Weaning marks a pivotal moment in the life of a beef calf, but it's also one of the most stressful.
At 6 to 8 months, beef calves undergo a series of stressors including separation from their dam, castration, vaccination, dehorning, exposure to new environments, changes in feed and water sources, and weather fluctuations - particularly for spring-born calves. These stressors, either individually or combined, can significantly challenge the calf's health, growth and performance. As a cattle producer, your management strategies during this critical period can make all the difference in the short-term and long-term success of your operation.
Here are some essential tips for navigating the weaning process (before, during and after) effectively:
Pre-weaning management plays a crucial role in preparing calves for the challenges of weaning. Ensuring optimal nutrition is key, as it directly impacts the calf's ability to mount an immune response to vaccinations and cope with the stress of weaning. A balanced diet rich in protein, energy, minerals and vitamins sets the stage for healthier, more resilient calves. Vaccination is a critical component of pre-weaning management. Administering vaccines two to three weeks before weaning allows calves to develop immunity before facing the stress of separation from their dams.
To minimize stress during weaning, it is also advisable to perform procedures such as castration, dehorning and branding before the actual weaning process begins. This approach reduces the cumulative stress experienced by the calf and promotes a smoother transition.
There are three main weaning strategies to consider, each with its advantages and disadvantages:
Careful grazing management is essential during and after weaning to accommodate both cows and calves. For calves, overall nutritional management plays a vital role in mitigating the impact of stress during and after the weaning process. By selecting feeds with high palatability and digestibility and carefully managing the introduction of energy-dense grains, producers can ensure that transitioning calves receive the nutrients they need to thrive.
Providing unrestricted access to clean water is also paramount for the health and well-being of recently weaned calves.
When choosing a weaning strategy, consider the specific needs and dynamics of your operation. Consult with your veterinarian to determine the best approach based on factors such as herd size, facilities, and available resources.
