Dietary Supplementation of Grape (Vitis vinifera) Seed Powder in Broiler Chicken

The experiment was carried out to study the effect of dietary supplementation of grape seed powder (GSP) in broiler chicken. A total of 240 straight-run day-old commercial broiler chicks were randomly distributed to four groups viz. A, B, C and D and supplemented with GSP @ 0, 5, 10 and 15g/kg feed, respectively. The supplementation of grape seed powder @ 5, 10 and 15 g/kg feed did not affect body weight, weight gain and feed intake and carcass parameters. Grape seed powder @ 5g/kg diet was beneficial to improve feed efficiency in broilers. Graded levels of grape seed powder (5, 10, and 15g/kg feed) significantly (P < .05) increased serum total protein and albumin level in broilers without affecting serum globulins. Grape seed powder @ 10, and 15g/kg feed helps to maintain liver health and improve antioxidant capacity in terms of serum SOD activity. The GSP levels did not influence ileal Escherichia coli count but improved the count of beneficial Lactobacillus spp. The GSP @ 5g/kg diet was economically beneficial to increase the net profit in broilers. In conclusion, it is recommended to use grape seed powder @ 5g/kg of feed in broiler diet for improving feed efficiency, gut health and net profit without altering growth and carcass parameters.
