Why Protein Isn’t the Problem—Energy Is

March 13, 2026 /
Why Protein Isn’t the Problem—Energy IsIf you hang around a feed store or sale barn in late winter and early spring, you’ll hear the same advice repeated like clockwork: “They probably need more protein.” It’s almost automatic in cattle nutrition conversations. Cows looking a little thin? Add protein. Calves not gaining as you expected? Add protein. Grass just starting to green up? Add protein.
But the reality for many cow-calf operations is that protein usually isn’t the main issue. Most of the time, it’s actually energy that’s lacking.
And when energy intake is short, nothing else works the way it should. Body condition slips. Reproductive performance stalls. Milk production levels off. Even immune function can take a hit. You can add more crude protein, but if cows don’t have enough digestible energy to fuel rumen microbes and maintain metabolic demands, that extra protein won’t solve the root issue.
This doesn’t mean protein isn’t important for beef cattle. Protein plays a key role in rumen function, growth, and herd performance. However, in late winter and early spring, when forage quality drops, hay is harder to digest, and early grass is wet but low in dry matter, energy is often the real limiting factor.
Before spending more on protein tubs or high-protein supplements, pause and ask the key question: Are my cows short on energy rather than protein? This is crucial for improving performance.
Let’s look at why energy is so important for cattle in late winter and early spring, why it’s often the nutrient that runs short, and how you can tell if your herd’s problem is really a lack of energy rather than protein.

Don’t Quit Feeding Hay Too Soon in March

February 25, 2026 /
Don’t Quit Feeding Hay Too Soon in MarchWhen March arrives, most cattle producers are eager to stop feeding hay.
Winter feels endless. A few warm days appear, pastures show a faint green, and the cows aren’t crowding the gate as much as in January. After months of rolling out bales, it’s easy to wonder, “Why are we still feeding hay?”
That’s when the thought comes up: Why not stop feeding hay and let the cows graze?
But giving in to this idea often leads to a common March mistake: stopping hay feeding too soon.
The issue isn’t stopping hay feeding, but stopping it too quickly.
March is a time of transition, not the finish line. Early grass looks promising, but it usually doesn’t give cows enough to eat. If you stop hay suddenly, cows may graze more but actually eat less, which can cause intake drops, loss of body condition, and performance problems that show up weeks later.
That’s why this isn’t the time to stop hay feeding all at once. Instead, it’s time to reduce it gradually and with a plan.
In the next sections, we’ll cover why removing hay too quickly hurts intake, what happens in the rumen during this change, and how to cut back on hay in a simple, low-stress way. The main point is that a gradual step-down keeps cows eating, protects rumen health, and helps your herd have a productive spring. The most important thing to remember is to keep nutrition steady in March.

Why Roughage Is the Foundation of Cattle Nutrition

February 17, 2026 /
Why Roughage Is the Foundation of Cattle NutritionWhen feeding cattle, most people focus on protein, energy, and minerals. But roughage plays a key role in a healthy diet. Without enough roughage, a cow’s digestive system won’t work as it should. Roughages provide the fiber that keeps the rumen active, helping cattle break down feed, absorb nutrients, and stay productive. In short, roughage forms the base of the whole diet.
The effectiveness of the rumen depends on its microbial population and adequate fiber. Acting like a fermentation vat, it is full of millions of microbes that turn tough plant fibers into energy for cattle. These microbes can’t do their job with concentrates alone—they need fiber. Without enough roughage, the rumen slows down, digestion gets less efficient, and cattle don’t perform as well. Over time, a lack of fiber can cause cattle to eat less, lose weight, produce less milk, and face more digestive problems. Providing enough good-quality roughage keeps the rumen healthy and everything running smoothly.
The quality of roughages varies widely and is a key factor in cattle nutrition. Forage quality depends on rainfall, plant maturity, harvest timing, and management. Young, well-managed forage is easier for cattle to digest, while older or weather-damaged roughage often lacks nutrients. Poor-quality roughage may fill cattle up, but it doesn’t support the best performance. Focusing on roughage quality, not just quantity, helps fill nutrition gaps, protect rumen health, and keep cattle productive year-round.
