When should dairy cows get their first dose?

Best practice is to base dose timing on combination of changes in yield, condition and levels of coughing when exercising. Often, dosing before these symptoms will cause an increase in yield. This is because there is an energy-cost of maintaining natural immunity and treatment reduces this cost on the animals metabolism, leaving more for milk production. However, dosing too frequently will accelerate the onset of resistance to wormers.
