摘要
To culture new breeds of Guizhou Heima goat, establishing open nucleus br^ding system in farm was adopted to develop comprehensive selection index and establish BLUP model to estimate breeding value, so as to guide assortative mating and selection improvement. The results showed that the body weights of yearling ram and ewe in nucleus herd were （29.77± 5.51 ） kg and （25.18 ± 5.67 ） kg, while those of adult ram and adult ewe were （40.08 ± 7.73 ） kg and （ 34.90 ±6.56） kg, respectively; the body weights of yearling ram and ewe in basic herd were （26.59 ±3.68） kg and （24.139 ±4.60） kg, while those of adult ram and adult ewe were （35.33 ± 4.09） kg and （32.16 ± 6.83 ） kg, respectively; the lambing rate was 152.33 % ; the slaughter rate was 48.50%, and the net meat rate was 38.94%. New breeds of Guizhou Heima goat had significantly improved production performance and breed uniformity, with stable genetic performance.
