苜蓿在畜禽鱼饲料中的应用研究进展

Progress situation on research and application of alfalfa in animal diet

介绍了苜蓿Medicago sativa的营养特性,重点论述了苜蓿在畜禽鱼饲料中的应用。苜蓿产品属于高蛋白、低消化能(粗纤维含量高)饲料,以适当比例添加到畜禽日粮中,可以显著提高其生产性能,改善肉、蛋的品质;苜蓿还可替代乳牛部分精料,提高乳脂率而不影响乳产量。但是,苜蓿草产品在肉牛饲养中应用较少,且苜蓿草产品单一,研究较注重苜蓿草粉,鲜草和由苜蓿加工制作的草颗粒、草块应用研究很少,在一定程度上限制了苜蓿产业的发展,应开发、采用新工艺加工草产品,降低生产成本,进一步研究苜蓿各类产品在畜禽饲料中的应用,为生产实践提供更准确、科学的依据。

Alfalfa products, with the features of high protein and low digestible energy feed （high crude fiber content）, could be added in animal diet by appropriate proportion. And it could significantly improve the animal production performance and the quality of meat or egg. Alfalfa could also partly replace the concentrates of cattle, and it could increase the milk fat percentage. However, the application of alfalfa products in beef cattle feeding is very poor, and only few products except alfalfa meal is in use, so the alfalfa industry is limited in some degree. So, the research work for new and low cost processing procedures should be strengthened.
