Montana veterinarian encourages a fresh look at deworming protocols Is it time to take review your herd’s deworming program to identify areas of improvement? With more than a decade of experience working with cow-calf producers, she says it never hurts to take a fresh look at your herd’s deworming program to identify potential areas of improvement. Dr. Neal manages her own herd of registered and commercial Angus alongside her husband and father-in-law. Over the last few years, Dr. Neal has worked to optimize the timing of her deworming program — and now she tries to deworm calves as early as possible each season for maximum benefit. “Preconditioning calves is another thing that I’ve been highly recommending to producers in the last few years,” Dr. Neal says.
