As pastures continue to “green up,” spring progresses, and cattle transition from hay to pasture, beef herds throughout the state can benefit from supplemental Co-op minerals to optimize performance and improve herd health. In fact, these minerals are necessary in most cases to provide key elements that are required to keep cattle performing at their best, say ProTrition livestock experts.
“Co-op minerals are formulated to help our cattle get the most out of our forages,” explains ProTrition Livestock Sales Specialist Gary Williams. “They’re designed with the typical conditions that Southeast beef producers deal with. Our cattle won’t perform best on grass alone. These minerals have the right ingredients in the correct amounts to enhance cattle growth, reproduction, and general health and condition.”
Zach Fuller, a commercial beef operator in Wartrace, has been using Co-op minerals exclusively since 2022 and says he can see the positive results that minerals play in both the herd’s conception rate and their uniform calving window.
Zach started helping his father-in-law, Rocky DaCosta, manage his Angus herd in 2015, and then bought his own cows the following year. Their partnership consists of a cow-calf venture, where calves are born, weaned, backgrounded, and then uniform groups are sold through a video auction.
They utilize three different Co-op mineral blends purchased from Lincoln Bedford Moore Farmers Cooperative in Shelbyville — Co-op Foundation Hi-Mag Cattle Mineral (#675) fed winter through about April 15 — followed by Co-op Foundation Cattle Mineral with altosid (#96306), an insect-growth regulator (IGR) for fly control. The Fullers then use Co-op Supreme Cattle Mineral (#678) during breeding season.
“Since I have been using Co-op minerals, roughly 83% of my cows have their calves within a 30-day window,” Zach says. “That’s ideal. Size-wise, we want the most uniform calf crop we can get.”
In addition to improved calving rates, Zach has noticed more predictable consumption since switching to Co-op mineral.
“Co-op mineral has a coating which keeps it from hardening or clotting up as bad when it gets wet or damp,” says Zach. “Other mineral that we have fed in the past hardened up when it got wet because it didn’t have that coating, and the cattle quit eating it. When this mineral gets wet, our cattle still consume it.”
Zach and Rocky, a former director of Lincoln Bedford Moore Farmers Cooperative, have a combined total of around 550 cattle spread out over about 2,200 acres of owned and rented land. They save roughly 60 heifers a year to replace older cows that leave or cows that are open. They harvest and feed their own hay and provide ProLix — a protein-enriched, molasses-based liquid supplement — to younger females that need additional nutrition.

Co-op Hi-Mag Cattle Mineral (#675) is fed to the herd each winter through early spring during breeding season, Zach says.

Zach says that since using Co-op minerals, 83% of his cows have their calves within a 30-day window.

Eight-year-old Lane enjoys helping his father and grandfather on the farm. He checks for calves, helps cut and bale hay, feeds, loads, and takes trips to the sale barn every chance he gets.

“We are not high-cost producers,” Zach says. “We try to minimize our expenses. And Co-op minerals help us accomplish our goal.”
In Lexington, First Farmers Cooperative customer James Beaty and his son, Jesse, use Co-op Supreme Repro Mineral (#96678) and Co-op Balancer Cattle Mineral – Mon (#649) to support the AI (artificial insemination) breeding program on their registered Angus operation, Beaty’s Double J Angus Farms. On the 450-acre property, the Beaty’s raise around 100 head of cattle and 15-20 bulls, all registered, and generally retain their heifers while selling the bulls to regional registered and commercial operations. They also produce ryegrass for haylage.
James says that their mineral usage is a direct reflection of the farm’s breeding program.
“Every year, we AI everything once in a very tight timeframe,” says James, who also works as a fisheries technician for the Tennessee Wildlife Resources Agency. “We try to stay within a 35- to 40-day calving period, which is really tight. We don’t always maintain that, but that’s our goal. If you have all those calves at the same time, it keeps the bulls consistent and the heifers breeding at pretty much the same time. This is important because, when you put them back into the herd, you can still maintain that calving window.”
Jesse adds that the tight calving window also makes day-to-day farm chores more efficient.
“It allows you to do your farm chores at the same time,” says Jesse, who also works for the City of Lexington Street Department. “If you get [the calving] done within 40 days, when you’re done calving, you’re done. And even when we’re breeding, it’s all at one time. We always shoot for breeding on December 12.”
James explains that if the AI doesn’t “stick” within the first cycle, they can try again 21 days later.
“This gives us two cycles within a 42-day period to get them bred,” he says. “Any cows that are not bred within that window for whatever reason are gone; we just don’t keep them.”
He reports that out of 70-80 cows, they will probably have only six or seven calves that are not conceived via AI, an impressive number that James largely attributes to his mineral program.


Freddie Edward’s cow-calf herd is thriving with the addition of supplemental nutrition from Co-op minerals to their diet. Freddie says the cattle are in good condition and he’s pleased with the calving rate for his operation at Springfield.
“We might feed a little hi-mag mineral in the spring depending on the conditions, but for the most part, those cows are on the Supreme Repro mineral year-round,” he says. “The high phosphorus content is important because the soils in this part of the country are a little deficient in phosphorus, so we have to make up for that. The mineral keeps them in excellent body condition.”
In Springfield, Freddie Edwards has experienced similar benefits in his herd. He has a cow-calf operation of about 100 mama cows along with a row-crop operation. His farm consists of 600 acres, of which about 200 are pasture and hay and the majority of the rest is for row-crops. He typically buys older cows rather than heifers in the hopes of avoiding calving difficulties with the younger animals. He says his strategy is to manage the herd to provide two calving groups each year.
“I have a spring group and a fall group,” he says. “ I will keep the calves born in the fall until next June. Those born in the spring are usually sold in September or October. I usually sell them at 600 to 700 pounds. Sometimes I like to keep them a little longer in the fall, but the grass is usually beginning to get weak around that time, so it depends on the season.”
He relies on a bull for natural breeding and strives to keep the calving interval as tight as possible. This past fall, his 60 cows in the group had 40 calves in 32 days. But he says he doesn’t stress over the calving interval.
“A late calf is better than no calf,” he says.
His mineral program is key to helping meet his goals, as he manages his operation with little extra labor, and strives to keep his production efficient. The herd receives Co-op Supreme Hi-Mag Mineral (#638) from fall through April, which, he says, has led to good results. From April to October, he transitions to Co-op Foundation Cattle Mineral-Altosid (#962306). He also uses Co-op Hi-Mag Mineral during the critical grass tetany season and relies on Co-op 32% Hi-Pro Cattle Supplement Tubs (#900581) for convenience. The 200-pound tubs offer 32% crude protein to support muscle development and overall health.
“I don’t have full-time help, so I look to these [tubs] as a way to help me manage while reducing labor and providing the cattle with the protein they need,” says Freddie. “I think the cattle look good. Their reproduction has been excellent and their body condition looks good.”

On the 450-acre Beaty’s Double J Angus Farms in Lexington, father and son James and Jesse Beaty rely on Co-op Supreme Repro Mineral and Co-op Balancer Cattle Mineral to support their carefully managed AI breeding program. The Beatys stay within a strict, 35- to 40-day calving period.

From left, Jesse, James, and Jason Hearn, livestock sales manager for First Farmers Cooperative, discuss the Beatys' feed and mineral program. Hearn, who also purchases registered bulls from the Beatys for his own beef operation, says consistent offering of the Repro mineral is critical for maintaining the farm's high conception rates.
