  • Online:2014-04-29 Published:2016-11-29

摘要: 摘要:目的 裸小鼠是免疫缺陷动物,饲料硬度对其采食性能及生长影响较大。研究和生产适合裸小鼠采食、硬度适宜并可提高利用率的颗粒饲料,以满足其正常生长。 方法 spf 级10 周龄BALB/c 裸鼠240 只,雌雄各半,随机分为实验Ⅰ组、实验Ⅱ组、实验Ⅲ组、实验Ⅳ、实验Ⅴ和实验Ⅵ组。 实验Ⅰ-Ⅵ分别给予硬度为83.3N、96.0N、112.7N、132.3N、149.0N和181.3N的颗粒饲料,观察不同饲料硬度对裸鼠体质量增加的效果。 结果 各实验组动 物生长情况显示,83.3N、96.0N、112.7N等3 个实验组裸小鼠的体质量增加明显;随着饲料,硬度增加,裸小鼠体质量增加量呈下降趋势。 结论 饲料硬度控制在108-137N 范围BALB/c裸小鼠生长性能良好,还可提高裸小鼠对饲料的利用率。

Abstract: Abstract: Objective To study the effect of grain feed hardness on the growth performance of BALB/c SPF nude Mice. Method 240 10-week-old SPF BALB/c nude mice were randomly divided into experiment GroupI,II,III,IV,V,and VI, and were Feeded by different hardness feed with 83.3N,96.0N,112.7N,132.3N,149.0N,And181.3N, respectively. The effect of feed hardness on the growth performance of BALB/c SPF Nude mice were observed. Result The Body weight of nude mice in experiment grup I,II and III increased significantly. However, as the particle hardness increase, the increase in body weight of nude mice was decrease. Conclusion The feed hardness is controlled in the 108-137N,the growth performance of BALA/c SPF nude mice is good. And the feed utilization is improved.
