Abstract

Antibiotics were over the years, the common supplement used for poultry production. There is a global trend to lessen antibiotics’ use due to the contamination of consumed meat with antibiotic residues. Also, there is a concern that human treatments might be jeopardized due to the emergence of antibiotic-resistant bacteria. Prebiotics are attractive supplements, particularly in poultry production, because of the diversity of their effects, including pH amendments, production of short-chain fatty acids (SCFA) and the inhibition of pathogens’ growth. The commonly used prebiotics are carbohydrate sources that cannot be easily broken down by chickens. However, they can efficiently be utilized by the intestinal tract's microflora. Oligosaccharides, polysaccharides and lactose are non-digestible carbohydrate sources that are typically used in poultry diets as prebiotics. This review covers current applications and prospects for using prebiotics to improve poultry performance and reduce pathogens, particularly Salmonella, in gastrointestinal tract.

摘要

多年来，抗生素一直是家禽生产中常用的补充剂。由于食用肉类受到抗生素残留物的污染，减少抗生素的使用已成为全球趋势。此外，人们还担心人类治疗可能会因抗生素耐药细菌的出现而受到危害。益生元是有吸引力的补充剂，特别是在家禽生产中，因为它们具有多种作用，包括调节 pH 值、产生短链脂肪酸 (SCFA) 和抑制病原体生长。常用的益生元是不易被鸡分解的碳水化合物来源。然而，它们可以被肠道微生物区系有效利用。低聚糖、多糖和乳糖是不可消化的碳水化合物来源，通常在家禽饮食中用作益生元。本综述涵盖了使用益生元改善家禽生产性能并减少胃肠道病原体（特别是沙门氏菌）的当前应用和前景。
