Mastication and maturity: a longitudinal study in pigs.
The electromyography of mastication was studied longitudinally in miniature pigs, and the effects of age and food type were assessed. Within-individual variation was large relative to between-individual variation. Duration of chewing strokes increased with age and with more resistant foods. The results are compared with data on human beings and other animals.
