Embodiment 1

[0050] Example 1 Application of P2P Breeding Technology Mode in Breeding of Short-tailed Gobi Sheep

[0051] 1. Basic group formation and small group breeding

[0052] From April 8th to April 13th, 2016, the tail shape and body weight data of 400 adult Mongolian sheep and 350 lambs bred by Siziwang Banner Sunite Sheep Breeding Co., Ltd. were standardized. Between 3-20cm, with an average of 11.14cm; tail width between 3-19cm, with an average of 11.26cm. Lamb tail length is between 3.5-15cm, with an average of 9.61cm; tail width is between 5.5-15cm, with an average of 9.75cm. According to the measurement, the tail type of Mongolian sheep is divided into three types: large tail, middle tail and small tail: the length and width of adult Mongolian sheep’s tail are respectively greater than 12cm, which is defined as the large tail type, and the length and width are respectively less than 10cm, which is defined as the small tail type. The positioning between 10-12cm is the middle t...

Abstract

The invention provides a group breeding method for mutton sheep, which relates to the technical field of animal breeding. The invention provides a method for group breeding of mutton sheep. The breeding rams and breeding ewes are divided into small groups and paired in groups to obtain a generation of lambs ;Test the performance of offspring and select some of them for paternity identification; Estimate and sort the breeding value of rams and lambs that have a relationship after parentage identification, and select some excellent rams and lambs as the next generation of rams Rams: From the second generation, the rams are rotated among small groups, and new strains can be selected and bred after several generations. The P2P breeding method described in the present invention is suitable for the breed selection of mutton sheep and the original mating species in the new breed breeding process of mutton sheep; it can effectively solve the problem of pedigree file record of the original mating species of mutton sheep; Insemination is less costly.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a group breeding method for mutton sheep. Background technique [0002] In the breeding and production practice of mutton sheep, it is necessary to establish a complete performance measurement and individual selection / pedigree recording system to lay the foundation for subsequent individual selection and comprehensive evaluation. However, due to factors such as grass-roots artificial insemination technology, manpower and production costs, it is difficult to implement accurate individual selection and pedigree registration in mutton sheep production. At the same time, the cost of paternity testing for group selection of mutton sheep is high and the cycle is long, which is not suitable for mutton sheep breeding. Contents of the invention [0003] In order to overcome the defects of high cost and low efficiency of the existing group breeding of mutton sheep, the present i...
