Automated milk feeders (AMFs) have revolutionized dairy farming by precisely managing Holstein calves and enhancing their resilience to environmental stressors. A study of over 10,000 calves identified genetic traits like recovery time, heritability, amplitude, perturbation time that correlate with improved stress responses, particularly against bovine respiratory disease. Despite lower than anticipated genetic influence, these traits highlight opportunities for selective breeding. AMFs enhance calf care and save labor by monitoring milk intake, allowing timely intervention for health issues and optimal nutrition. The trend of genetic selection for resilient calves promises long-term benefits for animal health and farm productivity. Although limited by single-farm data, this research paves the way for breeding programs focused on resilience, aiding in future-proofing global dairy operations. Collaborative efforts integrating advanced technologies with traditional methods are essential for the dairy industry to implement these findings effectively.
