Summary and Implications
By utilizing a Penn State feed particle separation box, consistency of feed wagon deliveries can be assessed and performance differences between pens explained in some situations. This study revealed a feed wagon that tended to unload a slightly higher level of the bulkier feed ingredients toward the end of the unloading process and thus those animals receiving the first portions tended to have a higher caloric intake per unit of ration and subsequent greater rate of weight gain because of this bias. We therefore consider it imperative to evaluate a feed wagon’s delivery characteristics prior to use in order to maintain an acceptable level of quality control in ration delivery.
