Set Calves Up for Success with Low-Stress Weaning

Weaning is no doubt one of the toughest times in a calf’s life. How it’s managed can shape performance – positively or negatively – for months afterward.  

Other stressors can compound the issue. This includes moving to new pens, vaccinations, navigating new water and feed sources and sometimes transportation. Collectively, this suppresses immune function when calves need it the most, when they come of age to be commingled with other livestock and enter new environments. 

The payoff for getting weaning right is a big one. It contributes directly to better weight gain, fewer treatment costs, stronger immunity and an overall smoother transition into the next production phase. Producers who plan ahead stand to see the difference in the scale house. 

Start with preparation

No matter what weaning method you prefer, one of the keys to implementing a low-stress process is starting gradually. Simple acts leading up to the big day could include getting calves accustomed to human presence and moving them into corrals and holding pens with their mothers just prior to weaning.  

Other good practices include staggering management practices so calves are not hit with every stressful event too closely. Mark your calendar to ensure you have adequate space between weaning, vaccinations, branding, tagging, castration and similar events can promote immune response.  

Building a low-stress environment

Before calves ever move through a chute, it is a good idea to walk the facility. Check fences, gates and latches, repair sharp edges and broken boards, and make sure alleys and pens offer solid footing. A properly maintained handling system, working with small groups, patience, and respecting flight zones all cut down on balking and injury. 

Fenceline and two-step weaning are two low-stress alternatives to abrupt separation that have gained traction in extension research.  

According to South Dakota State University (SDSU), extension-fenceline weaned calves in Utah studies vocalized less, ate more and gained more weight than calves abruptly separated from their dams. That advantage held for 10 weeks post-weaning. Two-step weaning, which uses anti-suckling nose flaps before physical separation, showed similar benefits. The calves fitted with nose tags gained nearly 1.5 pounds more per day than untagged calves during the pre-separation period in SDSU trials. 

Mabry Bruhn, writing for the University of Illinois extension’s Cattle Connection blog, outlined the same three broad approaches categorized as two-step, fenceline, and hard weaning. She notes that hard weaning “consolidates what could be a few stressful workings into just one big event” but trades that convenience for higher stress.  

Bruhn also pointed to appeasing pheromone as a newer tool in the handling toolbox, since applying a synthetic maternal scent near a calf’s nose can help lower cortisol at working time. 

Research on one such product, FerAppease, backs that up in the feedyard setting. In a commercial feedlot trial summarized in the Nebraska Beef Cattle Report, researchers Loseke, Erickson, and Sperber found that steers administered FerAppease “tended to have improved feed conversion on a carcass-adjusted basis” when applied at arrival and reimplant, though intake, gain, and carcass traits were not significantly affected. 

Feed and water management

Water intake is easy to overlook and hard to recover from once it slips. Clean tanks before weaning and verify flow and capacity. You want it to be as easy as possible for calves to access, so make sure the tank is an appropriate type and has no mud build up that makes it difficult for calves to drink. Water intake should be watched closely during the first several days after separation. 

Introducing feed bunks and starter ingredients before weaning day means calves are not learning two new things – both where the feed is and how to eat it – all at once. After separation, a high- quality forage base and balanced starter ration, fed consistently and without abrupt changes, keeps intake steady. Bunks should stay clean and free of overcrowding, with daily monitoring so amounts can be adjusted before waste or refusal becomes a pattern. 

Vaccination and other veterinary work

Administering core vaccines ahead of weaning rather than during or after gives calves time to build immunity before the stress of separation hits. Julia Herman, DVM, writing for the Beef Quality Assurance program, described preconditioning under the U.S. Department of Agriculture’s National Animal Health Monitoring System framework as practices that help a calf adjust.  

She notes that weaning at least 45 days before sale, alongside castration, dehorning, and a full vaccination protocol, should all be part of a preconditioning program. Herman says that working with a herd veterinarian to build the protocol rather than defaulting to a generic schedule, is a wise choice since operation specific risk factors all shape the right timing. 

Remember that low-stress weaning isn’t one single technique or method. Truly low-stress practices consider the before, after and during for the animals involved. Everything works towards the end goal of keeping things familiar and calm for the calves so that they can recover quickly. Producers who spread those decisions out, rather than loading them all onto separation day, consistently see it pay off in fewer treated calves and a stronger start into the next phase of production.
