Summary

Rumination time (RT) significantly decreases in the final 6 hours before calving in dairy cows. This reduction, along with decreased feeding time and dry matter intake (DMI), may help predict calving timing.

Area of Science:

  • Animal Science
  • Dairy Science
  • Reproductive Biology

Background:

  • Feeding behavior monitoring is crucial for dairy cow health and management.
  • Understanding prepartum behavioral changes can aid in predicting calving events.
  • Rumination time (RT), feeding time, and dry matter intake (DMI) are key indicators of cow welfare.

Purpose of the Study:

  • To investigate the effect of calving onset on rumination time (RT).
  • To examine the relationship between feeding time, dry matter intake (DMI), and calving onset.
  • To evaluate correlations between RT, feeding time, and DMI as feeding behavior characteristics.

Main Methods:

  • Continuous monitoring of RT using electromyography-based halter (DairyCheck).
  • Recording feeding time and DMI via automatic feed bins.
  • Analyzing feeding behavior data from 17 pregnant Holstein cows in the final 72 hours prepartum.

Main Results:

  • RT significantly decreased by 27% in the final 6 hours before calving compared to the reference period.
  • Feeding time and DMI also showed significant reductions of 57% and 56%, respectively.
  • High correlation was observed only between feeding time and DMI; RT variability was high among cows.

Conclusions:

  • Reduced RT in late gestation is a significant indicator preceding calving.
  • RT monitoring shows potential as a tool for predicting calving timing in dairy cows.
  • Further research is needed to validate RT as a predictive calving indicator.
