摘要
2009年,在獭兔日粮中添加0.18 mg/kg硒,与2007、2008年未添加硒的獭兔进行繁殖性能比较,试验结果受胎率提高了5.95%,平均窝产仔数提高了1.5只,初生平均窝重提高了32.86g,初生平均个体重提高了7.68 g,平均泌乳力提高了174.46 g,断奶窝重提高了258.11 g,断奶个体重提高了41.0 g,断奶成活率提高了10.55%。表明了在獭兔的日粮中添加0.18 mg/kg的硒,对繁殖性能的提高极显著(P<0.01)。
In 2009,0.18mg/kg selenium was added to rex rabbit diets,compared to reproductive performance in 2007 and 2008,the results demonstrated that conception rate improved 5.95%,average number of per litter improved 1.5 piglets,average birth weight of litter improved 32.86g,average body weight improved 7.68g,average lactescence improved 174.46g,weanling litter weight improved 258.11g,body weight of weanling pig improved 41.0g,weanling survival rate improved 10.55%.To sum up,adding 0.18mg/kg selenium improved reproductive performance of rex rabbit significantly（P〈0.01）.
