Effect of starch and forage NDF concentrations on intake, milk yield and composition of dairy cows receiving rations containing OneTrak®
OBJECTIVE
The objective of this study was to evaluate the effects of feeding OneTrack® on feed intake, milk yield, and glucose metabolism of lactation Holstein dairy cows receiving varying levels of starch and forage NDF.

Effects of NexPro® on feed intake, feed efficiency, feeding behavior, and apparent nutrient digestibility of early lactation dairy cows
OBJECTIVE
The objective of this study was to evaluate the effects of replacing soybean protein with NP on DMI, feed efficiency, feed behavior, and apparent nutrient digestibility of early lactation Holstein dairy cows.

Association of β-hydroxybutyrate with time eating and ruminating as determined by an ear-based sensor in transition cows
OBJECTIVE
Investigate the association of β-hydroxybutyrate (BHB) with feeding behaviors reported by an ear tag-based sensor and determine if differences exist between parities.
