层叠式立体笼养肉鸡舍秋冬季节环境参数研究
Study on Environmental Quality Parameters in Broiler House with Three-overlap Cages in Winter and Autumn
摘要
Abstract
The study was conducted to detect the indoor environmental quality parameters of broiler house with three-overlap cages and analyze the differences in winter and autumn.In the process of feeding,the same farming house in the same farm was chosen to carry out the test. The indoor ambient temperature,humidity and the air quality were determined in chicken house in different seasons.The measure points were distributed in 4 different positions in the house. The experiment period was from 3 to 6 weeks of broilers.The results showed that there was no significant difference in the ambient temperature between autumn and winter during experimental period (P >0.05).The ambient temperature in the house in winter was slightly higher than in autumn.The humidity in autumn was significantly higher than that in winter (P <0.05 ).The temperature and humidity in two seasons could meet the requirements of broiler growth.There was no significant difference in ammonia concentration between autumn and winter,while ammo-nia level in winter was slightly higher than that in autumn.The carbon dioxide in the house was significantly higher in winter than that in autumn (P <0.05).The total number of airborne bac-teria in winter was significantly higher than that in autumn (P <0.05).The indoor temperature kept constant in autumn and winter seasons in closed poultry house.In winter,the humidity was reduced,the carbon dioxide concentration was increased,and the total number of bacteria in the air was increased.So,the ventilation should increase at the same time of heating in winter.关键词
