Effects of in ovo application of resveratrol on hatchability, hatching time, yolk sac weight and chick performance in quail

Abstract

The purpose of this study was to investigate the effects of in ovo resveratrol in hatching quail eggs on hatching traits, organ weights and chick performance. The eggs were randomly distributed into four groups as non-injected group (PC; Positive control), 0.2 ml saline (NC; Negative control), 0.2 ml solution containing 1 nmol of resveratrol (R1) and 0.2 ml solution containing 4 nmol of resveratrol (R4). Hatchability of set eggs (HSE) and hatchability of fertile eggs (HFE), embryonic mortality (EM), chick hatching time, yolk sac weight (YSW), and chick performance characteristics were investigated. The effects of in ovo resveratrol administration on the HSE were insignificant. HFE decreased significantly with in ovo resveratrol treatment. All injected groups were adversely affected in terms of embryonic deaths. The effect of in ovo resveratrol application on chick hatch weight, and YSW (g, %), chick performance was insignificant. It was observed that in ovo resveratrol treatment had no significant effect on the hatching time, except at 408 h of incubation. As a result, in ovo resveratrol application had a negative effect on hatchability and EM, but did not have affected the hatching time, YSW and chick performance.
