PERFORMANCE AND SERUM METABOLITES OF BROILER CHICKS FED HULLED SUNFLOWER SEED CAKE DIETS

C. A. Adeniji, B. K. Ogunmodede

Abstract


The replacement value of hulled—sunflower seed cake protein (HSFCP) at 0,25.50,75 and 100% for soybean cake protein (SBCP) was assessed using 225 day-old broiler chickens.  The diets were isonitrogenous and isocaloric with 23 and 20% crude protein as well as 2.95 kcal/g and 2.85 kcal/g metabolisable energy at the starter and finisher phases respectively.  At the starter phase highest (P< 0.05) live weight of 625.00g, protein efficiency ratio of 1.63 and 2.92 mg/dl creatinine concentration were obtained with 25% HSFSCP and poorest feed efficiency ratio of 3.65 and 51.30 mg/dl of urea were obtained with 100% HSFSCP, while highest glucose concentration of 30.96 which did not significantly differ (P> 0.05) from value obtained with 75% HSFSCP was obtained with 50% HSFSCP diet.  At the finisher phase HSFSCP reduced (P< 0.05) nitrogen and either extract retentions, lowest values of 54.71 and 96.94% were obtained with 100% and 50% HSFSCP respectively.  Creatinine and glucose concentrations were increased (P< 0.05) except for 3.37 mg/dl with 75% and 120.20 mg/100ml for 0% respectively, which did not differ (P> 0.05) from value obtained with 25%.  At the overall (starter and finisher) live weight, feed and protein utilizations of 75% did not differ (P>0.05) from values obtained with 0% HSFSCP.  This study suggested that for efficient growth and protein utilization HSFSCP could replace 75% of SBCP in broiler chicken diets.
