Considerations on the Use of Exogenous Fibrolytic Enzymes to Improve Forage Utilization

Digestion of cell wall fractions of forage in the rumen is incomplete due to the complex links which limit their degradation. It is therefore necessary to find options to optimize the use of forages in ruminant production systems. One alternative is to use exogenous enzymes. Exogenous fibrolytic enzymes are of fungal or bacterial origin and increase nutrient availability from the cell wall, whi...

Use of exogenous fibrolytic enzymes to enhance in vitro fermentation of alfalfa hay and corn silage.

Two in vitro experiments were performed to identify promising exogenous fibrolytic enzyme products (EFE) and optimum dose rates (DR) for improving the degradation of alfalfa hay and corn silage. The relationship between enzymatic activity and fermentation responses was examined to identify optimum formulations. In experiment 1, 5 EFE containing mainly endoglucanase and xylanase activities, with...

In vitro Effects of Exogenous Fibrolytic Enzymes on Rumen Fermentation of Wild Guinea Grass (Panicum maximum)

This study aimed to evaluate the potential of commercial enzymes cellulase (CE), xylanase (XY) and the combination of CE + XY to improve rumen fermentation of Guinea grass ecotype ‘A’ (Panicum maximum). The experiment was carried out in a randomized complete block design. In vitro incubations were performed with four doses of individual enzymes and their combinations (1:1 from each enzyme) as 5...

Improving Forage Quality and Animal Performance with Fibrolytic Enzymes

Enzymes have been used for decades to improve the utilization of swine and poultry diets. For instance phytase, amylase, ß-glucanase and xylanase are added to the cereal-based diets of such monogastrics to increase the utilization of dietary phosphorous, starch, ß-glucans and arabinoxylans respectively. For many years, researchers were discouraged from using enzymes to enhance the utilization o...
