Prevent Milk Fever

Prevent Milk Fever

Fresh cows that have been on a diet of forages high in calcium and potassium often are in for a rude awakening at freshening: hypocalcemia, also referred to as parturient paresis or “milk fever.” According to Cornell University’s College of Veterinary Medicine, clinical milk fever costs producers about $334 per case.

Forages high in calcium and potassium fed in the dry period can set cows back at freshening, because they make calcium too readily available in the bloodstream. Ration manipulations can help disrupt this process. Often this is achieved by switching to lower-nutrient forage sources in the dry period. Employing a dietary cation-anion difference (DCAD) strategy in the dry period also has been shown to reduce milk fever incidence. This precise method of dry cow ration control can be achieved by feeding an anionic mineral supplement to close-up dry cows.  Be sure to contact your Nobis Agri Science nutritionist to discuss specific rations for your dry cows and fresh cows.
