尿素作为一种应用广泛的反刍动物蛋白质替代饲料,其特殊的异味以及释放氨的速度太快,利用率低、危险性大。因此使用尿素时应有适量的、易分解的碳水化合物。利用膨化技术使淀粉通过机械作用,生成改性淀粉α-糊化淀粉。它具有很强的吸水性和粘接功能,不仅使尿素扩散在其中,也可 Urea as a widely used ruminant protein instead of feed, its special smell and the release of ammonia too fast, low utilization, dangerous. Therefore, the use of urea should be appropriate, easy to break down carbohydrates. Using puffing technology to make starch through mechanical action, to generate modified starch α-gelatinized starch. It has a strong water absorption and bonding capabilities, not only in which urea spread, but also
