چکیده
The Vital 90TM Days begins approximately 60 days prior to calving and continues through the first 30 days of lactation. During this time, dairy cows experience a series of biological and physiological transitions that are usually accompanied by large changes in feed intake, dramatic shifts in hormonal profiles, and major fluxes in hepatic demands and function. The resulting negative energy and negative protein balance as well as immune suppression often lead to a multitude of metabolic and infectious problems including, but not limited to, retained fetal membranes, ketosis, metritis, displaced abomasum and mastitis among others.
