Research in the use of supplemental methionine in dairy rations continues to expand as methionine has come to be recognized as an essential nutrient for dairy cows. One focus in this expansion is cow health.
Particularly critical to dairy cow health are the weeks immediately after parturition. During the transition phase from dry cow to lactating cow, the incidence of metabolic diseases peaks and can be a primary deduction from the economics of milk production. The most common clinical conditions include milk fever, dystocia, retained placenta/metritis, ketosis, left displacement of the abomasum, clinical mastitis, and lameness.
