Is weaning something you dread so much that you just want to put the calves on a truck and let the buyer worry about it? Do you avoid weaning your calves because you think you don’t have adequate facilities? Does weaning seem like just too much work? Would you be interested in a reduced-stress method for weaning calves? If you answered “yes” to any of these questions, you should consider fence-line weaning. It is a lowstress, minimum-facility, low-labor procedure that is being used by many producers across the country.
The traditional method of weaning is complete separation of the calf from its dam with no interaction. You could call this an “out of sight, out of mind” approach to weaning. This puts tremendous stress on the calves, however, causing them to bawl for several days, walk the fence, not eat and not gain weight. This publication describes fence-line weaning, summarizes recent research showing its benefits, and acts as a worksheet for producers who would like to implement a fence-line weaning system.
The name, fence-line weaning, pretty much describes itself. Calves and their dams are simply weaned from one another across a fence line so they remain in sight of one another and in earshot (Fig. 1).
Fence-line weaning separates cows and calves using either a permanent or temporary fence. With proper pasture management, calves have access to good quality grass, ideally up to 60 days. Minimizing housing and dietary changes reduces stress. Keeping the cattle on pasture promotes uninterrupted feed intake and weight gain while meeting the nutritional needs of both growing calves and non-lactating cows. In the ideal situation, the only nutritional change for the calf is the loss of a small amount of milk.
Recent research from the University of California, Davis, found that weight gain during the First 2 weeks after weaning improved by 95 percent in calves that were fence-line weaned compared with calves that were completely separated from their dams. After 10 weeks, fence-line-weaned calves had gained 31 percent more weight than traditionally weaned calves (Figure 2). The study also found that calves that were fence-line weaned did not go off feed at weaning, bawled less, spent less time pacing the fence and spent more time lying down. If you can sell heavier weaned calves that are bunk broke, your calves will have an edge in the marketplace over calves that are bawling, stressed and just waiting to get sick.
Keys to Fence-line Weaning
Use at least three strands of electric wire or one hot wire standoff from a standard fence such as woven wire (Figure 3). You should have a minimum of 2,500 volts of charge to make sure the calves don’t get through. It is a good idea to train the calves to a hot wire before weaning. Run one strand along an existing stretch of fence and let them get used to it. Let them find out what that voltage will do.
The second key is good grass. High quality pasture can be promoted with intensive rotational grazing management. Start planning before the grazing season begins (Table 1). For more information on intensive grazing, refer to MSU Extension bulletin E-2288, Controlled Grazing: Balancing Forages, Livestock & Management. This bulletin can be acquired at your local county extension office or on the web at www.emdc.msue.msu.edu.
Here is a timetable to help you plan for your fence-line weaning (Table 2).
Fence-line weaning can provide many benefits for your operation. It increases your marketing options as a cow/calf producer because you can sell a calm calf that is bunk broke and has the potential to perform well in a backgrounding or feedlot operation. If you consider that cattle feeders want to buy calves weaned and vaccinated and you, a cow/calf producer, want to sell as many pounds as possible, fence-line weaning makes sense. You can add pounds to your calf crop without additional cows and with minimal investment in time, equipment and money. Less stress on the calves and more pounds to sell might just reduce your stress level as well.
