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.展开更多

Constructing cladogTam of black goat and Guizhou local goat with molecular biological technique, we found some functional genes related to reproduction and growth of black goat, such as FSHR, LHβ, GDF9, MSTN, POU1F1, GFI1B, etc. In view of the genetic relations between Guizhou black goat and other local goats, we reviewed the research status and progress of gene polymorphism of FSHR, LHβ,GDF9, MSTN, POU1F1, GFI1B, and prospected the research field of molecular properties of the breed resource.展开更多
