摘要
通过测定环境温度、湿度、有害气体含量及育肥鲁西黑头肉羊的经济效益,比较了组合式羊舍和传统密闭式羊舍的保温及育肥效果。结果表明:在常规保温措施条件下,组合式羊舍内平均温度比舍外环境高0.73℃,低温时段舍内最低温度比舍外环境提高1.42℃,舍内饮水基本正常使用,可保证肉羊生产正常进行。但与传统砖混结构密闭式羊舍相比,舍内日均温度低0.70℃,最低温度(-7.83℃)低8.38℃,表明冬季保温效果不及传统密闭舍。组合式羊舍内CO2平均含量比密闭式羊舍低20.87%,NH3、H2S未检出。利用中等营养水平颗粒料育肥鲁西黑头肉羊,组合式羊舍肉羊平均日增重比密闭式羊舍提高14.76%,料重比(6.40∶1)降低6.30%,扣除饲料费后只均收入比密闭舍增加14.17元,育肥肉羊效果好于传统密闭舍。
The warm-keeping and fattening effect were compared between combined type and traditional closed cots.The temperature,humidity,harmful gas content and fattening economic profits were determined.The results indicated that in normal insulation measure conditions,the average temperature of combined type sheep cot was 0.73℃ higher than that of outside; in low-temperature period,indoor temperature was 1.42℃higher than outside,and the drinking water equipment could be in normal operation,so the mutton sheep production could be favorably proceeded.But compared to the traditional closed cot with brick-concrete structure,the average indoor temperature of combined type sheep cot was 0.70℃ lower,and the lowest indoor temperature（-7.83℃） was also 8.38℃ lower.This indicated that the insulation effect of combined type sheep cot was poorer than that of traditional closed cot in winter.The average content of CO2 in combined type sheep cot was 20.87% lower than that of traditional closed cot,and NH3 and H2S were not detected out.To fatten Luxi Black Head mutton sheep with medium nutritional level granule feed in combined type sheep cot,the average daily gain increased by 14.76%,the ratio of feed to gain decreased by 6.30%,and the income（deducting feed cost） per head was 14.17 Yuan more compared to those in traditional closed cot,so it had betterfatten effect on mutton sheep.
