摘要
选取了10个养兔场(户)5 000只繁殖母獭兔做试验,每千克饲料中添加0.18mg硒,与2007年和2008年饲料中未添加硒的繁殖性能进行比较。结果表明:饲料中添加硒后,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7.68g,平均泌乳力提高了174.46g,断奶窝重提高了258.11g,断奶个体重提高了41.0g,断奶成活率提高了10.55%。
5 000 breeding female Rex rabbits were selected from 10 rabbit farms,raised with selenium 0.18mg / kg feed,and compared the reproductive performances with those without adding selenium in 2007 and 2008.The results showed that the fertility rate of test rabbits increased 5.95%,average litter size improved 1.5,average litter born weight 32.86g,average newborn individual weight 7.68g,average milk ability 174.46g,weaning litter weight 258.11g,weaning individual weight 41.0g,and weaning survival rate 10.55%.
