The invention comprises an improved method for administering calcium dosages to periparturient dairy cows, resulting in significant decreases in the incidence of milk fever and retained placenta. The single dosage comprises 18 to 36 grams of readily absorbable calcium, preferably finely powdered calcium carbonate in an amount which provides about 30 grams of available calcium. The dosage, preferably in the form of one or more compacted pellets, is administered orally within a period of 0 to 8 hours (preferably 0-2 hours) after parturition. The oral dosage is forcefully administered, as opposed to being offered to the cow in the form of a feed or drinking water supplement.

Method for reducing incidence of periparturient disorders in cows

Dairy cattle rations are formulated to optimize milk production by balancing the proportion of soluble and insoluble protein in the total dietary protein. The ration may include both forage and concentrate portions, in which case the forage portion may consist of grazing and/or available stored forage with the composition of the concentrate being adjusted as required to provide the required balance of soluble and insoluble protein. The total protein intake is established according to standard recommended levels based on a particular cow or herd's production level, and other factors. The proportion of the total protein which is soluble in the cow's rumen is limited to not more than 25%, but some soluble protein, preferably in a range of about 10% to 20% is provided since it is this protein which is used by the microorganisms in the rumen which are, in turn, used by the cow as protein.
