N: number of studies; NC: number of comparisons; SD: standard deviation; WMD: weighted mean differences between control and treatments supplemented with bee pollen; CI: confidence interval of SMD; p-Value for the χ2 test of heterogeneity; I2: proportion of total variation of size effect estimates that is due to heterogeneity; 1: Egger’s regression asymmetry test; ADG: average daily gain; DFI: daily feed intake; FCR: feed conversion ratio; HCY: hot carcass yield.
