BS in Dairy Science Dairy Science Department The objective of
this study is to determine if there is a direct relationship
between rumination and energy corrected milk produced, using a
technologic rumination tracking system. This technology is
better known as AI24™ and is produced by Micro Dairy Logic:
Advanced Dairy Solutions and SCR™, but marketed through Semex.
The collar system is able to track rumination, aid in diagnosing
illness/injury, predict parturition, and detect estrus in cows.
The sophisticated electronic tag monitors a cow’s rumination
time, chewing rhythm and time between feed boluses to determine
how many minutes per day the cow is ruminating. Each collar is
equipped with a microphone, which is used to monitor the
rumination patterns. A protocol was implemented so that all
fresh cows received a collar before entering the milking string
to establish a baseline. This allows the baseline to be
established by 21 days in milk. The collars are read through a
system of infrared sensors located in t
