 Highlights 
● Temperament modifies the responses to stressors and impacts the production capacity and welfare of ruminants.
● While molecular studies have identified central pathways that shape temperament, emerging evidence links the rumen microbiome to behavior.
● Future work may enable microbiome-based interventions to modify temperament, improving animal health and welfare.

摘要  

在过去的几十年里,经过对反刍动物性情的长期研究,发现其与人类性格存在着众多相似之处。性情主要指动物对具有挑战性的生存环境所做出的一系列反应的总称。因此,动物性情能够影响动物大部分生理功能,主要表现在通过调控压力反应轴,影响与动物生产性状及健康福利相关的其他功能。因此,了解动物性情调控因子变得至关重要。性情特征的一个重要调控因素是个体对于压力源的感知方式。利用分子手段进行的研究已经证实并确定了部分参与性情调控的中心途径。近期研究发现,与单胃动物肠道菌群参与大脑中通路调控类似,反刍动物瘤胃微生物也可以通过类似方式在性情调控中发挥重要作用。因此,阐明瘤胃微生物和反刍动物性情之间相互作用的关系需要进一步研究探索,从而实现通过调控瘤胃微生物能够修饰改善反刍动物性情,进而提高动物健康与福利。



Abstract  

The temperament of ruminants has been investigated for several decades and has similarities with human temperament. Temperament represents an animal’s response to situations perceived as challenging. This behavioral trait can influence numerous biological functions, primarily the stress axis, affecting production characteristics and animal welfare. A crucial aspect of temperament expression lies in how individuals perceive stressors. Molecular research has begun to elucidate the central pathways involved in the expression of temperament. Recent investigations suggest that the rumen microbiome may influence temperament, like the way that the effect of the gut microbiota on the brain in monogastric species. Further research is necessary to understand the relationship between the gut microbiome and ruminant temperament. Future applications may include modifying the temperament of production animals through the manipulation of the rumen microbiota and potentially enhancing their health and welfare.
