1加工工艺对饲料营养物质组成、消化率和抗营养因子等指标的影响显示文摘本文阐述了饲料生产过程中机械加工和湿热加工对家禽和猪的饲料的物理性状、化学组成以及淀粉与蛋白质的消化率的影响。饲料粒径的减小会导致家禽的肌胃发育不良,也会造成猪发生胃溃疡,这与细粉碎带来的后果相一致,也是制粒、膨胀和膨化等湿热加工产生的常见后果。不溶性纤维具有高耐磨性,在饲料中添加含有此类纤维的结构性饲料成分,可能会部分抵消用上述加工工艺生产的饲料对猪和家禽造成的不良影响。对家禽和猪的饲料进行湿热加工可以改善饲料的卫生状况,减少饲料的浪费,增加动物的采食量,减少动物采食时的能量消耗,并且还可能会减少饲料中过敏原蛋白和抗营养因子的含量。对饲料进行湿热加工会影响家禽对日粮淀粉的回肠消化率,但有利于猪对日粮淀粉的回肠消化率。与目前业界普遍认同的观点相反,湿热加工对饲料中蛋白质的化学和物理性质及其消化率的直接影响可以忽略不计,即使有影响,也不一定会提高日粮蛋白质的消化率。然而,强度更大的湿热加工,即膨胀加工和膨化加工,可以减少饲料原料中抗营养因子的含量,进而提高家禽和猪日粮蛋白质和氨基酸的消化率。Jürgen Zentek Farshad Goodarzi Boroojeni 韩浩月(译) 孟祥光(校) 张配配(审) 韩浩月(制表) 2021国外畜牧学(猪与禽)2021,41,6:3
2Lignocellulose as an insoluble fiber source in poultry nutrition:a review显示文摘Extensive research in recent years into the use of various fiber sources in poultry nutrition has led to the perception that dietary fiber is more than a simple diet diluent.Several studies showed that the feeding of insoluble fiber sources such as oat hulls,sunflower hulls or wood shavings may affect digestive physiology and function improving chickens health and growth performance.In this context,the effect of lignocellulose as an insoluble dietary fiber source is increasingly being investigated.Lignocellulose is a component of plant cell walls and consists mainly of the insoluble carbohydrate polymers cellulose and hemicelluloses as well as the phenolic polymer lignin.Lignocellulose is chemically and physicochemically different from other insoluble fiber sources and thus possibly has different effects on poultry compared to traditional fiber sources.Several studies investigated the effect of dietary lignocellulose on growth performance,nutrient digestibility,gastrointestinal tract development and intestinal microbiota in broilers and laying hens.Studies differed in terms of feed formulation and lignocellulose inclusion level as well as products of different suppliers were used.The results obtained are inconsistent;beneficial,indifferent or detrimental effects of feeding lignocellulose were observed,so that a final assessment of lignocellulose as a“novel”insoluble fiber source is difficult.This review article summarizes the results of studies in connection with the feeding of lignocellulose to poultry,compares them with those that have used other insoluble fiber sources and illuminates the possible mechanisms of action.Ilen Röhe Jürgen Zentek 2021Journal of Animal Science and Biotechnology2021,12,4:2

14生物技术发酵对饲料营养物质组成和消化率等指标的影响显示文摘本文阐述了饲料生产过程中的生物技术发酵对家禽和猪的饲料的物理性状、化学组成以及淀粉与蛋白质的消化率的影响。湿热加工,即膨胀加工和膨化加工,可以通过减少饲料原料中抗营养因子的含量提高家禽和猪日粮蛋白质和氨基酸的消化率,但发酵过程也可以有效减少饲料中的抗营养因子含量,并可改变猪和家禽的肠道菌群组成。然而,发酵加工对饲料原料的营养组成及其消化率的影响并不一致,这很大程度上取决于发酵类型、发酵周期、所用发酵剂、发酵过程中主要微生物的酶学特征、饲料原料的类型及其化学组成。Jürgen Zentek Farshad Goodarzi Boroojeni 韩浩月(译) 孟祥光(校) 张配配(审) 韩浩月(制表) 2021国外畜牧学(猪与禽)2021,41,6:1
