摘要

本研究旨在评估埃塞俄比亚南部Boran地区Moyale地区的主要牲畜饲料资源,并估计年饲料产量和饲料平衡。采用简单随机抽样的方法,选取96个具有代表性的家庭。数据收集采用小组讨论,结构化问卷,二手数据和个人观察。研究区确定天然牧草、作物残茬和农工副产品是畜禽的主要饲料资源。主要可利用饲料资源年平均生产饲料干物质(DM) 129,461.0156吨,牲畜存栏需水量为190,054.416吨DM/年,不足60,593.4004吨DM/年(31.88%)。据评估,干旱、饲料短缺、缺水、疾病和寄生虫、市场、盗窃和捕食者是牲畜生产的主要制约因素。总体而言,本研究结果证实,研究区不同饲料资源产生的干物质总量不足以满足研究区牲畜对干物质的需求,不足以支持研究区牲畜的生产,因此,需要通过修复污染牧区、引入合规饲料生产、改进饲料利用方法,引进和推广作物残茬饲料改良技术。关键词:饲料利用率,饲料平衡,饲料需求,饲料资源。

Estimation of major livestock feed resources and feed balance in Moyale district of Boran Zone, Southern Ethiopia
The study was conducted to assess the major livestock feed resources and estimating annual feed production and feed balance in Moyale district of Boran Zone, Southern Ethiopia. A simple random sampling technique was employed to select the household’s (HHs) and 96 representative households were selected. Data were collected using group discussions, structured questionnaire, secondary data and personal observations. As it was identified in the study district, natural pasture, crop residues and agro-industrial by-product were major feed resources for the livestock. An average of 129,461.0156 tons of feed dry matter (DM) per year was produced in the district from the major available feed resources, and the demand for maintenance requirement of the livestock population in the district was 190,054.416 (tons DM/year) and this showed that a deficit off 60,593.4004 (31.88%) tons of DM per year in the district. Drought, feed shortage, water scarcity, disease and parasite, market and theft and predator were assessed to be the major livestock production constraints. Generally, the results from this study confirmed that the total dry matter produced from different feed resources in to the study  area was not enough to satisfy the dry matter requirement of livestock to support the livestock production in to the study area, which suggest that the main focus needs to be refining the existing feed resources through restoration of tainted grazing areas, introduction compliant feedstuff production, improving feed utilization practices  and introduce and promote the crop residue feed improvement. Key words: Feed availability, feed balance, feed requirement, feed resources.
