地顶孢霉培养物对肉仔鸡增重的影响

Effects of the Culture of Acrermonium Terricola on Weight Gain in Broiler Chickens

摘要:

为了探讨地顶孢霉培养物（culture of Acrermonium Terricola，ATC）对白羽肉仔鸡增重的影响，试验选用200只新生肉仔鸡，随机分成2组。对照组饲喂基础日粮，地顶孢霉组在基础日粮中添加0.20%的ATC，试验期为42 d，期间每周记录体重，分析平均日增重，并统计试验期各组耗料量，计算增重带来的养殖效益。结果表明：试验期内，与对照组相比地顶孢霉组平均体重显著提高13.23%（P<0.01）；平均日增重显著提高13.53%（P<0.01）。地顶孢霉组盈利比对照组提高14.06%。说明饲料中添加ATC可以显著提高肉仔鸡的平均日增重，增加养殖效益，有利于禽类动物的无抗养殖。

Abstract:

The purpose of this study was to investigate the effect of culture of Acerermonium Terricola (ATC) on weight gain of whitefeathered broiler chickens. In this experiment, 200 1-day-old broiler chickens were randomly divided into 2 groups. The control group was fed the basal diet, and the Acerermonium Terricola group was fed with 0.20% ATC in the basal diet. The test period was 42 days. During this period, we recorded the body weight every week, analyzed the average daily gain, and counted the feed consumption of each group during the test period, and calculated the breeding benefits brought by the gain. The results showed that during the test period, compared with the control group, the average body weight of the Acerermonium Terricola group was significantly increased by 13.23% (P<0.01); the average daily weight gain was significantly increased by 13.53% (P<0.01). The profit of Acerermonium Terricola group was 14.06% higher than that of the control group. This shows that adding ATC in the feed can significantly increase the average daily gain of broilers. This increases breeding benefits and is beneficial to the antibioticfree and breeding of poultry animals.
