Rethink carbohydrases, productdevelopment effect in monogastrics

摘要

DEVELOPMENTAL progress in science depends on the construction and deconstruction of hypotheses and applies to all scientific fields, including animal science.One hypothesis recently called into question is what is responsible for the performance effect of carbohydrases in monogastric animals. This has always been explained by three hypotheses:1. Reduction of viscosity In the gastrointestinal (GI) tract;2. Provision of prebiotics, and3. Reduction of the cell wall effect.Although broadly accepted in the scientific community, these hypotheses have scarcely been proved in research. The most controversial is that carbohydrases open the cell wall of ingredients and allow endogenous enzymes to hydrolyze the nutrients inside,whichare otherwise trapped and excreted through the feces.
