Interaction between particle sizes of alfalfa hay and corn grain on milk yield, milk composition, chewing activity, and ruminal pH of dairy cows
Turkish Journal Of Veterinary and Animal Sciences: 1, 83-89
The objective of this study was to determine the interactions between alfalfa hay and corn grain particle sizes on nutrient intake, milk yield, milk composition, chewing activity, and ruminal pH of dairy cows. Alfalfa hay was chopped either at 4 cm (long; L) or 1 cm (short; S) theoretical length of cut. Particle size of corn grain was obtained by grinding either at 1 mm (coarse; C) or less than 1 mm (fine; F) mean particle size.
