Abstract
文章旨在研究日粮中添加不同水平三丁酸甘油酯对肉鸡综合性能的影响.本试验将 160 只体重相近、健康无病的 1 日龄肉鸡随机分为 4 组,每组 4 个重复.对照组肉鸡饲喂基础日粮.试验Ⅰ、Ⅱ和Ⅲ组分别在基础日粮中添加 1000、1500、2000 mg/kg三丁酸甘油酯.预饲期 7 d,正试期 42 d.结果表明,与对照组相比,试验组肉鸡的 42日龄体重和平均日增重显著增加(P<0.05),试验Ⅱ、Ⅲ组肉鸡的料重比显著降低(P<0.05),但平均日采食量无显著差异(P>0.05);试验组干物质、粗蛋白质、粗纤维及能量的表观消化率均显著增加(P<0.05);试验组肉鸡血清中总蛋白质含量和高密度脂蛋白含量显著增加(P<0.05),总胆固醇和甘油三酯含量显著降低(P<0.05),各试验组肉鸡血清中低密度脂蛋白含量较对照组无显著差异(P>0.05).总的来讲,日粮中添加三丁酸甘油酯能有效改善肉鸡生长性能,提升养分表观消化率,改善血清生化指标,综合考虑,肉鸡日粮中三丁酸甘油酯的最适添加量为1500 mg/kg.
The influence of ttributyl glycerides on growth performance in broilers were explored.160 healthy and disease-free 1 day old broiler chickens broiler chickens of similar weight were selected for this experiment.The control group of broilers were fed with basic diet.Groups Ⅰ,Ⅱ,and Ⅲ of the experiment were supplemented with 1000 mg/kg,1500 mg/kg,and 2000 mg/kg tributyl glycerol esters in the basic diet,respectively.The pre experimental period is 7 days,and the formal experimental period is 42 days.The research results showed that compared to the control group,the 42 day old body weight and average daily gain of the experimental group broilers significantly increased(P<0.05),while the feed to weight ratio of the experimental Ⅱ and Ⅲ groups broilers significantly decreased(P<0.05),but there was no significant difference in average daily feed intake(P>0.05);The apparent digestibility of dry matter,crude protein,crude fiber,and energy in the experimental group significantly increased(P<0.05),while the apparent digestibility of crude fat showed no significant difference compared to the control group(P>0.05);The total protein content and high-density lipoprotein content in the serum of broiler chickens in the experimental group significantly increased(P<0.05),while the total cholesterol and triglyceride content significantly decreased(P<0.05).However,the low-density lipoprotein content in the serum of broiler chickens in each experimental group showed no significant difference compared to the control group(P>0.05).Overall,adding tributyl glyceride to the diet can effectively improve the growth performance of broilers,enhance their nutrient apparent digestibility,and improve serum biochemical indicators.Overall,it is recommended that the appropriate amount of tributyl glyceride be added to the diet of broilers is 1500 mg/kg.
