Different technique in feed production may lead to different particle sizes and varia- tion. The overall target for mash feed struc- ture needs to be optimal homogeneity. Mash feed with “some finer” or “some coars- er” structure will be optimal as well, as long the structure ensures optimal homogene- ity. Variation in feed structure from batch to batch and within different feed deliveries should be as low as possible. A minimum amount of added fat and/or oil supports homogeneity and palatability of mash feed in the rearing and laying phase.
