Busting the Myths around Transition Cow Management

Because of the extensive evidence for potential negative outcomes associated with elevated NEFA and BHBA, several large epidemiological studies have been conducted to identify a critical blood concentration in which negative effects may be expressed in transition cows. Since BHBA are far more commonly measured than NEFA, it has been the focus of many of these studies. The studies are fairly consistent in suggesting that 1.2-1.4 mmol BHBA/L is the point in which milk production is likely to be reduced. Consequently, it is commonly recommended that if 10-15% or greater of the cows tested are at 1.2 (or 1.4) mmol BHBA/L or above, an alarm level has been reached and causes should be identified.
