Effect of Grape Procyanidins on Growth Performance and Immune Function in Broilers
摘要
Abstract
This experiment was conducted to investigate the effects of dietary grape procyanidins on growth performance and immune function in broiler chickens. Two hundred and forty day-old Arbor Acre male broiler chickens were randomly allotted into four dietary treatments with different inclusion ( 0,7. 5,15 or 22. 5 mg/kg) of grape procyanidins. The experiment period lasted for 6 weeks. The results showed that chicks fed higher dose of grape procyanidins intake more feed and grew faster during the first 3 weeks. During the second 3 weeks and the whole 6 weeks,chicks fed 7. 5 mg/kg grape procyanidins had higher body weight gain and superior feed efficiency,and chicks fed 15 mg/kg grape procyanidins diet had inferior growth performance compared to the controls. Dietary grape procyanidins did not affect the growth of the immune organs. The percentages of CD3+ ,CD4+ ,CD8+ , aJ3 and y8 T lymphocytes in peripheral blood had the increased tendency in chicks fed 7. 5 mg/kg grape procyanidins. Overall,optimal dose of grape procyanidins in the diet would stimulate late growth and modulate immune function in broiler chickens.关键词
