Abstract
Growth, apparent nutrient digestibility, ileal digesta viscosity, and energy metabolizability of growing turkeys fed diets containing malted sorghum sprouts (MSP) supplemented with enzyme or yeast were investigated using 120, 28-day-old male turkeys. Six treatments were laid out in a 392 factorial arrangement of treatments with three dietary inclusion levels of MSP (0, 50, and 100 g/kg) and supplemented with 200 mg/kg yeast (Saccharomyces cerevisiae) or 200 mg/kg of a commercial enzyme. The experiment lasted for the starter (day 28–56) and grower phases (day 57–84) of the birds. Each treatment group consisted of 20 turkeys replicated four times with five birds each. Data were analysed using analysis of variance while polynomial contrast was used to determine the trends (linear and quadratic) of MSP inclusion levels. Irrespective of dietary supplementation with enzyme or yeast, final body weight (BW), total BW gain, and feed intake for turkey poults from day 29–56 was reduced (p< 0.05) with increasing inclusion level of MSP. Dietary supplementation with yeast resulted in increased (p< 0.05) feed intake while enzyme supplementation improved (p <0.05) feed conversion ratio of the poults. Turkeys fed enzyme-supplemented MSP diets had higher (p<0.05) BW gain than their counterparts fed yeast-supplemented MSP diets. Apparent ash digestibility reduced linearly (p<0.05) with increasing inclusion levels of MSP. Apparent metabolizable energy (AME) did not vary significantly (p>0.05) with MSP inclusion levels.Enzyme supplementation reduced (p< 0.05) ileal viscosity but had no effect (p>0.05) on AME. Inclusion of MSP resulted in poor growth performance. This confirms earlier studies that utilization of MSP by poultry is rather poor. Supplementation with enzyme or yeast did not lead to any appreciable improvement in performance of turkeys in this study.
