Abstract
The study was conducted to determine the effect of replacing maize with graded levels of Kingzyme enzyme- supplemented burukutu waste on nutrient retention and blood profile of broiler chickens. One hundred and twenty (120) day-old Ross 308 broiler chicks were used in a completely randomized design with five dietary treatments each with three replicates. The treatments had burukutu waste replacing 0%, 25%, 50%, 75% and 100% of maize in a single phase feeding system and were labeled T1, T2, T3, T4 and T5 respectively. Treatment T1 had no Kingzyme enzyme while others had the enzyme included at manufacturer’s recommended inclusion level of 0.02%. Nutrients retention trial was carried out and haematological and serum biochemical parameters were also determined. All data collected were subjected to ANOVA and treatments means were separated using Duncan Multiple Range Test. There were no significant differences (P˃0.05) between the treatments on retention of dry matter, crude protein, ether extract and NFE. However, Kingzyme-supplemented treatments were significantly better than the control on crude fiber digestibility while no significant differences (P˃0.05) were observed among the treatments on biochemical parameters. The effects of enzyme supplemented waste were not significantly different (P˃0.05) on haematological parameters except for MCV and MCH where treatment T3 was significantly lowest than others. The eosinophil contents of birds on Treatment T2 and T4 were significantly highest. It was concluded that burukutu waste has no detrimental effect on blood profile of broilers. Kingzyme enzyme was effective in improving the utilization of burukutu waste with broiler chickens
