Profitable production of rabbit meat requires comfortable environment for expression of good quality traits embedded in the genetic components of rabbits. One of the major problems facing rabbit production is heat stress, especially in hot regions of the world. This is further aggravated by global warming being experienced as a result of climate change. Rabbits have no or few sweat glands, complicating the problem of heat dissipation, thereby predisposing the animals to heat stress (HS). Heat stress adversely affect welfare and adaptation, feed consumption and utilization, immunity and health status, growth, reproduction, and milk production in rabbits. Rabbits are homoeothermic animals. They should be capable of body temperature regulation within a narrow range. Thermoregulation is extremely poor in rabbits because of lack of sweat glands. Rabbits are highly sensitive to high ambient temperature. The presence of thick insulator fur on the skin further impedes heat loss in rabbits. This review summarizes data available literatures in the last two decades (2000–2020). Short compilation on management techniques adopted in rearing rabbits under hot conditions is included.

兔子的环境热应激:影响和改善

兔肉的盈利生产需要舒适的环境来表达嵌入兔子遗传成分中的优质性状。兔子生产面临的主要问题之一是热应激,尤其是在世界炎热地区。气候变化导致全球变暖进一步加剧了这种情况。兔子没有汗腺或汗腺很少,使散热问题复杂化,从而使动物易患热应激 (HS)。热应激会对兔子的福利和适应、饲料消耗和利用、免疫和健康状况、生长、繁殖和产奶量产生不利影响。兔子是恒温动物。它们应该能够在窄范围内调节体温。由于缺乏汗腺,兔子的体温调节非常差。兔子对高环境温度高度敏感。皮肤上厚厚的绝缘毛皮的存在进一步阻碍了兔子的热量散失。本综述总结了过去二十年(2000-2020 年)的可用文献数据。包括在炎热条件下饲养兔子所采用的管理技术的简短汇编。
