外界温度对标准化肉鸡舍内环境的影响
|
摘要
本试验旨在研究外界环境温度对标准化肉鸡舍内环境的影响。试验结果表明:①1d外界温度与舍内温度为低度正相关,7、14、21和28d均为显著正相关,35d为不相关;②外界温度与舍内湿度均为低度相关或无直线相关;③1d外界温度与舍内氨气浓度为低度负相关,7d为显著负相关,14、21,28和35d均为高度负相关;④1d外界温度与舍内二氧化碳浓度为低度正相关,7、14、21、28和35d均为高度负相关。以上结果表明,外界温度对标准化鸡舍内温度,氨气和二氧化碳浓度影响较大。
This research intend to investigate the effect of the outside temperature on the environment in standardization broiler house. The results showed as follows: 1)The outside temperature was low positive correlation with the temperature in broiler house in the 1st day age, the 7th, 14th, 21th and 28th days were significant positive correlation, and the 35th days was no correlation; 2)The outside temperature was low correlation or no correlation with the humidity in broiler house; 3)The outside temperature was low negative correlation with the concentrations of atmospheric ammonia in broiler house in the 1st day age,the 7th days was significant negative correlation, the 14th, 21th, 28th and 35th days were highly negative correlation; 4)The outside temperature was low positive correlation with the concentrations of carbon dioxide in broiler house in the 1st day age, the 7th, 14th, 21th, 28th and 35th days were highly negative correlation. The results indicated that the outside temperature has great effect on the temperature, the concentrations of atmospheric ammonia and carbon dioxide in standardization broiler house.
