- ... The objective of this study was to evaluate the effect of feeding regimen on chewing activity and ruminal passage of digesta in non-lactating cows fed pasture ad libitum. Six ruminally fistulated Holstein dry cows (mean±SD; parity=3.7±0.5, length of pregnancy=28±2 W, BW=692±75 kg) were assigned randomly to two dietary treatments using a crossover design; three cows were rotationally grazed pasture ...
