Abstract
This study was to evaluate the effects of maize silage particle size and feeding method on dry matter intake, ruminal fermentation, chewing activity and passage rate of lactating cows. Four multiparous Holstein cows fitted with ruminal cannulas, averaging 625 kg of body weight and 195 days in milk, were assigned to a 4x4 Latin square design. The geometric mean of particle length was calculated according to Penn State Particle Separator.
