In May, green grass can be deceiving. From the truck, everything might look fine and the cows seem happy, so it’s easy to think the pasture has it covered. But this is often when mineral needs catch you off guard, especially as spring grass matures, summer heat arrives, and breeding season approaches.Many people focus most on cattle mineral supplements in spring and fall, which makes sense. Spring means calving, milk production, and pressure to breed back. Fall brings weaning, changing forage, and getting ready for winter. But mineral nutrition is just as important in summer. In fact, letting mineral intake drop in summer can be costly.
For many cow-calf operations, summer is also breeding season. If cows don’t get enough key minerals, they might not cycle properly, breed back on time, or perform as needed for a strong calf crop. These problems might not show up right away, but later you could see open cows, late calves, lighter weaning weights, and more frustration.
The challenge is that pasture quality changes at the same time. Lush spring grass becomes stemmy, matures, and loses nutritional value. So while your cows need good mineral support for reproduction, immunity, and health, the grass may not provide as much as it did just weeks ago.
That’s why it’s important to pay attention to your summer mineral program. With a few simple checks, you can spot gaps early and keep your herd healthy before small issues become expensive problems.
