Exogenous enzymes have increased in popularity over the past two decades, becoming an important feature in the diets of monogastric animals in the United States and Europe. In this episode, I interviewed Tanner Wise, a PhD candidate at Purdue University's Animal Sciences Department. We talked about some categories of enzymes, like phytase, cellulase, xylanases, and beta glucanases, and their roles in animal performance, as well as in return on investment. Also, we discussed how conditioning temperature is a critical consideration for feed mills in maintaining the stability of enzymes under commercial conditions, and how there are more heat-stable versions of enzymes emerging, supporting the viability of their application."Using higher conditioning temperatures can negatively impact bird performance and nutrient digestibility. However, research suggests we can increase the temperature slightly past 70-76°C up to 80°C, where we really see that jump in pellet quality, while still maintaining adequate performance."
