Abstract
Al-Mufarrej, S.I. and El-Sarag, M.S.A. 1997. Effects of royal jelly on the humoral antibody response and blood chemistry of chickens. J. Appl. Anim. Res., 12: 41–47.
The effects of royal jelly (RJ) on primary and secondary antibody responses against sheep red blood cells (SRBC) and on blood chemistry were studied in 40 chickens of either sex. The birds were divided into 4 equal groups A, B, C and D, each consisting of 5 male and 5 female birds. At 8 weeks of age, the birds of groups B and C were treated each with 200 mg RJ, given orally or subcutaneously, respectively. Simultaneously, both groups, as well as group A were immunized each with 0.2 ml of 10% SRBC suspension in PBS and re- immunized 10 days later with a second similar dose. Group D served as non-immunized control. Treatment witu RJ increased antibody production against SRBC in groups B and C, as compared to group A, while non-significant changes in concentrations of electrolytes and other blood constituents were recorded in the RJ-treated birds, apart from a decrease in K and cholesterol concentrations. Further studies on these lines have been recommended.
