A simple apparatus for counting the number of chewings in cattle was developed to count the daily total chewing number during the eating and ruminating processes. It was possible to count the number of chewings continuously for more than 2 months without any difficulty. The daily total chewing number or time spent chewing was estimated accurately by only reading the number once a day. When four heifers were fed a constant amount of hay for 3 weeks, the coefficients of variance of the chewing counts for days and animals were 7.3 and 8.8%, respectively. Temporary increase of intake affected the chewing counts for more than 4 days after the feeding.
