畜禽遗传资源状况数据库(绵羊)

本数据集由国家农业科学数据中心（动物科学和动物医学）建设。
我国养羊生产逐步由毛用向肉毛兼用和肉用方向发展，采用的杂交组合方式很多，多以外血种公羊作为第一父本或终端父本，以国内地方品种羊作母本，以获得较好的杂种肉羊。本数据集提供了我国50个绵羊品种的产地（或分布）、调查数量、主要特性以及图片信息，其中包括地方品种31个、培育品种9个和引入品种10个。数据信息会根据品种调查的进展及时更新。

This dataset was developed by the National Agricultural Science Data Center (Animal Science and Veterinary Medicine). China's sheep farming production is gradually shifting from wool-focused to dual-purpose (meat and wool) and meat-focused production. A wide variety of crossbreeding combinations are adopted, with exotic rams mostly used as the first paternal parent or terminal sire, and local domestic sheep breeds as dams to produce high-quality crossbred meat sheep. This dataset provides information on the origin (or distribution), survey sample size, core characteristics, and images of 50 sheep breeds in China, including 31 local breeds, 9 selectively developed breeds, and 10 introduced breeds. The dataset will be updated in a timely manner alongside the progress of breed surveys.
