Preplan preconditioning tasks

READY TO GO: The goal of your farm’s preconditioning program is to build a health and nutrition plan that meets the buyer’s expectations and includes tasks your farm can achieve.
Beef Column: Prepare calves for a successful weaning and life afterward.

Preconditioning beef calves prepares them for a successful weaning and life after they leave home. Calves not preconditioned are frequently discounted at market because they are more likely to suffer health problems and perform less efficiently, and ultimately, have lower-valued carcasses. The goal of your farm’s preconditioning program is to build a health and nutrition plan that meets the buyer’s expectations and includes tasks your farm can achieve.

Buyer preferences and expectations include calves that are castrated (knife cut preferred), dehorned, eating well at a bunk and drinking water on their own. Health program status is also important, so be sure to share your calves’ vaccination and deworming status, including what products were administered. To help with that, we have designed a Preconditioning Record Form that is available at

Some farms don’t precondition calves because they do not have facilities to handle cattle or feed calves, nor time to accomplish the tasks involved. These are poor excuses! Learn about cattle handling and invest in facilities that allow you to handle cattle in a safe and timely manner. Videos and print resources are available from National Beef Quality Assurance.

Preconditioning schedule

I worked with my veterinary colleague to design a preconditioning schedule planning tool to use during conversations with your veterinarian and nutritionist. The goal for using it is to develop the postcalving preconditioning program that works on your farm and meets the expectations of your calf buyer. Most tasks can be accomplished during three handling events with newborn, preweaned and weaned calves. Immediately schedule the corresponding preconditioning dates and tasks once your calf crop is born. Preplanning allows you to have inventory, equipment, labor and your facility ready to process and feed calves. The preconditioning schedule is also available at

Neonatal processing includes identifying the calf, disinfecting its navel and making sure it nurses or is fed colostrum (or colostrum supplement or replacer). Follow your plan to administer vaccinations for newborn and preweaned calves. Castrate and dehorn calves before their third month of age. Vaccine boosters are often given just prior, at or just after weaning. Use equipment or build a facility that will allow you to process calves, often in conjunction with the cow’s life-cycle events (vaccination, breeding, pregnancy checking, etc.).

Weaning periods of 45 days are commonly talked about, and lately, some buyers prefer 60-day weaned calves. This time period starts the day calves are weaned (separated from the momma cow) and fed on the farm for 45 to 60 days prior to their sale date. Using birth records, calculate an average date of birth for your calf crop. The weaning date is then predetermined from that birthday or from the expected sale date. The anticipated sale date is predetermined to reflect business goals or from the calf crop’s birth date. These dates set your calendar of processing tasks.

For example, Farm A has identified the market that will purchase preconditioned calves on March 1. This market’s buyers want 700-pound calves that are vaccinated and fed for a minimum of 45 days postweaning before being marketed. If the calf crop’s average birth date is June 1, when does weaning need to occur? The answer is Jan. 14, based on calf readiness for the sale date. Preconditioning processing tasks can be scheduled for June through January, with postweaning nutrition from January to March enabling calves to reach their desired market weight.

Information from your preconditioning schedule may be transferred to the preconditioning record form. Sharing preconditioning records with potential buyers builds trust in your reputation.
