| 摘 要： | 通过连续8周在断奶幼兔的日粮中添加富硒或富硒钴苜蓿草粉的试验,研究硒钴两种微量元素对幼兔生长以及饲料转化率的影响。结果表明,在幼兔断奶后的2周,在日粮中添加富硒或者富硒钴苜蓿草粉是非常必要的,幼兔平均绝对日增重较对照分别提高46.1%和47.3%,平均相对日增重较对照分别提高24.3%和33.5%。富硒或者富硒钴苜蓿草粉不能连续使用2周以上,否则会影响到幼兔生长,应该间隔3到4周后再添加,会提高其利用价值。在整个试验过程中,添加富硒或者富硒钴苜蓿草粉均能降低料肉比,提高饲料转化率,添加10%和15%的富硒苜蓿草粉分别能使料肉比降低0.6%和3.1%,而添加同量的富硒钴苜蓿草粉分别能使料肉比降低4.7%和6.6%。

| Abstract: | This paper made a comparative trials of two kinds of alfalfa meals(one abundant in Selenium and another abundant in Selenium and cobalt) when applied to the diet weaning rabbit for successive 8 weeks.The aim of the experiments was to study the influence of the Selenium and cobalt on the growth and feed conversion efficiency of weaning rabbit.The results showed in first two weeks just after weaning it is vital important to add two above-mentioned alfalfa meals to diet which can enhance daily weight gain for ... |
