“…Abdo et al (2010) determined that green tea leaves (1.0%, 3.0%, and 5.0% of the diet) and green tea extracts (0.5, 1.5, and 2.5 L/100 kg of the diet) to diet (specifically green tea extracts) reduced egg pH levels of stored egg until 12 days. Moreover, other researchers stated that pH value of breast meat (Pectoralis major) reduced in 0.1% green tea extract (content 13.93% total catechin) supplementation to broiler diet (Erener et al 2011). The egg pH values were not affected in our study, which could be attributed to egg storage duration and inserting catechin levels.…”

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

“…In contrast to the above findings, in our study the amount of small intestinal digesta was lower in turkeys fed diet with the highest content of HT FB than in birds fed diet with the lowest content of HT seeds. Such an effect can be explained by the results of previous experiments where the relative length of the small intestine and caeca decreased in chickens fed diets supplemented with polyphenol-rich extracts (Erener et al, 2011).…”

One-day-old female turkeys were randomly assigned to five dietary treatments and were fed for 15 weeks diets containing 5% of cellulose (control, C) or 5% of dried fruit pomaces (apple, black currant, strawberry, seedless strawberry; AP, BCP, SP, SSP respectively). In weeks 11-15 of feeding, all diets were supplemented with 2.5% of linseed oil. The crude fibre content of fruit pomaces ranged from 56.5% in AP to 62.9% in SP. In comparison with AP, berry fruit pomaces (BCP, SP and SSP) were characterised by a higher content of neutral detergent fibre - NDF (41.2% vs. 52.7-59.3%) and lignin (13.24% vs. 21.80-25.56%). A monomer analysis revealed that cellulose was the main non-starch polysaccharide (NSP) in fruit pomaces, whereas their pectin content was low. Polyphenol content was determined at below 6 g/kg in AP, at approximately 12 g/kg in BCP and SP, and at 32.8 g/kg in SSP. There were no significant differences (p > 0.05) in final body weight of birds. After 15 weeks of feeding fruit pomaces to turkeys, the relative weight of the small intestine with digesta was higher in group AP, and lower in group SSP, as compared to controls. Dietary fruit pomaces decreased the dry matter (DM) concentration and lowered the pH of the small intestinal digesta, except the AP and SSP treatments respectively. In the caeca, significantly reduced concentrations of ammonia or putrefactive short-chain fatty acids (SCFA) upon dietary fruit pomaces were observed. Fruit pomaces did not influence the concentrations or the total pool of short-chain fatty acids, but led to a significant increase in butyric proportion in the SCFA profile at the expense propionate.
