摘要

由于欧盟需要提高植物蛋白的自给率，猪饲料中含有高纤维和高蛋白质的副产品的使用有所增加。本试验旨在评价两期饲喂体系中饲粮NDF水平较高时，增加副产物添加量对生长育肥猪生长性能和饲料效率的影响。单户杂交(DanBred)猪(n = 60;试验选用41 kg初始体重。在第一阶段和第二阶段分别配制无副产物的对照饲料(CTR)、中等副产物饲料(MLB)和高副产物饲料(HLB)，分别为15%和20%和27%和33%。试验饲料按净能(NE)计算为等能饲料。整个试验期间，各试验组猪的增重均在1000 g/d以上，且无显著(P > 0.05)处理效果、性别和日粮×性别交互作用。

The effect of inclusion of fibre-rich by-products on the performance of growing and finishing pigs (pilot study)

ABSTRACT The use of by-products containing high fibre and protein has increased in pig feeding due to the need of the increase of the plant protein self-sufficiency of the EU. The aim of this experiment was to evaluate the effect of increasing by-products inclusion on growth performance and feed efficiency in growing-finishing pigs in the course of using a relatively high dietary NDF level in two-phase feeding system. Individually housed hybrid (DanBred) pigs (n = 60; 41 kg initial BW) were used in the trial. Control (CTR) feed was formulated without by-products, moderate (MLB) with 15% and 20% and high level of by-products feed (HLB) with 27% and 33% by-products, in phase 1 and 2, respectively. Experimental feeds were isocaloric on net energy (NE) basis. Pigs gained over 1000 g/d in all experimental groups for the whole trial and no significant (P > 0.05) treatment effect, sex and diet × sex interactions were observed.
