摘要
为探讨生长育肥猪绝食代谢试验的绝食时间,对3头瘦肉型去势公猪进行了两个体重阶段(40—50公斤)和(65—75公斤)1—6天的绝食代谢测定。前期绝食3天、后期绝食4天,呼吸商、体物质分解量和绝食产热量均达到平稳状态。分别为0.68—0.77、9.42—10.83(克/公斤^(0.75)·天)和80.50—94.17(千卡/公斤^(0.75)·天)。
Results of one to six days of fasting with three barrows of lean type breed showed that the respiration quotient (R.Q.) and the fasting heat production were stable after three days of fasting for 40-50 kg liveweight and after four days |of fasting for 65-75 kg liveweight.
