摘要

本研究评估了埃塞俄比亚主要饲料产品的价格质量关系,目的是向决策者提供该国发展牲畜饲料部门的可能途径。2019年4月至5月在五个地区(阿姆哈拉、南部民族和民族地区、奥罗米亚、提格雷和亚的斯亚贝巴)开展了一项牲畜饲料市场调查。从202个市场共收集了1700份饲料样本及其各自的价格信息。测定样品的粗蛋白质(CP)、中性洗涤纤维(NDF)、酸性洗涤纤维(ADF)、体外有机物消化率(IVOMD)和代谢能(ME)含量。结果显示,在同一饲料类型中,质量有相当大的差异。Pearson相关分析和回归分析表明,饲料样品的价格质量关系非常弱或不存在。麦麸的CP (r= 0.200, P<0.01)、ME (r= 0.202, P<0.01)和IVOMD (r= 0.221, P<0.01)的价格与质量呈弱相关。粗饲料中,草料价格与代谢能呈微正相关(r= 0.382, P<0.001),与ADF呈微负相关(r=-0.336, P< 0.005)。本研究的结果表明,质量属性在埃塞俄比亚饲料市场上大多数饲料类型的市场价格设定中没有作用,或者作用有限。优质饲料和劣质饲料都以相同的标签和市场价值出售,这一事实对贸易商和牲畜生产者都有影响。因此,重要的是建立国家饲料分析能力,以便根据国家饲料标准检查饲料质量,特别是精料饲料。

Price-quality relationships for the main livestock feed types in the Ethiopian feed market
This study assessed the price-quality relationships for the major feed products in Ethiopia with a view to informing policy makers on possible avenues to develop the livestock feed sector in the country. A survey of livestock feed markets was conducted from April to May 2019 in five regions (Amhara, Southern Nations Nationalities and Peoples Region (SNNPR), Oromia, Tigray and Addis Ababa). A total of 1700 feed samples with their respective price information were collected from 202 marketplaces. The collected samples were analyzed for their crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (ADF), in vitro organic matter digestibility (IVOMD) and metabolisable energy (ME) content. Results showed considerable variability in quality within the same feed type. Pearson correlation and regression analyses showed that price-quality relationships for the feed samples were either very weak or non-existent. Wheat bran showed a weak price to quality correlation for CP (r= 0.200 at P<0.01), ME (r= 0.202 at P<0.01) and IVOMD (r= 0.221 at P<0.01). Among the roughages, grass hay showed slight positive price to ME correlation (r= 0.382 at P<0.001) and a slight negative relationship with ADF (r=-0.336 at p<0.005). The results of this study indicated that quality attributes have no, or a limited role in setting market prices for most feed types in the Ethiopian feed market. The fact that both good and poor-quality feeds are sold under the same label and market value affects both traders and livestock producers. Therefore, it is important to build national feed analytical capabilities to allow quality of feeds to be checked against national feed standards, particularly for concentrate feeds.
