Abstract:
This experiment was conducted to evaluate the effects of different levels of sweet orange ( C itrus sinensis ) peel extract ( SOPE ) on humoral immune system responses in broiler chickens. Three hundred 1‐day broilers ( R oss‐308) were randomly allocated to treatments varying in supplemental SOPE added in the drinking water. The experimental groups consisted of three treatments fed for 42 days as follows: a control treatment without feed extract, a treatment containing 1000 ppm of SOPE and a treatment containing 1250 ppm of SOPE . All treatments were isocaloric and isonitrogenous. Broilers were vaccinated with N ewcastle disease virus ( NDV ), avian influenza ( AI ), infectious bursal disease ( IBD ) and infectious bronchitis virus ( IBV ) vaccines. Antibody titer response to sheep red blood cells ( SRBC ) was higher in the group fed 1250 ppm of SOPE ( P 〈 0.05) as well as for immunoglobulin G ( IgG ) and IgM . Similarly, antibody titer responses to all vaccines were constantly elevated ( P 〈 0.05) by SOPE enrichment in a dose‐dependent manner. Relative weights of spleen and bursa of Fabricius were unaffected by treatments. Dietary SOPE supplementation may improve the immune response and diseases resistance, indicating that it can constitute a useful additive in broiler feeding. Thus, supplying SOPE in rations may help to improve relative immune response in broiler chickens.
