Limiting total mixed ration (TMR) availability from 24 to 19 h/d changed the eating patterns of lactating dairy cows. Availability of ad libitum hay also made a significant difference in dry matter intake (DMI) patterns, as shown by the 95% confidence limits in the shaded bands. Rumen pH pattern throughout the day was modified in restricted-fed cows, but ranges in values were similar to those of ad libitum-fed cows. The changes in intake patterns over time indicate that when feeding TMR diets, cows can adjust to the changes in feed availability and access to long hay.

Abstract
Limiting total mixed ration (TMR) availability from 24 to 19 h/d changed the eating patterns of lactating dairy cows. Availability of ad libitum hay also made a significant difference in dry matter intake (DMI) patterns, as shown by the 95% confidence limits in the shaded bands. Rumen pH pattern throughout the day was modified in restricted-fed cows, but ranges in values were similar to those of ad libitum-fed cows. The changes in intake patterns over time indicate that when feeding TMR diets, cows can adjust to the changes in feed availability and access to long hay.| File | Dimensione | Formato | |
