Ohio State researchers, sponsored by the US Agriculture Department, found that young crisp-fed pigs gained weight faster than pigs fed on corn, because the crisp oil fuelled the pigs with more energy.
Pork producers would see a significant reduction in their feed costs with a partial crisp diet, considering crisp scraps cost US$6 to 7.50 per tonne whilst corn is more than US$75 a tonne.
