas in 14-day-old and 28-day-old broilers and establish the prediction equations of standard il-eal digestibility of lysine ( Lys) , methionine ( Met) , tryptophan ( Trp) and threonine ( Thr) . Seven hundred 1-day-old Arbor Acres ( AA) broiler chickens were divided into two test stages according to their age. The first stage ( 7 to 14 days of age) selected 420 broiler c...
