The accessory olfactory bulb (AOB) is the primary target of the sensory epithelium of the vomeronasal organ (VNO), and thus constitutes a fundamental component of the accessory olfactory system, which is involved in responses to behaviour-related olfactory stimuli. In this study we investigated the characteristics of the AOB, VNO, vomeronasal nerves (VNNs) and caudal nasal nerve (CdNN) in pigs and sheep, species in which olfaction plays a key behavioural role both in the neonatal period and in adulthood. The patterns of staining of the AOB by the Bandeiraea simplicifolia and Lycopersicon esculentum lectins were the same in the 2 species, whereas the Ulex europeus and Dolichos biflorus lectins gave different patterns. In both species, lectin staining of the AOB was consistent with that of the VNNs, while the CdNN did not label any of the structures studied. The entire sensory epithelium of the pig was labelled by Ulex europeus and Lycopersicum esculentum lectins, and all 4 lectins used labelled the mucomicrovillar surface of the sensory epithelium in sheep.
副嗅球（AOB）是犁鼻器（VNO）感觉上皮的主要靶器官，因此构成了副嗅觉系统的基本组成部分，该系统参与对行为相关嗅觉刺激的反应。在本研究中，我们调查了猪和羊的副嗅球、犁鼻器、犁鼻神经（VNNs）和鼻后神经（CdNN）的特征，在这两个物种中，嗅觉在新生期和成年期都起着关键的行为作用。在这两个物种中，简单叶豆凝集素和番茄凝集素对副嗅球的染色模式相同，而欧洲荆豆凝集素和双花扁豆凝集素给出了不同的模式。在这两个物种中，副嗅球的凝集素染色与犁鼻神经的染色一致，而鼻后神经未标记所研究的任何结构。猪的整个感觉上皮被欧洲荆豆凝集素和番茄凝集素标记，并且所使用的所有4种凝集素都标记了绵羊感觉上皮的黏液微绒毛表面。
