全球动物源食品需求和产量的增长（1960 年至 2015 年间增长了四到五倍）主要集中在低收入和中等收入国家 (LMIC)，为小农畜牧生产者提供了改善生计以及粮食和营养安全的机会。然而，在许多中低收入国家的畜牧生产系统中，优质饲料的供应有限和成本高昂，严重限制了这一机会的利用。在许多此类国家，饲料和饲养相关问题往往被列为畜牧生产和动物源性食品消费增加的主要制约因素。在这里，我们回顾了与提高饲料质量供应相关的复杂的生物物理、社会经济和技术挑战，以及明显经过验证的饲料强化技术普遍采用率较低的原因。我们还描述了成功的干预措施，并最后提出了改善中低收入国家优质饲料供应的策略，以解决并克服当前的挑战。发展中国家的畜牧业生产受到优质饲料供应有限的限制。有许多技术可以改善小农生产者的优质饲料供应。复杂的生物物理和社会经济因素限制了技术的采用，从而限制了优质饲料供应的改善。饲料改良技术的失败是由于系统性限制以及对社会文化和经济因素关注不足造成的。成功往往是由市场激励和/或为多种问题提供解决方案的创新的、负担得起的方法所驱动的。
The global increase in the demand for and production of animal-source foods (four-to five-fold increase between 1960 and 2015), which has been mostly concentrated in low- and middle-income countries (LMIC), provides smallholder livestock producers with an opportunity for improving their livelihoods and food and nutrition security. However, across livestock production systems in many LMIC, limited supplies and high cost of good quality feed severely constrains exploitation of this opportunity. In many of such countries, feeds and feeding-related issues are often ranked as the primary constraint to livestock production and increased consumption of animal-source foods. Here we review the complex biophysical, socio-economic and technological challenges related to improving quality feed supply and the reasons for generally low adoption of apparently proven feed enhancement technologies. We describe also successful interventions and conclude by recommending strategies for improving quality feed supply in LMIC that account for and overcome the prevailing challenges. Livestock production in developing countries is constrained by limited supply of quality feeds. There are many technologies that can improve supply of quality feed for small holder producers. Complex set of bio-physical and socio-economic factors limit the adoption of technologies and thus limit the improvement in supply of quality feed. The failures of adoption of feed improvement technologies result from systemic constraints and inadequate attention to sociocultural and economic factors. Success is often driven either by market incentives and or an innovative affordable approach that provides solutions to multiple problems.
