【摘要】：为了对獭兔被毛密度的三种测量方法进行比较,试验选取10只雌雄各半的5~6月龄的獭兔,以背部和体侧部作为取样部位,分别采用直接计数法、毛样重量比例法和毛囊显微计数法三种方法对獭兔被毛密度进行测量,并用直接计数法和毛样重量比例法测量粗毛率,并综合比较和分析三种方法的测量结果是否存在差异。结果表明:獭兔背部的被毛密度,直接计数法测量结果为(20 075±1 127)根/cm~2,毛囊显微计数法测量结果为(19 872±1 490)根/cm~2,二者无显著差异(P0.05);毛样重量比例法测量结果为(22 048±2 727)根/cm~2,与直接计数法和毛囊显微计数法有显著差异(P0.05)。獭兔体侧部的被毛密度,直接计数法测量结果为(20 404±1 261)根/cm~2,毛囊显微计数法测量结果为(19 621±1 047)根/cm~2,两者无显著差异(P0.05);毛样重量比例法测量结果为(22 432±2 769)根/cm~2,与直接计数法和毛囊显微计数法有显著差异(P0.05)。同时,背部和体侧部的被毛密度由同一种方法测量结果均无显著差异(P0.05)。对獭兔背部粗毛率的测量,直接计数法和毛样重量比例法的所得结果分别为(3.10±0.42)%和(6.19±1.10)%,有显著差异(P0.05);体侧部的粗毛率,直接计数法和毛样重量比例法检测结果分别为(3.70±0.66)%和(5.93±0.95)%,有显著差异(P0.05)。说明三种测量方法得到的结果有一定的差异,推荐使用直接计数法和毛囊显微计数法测量獭兔被毛密度,使用直接计数法测量粗毛率。
[Abstract]:In order to compare the three methods of measuring the hair density of Rex rabbits, 10 Rex rabbits of 5 and 6 months old, half of each sex, were selected, the back and the side of the rex rabbits were taken as the sampling sites, and the direct counting method was used respectively. Wool weight ratio method and hair follicle microcounting method were used to measure the wool density of Rex rabbits. The gross wool percentage was measured by direct counting method and wool weight ratio method. The results of the three methods were compared and analyzed comprehensively. The results showed that the hair density in the back of Rex rabbits was (20 075 卤1 127) root / cm~2, hair follicle microcount method and there was no significant difference between them (P0.05). The results of wool weight ratio method were (22 048 卤2 727) root / cm~2, which were significantly different from those of direct counting method and hair follicle counting method (P0.05). The hair density of the lateral part of Rex rabbits was (20 404 卤1 261) root / cm~2, hair follicle microcount method. There was no significant difference between the two groups (P0.05). The result of wool weight ratio method was (22 432 卤2 769) root / cm~2, which was significantly different from that of direct counting method and hair follicle counting method (P0.05). At the same time, there was no significant difference in the density of coat between the back and the lateral part by the same method (P0.05). The results obtained by direct counting method and wool weight ratio method were (3.10 卤0.42)% and (6.19 卤1.10)%, respectively (P0.05). The results of gross hair rate, direct counting and wool weight ratio were (3.70 卤0.66)% and (5.93 卤0.95)%, respectively (P0.05). It is suggested that the direct counting method and hair follicle microcounting method should be used to measure the hair density of Rex rabbits, and the direct counting method to measure the coarse hair rate.
