迁移式鸡舍对肉鸡生长性能及舍内环境的影响

试验选取880羽21日龄岭南三黄鸡,随机分成2组,每组4个重复。其中对照组在传统的固定鸡舍内饲养,试验组在迁移式鸡舍组内饲养。旨在研究迁移式鸡舍对肉鸡生长性能及空气指标的影响。结果表明:迁移鸡舍组和传统鸡舍组平均日增重分别为28.05 g和27.84 g(P>0.05),饲料增重比分别为3.10和3.13(P>0.05)。在舍内空气环境指标方面,迁移式、传统鸡舍内日平均温度分别为11.22、9.96℃;隔日测定氨气浓度分别平均为2.98、2.70μg/mL,均未超过规定的安全浓度(5～20μg/mL)。因此迁移式鸡舍能够替代传统的固定鸡合并推广。

Effects of the Removable Chicken House on Growth Performance of Broilers and Indoor Environment Parameters

The experiment was conducted with 880 one-day-old Lingnan yellow broilers.All broilers were randomly divided into two groups on 21 days,each with four replications.The broilersin control group were raised in the general fixed chicken house and the treated broilers in the removable chicken house.The effects of the removable chicken house on the growth performance in broilers and indoor environment parameters were studied.The results indicated that the average daily gain was 28.05 g in the removable group and 27.84 g in the control.The feed gain ratio was 3.10 in the former and 3.13 in the latter.The growth performance was better in the removable group than that in the control group while the difference was insignificant.The daily average temperature was 11.22℃inside the removable house and 9.96℃in the fixed one.The concentration of NH_3 was measured every other day.The daily average concentration of NH_3 was 2.98μg/mL in the removable house and 2.70μg/mL in the fixed one,both less than the prescribed safe concentration.In conclusion,the removable house is desirable and can be applied to replace the traditional fixed one.
