Comparative Study Between Dietary Supplementation of Grape Pomace and Vitamin E as Antioxidant on Some Productive, Reproductive and Physiological Performance of Male and Female Aged Inshas Strain Chickens.

Abstract

This work was carried out to study the effect of dietary grape pomace and vit.E supplementation on some productive, reproductive and physiological performance traits of aged male and female Inshas strain chickens. A total number of 198 Inshas strain birds (180 laying hens and 18 cocks) 48-wks-old were used in this experiment up to 60 wks of age. All birds were individually weighed and randomly divided into 6 equal experimental groups (30 laying hens and 3 cocks of each) with three replicates (10 laying hens and 1 cock each) with nearly similar average initial live body weight of all groups. The 1 st group was fed the basal diet without supplementation but the formula of diet contained 15 mg vit.E/kg diet (control) according to NRC, (1994), while the 2 nd , 3 rd and 4 th and 5 th groups were fed on the basal diet supplemented with 1,2,3 and 4% grape pomace respectively and the 6 th group was fed the basal diet supplemented with 150 mg vit.E/ kg diet. The results showed that, values of levels 3 and 4% grape pomace were better than values of vit. E for feed conversion, egg number, egg production percentage, egg mass, plasma superoxide dismutase, plasma glutathione peroxidase and plasma testosterone and the values had significant differences (P≤0.05) for the level of 4% grape pomace only compared to vit. E group. In general, the highest level of grape pomace (T5) exhibited the best values in all semen physical characteristics, fertility and hatchability traits studied, with significant (P≤0.05) differences compared to vit. E (T6) and control (T1) groups for traits sperm motility, live sperm percentage, sperm concentration, total sperm per ejaculate, total live sperm per ejaculate, total abnormal sperm per ejaculate, fertility and hatchability percentage of both total and fertile eggs and significant (P≤0.05) differences compared to control group only in ejaculate volume and abnormal sperm percentage. On the basis of these findings, we concluded a potential use of 4% grape pomace (natural source of antioxidant) as alternative to vit. E (synthetic source of antioxidant) in diets of male and female aged birds of Inshas strain.

Effect of dietary red grape pomace on growth performance, hematology, serum biochemistry, and meat quality parameters in Hy-line Silver Brown cockerels

“…These findings are similar to those of Francesch et al [ 21 ] who demonstrated that inclusion of 50 g/kg of grape seed in the diet of Penedes chicken did not significantly affect feed intake. These results further corroborate the results by Alm El-Dein et al [ 22 ] where dietary supplementation with up to 40 g/kg grape pomace did not affect feed intake in Inshas strain chickens. This suggests that the inclusion of RGP as a functional ingredient in chicken diets does not compromise the palatability of the diets.…”

“…This suggests that the inclusion of RGP as a functional ingredient in chicken diets does not compromise the palatability of the diets. There were no significant dietary influences on overall BWG and FCR, which is consistent with the findings of Francesch et al [ 21 ] and Alm El-Dein et al [ 22 ] who reported no differences on growth performance of chickens fed grape pomace diets. Similarly, Lichovnikova et al [ 23 ] reported that the diet containing RGP did not have any significant effect on growth or FCR of broiler chickens.…”
