A lot goes into achieving a successful calving rate in your herd-including, of course, what goes into your cows. University of Minnesota Extension dairy nutritionist Noah Litherland says one of the biggest challenges in dairying is getting cows back into positive energy balance after calving; he says strong feeding strategies for both dry and fresh cows are part of the solution, and it's important to ensure there's adequate macro- and micro-minerals in the diet.
