饲粮铁水平对妊娠母猪繁殖性能和生化参数的影响

30头妊娠母猪随机分为3组,研究了饲粮不同铁水平对其繁殖性能的影响。结果表明,饲粮铁水平200mg/kg组和300mg/kg组与100mg/kg组相比,妊娠母猪90d血清孕酮水平、所生仔猪初生重、仔猪（生后不补铁）断奶重、新生仔猪血红蛋白量和红细胞数都有不同程度的提高;母猪血清含量和仔猪肝脏铁含量也有不同程度的提高。上述提示,适度提高母猪饲粮铁水平能改善母猪的繁殖性能和预防仔猪贫血。

Effects of Various Levels of Iron on the Reproductive Performance and Biochemical Parameters of Gestation Sow

Thirty sows were randomly divided into three groups to study the effects of various levels of iron on the reproductive performance of sow.Compared with 100 mg/kg iron,200 mg/kg iron and 300 mg/kg iron increased the progesterone level of gestation sow(90 d),piglets born weight,piglets weaning weight(no extra iron provided),Hb value and red cell number of piglets.Additionally,the content of sows serum iron and piglets liver iron were increased.The results showed that the supplement of iron in gestation sow diet can improve the reproductive performance of sow and prevent the occurrence of piglet anemia.
