摘要

与世界牲畜总数量相比,东非国家的牛(9.3%,1.364 亿头)和小型反刍动物(12%,2.534 亿只)数量占很大比例。该地区 70% 以上的土地有利于饲养红肉动物。然而,由于达不到最低质量标准,该地区肉类产品在世界市场上的份额有限(约 1%)。该地区的大多数畜牧业主都是小农户,他们经营着牧业和作物-畜牧业混合生产系统。本研究以埃塞俄比亚为例,考察了有关小农生产系统生产的牛肉质量的报告,以确定小农生产系统生产优质牛肉的潜力和决定因素。为此,研究人员将研究站的牛肉质量报告作为标准,以比较小农户在作物-牲畜混合系统、牧场和哈拉盖育肥牛系统中饲养的黄牛和公牛所报告的牛肉工具质量。分析结果表明,与哈拉盖育肥牛和牧场牛相比,作物-畜牧混合系统小农户饲养的黄牛生产的牛肉质量较低,而牧场系统饲养的公牛生产的牛肉质量较高。Hararghe 牛育肥系统使用的是改良饲料资源;黄牛用于短时间(2.85 ± 0.58 年)的役畜,然后在相对较小的年龄出售宰杀。在牧区,牧场为有效利用稀缺饲料资源提供了选择。决定作物-畜牧混合系统中饲养的黄牛所产牛肉质量的主要因素是饲料资源质量差、长期服役(6.62 ± 1.92 年)和屠宰年龄大。为了提高作物-家畜混养系统中饲养的黄牛所产牛肉的质量,需要采用 Hararghe 牛育肥系统中小农的做法。采用这种做法还有助于减少该系统的温室气体排放,并将自给自足的作物-牲畜混合系统转变为以市场为导向的系统。

Opportunities to Improve the Quality of Beef Produced under Smallholder Mixed Crop and Rangeland Livestock Production Systems
East African countries contain a substantial proportion of cattle (9.3%, 136.4 million) and small ruminants (12%, 253.4 million) compared to the world’s total livestock population. In this region, more than 70% of the land surface is conducive to raise red meat animals. However, the region has limited share (approximately 1%) of meat products to the world market due to the failure to satisfy the minimal quality standard. Most of livestock farmers in this region are smallholders operating pastoral and mixed crop-livestock production systems. This study looked at reports on the quality of beef produced by smallholder production systems using Ethiopia as an example in order to identify potential and determinants in quality beef production under smallholders production system. In order to achieve this, research station beef quality reports were considered as a standard to compare the instrumental quality of beef reported from oxen and bulls raised by smallholders in mixed crop-livestock systems, ranches, and Hararghe cattle fattening systems. According to the analysis, oxen in the smallholders in the mixed crop-livestock systems produced comparatively lower-quality beef than oxen reared by the smallholders in the Hararghe fattening and bulls reared in the ranch systems, which produced good-quality beef. Improved feed resources are used in the Hararghe cattle fattening systems; oxen are used for draft service for a brief period of time (2.85 ± 0.58 years) and then sold for slaughter relatively at a young age. In pastoral settings, ranches offer options for the effective use of scare feed resources. The primary factors that determine the quality of beef produced from oxen raised in the mixed crop-livestock system were poor-quality feed resources, long-term draft service (6.62 ± 1.92 years), and old age at slaughter. To improve the quality of beef produced from the oxen raised in the mixed crop-livestock system, the practice of smallholder farmers in the Hararghe cattle fattening system needs to be adopted. The adoption of the practice also contributes to reduce the greenhouse gas emissions from the system and convert the subsistence mixed crop-livestock into a market-oriented system.
