FAST (For Active Stimulation of Tract) is an early feeding concept for one-day-old chicks developed by INVE België NV focusing on two major goals:
Highly digestible proteins, different types of carbohydrates and fibers, additives supporting the bird’s immunity and ability to digest the alimentary fat are brought together in a unique mixture of a cold-pressed granulate and a meal fraction.
FAST should be used during the first 2 days of life at 25 to 30 g/chick. Preferably, FAST is distributed on paper in the poultry house next to the feeders containing the common starter feed.
