Analysis on Phenotype of Fat Tail Traits of Tan Sheep
摘要
Abstract
In order to obtain the tail traits of fat-tailed sheep,the typical production areas of Tan sheep were selected for investigation and experimental observation analysis.The tail shape characteristics of Tan sheep was summarized by measuring their tail size,weight and tail bone characteristics.The results showed the tail types of Tan sheep include disc tail,wedge tail and triangle tail.The number of the caudal vertebrae ranges from 17 to 21.According to the integrity of it,the caudal vertebrae of Tan sheep falls into four categories.The transverse process,spinous process,vertebral arch and intervertebral foramen of the first type are complete.The transverse process of the second type is complete,and the spinous process,vertebral arch and intervertebral foramen are degenerated.The transverse process,spinous process,verte-bral arch and intervertebral foramen of the third type are degenerated.And the vertebra of fourth type is fused,with no joint capsule.There is a strong phenotypic correlation between tail weight and tail thick-ness,and tail fat rate and tail weight and tail fat weight of Tan sheep.The optimal regression equation be-tween tail weight and tail length and tail thickness was established as follows:y=-2.237+0.401x3+0.041x1(R2=0.634,P＜0.01).关键词
