Carbohydrase enzymes may increase the nutrient
availability of carbohydrates bound in nonstarch polysaccharide
fractions (Jones et al., 2010). Commercially
available carbohydrase enzymes have been developed
and are most effective in diets that contain ingredients
with higher nonstarch polysaccharide concentrations
than would be found in corn (Omogbenigun et al.,
2004). The effectiveness of commercial carbohydrase
enzymes has been inconsistent in corn–soybean meal–
based swine diets; however, the increased substrate of
nonstarch polysaccharides in drought-affected corn
may provide an economic model for enzyme inclusion
(Dänicke et al., 1999). The objective of this research
was to determine the effects of drought-affected corn
inclusion with or without supplementation of commercial
carbohydrases on growth performance and
nutrient digestibility of nursery pigs.
