绵羊妈妈和山羊妈妈在嗅觉识别的基础上与新生儿建立了早期的联系。我们调查了山羊是否也能够表现出早期（产后<24小时）的非嗅觉歧视他们的孩子，已经在绵羊中报道。在第一个实验中，我们发现，山羊不能识别他们的孩子在1米远的嗅觉线索的基础上。相比之下，他们表现出显着的偏好，为自己的孩子在一个两个选择测试，早在产后4小时，和哺乳期母亲嗅觉障碍并没有妨碍母亲的能力，以显示歧视。我们的结论是，山羊，绵羊一样，完全能够区分他们的新生儿没有嗅觉线索的帮助下，分娩后很早。由于年轻人的不同行为（孩子=隐藏者，羔羊=追随者），这两个物种之间的早期空间母子关系的差异，是不相关的显着差异的动态或机制控制的发展，其母亲的新生儿识别。
Mother sheep and goats develop an early bond with their neonate on the basis of olfactory recognition. We investigated whether goats were also able to show early (<24 hr postpartum) nonolfactory discrimination of their kids, as already reported in sheep. In a first experiment, we found that goats are not able to recognize their kid at 1 m away on the basis of olfactory cues alone. By contrast, they showed a significant preference for their own kid in a two-choice test as early as 4 hr postpartum, and prepartum maternal anosmia did not impede the ability of mothers to show discrimination. We conclude that goats, like sheep, are fully able to discriminate their neonate without the help of olfactory cues very early after parturition. The difference in the early spatial mother-young relationship between the two species due to the different behavior of the young (kids = hiders, lambs = followers), is not associated with marked differences in the dynamics or mechanisms controlling the development of recognition of the neonate by its mother.
