“…The egg albumen includes bicarbonates and carbon dioxide, and the loss of dissolved carbon dioxide results in the increase in the pH of albumen. Prospective decreasing in egg pH, particularly in the albumen, degrades the proteins and then decreasing albumen quality (Tona 2013). In this study, the albumen pH and yolk pH of eggs which were stored for a week and two weeks at + 4°C were not affected by catechins, only decreased as numerically.…”

The aim of this study was to investigate the effect of green tea (Camellia sinensis) catechin addition to breeder quail (Coturnix coturnix japonica) diet on productivity, reproductive performance, egg quality and yolk malondialdehyde (MDA) levels during storage, and some serum biochemical parameters. In this study, a total number of 180 quail, 7 weeks of age were randomly divided into 3 groups (1 control group and 2 treatment groups) with 5 replicates (9 females + 3 males). The control group was fed basal diet; the treatment groups were fed basal diet with 0.2% and 0.4% catechin supplementation for 5 weeks. The results of this study showed that 0.2% and 0.4% catechin addition had no significant effects on live weight, feed intake, egg production, feed efficiency, and egg internal quality (yolk colour, albumen index, yolk index, Haugh units, and pH) (P > .05). Catechin addition reduced egg weight, egg specific gravity, and egg shell thickness (P < .001). The catechin addition to diet significantly diminished MDA concentrations of eggs (P < .05). Serum glucose and triglyceride levels significantly decreased (P < .05) in the 0.4% catechin group, but were not significantly affected (P > .05) in the 0.2% catechin group compared to the control group. The addition of 0.2% catechin significantly increased fertility (P < .05), hatchability (P < .01), and the hatchability of fertile eggs (P < .05). In conclusion, catechin supplementation to breeder quail diet has the potential to increase egg shelf-life and reproductive performance. On the other hand, supplementation with these catechin levels decreased egg weight and egg shell quality. ARTICLE HISTORY

“…The present study also involves preliminary results on the Japanese quail eggs response to non-destructive impact during their storage. This research was inspired by the paper (Tona et al, 2013) where the resonant frequency of the hen eggs was evaluated. It was shown that this parameter could be used for the eggs quality description during their storage.…”
