The purpose of this research was to determine the impact of seasonality on feed balance in the Lalo kile district of the Kellem Wollega Zone of Western Ethiopia. The district was divided into two agro-ecological zones: mid and low altitude. A total of 127 respondents were chosen to be interviewed. To collect the required data in the study areas, a cross-sectional survey was used. To analyses the qualitative data, descriptive statistics were performed, while the General Linear Model (GLM) method was used to assess the impacts of seasonal feed availability and agro-ecology on dry matter yield and production constraints. The result showed that there has been seasonal fluctuation in the feed availability and the feed is generally abundant from June to September. The feed supply in terms of DM, ME, and DCP per household per year was 118.7 kg, 74,781 MJ/kg, and 118.61kg, respectively. The feed balance was negatively associated and substantially different all across the studied areas (P < 0.01). With a year's approach, the annual total feed supply exceeds only 66.13, 25.81, and 87.24 percent of the DM, DCP, and ME demands per household, respectively. As a result, total dry matter production, digestible crude protein, and metabolizable energy supply were only fulfilled for 9, 3.5, and 12 months in the research area's mid-altitude and 7, 3 and 9 months in the study area's low land altitude, respectively. The main limitations in both agro-ecologies of the research area include low production and reproduction, poor use of existing feedstuffs, and poor adoption of improved forage production. As a result, for successful livestock development in the study area, the adoption of better fodder and supplementation of productive animals should be considered.
本研究的目的是确定季节性对埃塞俄比亚西部凯莱姆沃莱加区拉洛基勒地区饲料平衡的影响。该地区分为两个农业生态区：中海拔和低海拔。总共选择了127名受访者进行访谈。为了在研究区域收集所需数据，采用了横断面调查。为了分析定性数据，进行了描述性统计，同时使用一般线性模型（GLM）方法评估季节性饲料供应和农业生态对干物质产量和生产限制的影响。结果表明，饲料供应存在季节性波动，6月至9月饲料通常较为充足。每户每年的干物质、代谢能和可消化粗蛋白饲料供应量分别为118.7千克、74781兆焦/千克和118.61千克。饲料平衡在所有研究区域均呈负相关且差异显著（P<0.01）。随着一年的推进，每年的总饲料供应量分别仅超过每户干物质、可消化粗蛋白和代谢能需求的66.13%、25.81%和87.24%。因此，研究区域中海拔地区干物质总产量、可消化粗蛋白和代谢能供应分别仅在9个月、3.5个月和12个月得到满足，低海拔地区分别为7个月、3个月和9个月。研究区域两个农业生态区的主要限制包括生产和繁殖率低、对现有饲料原料的利用不佳以及对改良牧草生产的采用率低。因此，为了研究区域畜牧业的成功发展，应考虑采用更好的饲料并对生产性动物进行补饲。
