Use of exogenous enzymes for poultry: A critical view

Abstract

The search for alternatives that enable the reduction of production costs, especially in the poultry industry goes against the performance of products such as exogenous enzymes. However, efficient use of such products depends on meaningfull and concrete results on its potential benefits. Thus, much research has been conducted in attempt to elucidate the enzymes potential on improving the digestibility of ingredients and consequently on the performance of birds. Until then, the results presented, especially about the group of enzymes understood by carbohydrases and proteases are still very contradictory. Several methods and surface analysis adopted by researchers led to a series of inaccurate and biased conclusions. It is necessary to adopt specific assessments that glimpse the pratical potential and enzymes objective concerned to raw materials used in Brazil, aiming to achieve clear and timely results.
