Physical quality of feed is practically assessed by the size of the feed particles actually presented to the
birds. It is often difficult to assess this on the farm, where subjective opinions can lead to a poor description
of feed texture. Aviagen has developed a method to measure feed quality using a shaker sieve device which
quantifies the particle size distribution of feed in a straight-forward and easily observable manner. Using this
approach also allows a quantitative comparison to be done between feed deliveries or flocks at the farm
level.
