The use of antibiotics as growth promoters or for the prevention of some poultry diseases has faced global concern and serious criticism. Their addition to poultry feed has shown hazardous effects, including the development of antimicrobial resistance and a potentially harmful effect on human health. To eliminate these threats, there is increasing interest in natural alternatives. Plant derivatives such as garlic ( L.) and its derivatives are presently extensively used in the poultry production system. The dietary supplementation of broilers and layers with garlic induced improvement in the production parameters, carcass quality, and intestinal integrity. The modulation of the immune response against some important viral diseases has resulted from the supplementation of poultry with garlic. Moreover, garlic has been shown to modulate gut health through antibacterial and antiparasitic activities. Treatment with garlic can also mitigate oxidative stress and reduce free-radical production. The reduction of cholesterol levels and improvement of some liver and blood parameters were also reported following the dietary inoculation of garlic. This review was designed to investigate the influence of garlic as a dietary additive on the performance, immunity, gut health, anti-oxidant status, blood parameters, and intestinal microbiota of poultry.
将抗生素用作生长促进剂或用于预防某些家禽疾病已面临全球关注和严厉批评。在禽饲料中添加抗生素已显示出有害影响，包括产生抗菌抗性以及对人类健康可能产生有害影响。为消除这些威胁，人们对天然替代品的兴趣与日俱增。诸如大蒜及其衍生物等植物提取物目前在禽类生产系统中被广泛使用。在肉鸡和蛋鸡日粮中添加大蒜可改善生产性能参数、胴体品质和肠道完整性。在家禽日粮中添加大蒜可调节针对某些重要病毒性疾病的免疫反应。此外，大蒜已被证明可通过抗菌和抗寄生虫活性调节肠道健康。用大蒜处理还可减轻氧化应激并减少自由基产生。日粮添加大蒜后，胆固醇水平降低以及一些肝脏和血液参数得到改善的情况也有报道。本综述旨在研究大蒜作为日粮添加剂对家禽的生产性能、免疫力、肠道健康、抗氧化状态、血液参数和肠道微生物群的影响。
