Effect of Feeding Fermented Rapeseed meal on the Serum Biochemical Constituents and Immune Response of Commercial Broiler Chicken

The study evaluated the impact of raw and fermented rapeseed meal (RSM and FRSM) on serum biochemical parameters and immune response of commercial broiler chicken. Experiment was conducted on day old chicks for 42 days and birds were allotted randomly. Dietary treatments consisted of a control standard corn-soya bean meal diet and 6 test diets where raw or fermented rapeseed meal included at 5, 10 and 15% levels. Blood samples taken at day/ 37 measured total protein, albumin, globulin, creatinine, aspartate amino transferase (AST), alanine transaminase (ALT), and New castle Disease antibody titer, while cell-mediated immunity was assessed via a phyto haemagglutinin phosphate (PHA-P)induced skin response on day/ 40. Results showed no effects on albumin, globulin, creatinine, or AST/ALT ratio across treatments. However, total protein was significantly higher in the 10% FRSM group (P<0.05), with other groups comparable to the control. Neither antibody titers nor cellular immunity were affected by the inclusion of RSM or FRSM at any level. The study concludes that incorporating up to 15% of either raw or fermented rapeseed meal in broiler diets has no adverse effect on serum biochemical parameters or immune responses, making these feed components safe for commercial use.
