紫花苜蓿对母猪生产性能的影响

Effect of alfalfa on the reproduction of sows

紫花苜蓿Medicago sativa粗蛋白含量高,氨基酸平衡,粗纤维利用率高,且含有丰富的维生素、矿物质,其中的β-胡萝卜素、维生素E、维生素B2、叶酸和硒等可以降低母猪胚胎死亡率,增加窝产仔数,延长母猪的利用年限。因此,在母猪饲粮中添加适量紫花苜蓿鲜草或草粉代替部分精料,能降低饲料成本,提高母猪的生产性能。研究主要综述了紫花苜蓿粗纤维和几种重要维生素对母猪生产性能的影响。

Alfalfa is a ideal forage fodder for sow,as it contained high content of crude protein,balanced amino acid,rich in vitamins and minerals,easy can be utilized crude fiber,especially,β-carotene,vitamin E,vitamin B2,folic acid and selenium can reduce the embryo mortality,increase offspring number,and increase effective reproduction age.The advantage of adding the appropriate amount of alfalfa into sow feed in fresh or dry powder can reduces product cost.This article mainly summarized the effect of alfalfa crude fiber and several important vitamins on the sow production.
