| Abstract | ||
| An experiment was designed on 165 local Sinai laying hens (150 females + 15 males), 47 wk-old, were equally divided into five dietary treatments to determine possible benefits from dietary supplementation with proanthocyanidins to the layer's diet of grape pomace and green tea extracts (GPGT extract) at levels (0, 50, 100, 150 and 200 mg/kg diet) on productive and reproductive performance during the laying period from 47 to 62 wk of age. Results illustrated that egg number/hen or laying rate (%) significantly (P≤0.05) improved due to feeding the diet supplemented with 150 mg GPGT extract/ kg diet as compared to the control group. Also, the hens fed diet supplemented with 150 mg GPGT extract recorded the highest value of egg mass when comparing with the control and other dietary treatments. Fertility % of eggs from hens fed diet supplemented with 100 and 200 mg GPGT extract / kg diet was significantly (P≤0.05) increased compared to the low level of extraction (50 mg/ kg diet) and control diet. The diet supplemented with 100 mg GPGT extract / kg diet had higher hatchability % and chick weight than the control diet. In addition, total antioxidant capacity yolk content in was significantly increased as a result of feeding on diet with 150 mg GPGT extract/ kg diet compared to the control diet. It could be concluded that supplementation 150 mg GPGT extract / kg diet in Sinai hen's diets can be used to maximize the egg production performance, quality of egg yolk and economic efficiency from 47 to 62 wk of age. Moreover, these results suggest that 100 mg GPGT extract/ kg layer diet can be applied for optimal performance of reproductive traits. | ||
