摘要

在Arsi牛(Bos indicus)秸秆饲料中，每头牛每天添加1、2或4 kg的藜麦(Guizotia abyssinica)粉，持续90 d，可改善生长参数。饲粮的添加显著提高了采食量、平均日增重以及屠宰胴体和瘦肉的体重。饲粮中添加1公斤营养膳食是最有利可图的，每头动物的净收益为17.10美元，而仅饲喂tef秸秆的每头动物的净收益为18.66美元。版权所有©2007 John Wiley & Sons, Ltd

Effect of supplementation of tef (Eragrostis tef) straw with different levels of noug (Guizotia abyssinica) meal on worked Arsi oxen (Bos indicus)

Supplementing the tef (Eragrostis tef) straw feed of Arsi oxen (Bos indicus) with 1, 2 or 4 kg per animal per day of noug (Guizotia abyssinica) meal for 90 days improved growth parameters. Supplementation significantly increased feed intake, average daily gain, and the weight of dressed carcass and lean meat. Supplementation with 1 kg of noug meal was the most profitable, giving a net return per animal of US$17.10, whereas a sole diet of tef straw gave a loss of US$18.66 per animal.
