摘要
本试验旨在评价在尿素处理tef (Eragrostis tef)秸秆(UTTS)饲粮中添加麦麸(WB)对阿法尔羊饲料利用率和胴体特性的影响。选取16只初始体重(BW)为15.75±1.57 kg (mean±SD)的完整阿法尔羊和16只阉割的阿法尔羊，采用完全随机区组设计，分为2个性别(完整、T1-T4和阉割、T5-T8) × 4个水平(0，对照组;150克，低;250克，中号;在干物质(DM)基础上添加350 g(高)的WB。饲粮添加后提高了总干物质、粗蛋白质(CP)采食量、末体重、日增重、饲料转化率、肋眼肌面积(P);尸体;消化率;采食量;尿素处理Tef秸秆;麦麸
Supplementation of Graded Levels of Wheat Bran to Intact and Castrated Afar Sheep Fed Urea Treated Tef Straw: Effects on Feed Intake, Digestibility, Body Weight and Carcass Characteristics
A feeding and digestibility trial was conducted to evaluate the effect of wheat bran (WB) supplementation on feed utilization and carcass characteristics in urea treated tef (Eragrostis tef) straw (UTTS) based feeding of Afar sheep. Sixteen intact and sixteen castrated Afar sheep with initial body weight (BW) of 15.75 ± 1.57 kg (mean ± SD) were used in a randomized complete block design with 2 sex (intact, T1-T4 and castrated, T5-T8) x 4 levels (0, control; 150 g, low; 250 g, medium; 350 g, high) of WB supplementation on a dry matter (DM) basis. Supplementation promoted higher total DM, crude protein (CP) (P intake, final BW, daily BW gain, feed conversion efficiency (FCE), rib-eye muscle area (P Keywords: Afar Sheep; Carcass; Digestibility; Feed Intake; Urea Treated Tef Straw; wheat bran
