Cultivation method of novel hybrid line of Qianbei pock-marked goat and Nanjiang yellow goat

Abstract

The invention discloses a cultivation method of a novel hybrid line of Qianbei pock-marked goat and Nanjiang yellow goat. By hybridizing Qianbei pock-marked goat and Nanjiang yellow goat, meat performance and yield of hybrid offspring are increased; by further introducing Qianbei pock-marked goat different from hybrid female parents, meat quality is improved; a target line of Nan-Qian goat is acquired by fixed cross-mating of the Nan-Qian hybrids, and the novel line obtained has good meat performance, high meat yield and fast growth and development gene of Nanjiang yellow goat, and the local feature genes of Qianbei pock-marked goat. Therefore, the novel line has improved features of low meat yield and low growth and development speed in Qianbei pock-marked goat, has improved meat performance and increased growth and development speed, provides fine, delicious and juicy meat and ensures economic and feeding values.
