Relationship between level of milk production and estrous behavior of lactating dairy cows

Relationship between level of milk production and estrous behavior of lactating dairy cows

The objective of this study was to determine if there is an association between level of milk production and duration of estrus as determined by standing activity recorded by a radiotelemetry system. Holstein cows ( n=267; 50 DIM) were fitted with a transmitter that allowed continuous recording of s...

Zusammenfassung:The objective of this study was to determine if there is an association between level of milk production and duration of estrus as determined by standing activity recorded by a radiotelemetry system. Holstein cows ( n=267; 50 DIM) were fitted with a transmitter that allowed continuous recording of standing activity. Cows were housed in a free-stall barn and milked twice daily. Ovulation was confirmed for all estruses ( n=380). Average milk production for the 10 days before the day of estrus was used to classify cows as lower (
