In 1994 and 1995 leaves from 10 selected West African trees and shrubs with varying tannin content were tested to determine their suitability as an alternative and supplementary browse feed for West African dwarf sheep to improve productivity in small-scale holdings in Benin. Dry matter intake per kg metabolic body weight (DM g/kg W0.75) varied between the different browse feeds and between the different trials and ranged from zero (Leucaena leucocephala) up to 26.7 DM g/kg W0.75 (Margaritaria discoidea). The digestibility of the organic matter varied between 58.9% (L. leucocephala) and 68.2% (Mallotus oppositifolius). Agelaea obliqua showed the highest levels of total phenols (10.2%), tannin phenols (8.8%) and extractable condensed tannins (8.0%). Leaves from various browse feeds are a good and protein-rich supplementary fodder in addition to the grass Panicum maximum. However, feeding of A. obliqua and Cnestis ferruginea should be avoided due to toxic components.
1994年和1995年，对10种选定的、单宁含量各异的西非树木和灌木的叶子进行了测试，以确定它们作为西非矮脚羊替代和补充粗饲料的适宜性，从而提高贝宁小规模养殖场的生产力。每千克代谢体重的干物质摄入量（DM g/kg W0.75）在不同的粗饲料之间以及不同的试验之间有所不同，范围从零（银合欢）到26.7 DM g/kg W0.75（圆盘珍珠菜）。有机物的消化率在58.9%（银合欢）至68.2%（白背叶野桐）之间变化。斜叶银柴的总酚（10.2%）、单宁酚（8.8%）和可提取缩合单宁（8.0%）含量最高。除了大黍草之外，各种粗饲料的叶子都是优质且富含蛋白质的补充饲料。然而，由于含有有毒成分，应避免投喂斜叶银柴和铁锈叶咀签。
