Microbiota of broilers fed low and high protein diets supplemented with proteases and their effects on body weight.

In recent years feed additive enzymes have gained great popularity and some enzymes such as phytase have become as common as corn or soybean meal in poultry diets. The potential of using feed enzymes has drawn much interest to the development and use of other enzymes with our current interest focused towards proteases. The objective of this study was to evaluate the potential of the addition of proteases in diets of broilers feeding with diets low and high-level protein based on performance and microbiota cecal.
