In March, most cattle producers are thinking about spring grass, dealing with muddy gates, and cutting back on winter feeding. Mineral programs often get overlooked. But this is when late-winter mineral deficiencies tend to show up in beef cattle.The signs are usually subtle, not dramatic. You won’t find a disaster in the pasture. Instead, you might notice a cow not cycling on time, a calf lacking its usual shine, or a group that just seems a bit off. Nothing clearly points to a mineral problem, but something isn’t right.
And most of the time, the issue didn’t begin in March.
The problem often begins in December or January, when cows start depending more on stored forage. As winter goes on, they use up their internal reserves, especially for nutrients like copper, phosphorus, and vitamin A. By March, these reserves are low, and performance can drop.
Late-winter mineral gaps show up now because the cows’ reserves are nearly gone. Reproduction, immune function, and calf growth are usually affected first. This is why managing minerals in March is more important than many producers think.
Here’s what you should know as we move into spring: (1) why late-winter mineral issues happen, (2) the early warning signs to watch for, and (3) immediate steps you can take to protect herd intake, reproduction, and performance.
When 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.
Creep feeding allows calves to access feed that mature cows cannot. This practice can promote superior calf growth and raise weaning weights, meaning the calf’s weight when separated from its mother. Elevated weaning weights typically result in higher sale prices at year’s end. Providing calves with a digestible supplement supports growth even if forage quality or milk yield declines. Still, creep feeding is not a universal fix. Like any cow-calf management decision, it is most effective when applied strategically for clear objectives.
If you asked most cattle producers when cows tend to lose body condition, January would probably be the first answer that comes to mind.
February is one of those sneaky months in the cattle business that can catch even experienced producers off guard.
When it comes to cattle supplements, most producers have a classic love/hate relationship with them. You know they can boost performance, improve body condition, and keep cows productive through tough forage seasons… but you also feel that sting when you look at the price tag. It’s the reason many ranchers wait until the last minute—or until cows start dropping condition—to bring supplements into the mix.
If there’s one time of year you absolutely cannot afford to fall behind, it’s the 60–90 days leading up to calving because winter management directly influences calving success and herd health.
When it comes to managing cattle, salt probably isn’t the first thing that comes to mind. We think about hay quality, protein supplements, or mineral tubs long before a plain white block of salt. But the truth is, salt is one of the most essential—and often overlooked—tools in a rancher’s nutrition program. Just like people, cattle need salt every single day to support key body functions like digestion, muscle movement, and nerve activity. When salt is lacking, everything from feed efficiency to growth and reproduction can start to suffer.
If you’ve ever been out checking cows in late fall and thought, “Maybe I should start feeding them a little,” you’re not alone. Every year, as the grass starts to fade and mornings get crisp, ranchers across the country ask themselves that same question.
When it comes to cattle nutrition, the ‘big three’ —
