Efficacy of supplementary enzymes on in vitro digestibility of various ratios of maize with wheat offal
Keywords:
Efficacy, fungal, bacterial, enzyme, digestibilityAbstract
The basic experimental diets were 4 x 5 factorial combinations of the inclusion levels of wheat offal at the expense of maize in the control diet with different enzymes. Basically the control diet had 100% of maize while in other diets 25, 50, 75 or 100% of maize was replaced with wheat offal. Each of these was replicated thrice and undertaken in the presence of no enzyme, with different types of enzymes at the recommended level or a combination of different types of enzymes. Thus were a total of 60 treatment samples and then the in vitro digestibility trial was carried out. The results showed that increase in the level of wheat offal at the expense of maize without enzyme supplementation caused significant decrease in nutrient digestibility (P<0.05). However, inclusion of fungal or bacterial enzyme and their combinations improved nutrient digestibilities in vitro (P< 0.05).
