RESUMO
ABSTRACT The purpose of this study was to determine the effects of in-ovo injection of a propolis water extract on hatchability, embryonic mortality, starter live performance, and livability of Japanese quails. In total, 500 fresh hatching eggs were randomly distributed into five treatment groups of 100 eggs per treatment with four replicates of 25 eggs each. On day 14 of incubation, eggs from group 1 were not injected (control), group 2 was injected with distilled water (water), group 3 was injected with 1% propolis water extract (1% propolis), group 4 was injected with 2% propolis water extract (2% propolis), and group 5 was injected with 3% propolis water extract (3% propolis). A completely randomized design was applied, and data were analyzed using the least-square methodology. Hatchability and embryonic mortality in the 2% propolis and 3% propolis treatment groups were significantly lower compared with the control group, but no significant differences were observed between the 1% propolis and control groups. There were no significant bodyweight gain, feed intake, feed conversion ratio, or livability differences among treatments. The results of this study demonstrated that in-ovo injection of propolis water extract, especially at doses of 2% and 3% propolis, had negative effects on hatchability and embryonic mortality, but 1% propolis had no detrimental effects on hatchability or embryonic mortality. In all treatment groups, propolis did not negatively affect body weight gain, feed intake, feed conversion ratio, or livability.
