ISSUE FOCUS 22 FEED & ADDITIVE MAGAZINE April 2022 TIPS FOR REDUCING STRESS WHEN WEANING CALVES "When you consider the long history of the beef sector, stress is a relatively new issue being examined and discussed by those in the industry. In recent years, scientists and producers have begun to realize the impact that stress can have on calf performance. Fortunately, however, there are solutions for mitigating stress for your cattle during transitions." No matter the segment of the beef system, stress is a natural and unavoidable hurdle that the beef industry must learn to manage. Ironically, it is often the segmentation of the beef system that results in periods of stress. These stressful times often fall around transition intervals, when cattle move from one phase of production to the next. Weaning and feedlot receiving are two transition periods during which calves will experience multiple stressors. Prolonged exposure to stress has negative impacts on calf performance, and these negative effects can result in long-term issues. When you consider the long history of the beef sector, stress is a relatively new issue being examined and discussed by those in the industry. In recent years, scientists and producers have begun to realize the impact that stress can have on calf performance. Fortunately, however, there are solutions for mitigating stress for your cattle during transitions. First, it is important to understand what can cause stress, as well as the consequences of that stress. STRESSORS THAT CAN OCCUR DURING WEANING AND RECEIVING INCLUDE: 1. Separation from the dam The social stress of being removed from the mother can be significant. One management practice that gradually weans calves is fence-line weaning. This technique involves placing weaned calves and dams in adjacent pastures that allow calves to be able see their mothers while being physically separated. Make sure you have sturdy fences with no gaps to prevent calves from crawling through to the other side. 2. Transportation It’s inevitable: At some point, cattle will need to be moved. There are many ways that producers can work to reduce stress during transportation — but similarly to humans travelling to new locations or making a big move, this major transition will likely lead to schedule changes and disruptions, changes in eating patterns, etc. 3. Commingling When groups of cattle are mingled together, they can expose each other to new pathogens. Even if the Dr. Shelby Roberts Ruminant Research Scientist Alltech
