摘要:

冷季牧草不足及营养品质下降是制约藏绵羊生产的重要原因之一,研究提高高寒牧区草地及藏绵羊的生产力势在必行。作者查阅了藏绵羊冷季燕麦青干草补饲方面的文献,综述了藏绵羊冷季补饲的迫切性、燕麦青干草生产研究现状、燕麦青干草补饲对藏绵羊消化性能、繁殖性能、生产性能及肉品质的影响,并针对今后燕麦青干草作为补饲草料在饲喂价值、补饲机制及冷季补饲技术的普及等方面提出一些建议,对燕麦青干草在藏绵羊补饲方面进行了展望,以期为藏绵羊生产中冷季补饲技术提供参考。

Abstract:

Lack of forage and lower nutrient level are limiting factors for Tibetan sheep production in cold season.It is imperative to improve the productivity of both alpine grassland and Tibetan sheep.In the light of research progress on oat hay supplementary feeding on Tibetan sheep in cold season,the authors reviewed the urgency of supplementary feeding,oat hay production and the research status,the effect of oat hay supplementary feeding on digestibility,reproduction,productive and meat quality in Tibetan sheep.Furthermore,we put forward some suggestions for the shortcomings of oat hay supplementary feeding on feeding value,supplementary feeding regime and the popularity of cold season supplementary feeding technology,in order to provide a reference for further research.

Key words: Oat hay; Tibetan sheep; supplementary feeding; digestibility; reproduction; meat quality
