DuPont webinar: Calcium, the double edged sword


In poultry and pig diet formulation, calcium (Ca) is a necessary ingredient. In recent years, it has become clear that too much Ca or the wrong particle size can be detrimental for digestion. Therefore, Ca is a double edged sword

In short – We need to go back to the fundamentals of Calcium: how it responds to the conditions in the gut and how it interacts with other essential nutrients. Things are even more inextricably connected than previously thought; making the right choices for correct diet formulation and optimal performance of the animals depends on more factors than is often assumed.

Now which factors should we consider exactly? To enlighten and update our viewers on this matter, All About Feed in cooperation with DuPont will host a webinar on calcium with practical recommendations to be incorporated in feed formulation. The webinar, featuring 2 expert speakers, will be broadcasted live from Amsterdam, the Netherlands, on December 6, 10am Central European Time (CET).
