摘　　要：文章旨在研究饲粮中添加肌醇对生长獭兔毛囊密度的影响。选取40日龄断奶小兔120只（公母各半）,随机分成4组,每组30只,常规饲养,饲料中分别按0、25、50、75 mg/kg添加肌醇,试验期为3个月。在试验的第30、60、90 d,分别取肩部、腹部、背中部、臀部皮肤,制作石蜡切片,观察计数初级和次级毛囊数量并计算S/P值发育。结果表明,饲粮中添加50 mg/kg肌醇可以显著增加2-4月龄獭兔背中部和臀部次级毛囊密度（P〈0.05）,显著降低2-3月龄背中部和臀部初级毛囊密度（P〈0.05）,对肩部和腹部毛囊密度的影响没有明显规律。饲粮中添加50 mg/kg肌醇能够显著影响2-4月龄獭兔背中部和臀部毛囊密度。The purpose of the experiment was to study the effect of inositol on hair follicle density of growing rex rabbits. 120 rabbits （half of male and female） , about 40 days old, were randomly assigned into 4 groups （control group, experimental group 1, experimental group 2, experimental group 3）, 30 replicates per treatment .The rabbits of 4 groups were fed diets with different inositol addition levels （0, 25, 50, 75 mg/kg respectively）, the experiment lasted 3 months. The skin of shoulder, abdomen, dor- socentral region, hip were collected on 30, 60, 90 d respectively. Paraffin section were made to calcu- late the density of hair follicle and S/P value. The diet added with 50 mg/kg inositol could significant- ly increase the secondary follicle density of skin of dorsocentral region and hip from 2-4 months Rex rabbits （P〈0.05, and significantly decrease the primary follicle density of skin of dorsocentral old re- gion and hip from 2-3 months old rex（P〈0.05）. Addition of 50 mg/kg inositol has no regularly effect on hair follicle density of skin of shoulder, abdomen. It is concluded that the diet added with 50 mg/kg inositol has significantly effect on skin follicle density of dorsocentral region and hip from 2-4 months old rex.
