摘要
选择年龄、体重相近的健康成年经同期发情处理后发情的辽宁绒山羊母羊50只,随机分为5组,其中基础日粮组为对照组,在基础日粮中分别添加0.5 mg/kgDM和1.0 mg/kg DM的亚硒酸钠或蛋氨酸硒作为4个试验组。结果表明:妊娠30d,日粮中分别添加0.5mg/kgDM蛋氨酸硒、1.0mg/kg DM的亚硒酸钠和蛋氨酸硒显著提高了血清FSH含量;妊娠前期日粮添加硒显著提高了血清P4和E2含量,有利于妊娠。从总体效果看,蛋氨酸硒组优于亚硒酸钠组。
This study was conducted to investigate the effect of selenium on reproductive hormones in serum of early pregnantdoes. Fifty healthy cashmere does in oestrus with similar body weight were divided into 5 groups randomly,each group with 10 does. One group were fed on a basal diet, the other four groups were fed on a basal diet complemented with0.5,1.0 mg/kg DM methionine selenium or sodium selenite respectively. The results showed： ①Compared with control group,there was a significant increase in serum FSH content of groups with 0.5,1.0 sodium selenite supplementation; ②Supplemented Se in diet increased P4 and in early pregnancy, and would help maintain the pregnancy. mg/kg DM methionine selenium or 1.0 E2 concentration in serum dramatically mg/kg DM （P〈0.05）
