Equines have been largely ignored in modern scientific literature on domestic animals, probably because they are not providers of meat and milk. Their contribution to the economy in the Sudan, however, is considerable and they are the principal means of transport both as baggage and as riding animals. They also play an important role in the supply of fuel and the distribution of domestic water in the larger villages and towns. Information on population structure is provided and descriptions, with particular reference to withers height and weight, are given of two types of donkey and of the horse. Growth curves have been derived, formulae for estimating weight from girth provided, and mean population weights, which can be expressed in terms of livestock units, have been calculated.
在现代关于家畜的科学文献中，马科动物在很大程度上被忽视了，这可能是因为它们不提供肉和奶。然而，它们对苏丹经济的贡献相当大，并且作为驮畜和乘骑动物，它们是主要的运输工具。在较大的村镇，它们在燃料供应和生活用水分配方面也发挥着重要作用。文中提供了有关种群结构的信息，并对两种驴和马进行了描述，特别提及了鬐甲高度和体重。得出了生长曲线，给出了根据胸围估算体重的公式，并计算了平均种群体重，这些体重可以用牲畜单位来表示。
