新型节能猪舍与传统猪舍环境对断奶仔猪生产性能的比较

Comparison of performance between new energy saving pig house and traditional pig house for weaned piglets

本研究旨在通过测定夏季相同时间段内新型节能猪舍与传统猪舍的环境参数,以及对猪生产性能的影响,为改善养殖环境提供参考。结果表明,在12:00时,新型节能猪舍舍内温度显著低于传统猪舍及外部环境温度(P<0.05),两个类型猪舍舍内湿度显著高于外部环境湿度(P<0.05);在12:00新型节能猪舍CO2浓度显著低于传统猪舍(P<0.05);在8:00、12:00和18:00传统猪舍内氨气浓度都显著高于新型节能猪舍(P<0.05);在12:00新型节能猪舍内部风速显著高于传统猪舍内部以及外部环境风速(P<0.05)。在仔猪生长性能方面,平均日增重、饲料/增重比,节能猪舍比传统猪舍分别提高了6.18%、6.20%(P<0.05)。所以,新型节能猪舍在节约能源的基础上能够在一定程度上改善猪舍内的环境。

The present study was aimed to measure the environment parameters in the new energy saving pig house（ NPH） and traditional pig house（ TPH） during the same summer period and compare their production performances of piglets. The results indicated that the pig house temperature in NPH was significantly lower than that of TPH and outside house（ P0. 05）. The house humidity in these two kinds of houses was higher than that of outside house. House concentrations of CO2 in NPH at 12： 00 were significantly lower than that in TPH. The house concentrations of ammonia gas in NPH at 8： 00,12： 00 and 18： 00 were all lower than that in TPH. Internal air velocity in NPH at12： 00 was higher than that in TPH and outside house. In addition,daily gain,feed/gain ratios in NPH were improved 6. 18% and 6. 20%（ P0. 05）. Together,NPH improved the house environment.
