摘要
每头母猪每年提供的健康的断奶活仔猪数决定了养猪生产的效益,母猪妊娠和泌乳期日粮中添加鱼油能够改变母体繁殖组织或者胚胎/胎儿组织中的脂肪酸组成,提高窝产仔猪数,促进哺乳期仔猪生长性能,提高母体和后代的健康状况。因此在妊娠和泌乳母猪日粮中添加1%～2%的鱼油能够提高母猪的繁殖性能。
The number of the healthy weaning piglets provided per sow per year is a determinant for profits available in swine production. Maternal diets supplementing with fish oil could change the fatty acid profile of the reproductive tissues, embryo and fetal tissues, and was observed to play a critical role in improving litter size of farrowing, enhancing the growth performance of suckling piglets and promoting the health status of sows and neonatal piglets. In conclusion, it is necessary to fortify 1%-2% fish oil in the maternal diet during gestation and lactation to enhance the reproductive performance of the sow.
