饲料中粗料较难消化。这不仅由于其粗纤维含量高而影响猪体对有机物的消化,同时由于粗蛋白质含量低,影响藏香猪的食欲消化液的分泌以及消化管内微生物的活动,不利于消化。采食量多,饲料通过消化管的速度加快,消化吸收不充分消化率也低。饲料在饲喂前经过物理(粉碎等)或微生物方法(发酵)的加工调制,可以改善其消化性,提高藏香猪饲料的消化率。
Coarse material in feed is difficult to digest. This is not only due to the high content of crude fiber but also the * * digestion of organic matter in pigs. At the same time, due to the low content of crude protein, the secretion of digestive juice and activities of microbes in the digestive tube are not conducive to digestion. Feed intake is high, feed speeds up through the digestive tube, and digestion and absorption are not fully digested. The feed can be digested by physical crushing or microbial methods fermentation before feeding, which can improve its digestibility and improve the digestibility of * Xiang Xiang pig feed.
