July is when you find out if your cow nutrition plan is working or falling short. Grass might look fine from the truck, but that does not always mean it has enough protein, energy, or digestibility for a lactating cow during breeding season. This is important because after calving, a cow has a lot on her plate. She needs to raise her calf, recover from calving, regain body condition, and get ready to breed again on time.Having a calf every year is not just a bonus—it is what keeps a cow valuable in the herd. With rising costs for feed, fuel, labor, and pasture, every cow that does not breed back costs you money. If a cow falls behind on nutrition during this busy time, you might not notice the problem until preg-check, when it is too late to do anything about it.
Here is the bottom line: cows cannot breed back if they are running on empty. A good nutrition plan starts with knowing what your forage really offers. Is the grass good enough to support milk and reproduction? Is there enough for cows to meet their needs? Are you feeding mature cows, young cows still growing, or thin cows trying to catch up?
Meeting these needs is more than just tossing out feed and hoping it works. You need to match forage quality, quantity, minerals, and supplements to each cow’s stage of production. When cows get the right nutrition at the right time, they are more likely to stay in good shape, breed back, and raise calves that make you money.
At first glance, late summer pastures can look like everything’s fine—plenty of tall, green grass waving in the breeze. But here’s the thing:
