Weaning calves at half the typical age calls for re-thinking your calendar, but it doesn’t obligate a management overhaul. With a few key tweaks, ranchers already weaning at home can reap the rewards of calves that gain faster, convert cheaper, perform better and reduce cow costs.
“We started weaning calves early because of drought,” said ruminant nutritionist Jeff Heldt. “Now we do it because it makes sense from a cow feed-cost and grass-availability standpoint.”
Heldt, a field consultant for Land O’Lakes Purina Feed, works with cattlemen in the western portions of Nebraska and South Dakota who have moved their weaning date toward a 90-day target. The result? An average savings of $40 per cow in feed costs and 25 percent increase in forage availability.
“You can’t feed a more efficient beef animal than one that is 100 to 200 days of age,” Heldt said. “If you’re feeding calves clear out to finish, you can really take advantage of this in the areas of feed efficiency and carcass quality. In an early-weaning program, these two things are going to be money makers.”  
It works; that’s proven. But don’t jump in without careful evaluation on your own terms. Marketing, facilities and management plans must be in order to avoid weaning sooner than you or the calves are ready.

Market planning
Like some of Heldt’s customers, Brush, Colo., rancher Justin Curtis weaned his first set of 90-day-old calves when faced with sparse forage.
“We make those decisions year-to-year based on what we have in the pasture. In those really dry years on native grass, pulling the calf off sure helped the cow keep weight on and helped cut back on the feed bill,” he said.
Calves went directly to the Certified Angus Beef LLC (CAB)-licensed Chappell (Neb.) Feedlot, where owner-manager Tom Williams says resource evaluation is crucial.
“Out in that high desert country, they don’t always have the resources available to support a cow and a nursing calf. So getting the calf off and into the yard right away works – but it wouldn’t fit everyone,” the Nebraska manager said.
Heldt recommended starting with a marketing goal. Unless a feedlot is prepared to take on a 350-pound (lb.) calf, he says the early-weaning model best suits ranchers who already wean and background calves. For them, there are two options:  Sell a heavier calf at normal marketing time, or target a normal finished weight but hit the market before prices are saturated with cattle from traditional programs.
Finishing the long-fed animal takes experience, however.    
“These little calves are so efficient and can gain so rapidly that a person can overshoot a finish quicker than expected,” Heldt said. “So the end marketing date or weight needs to be thought of first, then back-calculate the performance.”
Running accurate projections can be difficult without background data, too, but Heldt recommended plugging in a 4:1 to 5:1 conversion rate of feed to gain.
“You’re going to spend a little more money feeding calves that you normally don’t spend,” he said. “But you’re gaining an advantage on feed efficiency and weight gain. At the same time, your cow is gaining weight and she’s eating 25 percent less feed – that has a significant dollar value as well.”

Considering Facilities
Whether you’re considering dry-lot weaning or separating pairs along a pasture division, Williams said facilities need to revolve around one thing: “A really good fence.”
Heldt agreed. “It sounds simple, but you just have to walk through every place those cattle are going to be and think, ‘Is this appropriate for an animal half the size of what I’m normally dealing with?’ Look at the feed bunks, the water – can they reach it? Look at the fence – can they crawl under or through it?”
A fence-line is certainly important, but it doesn’t have to be a fence-line feedbunk.
“Fence-line weaning these young calves is a pretty ideal situation – there’s no reason you can’t accomplish the same gain out on pasture with the right supplements,” Heldt said. “Leave the calf on the pasture he came from with a supplement or self-feeder, put mom elsewhere, and let those calves stay home and perform – you really don’t need to bring them into a dry lot.”
Williams said the bottom line is simple. “Weaning at home takes a little bit of skill and knowledge, no matter what age the calf is. We’ve got to have open lines of communication between the cattlemen, their vet and us here at the feedlot to make sure we’re taking care of that animal and maximizing its profit potential from start to finish.”
