E122 The Energy Efficient Dairy Cow: Leveraging Genetics and Nutrition for Sustainable Dairy Farming

Can genetics and nutrition boost the energy efficiency of lactating cows? A study from the University of Nebraska-Lincoln revealed that differences between Jersey cows significantly affect energy use, especially in methane and tissue energy. These differences account for 29.3% to 42.5% of the energy variance, highlighting the role of genetics and diet in making cows more efficient. With 115 Jersey cows and over 560 data points, the study shows that focusing on genetic selection and nutrition can enhance productivity and sustainability in dairy farming. By understanding these factors, farms can reduce emissions and improve milk production, paving the way for a more eco-friendly future for the dairy industry.
