Study on New Line Breeding of Daiyun Goat
摘要
Abstract
In this study,the production performance of Daiyun goat for four generations were researched. Results showed that the lambing rates of first-born and multiparous goats in all generations ranged from 125.3% to 137.4% and 191.4% to 204.7%, respectively; the lambing rates of the second, third ,fourth generation were significantly higher than that of the first generation(P < 0.05);the lambing rate of each generation was all improved compared with the previous generation; the lambing rates of first-born(137.4%)and multiparous(204.7%)goats in the fourth generation were the highest,increased by 25.8% and 9.06%, respectively,compared with the first generation;the surviving rates of first-born(96.9%)and multiparous(97.9%)goats in 2-month-old in the fourth generation increased by 7.43% and 19.10% than those(90.2% and 82.2%)of the first generation, respectively; the genetic progress of the third and fourth generation tended to be slowed,but the goat population of core group increased by 98.5% and 150.8% over the first generation,respectively;there were no significant difference(P > 0.05) in the body weights and body measures among the generations关键词
