摘　　要：为了了解贵州黑马羊生长发育特点，为羔羊培育、肉羊育肥、草场监测、饲养管理提供参考。采用实际观察、试验测定和横、纵向比较等方法对黑马羊的生长发育、产肉性能进行分析。结果表明：贵州黑马羊6月龄公、母羊体重为（18．46±3．29）kg和（17．35±3．23）kg，均显著高于贵州黑山羊（P〈0．05）；周岁公、母羊体重为（29．39±5．51）地和（24．53±5．67）kg，成年公、母羊体重为（40．08±7．73）kg和（34．90±6．56）kg，周岁和成年公、母羊体重均极显著高于贵州黑山羊（尺0．01）。周岁公羊、成年羯羊屠宰率为48．50％、51．61％。公、母羊生长速度0～3月龄最快，日增重为129．56、126．33g；0～6月龄次之，日增重为88．12、84．59g；其他月龄段逐渐下降。已探索出贵州黑马羊的生长发育规律，生长速度胜过贵州黑山羊，且有其特有的外表特征、遗传性稳定，有必要加快新品种的培育。In order to understand the growth and development characteristics of Guizhou Black Horse Goat and provide useful information for rearing lambs, meat goat fatten, grassland monitoring, feeding and management. The growing development and meat performance was analyzed by the actual observation, experiment measurement, transverse and longitudinal comparison methods. The results showed that the bodyweight of 6-month-old male and ewe Guizhou Black Horse Goat was （18.46±3.29） kg and （17.35±3.23） kg, respective, significantly higher than the Guizhou Black Goat （P〈0.05）. The bodyweight of yearling ram and yearling does was respectively （29.39±5.51） kg, （24.53±5.67） kg. Adult ram and adult does weight was （40.08±7.73） kg and （34.90 ±6.56） kg, respectively, significantly higher than the Guizhou Black Goat （P〈0.01）. The dressing percentage of yearling ram and adult wether was 48.50% and 51.61%. The growth rate was best in 0-3 months of age, and which daily gain was 129.56, 126.33 g respective on ram and does. The daily gain was of 0-6 months-old ram and does was 88.12 and 84.59 g, and other month declined gradually. The growth and development law of Guizhou Black Horse Goat has been explored. Its growth speed was better than Guizhou Black Goat. Guizhou Black Horse Goat has its unique physical characteristics, genetic stability, so it was necessary to speed up the breeding progress.
