摘要

土鸡生产包括一系列对非洲小农家禽饲养者非常重要的活动。影响其生产和威胁当地粮食安全的众多因素之一是营养问题,特别是与蛋白质补充有关的问题。农民现有的饲料资源不足以维持鸡的生产力。因此,鸡的饮食往往需要营养补充。因此,迫切需要对当地种植的饲料原料进行验证,以提高撒哈拉以南非洲地区家禽生产的可持续性。苜蓿(Medicago sativa)又称紫花苜蓿,是一种可用于鸡日粮的饲料原料。在南非,苜蓿是种植最多的饲用豆科植物,年产量约为 130 万公吨。苜蓿的营养价值很高,因为它是蛋白质、氨基酸、维生素和脂肪酸的来源。因此,应研究苜蓿作为土鸡饲料资源的潜力,以制定改善土鸡营养的战略。本综述旨在强调苜蓿作为本地鸡潜在饲料成分的重要性,并讨论其对肉鸡、蛋鸡和两用鸡生产率的影响。

Lucerne meal in the diet of indigenous chickens: a review
Indigenous chicken production consists of an array of activities important to smallholder poultry farmers in Africa. One of the many factors influencing their production and threating the local food security is in the area of nutrition, particularly, that related to protein supplementation. The available feed resources to farmers are not enough to sustain the productivity of the chickens. Hence, the chickens’ diets often require nutritional supplementation. There is therefore an urgent need for the validation of locally grown feed ingredients to improve the sustainability of poultry production in sub-Saharan Africa. A dietary ingredient that may be used in the diets of chickens is lucerne (Medicago sativa), which is also known as alfalfa. In South Africa, lucerne is the most cultivated forage legume and approximately 1.3 million metric tonnes of lucerne are produced per year. Lucerne has high nutritional value, as it is a source of protein, amino acids, vitamins, and fatty acids. The potential of lucerne as a feed resource for indigenous chickens should, therefore, be investigated so that strategies to improve the nutrition of such chickens can be developed. The purpose of this review was to highlight lucerne as a potential dietary ingredient for indigenous chickens and discuss its effects on the productivity of broilers, egg-layers, and dual-purpose chickens.
