DSD 6.1 | Management to create the invisible cow
If you pause and think about a list of cows - chances are the list that pops into mind is a group of troublemakers that didn’t breed back or need another round of treatment or are on this week’s cull list. What if you could create a herd of unmemorable cows - ones who just do their job; make milk, breed back, no mastitis - the "Invisible Cow". Dr. Krogstad’s research program’s goal is to create more invisible cows; ones you only see at calving, breeding and dry off. This month he shares with us a dataset analyzed for associations of hyperketonemia (HYK) with body condition, milk production, pregnancy loss, mastitis and ultimately culling.
It turns out that the timing of lipolysis determines if it is healthy or harmful and ultimately has a big impact on her success through transition. It all boils down to are the free fatty acids being mobilized to fuel early lactation being completely oxidized or partially oxidized?
