What should be done to enhance the immune system of calves before weaning?

1. Delay weaning as long as possible

2. Provide a high-stress environment

3. Implement preconditioning techniques

4. Randomize feeding practices

The correct answer is: Implement preconditioning techniques

To enhance the immune system of calves before weaning, implementing preconditioning techniques is essential. Preconditioning refers to a series of management practices that are applied to calves prior to weaning, aimed at reducing stress and improving health outcomes. These practices can include vaccinations, nutritional management, and socialization with the herd, all of which help calves adapt more effectively to the stresses associated with weaning. By focusing on building the calves' immune systems through these proactive measures, producers can help minimize health issues, reduce morbidity, and support better growth rates post-weaning. In contrast, delaying weaning could potentially extend the risk of disease transmission and stress related to living alongside multiple age groups. A high-stress environment can compromise immune function and lead to higher susceptibility to diseases. Randomizing feeding practices does not provide the consistent nutritional support critical for developing a strong immune response, which is crucial during the early stages of development.
