This paper represents the growth and productive performances of introduced Corriedale from New Zealand in Weining county of Guizhou province. 本文报道了贵州省从新西兰引进的考利代羊,在威宁县饲养后的生长发育和生产性能情况。
Six corriedale pregnant sheep were divided into treated group and control group as well as planted jugular vein fistula. 6只考力代妊娠母羊随机分成试验组和对照组。
The test showed that improving winter nutrition could obviously increase the capacity and genetic latent energy of crossed Romanov and crossed corriedale. 试验表明，改善越冬营养，可显著地提高罗杂和考杂的生产性能和遗传潜力的发挥。
Four Corriedale sheep fitted with rumen cannula and T shaped duodenum cannula were used to detemine the degradability of diet RNA in rumen by in sacco and in vivo under different diet level. 利用 4只装有瘤胃瘘管和十二指肠 T型瘘管的考力代绵羊 ,饲喂不同粗精比的饲料 ,采用 in sacco和 in vivo法测定了瘤胃饲料 RNA降解率 ,同时利用微生物体固有的 RNA为标记物 ,对瘤胃内未降解的饲料 RNA量换算成瘤胃微生物合成量的影响进行了研究。
Data set of 1261 records of litter size, lamb survival, fertility, pregnancy maintenance and prolificacy from 668 Corriedale ewes and 1188 birth weight records of lambs were used to estimate genetic parameters. 本研究利用668 只考力代母羊的产羔数、活羔数、受精力、妊娠维持和多胎性五个繁殖性状的1261 个记录和1188 只考力代羔羊的初生重记录。
The Genetic Analysis on Reproductive Traits in Corriedale Sheep 考力代绵羊繁殖性状的遗传分析
