The objective of this study was to evaluate the effects of bee pollen (BP) and propolis (PRO) supplementation on rabbits' productive performance and serum metabolites through a meta-analysis. Sixteen peer-reviewed publications were included in the data set. The rabbit strains used in the studies included in the data set were New Zealand White, V-line, Rex, and V-line crosses. Weighted mean differences (WMD) between treatments supplemented with BP or PRO and control treatments were used to assess the magnitude of the effect. BP supplementation decreased ( < 0.001) daily feed intake (DFI) and feed conversion ratio (FCR); however, increased ( < 0.001) average daily gain (ADG) and hot carcass yield (HCY). PRO supplementation reduced DFI ( = 0.041) and FCR ( < 0.001), and increased ADG ( < 0.001) and HCY ( = 0.005). In blood serum, BP supplementation increased total antioxidant capacity (TAC; = 0.002) and decreased serum creatinine concentration ( = 0.049). Likewise, decreased serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and malondialdehyde (MDA) were detected in response to BP supplementation ( < 0.05). PRO supplementation increased the TAC in blood serum ( = 0.018); however, decreased serum concentrations of AST, ALT, and MDA were observed ( < 0.05). In conclusion, BP or PRO supplementation can be used as a natural growth promoter in rabbits, and both can also improve rabbits' antioxidant status. However, BP or PRO supplementation does not affect rabbits' renal or hepatic health status.
本研究的目的是通过荟萃分析评估补充蜂花粉（BP）和蜂胶（PRO）对家兔生产性能和血清代谢产物的影响。数据集中纳入了16篇经同行评审的出版物。数据集中纳入研究的家兔品种包括新西兰白兔、V系兔、獭兔和V系杂交兔。采用补充BP或PRO的处理组与对照组之间的加权平均差（WMD）来评估效应大小。补充BP可降低（<0.001）日采食量（DFI）和饲料转化率（FCR）；然而，可提高（<0.001）平均日增重（ADG）和热胴体产量（HCY）。补充PRO可降低DFI（=0.041）和FCR（<0.001），并提高ADG（<0.001）和HCY（=0.005）。在血清中，补充BP可提高总抗氧化能力（TAC；=0.002）并降低血清肌酐浓度（=0.049）。同样，补充BP后检测到血清天冬氨酸转氨酶（AST）、丙氨酸转氨酶（ALT）和丙二醛（MDA）水平降低（<0.05）。补充PRO可提高血清中的TAC（=0.018）；然而，观察到血清AST、ALT和MDA浓度降低（<0.05）。总之，补充BP或PRO可作为家兔的天然生长促进剂，二者还均可改善家兔的抗氧化状态。然而，补充BP或PRO不影响家兔的肾脏或肝脏健康状况。
