奶山羊良种缺乏是制约我国奶山羊产业高质量发展的“卡脖子”问题。本文介绍了阿尔卑斯奶山羊的外貌特征和生产性能。重点阐述了以阿尔卑斯奶山羊作父本,利用关中奶山羊作母本,采用级近杂交与功能基因选择相结合的现代分子育种新技术,选育适用于集约化生产的优质高产奶山羊新品种,期望有效解决我国奶山羊近交严重,乳房形状、产奶量和乳成分差异大等产业化发展难题,支撑我国奶山羊产业高质量发展。
The lack of improved varieties of the dairy goat is the bottleneck issue that restricts the development of high-quality dairy goat industry in China. The macroscopic features and production performance of the Alpine dairy goat were introduced in this paper. Furthermore this study illuminated the new technology of modern molecular breeding that combines grading up and functional gene selection by Alpine dairy goat as male parent and Guanzhong dairy goat as female parent,which breed new varieties of high-quality and high-yield dairy goats suitable for intensive production. In brief,it is expected to effectively solve the issue of the dairy goat industrialization development in China,such as serious inbreeding,breast shape,significant difference of milk yield and composition and support the high-quality development of China dairy goat industry.
