摘要
以肉鸡为研究对象,采用单因子随机分组设计,将300羽1日龄肉鸡随机分成4组,每组5个重复,每重复15只(86,79)。组Ⅰ为基础饲料+1%组方1、组Ⅱ为基础饲料+1%组方2、组Ⅲ为基础饲料+1%组方3、组Ⅳ为基础饲料+泰乐菌素为对照组。结果表明:复方中草药添加剂各组的日增重在前期与抗生素组差异不显著(P〉0.05),但中草药添加剂组对日增重的影响呈上升趋势,尤以组Ⅱ最明显,在36~42日龄,组Ⅱ的日增重高于抗生素组,且差异显著(P〈0.05)。在物质代谢方面,组方1在促进干物质代谢率、粗脂肪代谢率、粗灰分代谢率与对照组无显著差异,组方2在促进粗蛋白代谢率的作用略优于对照组,组方3在促进干物质代谢率、粗脂肪代谢率与对照组无差异显著。在肉鸡的生产中,合理的复方中草药可以替代抗生素添加剂。
The test adopted random control design,300 broilers were randomly divided into basal diet + 1% formula 1 ( group Ⅰ ) , basal diet + 1% formula 2 ( group Ⅱ), basal diet + 1% formula 3 ( group Ⅲ) and basal diet + Tylosin (control) ,5 replicates in each group and 15 chickens in each replicate( 8 males and 7 females). The results showed that the average daily gains (ADG)of 15 ~ 35 days of age were not significantly different in group Ⅰ ' Ⅱ ' Ⅲ' and control(P 〉0.05). However there was an uptrend in the average daily gains (ADG) of 15 ~ 35 days of age in the experimental group. The daily weight gain of Group Ⅱ was significantly higher than that of the control ( P 〈 0.05 ) in 36 ~ 42 days of age. The metabolic rates of nutrients were not significantly different in each group ( P 〉 0.05 ). The mtabolic rate of crude protein of the two trial groups was slightly better than that of the control group. Formula 3 showed no significant difference in dry matter metabolic rate, fat metabolic rate and phosphorus metabolic rate ( P 〉 0.05). Chinese herbal medicine can replace antibiotic for feed additives in the poultry industry.
