August pasture can be deceiving at first glance.You might see grass still standing and looking green from the road. Cows may be spread out grazing as if all is well. But that does not always mean the grass has the nutrition your cows need.
By late summer, forage quality often drops. As grass matures and the heat continues, dry weather can lower both protein and energy. So, even if a cow is surrounded by grass, she might still not get enough nutrition.
If you notice cows losing body condition, calves looking a bit hollow, or cattle grazing longer than usual, pay attention. These signs may mean your pasture is not providing what it did earlier in the season.
This is why judging pasture from your truck can be misleading. Having a lot of grass does not always mean it is good quality.
In this post, we will cover what happens to forage in late summer, why cows might lose condition even when pastures look full, and how to decide if supplements are needed. The aim is not to feed just because it is August, but to understand what your grass is really providing before your cows suffer.
When spring breeding season ends, most people are ready to pull the bulls, close the gate, and take a break. That makes sense. Breeding season is hard work, especially in tough country, hot weather, big pastures, and with cows that are not easy to find. But the work is not finished when the bulls leave the cows. For many herds in West Texas and the Southern Plains, this is actually when next year’s breeding season begins. If a bull comes off cows thin, sore, footsore, heat-stressed, or dealing with parasites, he needs care now—not next spring when it is too late.
If you’re planning to wean calves this fall, August is when you need to get started.
In August, pastures can be deceiving.
If you walk through a West Texas pasture in August, the grass will usually show you what is really happening, even if it is not what you want to see. Maybe the old bluestem is thin near the water lot. Maybe broomweed has popped up in a pasture that looked good back in the spring. Maybe ragweed is filling in bare spots, or silverleaf nightshade keeps returning, no matter how many times you thought you had it under control. Most ranchers see these plants and immediately ask, “What do I need to spray?” That is a reasonable question, but it should not be the first one. A better question is, “Why is this weed showing up here?”
If you could put more weight on your calves before weaning without having to buy extra feed every week, wouldn’t you want to try it?
August really shows you how your replacement heifers are doing.
Late in the summer, a pasture might look better than it really is.
By July, mineral feeders can reveal a lot about your whole operation if you know what to look for.
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.
