Across West Texas and the Southern Plains, a pasture may still look pretty decent from the road. There may be green color left, grass standing, and cattle scattered about, as if everything is working fine. But just because there is forage in front of your cows does not mean it still has the same nutritional value it had back in April or early May.
That is where summer forage maturity can sneak up on a cattle operation. Spring grass is usually tender, leafy, higher in protein, and easier for cattle to digest. Once the heat settles in, those same plants start getting stemmier and putting more energy into seedheads. The pasture may still have volume, but forage quality, protein levels, and digestibility can begin to slip quickly. Cattle may be eating, but they may not be getting as much usable nutrition from every bite.
This matters if you are running pairs, trying to get cows bred back, raising replacement heifers, or keeping stocker cattle gaining weight through summer. The first signs are often subtle. You might see cows losing some body condition, calves not gaining as fast, manure getting drier, or cattle grazing longer without much improvement.
So in June, do not just ask, “Do I have grass?” Instead, ask, “Is this grass still meeting my cattle’s needs?”
This is why adjusting cattle supplements is a smart management move, not just another cost. A solid summer supplement plan fills the gaps left by mature forage and helps keep cattle performance steady before problems get costly.
