氨化饲料在畜牧生产中的应用

Application of Ammoniated Feed in Livestock Production

氨化饲料是将切碎的秸秆等农作物装入窖内或堆放后利用液氮、尿素和碳酸氢铵等氨源进行化学处理的粗饲料,一般需要密封保存1周以上才可制成,主要为了增加供给食草牲畜饲料中的氮素含量。在秸秆等农作物中添加氨源制成的饲料,有效提高粗纤维的可消化性,在促使秸秆等农作物纤维结构产生改变的同时,增加饲料的适口性,显著提升采食量和消化率,是冬、春等枯草季节食草牲畜的主要饲料之一。

Ammoniated feed is a kind of roughage that is put chopped straw and other crops into pits or stacked for chemical treatment with ammonia sources such as liquid nitrogen,urea and ammonium bicarbonate.It can be made only after being sealed for more than a week,mainly to increase the nitrogen content in the feed for grazing livestock.Feed made by adding ammonia source to crops such as straw can effectively improve the digestibility of crude fiber.While promoting the change of fiber structure of crops such as straw,it can increase the palatability of feed,significantly improve the intake and digestibility.It is one of the main feeds for grazing livestock in dry seasons such as winter and spring.
