 In: Journal of Dairy Science v. 76, no. 6, p. 1624-163494-093226Summary: Physical structure of 14 maize silages was investigated; chewing activity was measured with eight cows over 4 d. Silages were harvested from the milk dough dent to the hard dough dent stages of maturity and chopped at lengths of 4 to 16 mm. Silages were fed for ad libitum intake and were supplemented with 2 kg of soybean meal. Eating, ruminating, and total chewing indexes varied from 16.5 to 25.3, 34.3 to 50.2, and 50.8 to 75.5 min/kg of silage DMI, respectively. Ruminating and total chewing indexes decreased as maturity stage increased. Eating index was not significantly affected by chopping to 4 to 8 mm lengths but was higher for the
