【摘要】 为研究生物发酵式猪舍缓解热应激小气候智能化调控系统效果,选用2个生物发酵式养猪场,比较其对改善猪舍温度、湿度、温湿指数(THI)、氨浓度的效果以及对猪的采食量、日增重、料肉比的影响。结果表明,南方生物发酵式猪舍在夏季采用缓解热应激小气候智能化调控系统可极显著降低猪舍的温度(P<0.01)、TH(IP<0.01)和氨气浓度(P<0.01),可显著提高猪的日增重和饲料转化效率。更多还原

【Abstract】 In this study we chose 2 micro-organism fermentation bed pigsty. The improvement of pigsty temperature, humidity, THI and the effect of body temperature, feed intake, weight daily gain, feed conversion ratio, economic benefits in the fermentation bed pigsty installed with the micro-climate control system were for comparative analysis. The results showed that using the south area micro-climate control system in the fermentation bed pigsty in summer could significantly improve the micro-climate in pigsty, ensured the health of swine, increased the daily gain and feed efficiency.更多还原
