Effects of Grape Seed Powder on Productive Performance, Lipid Profile and Total Bacteria in Duodenum and Ceca of Broiler Chickens

Intensive broiler production exposed the birds to several stressors, such as environmental factors, crowding and vaccination. However, when free radical is higher than physiological tolerance cause oxidative stress. This study aimed to investigate the effect of supplementing different levels of grape seed powder to a broiler diet on productive performance, lipid profile and bacterial count of the duodenum and cecum. A total of ۱۸۰ unsexed one-day-old broiler chicks (Ross ۳۰۸). Birds were randomly distributed to four dietary treatments (three replicates/treatment, ۱۵ chicks/pen). T۱: (control) without addition, T۲, T۳, and T۴, (۱, ۲, ۳) % grape seed powder /kg diet, respectively. Results indicated that final body (۴۲ days of age) and accumulative weight gain, and feed conversion ratio were significantly (P<۰.۰۵) better in T۲ and T۳ (۲ and ۳) % grape seed powder/kg diet. Blood glucose concentration, cholesterol, Triglyceride, LDL, and MDA were significantly (P<۰.۰۵) decreased in T۳ and T۴ compared with other groups. While there were significant (P<۰.۰۵) increases in HDL and Glutathione peroxidase in T۳ and T۴. There was a significant (P<۰.۰۵) decrease in total aerobic bacteria and clone bacteria and a significant increase (P<۰.۰۵) in lactobacillus of duodenum and ceca for T۳ and T۴, respectively. It could be concluded from this study that adding grape seed powder at levels of (۲ and ۳) % has beneficial effects on productive performance, lipid profile and microbial count of duodenum and ceca.
