Background:

Ruminants consume pasture and forages, but occasionally they do not have the necessary capacity for this, affecting digestibility. One of the strategies to improve quality is the utilization of exogenous enzymes that break down the structure of the cell wall, and permit better nutrient intake.

Aim.

To conduct a comprehensive study on the action mechanisms of exogenous fibrolytic enzymes in ruminant nutrition.

Development:

Plant cell wall is made of cellulose, hemicellulose, and lignin. The cellulases, hemicellulases, and lignocellulolytic enzymes are engaged in their degradation, being used satisfactorily in the diet to enhance digestibility with positive effects on other species’ production.

Conclusions

This practice favors greater nutrient availability for digestion and absorption, and it contributes to the improvement of physiological processes, and on many occasions, it is evidenced through livestock yield increases.
