【摘要】：本試驗采用環(huán)境監(jiān)測的方法,通過對冬、夏季哺乳仔豬舍和保育舍內(nèi)主要環(huán)境參數(shù)進行監(jiān)測,并對仔豬生產(chǎn)性能進行測定,為改善封閉式豬舍內(nèi)主要環(huán)境參數(shù)提供參考,為仔豬創(chuàng)造適宜的生長環(huán)境提供理論依據(jù)。結(jié)果表明:1夏、冬季哺乳仔豬舍二氧化碳、氨氣和硫化氫的濃度分別為2220mg/m3和4412mg/m3、2.11mg/m3和10.11mg/m3、0.72mg/m3和2.61mg/m3,保育舍內(nèi)二氧化碳、氨氣和硫化氫的濃度分別為659.56mg/m3和4416.00mg/m3、1.55mg/m3和2.51mg/m3、0.42mg/m3和1.53mg/m3。冬季舍內(nèi)有害氣體濃度顯著高于夏季。夏冬兩季哺乳仔豬舍內(nèi)的溫度差異不顯著,分別為25.91℃和24.47℃,保育舍夏冬兩季舍內(nèi)溫度差異極顯著,分別為27.87℃和21.07℃。2夏季哺乳仔豬舍內(nèi)二氧化碳濃度顯著高于保育舍,分別為2220.34mg/m3、659.56mg/m3,冬季兩類型豬舍內(nèi)的二氧化碳濃度變化差異不顯著,哺乳仔豬舍其他有害氣體濃度均顯著高于保育舍,同一季節(jié)哺乳仔豬舍內(nèi)溫度高出保育舍2~3℃。夏季哺乳仔豬舍和保育舍內(nèi)濕度存在極顯著差異,分別為53.35%和50.18%,冬季哺乳仔豬舍和保育舍內(nèi)濕度差異不顯著。3冬、夏季哺乳仔豬舍和保育舍內(nèi)有害氣體濃度最高值均出現(xiàn)在上午6:00,保育舍冬、夏季溫度最高值均出現(xiàn)在中午11:00,哺乳仔豬舍夏季溫度最高值出現(xiàn)在18:00,冬季出現(xiàn)在11:00,夏季哺乳仔豬舍和保育舍的濕度最大值均出現(xiàn)在18:00,冬季均出現(xiàn)在6:00。4舍內(nèi)環(huán)境對仔豬生產(chǎn)性能存在顯著影響,舍內(nèi)環(huán)境較好的豬舍有利于仔豬生產(chǎn)性能的發(fā)揮,能夠顯著提高哺乳仔豬窩斷奶重,提高斷奶仔豬的日采食量和平均日增重。
[Abstract]:The environmental monitoring method was used to monitor the main environmental parameters of breast-feeding piglets and nursery houses in winter and summer, and to determine the performance of piglets. In order to improve the main environmental parameters of closed piglets and provide a theoretical basis for piglets to create a suitable growth environment, the results showed that the carbon dioxide in weaning piglets in winter and in winter. The concentrations of ammonia and hydrogen sulfide were 2220 mg / m3 and 4412 mg / m3, 2.11 mg / m3 and 10.11 mg / m3, respectively. The concentrations of CO2, ammonia and hydrogen sulfide in conservation houses were 659.56 mg / m3 and 4416.00 mg / m3, respectively. 1.55 mg / m3 and 2.51 mg / m3. 0.42 mg / m3 and 1.53 mg / m3. The concentrations of harmful gases in winter were significantly higher than those in summer. There was no significant difference in temperature in piglets in summer and winter. It was 25.91 鈩，
