摘要

球虫病是家禽业面临的主要挑战之一,导致动物生产性能和福利下降,死亡率上升。目前,离子载体和化学物质被用于治疗球虫病。然而,耐药艾美耳球虫菌株的爆发和客户对更可持续产品的需求日益增长,促使有必要确定球虫病控制的营养策略。在这项研究中,我们通过一项基于5项独立试验的荟萃分析,回顾了在球虫病肉鸡中添加功能性氨基酸(精氨酸、苏氨酸和谷氨酰胺)和葡萄提取物多酚的效率。我们观察到,与感染、未治疗的肉鸡相比,添加球虫饲料部分改善了感染球虫病肉鸡的生产性能。此外,在整个试验期内,添加功能氨基酸与葡萄提取物多酚组合对动物生产性能的影响与添加抗球虫药物无显著差异。本荟萃分析表明,在球虫病肉鸡中添加功能氨基酸和葡萄提取物多酚可以提高肉鸡生产性能。然而,需要进一步的研究来了解所涉及的机制。

A combination of functional amino acids and polyphenols can restore the performance of chickens challenged with coccidiosis: A meta-analysis

Coccidiosis is one of the major challenges in the poultry industry, leading to reduced animal performance and welfare and increased mortality. Currently, ionophores and chemicals are used to treat coccidiosis. However, the outbreak of resistant Eimeria strains and the growing customer demand for more sustainable products have prompted the need to identify nutritional strategies for coccidiosis control. In this study, we reviewed the efficiency of the supplementation of a combination of functional amino acids (arginine, threonine and glutamine) with grape extract polyphenols in broilers challenged with coccidiosis via a meta-analysis based on five independent trials. We observed that supplementation partially improved the performance of broilers affected with coccidiosis when compared with infected, untreated animals. In addition, there was no significant difference between the effect of supplementation of the combination of functional amino acids with grape extract polyphenols and that of anticoccidial drugs on animal performance when considering the overall trial period. This meta-analysis suggests that supplementing with a combination of functional amino acids with grape extract polyphenols could improve performance in broilers affected with coccidiosis. However, further research to understand the mechanisms involved is needed.
