Feed mill challenges – what was formulated is not what the bird eats

Stark, C.

The production of broiler feed is a straight forward process that involves grinding, batching, mixing, and pelleting. However, the production of research feeds requires more effort to control processing variables that can significantly change the results of the experiment. The first variable that should be considered in the process is whether diets are formulated based on book or actual values. The next variable is particle size, the particle size of the ground grain will change growth performance. The nutrient variation from batch to batch of feeds can create differences between treatments. Finally, the percentage of fines in the feeder pan will affect feed intake/wastage.

The key to a successful research project begins with controlling these variables within the manufacturing process.
