摘要
选用两个批次四川白猪Ⅰ系初产妊娠母猪在日粮DE12.05～12.72MJ／kg，CP12.56％～13.04％营养水平条件下，观察测定其繁殖性能和体重变化，探讨初产母猪在冬季怀孕期适宜的能量需要。结果表明：平均妊娠体重130kg左右的四川白猪Ⅰ系初产母猪冬季怀孕时，妊娠前期（1～84d）日供DE26.51MJ，后期（85d～分娩）日供DE32.31MJ，全期平均日供DE28.00MJ，能够满足妊娠母猪的能量需要。母猪除维持需要外，每1kg妊娠增重耗DE20.91MJ。
The energy requirement were determined through the reproducement and the change of body weight in two batches primiparous pregnancy Sichuan white sows,feeding the diet contained DE (digestive energy) 12.05～12.72MJ／kg and CP 12.56％～13.04％ in winter.The results suggested for the pig (about 130kg average pregnance weight) in winter supply DE 26.51MJ in prophas (1～84 days) and 32.31MJ in anaphase (85days～parturition) daily,or DE 28.00MJ／day during pregnancy averagely can meet the requirement of the pregnance pig. Besides the maintain requirement, the gain during pregnancy consumed DE 20.91MJ／kg.
