Heat stress has become a widespread concern worldwide, which is a major environmental stress that causes substantial economic loss in the rabbit industry. Compared to other agricultural animals, rabbits are more sensitive to heat stress as they have fewer sweat glands and a thicker coat of fur, increasing the heat dissipation complexity. Thus, heat stress hurts rabbits' productivity, meat quality, reproductive performance, antioxidative properties, immune responsiveness, intestinal histomorphology, and microbiome. Nutraceuticals include vitamins, minerals, antioxidants, organic acids, fatty acids, probiotics, prebiotics, synbiotics, enzymes, and medicinal plants due to the possible impacts on maintaining common biological situations, strengthening immune response, and preventing illness, which ultimately led to an increase in productivity. Nutraceuticals have recently attracted a lot of attention to alleviate the adverse impacts of heat stress in rabbit farms. The objective of the current review is to provide acquaintance with the recent findings about the impact of heat stress on rabbit productivity and the advantages of dietary supplementation of nutraceuticals in mitigating it.
热应激已成为全球广泛关注的问题，它是一种主要的环境应激因素，给养兔业造成了巨大的经济损失。与其他家畜相比，兔子对热应激更为敏感，因为它们的汗腺较少且皮毛较厚，这增加了散热的复杂性。因此，热应激会损害兔子的生产性能、肉质、繁殖性能、抗氧化特性、免疫反应、肠道组织形态和微生物群。营养保健品包括维生素、矿物质、抗氧化剂、有机酸、脂肪酸、益生菌、益生元、合生元、酶和药用植物，因为它们可能对维持正常生理状态、增强免疫反应和预防疾病产生影响，最终提高生产力。最近，营养保健品在减轻兔场热应激的不利影响方面引起了广泛关注。本综述的目的是让读者了解热应激对兔子生产性能的影响以及日粮添加营养保健品在减轻热应激方面的优势的最新研究结果。
