| 摘 要： | 用肉仔鸡进行为期1周(8～14日龄)的生长反应试验 ,用标准曲线及斜率比法测定了玉米、豆粕中胆碱生物学效价。按单因子试验设计 ,用艾维因商品代8日龄肉仔鸡160只 ,随机分为10个处理组 ,每组4个重复、每个重复4只鸡。通过在玉米淀粉酪蛋白纯合饲粮中分别添加胆碱(由氯化胆碱提供)0、300、600和900mg/kg,作出生长反应曲线。用玉米分别占42.21 %、72.24 %的两个玉米半纯合饲粮和豆粕比例分别为16.50 %、24.83 %的两个豆粕半纯合饲粮饲喂肉仔鸡 ,测出玉米和豆粕中胆碱生物学效价分别为57.47 %和45.97 %。用两个玉米 +豆粕混合日粮作加性效应检验 ,证明玉米、豆粕中胆碱生物学效价可加性良好

| Abstract: | Growth assays were conducted for one week with broilers at the age of 8 to 14 days,standard curve and slope-ratio techniques were used to evaluate bioavailability of choline in corn or soybean meal.According to a single factorial design,160 commerical Avian broilers of 8-days-old were randomly divided into 10 groups,4 replicates,4 chicks of each .A choline response curve was generated using 0,300,600 and 900mg/kg originated from crystalline choline chloride added to corn-starch-casein diets.Bioavailability of choline in corn or soybean meal was evaluated by 57.47% and 45.97%,respectively,with two corn-casein diets (corn accounts for 42.21% or 72.24%) and two soybean meal-casein diets(soybean meal 16.50% or 24.83%).Two corn-soybean meal diets was used to test the additive effect,the result was satisfactory. |
