Body Condition Scoring is Important for Dairy Cattle, Too
Body condition scoring can be used to subjectively assess the amount of external fat that an animal carries. In short, it is a tool that can be used on-farm to help determine if there are nutritional or management issues that may need to be addressed. Ensuring proper body condition throughout lactation will help cows remain productive and healthy members of the herd.

Considerations for Selective Dry Cow Therapy

Ketosis in the dairy cow: Friend or Foe?
We commonly see ketosis as an energy disorder of the modern dairy cow, a telltale that things are not going well, and one that hints at poor fertility, reduced lactation performance, and an increased risk for the development of early lactation diseases. In practice, ketosis is diagnosed by the measurement of beta-hydroxy butyrate (BHB), one of two major ketones, that becomes elevated in blood, urine, and milk of fresh cows. In this way, ketosis is used as a cow-side test for identifying sick cows, and as means to direct our efforts to “problem cows” (for example with propylene glycol administration) before it is too late. Despite our efforts for ketosis prevention and treatment over the last 5-7 decades, our understanding of ketosis as a disease, as well as our ability to reverse it and to prevent the arrival of other associated disorders (for example displaced abomasum, infection, fatty liver, milk fever), remain limited.Title: Ketosis in the dairy cow: Friend or Foe?; Authors: Naghme Bagheri, Ph.D., and J.
