冬季肉鸡不同饲养模式下环境指标的监测与生产性能分析
Environmental Indicator Monitoring and Production Performance Analysis of Broilers under Different Feeding Patterns in Winter
摘要
Abstract
In order to understand the differences of environmental indicators and production performance among the three representative feeding modes (thickness pad material feeding,net-rearing and three-layer cage) in Shandong Province,the carbon dioxide,ammonia,wind speed,light,humidity and temperature of the three chicken houses were monitored on the 10th,25th and 35th day respectively in this experiment.The differences of the main environmental indicators between different feeding modes were compared,meanwhile,the production performance were also compared in feed conversion ratio and survival rate.The results showed that the environmental indicators such as temperature,humidity,carbon dioxide and ammonia gas were different between three feeding modes.The concentration of harmful gases increased gradually and the temperature decreased gradually from the 10th day to the 35th day.The comparison results of three feeding modes at the same day age showed that the concentrations of harmful gases such as carbon dioxide and ammonia gas did not change regularly,and the ammonia concentration of net-rearing was the highest while that of the layer cage was the lowest at the 25th and 35th day.The three-layer cage mode had the best feed conversion ratio,survival rate and slaughter weight.In a word,the concentrations of harmful gases at different day ages were relatively lower and the production performance was the best in layer cage.关键词
