从全世界的角度来看，山羊既被憎恨又被珍惜，因为它在严重过度放牧和侵蚀的地区生存并保持多产。山羊可能不是牧场退化的最初原因，但它们可能是破坏后期的罪魁祸首。山羊在饮食选择和胃肠道生理方面与其他家畜（牛和羊）不同，与鹿相似。这些差异解释了为什么山羊的高需求可以在其他动物不满意的环境条件下得到满足。一些实验证据表明，山羊的消化能力更强；然而，这种优势可能只存在于某些具有可定义解剖尺寸的品种或品系中，而不是整个山羊种群的特征。实验证据表明，与高度发达的奶牛相比，奶山羊在产奶效率方面没有明显的优势；然而，在世界上的许多情况下，由于可利用的资源和动物的适应性，山羊可能比牛更有效地产奶。
Abstract The goat, from a world wide view, is both hated and treasured because it survives and remains productive in areas that are seriously overgrazed and eroded. Goats are probably not the initial cause of rangeland deterioration, but they may be the primary culprit during the latter stages of destruction. Goats are presented as being different in diet selection and gastrointestinal physiology from other domestic animals (cattle and sheep) and similar to deer. These differences offer explanations of why the goat's elevated requirements can be satisfied under environmental conditions unsatisfactory for other animals. Some experimental evidence indicates that the goat has greater digestive capacity; however, this advantage is likely only in certain breeds or strains having definable anatomical dimensions and is not a characteristic of the entire goat population. Experimental evidence suggests that the dairy goat does not hold a distinct advantage in efficiency of milk production over the highly developed dairy cow; however, it is likely that under many circumstances in the world, milk can be produced more efficiently from goats than from cattle due to resources available and adaptability of the animals.
