摘要
龙陵黄山羊是云南省保山市龙陵县特有的遗传资源,其体重和各项体尺指标的持续观测对保种和选育具有重要意义。该研究主要以2019—2022年龙陵县黄山羊核心种羊有限责任公司乌木山养殖基地内的龙陵黄山羊为研究对象。经过对产羔数、体重和各项体尺指标的统计分析发现,母羊产双羔率较2019年有所下降。母羊体重和胸围以及公羊胸围、体高和管围都呈逐年递减的趋势,且母羊体重和胸围均极显著下降(P<0.01)。公羊的体重、体高、体长、胸围、胸宽和管围指标在2019年均极显著高于2022年(P<0.01)。母羊的体重、体高、体长、胸围和胸深指标在2019年均极显著高于2022年(P<0.01)。基于以上结果,提出龙陵黄山羊选育建议,为龙陵黄山羊保种和品种提纯复壮提供参考。
Longling Yellow goat is a unique genetic resource in Longling County,Baoshan City,Yunnan Province.The continuous observation of its body weight and body size indicators is of great significance for conservation and breeding.This study mainly takes Longling Yellow goat in the Wumushan breeding base of Longling County Yellow Goat Core Breeding Sheep Co.,Ltd.from 2019 to 2022 as the research object.Statistical analysis of littter size as well as body weights and all body size indicators revealed that does was a decrease in twinning rates compared to 2019.The body weight and chest circumference of ewes and the chest circumference,body height and cannon circumference of rams showed a decreasing trend year by year,and the body weight and chest circumference of ewes decreased significantly(P<0.01).The body weight,body height,body length,chest circumference,chest width,and cannon circumference of rams in 2019 were significantly higher than those in 2022(P<0.01).The body weight,body height,body length,chest circumference,and chest depth of ewes in 2019 were significantly higher than those in 2022(P<0.01).Based on the above results,suggestions for the breeding and improvement of Longling yellow goats were put forward,which provided a reference for the conservation variety purification,and rejuvenation of Longling Yellow goats.
