摘要
为了探讨母猪妊娠早期日粮中添加一定量的甲基吡啶铬、叶酸、维生素E和维生素A对母猪窝产仔数、初生重、仔猪成活率的影响,选用日龄、体况基本一致的长大二元母猪共计56头进行试验。结果表明,在母猪妊娠早期的日粮中添加甲基吡啶铬、叶酸、维生素E、维生素A可显著提高母猪窝产仔数,提高比例平均为29.2%,其中对后备母猪提高比例更大。
In order to expore the effect of nutritional manipulation on pigsow reproductive performance,a certain amount of chromium picolinate,folic acid,VE and VA were added to early basic diet of 56 heads of binary sows.The litter size,birth weight and piglets surviving rate were determined.The results showed that the supplement of chromium picolinate,folic acid,VE and VA in sows' early diet could significantly improve litter size of sows by 29.2%,especially in replacement gilts.
