Effect of Maize and Yam peels based Diets Supplemented with Xylanase, Amylase and Protease Multi-Enzymes on Serum Biochemical and Haematological Indices of Starter Broiler Chickens

Abstract

A study was conducted using one hundred and eighty (180) day old broiler chicks to determine the effect of maize and yam peels meal based diets supplemented with and without enzymes on the haematological and serum biochemical indices of broiler chickens at starter phase. Birds were allotted to six dietary treatments in a completely randomized design CRD in factorial arrangement. Two levels of enzyme (0g/kg diet and 50g/kg diet) and three levels of yam peels inclusion (0%, 15 % and 30 %) as a replacement for maize. Each treatment was replicated 3 times consisting of 10 chicks per replicate. The experiment lasted for 4 weeks. The results of serum biochemical indices revealed that Yam peels meal (YPM) inclusion and enzyme supplementation had no significant (P > 0.05) effect on all the parameters determined. The interaction effect of YPM inclusion and enzyme supplementation on serum biochemical indices showed significant differences (P< 0.05) on total protein, globulin, glucose and creatinine. Higher statistical values of total protein (3.70 g/dl and 3.85 g/dl) were obtained for birds fed 15% YPM treatment without enzyme (T2) and birds fed 0% YPM diet with enzyme supplementation (T4) respectively. The control diet significantly showed least (P < 0.05) value of total protein (2.85 g/dl). Birds fed 15% YPM diet without enzyme (T2) and 0% YPM with enzyme (T4) showed higher numerical values of 204.00 mg/dl and 203.53 mg/dl for glucose at comparative level. The result of haematological indices revealed that there significant differences (P < 0.05) in interaction for all the parameters obtained with level of YPM inclusion and enzyme supplementation. Birds fed 15% YPM diet without enzyme (T2) and 0% YPM with enzyme (T4) showed higher statistical values of 39.50% and 38.00% for PCV. Similar trend was observed for Haemoglobin, white blood cell, Red blood cell and Mean corpuscular haemoglobin. Close range values which suggested good health status were obtained for both serum biochemical and haematological indices across the treatments. In conclusion, interaction of yam peels meal with or without enzyme supplementation had significant improvement on starter broiler chickens and values recorded for haematological parameters were within the normal range for broiler chickens without adverse effect on health condition of the birds.
