摘要
水稻是我国重要的粮食种类之一,在加工成大米的工序中,会产生一系列的副产物,如稻壳、碎米、米糠及秸秆等.碎米和米糠的营养价值较高,可以直接添加在畜禽饲粮中或加工处理后替代部分能量饲料,具有改善动物生产性能和降低养殖成本等优势.稻壳和秸秆营养价值较低,利用效率不高,只有部分被用于肉牛、奶牛、羊和鹅饲料中.近年来,采用物理、微生物和酶等技术处理水稻加工副产物的研究较多,这些技术可以改善稻壳和秸秆的营养价值和适口性,提高利用效率.文章综述了水稻副产物(稻壳、碎米、米糠、秸秆)的营养价值、加工方式及其对家禽、猪、反刍动物和水产动物的生长性能、消化利用率和肠道发育等指标的影响,为水稻副产物饲料资源化利用提供参考.
Abstract
Rice is one of the important food crops in China.During the process of milling them into rice grains,a series of by-products are produced,such as rice husks,broken rice,rice bran,and straw.Broken rice and rice bran have high nutritional value and can be directly added to livestock feed or used as a substitute for some energy feed after processing,offering advantages such as improving production performance and reducing costs.Rice husks and straw have low nutritional value and are not efficiently utilized,with only a portion being used in the feed for cattle,dairy cows,sheep,and geese.In recent years,there has been extensive research on the treatment of rice processing by-products using physical,microbial,and enzymatic methods,which can improve the nutritional value and palatability of rice husks and straw,thereby increasing their utilization efficiency.This article reviews the nutritional value,processing methods,and the impact on the growth performance,digestibility,and intestinal development of rice by-products(rice husks,broken rice,rice bran,straw)for poultry,pigs,ruminants,and aquatic animals,providing a reference for the utilization of rice by-products as feed resources.
