Abstract
In a completely randomized design (CRD), 400 day-old Ross 308 broilers were randomly allotted to 5 diets with 0, 5, 10, 15 and 20% MSC, each with 8 replicates of 10. Weekly feed intake (FI), body weight gain (BWG) and feed conversion efficiency (FCE) were calculated whilst haemato-biochemistry was measured at d42. Overall, FI was linearly (P < 0.05) and quadratically (P < 0.01) decreased by MSC, of which the optimum inclusion was 15%, as BWG was linearly (P < 0.001) and quadratically (P < 0.05) decreased and FCE linearly decreased (P < 0.01) by MSC, of which the optimum dietary inclusion was 10%. Also, MSC linearly and quadratically decreased slaughter weight (P < 0.001 and P < 0.05, respectively), hot carcass weight (P < 0.001 and P < 0.05, respectively) and cold carcass weight (P < 0.001 and P < 0.05, respectively). Similarly, it linearly decreased white blood cells (P < 0.01) and lymphocytes (P < 0.05) as it linearly (P < 0.001) and quadratically (P < 0.01) decreased symmetric dimethylarginine (SDMA) and linearly (P < 0.001) increased serum cholesterol. In conclusion, up to 10% MSC can be incorporated into broiler diets in replacement of SBM without adverse effects.
