摘要
本文主要内容是以自然选择方法为前提,对新西兰罗姆尼羊初次引入江西清江后,使羊体常年保持中等以上营养水平.通过连续两年的观察结果是:在夏秋高温期未发生中暑死亡现象;在霉雨季节未发现腐蹄病.母羊发情率为100%,受胎率70%,母羊产羔率114.3%.剪毛量公羊5.4公斤,母羊3.8公斤,毛长公羊为16.9cm,母羊14.7cm.通过实地观察和测定,可初步认为罗姆尼羊对高温环境有较强耐力.
Based on the natural selection and moderate nutritive level,the adaptabilityof New Zealand Rommney was observed for two years after the sheep were firs-tly introduced into Qingjiang county,Jiangxi Province.There were no cases of deathcaused by heatstroke in the summer-autumn high air temperature stage,neithercases of rotten-hoof disease in the rainy season.The oestrus rate of ewe was1000%;The conception rate was 70%;The rate of lambing was 114.%.The sh-earing yields were 5.4kg/ram and 3.8kg/ewe.The average wool length of ramand ewe were 16.9cm and 14.7cm respectively.Those results showed that theheat resistance of New Zealand Rommney was quite good.
