Abstract

The objective, through a systematic review, was to identify the potential of propolis as a food additive that modulate rumen fermentation and promoting growth in ruminants. The systematic review was conducted according to the protocol described in PRISMA and was carried out by collecting published data on propolis as a modulator of ruminal fermentation, a growth-promoting additive between 2000 and 2023. Selected works had to meet three factors, considered mandatory as inclusion criteria: 1) study the effect of propolis on the modulation of ruminal fermentation and/or 2) the effect of propolis on the performance or carcass quality of beef animals 3) No be a review article. In the end, 39 articles were selected for analysis and synthesis in the systematic review. The results demonstrate that there are positive effects of brown, green and red propolis on the modulation of ruminal fermentation and this influences the growth of ruminants. A large variation in responses to propolis was evidenced, probably due to differences in the composition or concentration of phenolic compounds tested, which demonstrated the need for standardization of studies. The residue from propolis extraction was also able to modulate ruminal fermentation and deserves further studies, mainly because it is a cheaper alternative than the extract.
