Michigan 4-H is expanding dairy science education opportunities with a new curriculum designed to help youth better understand calf health and immunity. The educational resource focuses on the importance of colostrum and its role in supporting the growth and development of newborn calves.
The lesson was developed by Paiton McDonald, Michigan 4-H Dairy Program Volunteer and Ph.D. student in Dr. Barry Bradford's lab. The curriculum introduces young learners to the science behind colostrum, helping them understand how it contributes to immunity, gastrointestinal development, and overall calf health.
Colostrum is the first milk produced after a calf is born and contains important antibodies that help protect young animals from disease. Through hands-on activities and experiential learning, participants explore how these antibodies move through the gastrointestinal tract and become absorbed into the calf's body. The lesson emphasizes why providing high-quality colostrum soon after birth is critical for healthy calf development.
Rather than relying solely on lectures, the curriculum encourages active participation and scientific investigation.
Youth are guided through activities that help them explore biological processes, ask questions, think critically, and understand how research-based animal care practices are applied on farms. This approach helps strengthen both scientific knowledge and problem-solving skills.
The resource is designed for use in a variety of educational settings, including 4-H club meetings, 4-H SPIN club sessions, classrooms, and other youth-learning environments. The lesson can be completed in approximately 30 to 60 minutes and is adaptable for different group sizes, making it accessible for educators and volunteers across Michigan.
In addition to supporting youth education, the curriculum serves as an important resource for adult volunteers.
Accompanying PowerPoint slides include detailed speaker notes that provide scientific information and teaching guidance. These materials help volunteers build confidence and improve their understanding of colostrum management while delivering accurate, research-based instruction.
The educational package includes the “Dairy Calf Gut Closure and Colostrum Antibody Absorption” lesson plan and the “Understanding the Importance of Antibodies and Colostrum” PowerPoint presentation. Together, these resources support high-quality dairy science programming and promote greater understanding of animal health management.
Michigan 4-H believes that science-based learning experiences can inspire youth to explore careers in dairy production, veterinary medicine, animal health, and agricultural research. By connecting classroom concepts with real-world agricultural practices, the program helps prepare future leaders in agriculture.
Through innovative educational resources and hands-on learning opportunities, Michigan 4-H continues to support youth development, encourage lifelong learning, and strengthen awareness of the science that drives successful animal agriculture.
