乳酸菌青贮与自然青贮的质量及其对反刍动物的影响

The Quality and Effects of Nature Silage and Inoculated Silage on Ruminat Animal Performance

青贮是保存新鲜粗饲料的重要手段,能确保动物常年有质量稳定的新鲜粗饲料可以食用。粗饲料原料自身特性、气候因素、青贮的过程,以及开封后的管理等因素都会影响到青贮饲料的质量。青贮添加剂,特别是乳酸菌青贮添加剂的使用,可以在饲草发酵过程中产生大量的有机酸加速青贮发酵过程,降低干物质的损失,延长开封后的好氧稳定性,提高营养价值与适口性并且能提高动物的经济效益,在提升青贮质量上扮演重要的角色。

The making of silage is a very important mean to preserve fresh forage as a steady and stable feed for animals. Forage itself, climate, the ensiling process and the management of feedout, all determine the final silage quality. Silage additives, especially the bacterial inoculants ferment the carbohydrates into large amount of organic acids that reduce the pH, speed up the ensiling process, extend the aerobic stability, improve the nutritional value and palatability and economic performance of the animals.
