通过日粮调控减少猪排泄物中氨与硫化氢的产生与散发量

随着畜牧生产规模的不断扩大和集约化程度的不断提高，畜禽排泄物对环境的污染已受到普遍重视。本文从六方面系统综述了通过日粮调控减少猪排泄物中氨与硫化氢产生与散发量的潜力，其中包括：（1）添加合成氨基酸以降低饲粮蛋白水平；（2）增加饲粮中非淀粉多糖含量；（3）改变饲粮组分以降低排泄物的pH值；（4）调控消化道微生物；（5）添加非营养性添加剂；（6）选用含硫量较低的饲料原料。

Reduction of Ammonia and Odour Release by Adjustment of Pig Ration

The pollution of domestic animal excrement on enviroment was more regarded with expand scale of animal production and increase of intensive. The measure reducing release of Ammonia and Odour was instead of part protein with synthesis amino acid, increase of non finite amylose,alter of ration to decrease pH, control of microbe in alimentary tract,appending non nutrition additive and using low sulfur feedstuff.
