摘要
通过对威宁种羊场、毕节马干山牧垦场和盘县坡上牧场等主要育种场内培育中贵的州半细毛羊现有水平的分析,并分别与贵州半细毛羊育种指标和全国考力代理想型羊鉴定标准间进行比较的结果,说明其主要生产性能和羊毛品质大部分场都已超过或达到了前者(育种指标)的要求,而与后者(鉴定标准)间仍存在一定差距。但从责州牧草种籽繁殖场利用人工草地试养绵羊的效果及其与上述育种指标和鉴定标准间比较的结果来看,不仅大大超过了省内育种指标,而且仅除成年种公羊体重一项较低外,其它各项也都超过了全国鉴定标准的要求。说明培育中的贵州半细毛羊种性并不低,改善营养条件乃是迅速提高其生产性能和羊毛品质的关键。据此,本文探讨并提出了如何进一步开展贵州半细毛羊培育工作的四条意见。
Through the research and analysis of Guizhou Semifine Wool Sheep in breeding in the main breeding farms in Guizhou Province included Weiling Stud Sheep Farm, Maganshan Animal Reclamation Farm of Bijie and Poshang Animal Farm of Panxian etc., it is shown that the major productivities and wool qualities have been reached or surpassed the Breeding Targets of Guizhou Semifine Wool Sheep in the most farms, but still have some gaps as compared with the Standard of Judging of Corriedale (ideal type) in China. However, as a result of sheep rearing on the artificial grassland in Guizhou Grass Seeds Farm, it made us to Know the major productivities and wool qualities of Guizhou Semifine wool Sheep in breeding have not only been exceeded the Breeding Targets greatly, but did the Standard of Judging (except the lower live weight of ram only).That is to say, the breed character of Guizhou Semifine Wool Sheep in breeding is good. The Key of the question is to ensure a full of enough nutrient matters and improve sheep's nutritive conditions.Therefore, four specific proposals with regard to further carrying out the breeding work of Guizhou Semifine Wool Sheep were put forward in this paper.
