Area of Science:

  • Animal Science
  • Agricultural Engineering
  • Dairy Science

Background:

  • Accurate estimation of feed intake is crucial for dairy cow management and research.
  • Traditional methods for monitoring feed intake can be labor-intensive and inaccurate.
  • Developing reliable, non-invasive devices for tracking animal feeding behavior is essential.

Purpose of the Study:

  • To develop and validate a simple, compact bite counter for recording dairy cow jaw movements.
  • To assess the accuracy of the bite counter in estimating feed intake under different pasture conditions.
  • To evaluate the practicality and usability of the device for farmers and researchers.

Main Methods:

  • A pendulum-based bite counter attached to a collar recorded jaw movements.
  • Data on bite counts were collected at 10-min intervals and stored for up to 3 months.
  • The bite counter's accuracy was validated against direct observation and pasture disappearance measurements in nonlactating and lactating Holstein cows.

Main Results:

  • The bite counter demonstrated a high linear correlation (R(2) = 0.9) with direct jaw movement observations, unaffected by rumination or walking.
  • Feed intake estimation using bite counts and pasture disappearance yielded regression lines with R(2) values greater than 0.7.
  • The collar-mounted system proved more practical than halter-attached devices, with a battery life exceeding 1 year.

Conclusions:

  • The developed bite counter is a simple, accurate, and practical tool for estimating dairy cow feed intake.
  • The device effectively records grazing jaw movements and can be used to monitor pasture consumption.
  • This technology offers a valuable resource for improving dairy farm management and research accuracy.
