Abstract

Over the recent years, Sub-Saharan Africa (SSA) has seen an increase in population growth, urbanization, and per capita income. As a result, there has been a corresponding increase in the demand for animal source foods. In order to meet this demand, most countries have resorted to intensifying the production of conventional livestock. However, this increase in production comes with several environmental, nutritional, gender-related and economic challenges that are a rising concern. It is therefore imperative to explore the comparative advantages and disadvantages of other livestock species, which are currently consumed in SSA but are not recognised in widely adopted policies. Herein, using a novel conceptual framework, we present a systematic review of four selected neglected species, namely, grasscutter, guinea fowl, guinea pig, and rabbit. The review was conducted following the checklist for Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA), and 89 sources of literature were included. The results highlight that embracing these neglected livestock species could confer several benefits, including an enriched nutritional profile (high-quality protein, low fat, high dressing percentage), increased gross economic returns, environmental sustainability, and sustained empowerment of minority groups, especially women. Overall, this review shows the untapped nutritional and socio-economic potential of neglected livestock species, which, if incorporated into mainstream production, could improve food security and reduce unemployment in SSA.

撒哈拉以南非洲被忽视的牲畜品种是否存在未被认识到的潜力？四种选定物种的系统综述

近年来，撒哈拉以南非洲（SSA）的人口增长、城市化和人均收入都有所增加。因此，对动物源食品的需求也相应增加。为了满足这一需求，大多数国家都采取了加强传统牲畜生产的办法。然而，这一产量增长带来了一些环境、营养、性别和经济方面的挑战，这些挑战日益受到关注。因此，有必要探讨其他牲畜物种的相对优势和劣势，这些物种目前在非洲南部被消费，但在广泛采用的政策中尚未得到承认。本文采用一个全新的概念框架，对四种被忽视的物种，即割草动物、珍珠鸡、豚鼠和兔子进行了系统的综述。按照系统评价和荟萃分析首选报告项目清单（PRISMA）进行综述，纳入了89篇文献。研究结果强调，接纳这些被忽视的牲畜物种可以带来一些好处，包括丰富的营养状况（高质量的蛋白质、低脂肪、高屠宰率）、增加总经济回报、环境可持续性以及持续赋予少数群体（特别是妇女）权力。总的来说，这篇综述显示了被忽视的牲畜物种尚未开发的营养和社会经济潜力，如果将其纳入主流生产，可以改善粮食安全并减少SSA的失业率。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
