摘要
为了研究微量元素硒水平对獭兔繁殖性能的影响。试验以50只成年獭兔作为研究对象,随机分成五个组,即在每千克饲料中分别添加0 mg、0.09 mg、0.18 mg、0.36 mg、0.72 mg硒,与对照组(0 mg/kg)比较,结果表明每千克饲料中添加0.18 mg的硒对獭兔的繁殖性能影响显著,其中獭兔的受胎率、产仔数及仔兔初生重均较对照组有明显的促进作用,分别较对照组增加3.33%、13.32%、8.7%。
The object of this paper was to study the effects of trace element Se levels on rex rabbits reproduction.The rabbits were divided into five groups,different Se amounts were added to diets,including 0 mg,0.09 mg,0.18 mg,0.36 mg,0.72 mg.The results demonstrated that 0.18g Se/kg influenced rex rabbits reproduction significantly,which can accelerate conception rate,litter size,birth weight of rex rabbits and increased by 3.33%,13.32% and 8.7% compared to control group respectively.
