Abstract

The study explores the benefits of eliminating concentrate feeds in dairy cow nutrition. As sustainability becomes a central concern in agriculture, zero-concentrate feeding offers a promising solution to reduce the environmental footprint of dairy farming while promoting optimal animal health and welfare. This approach primarily focuses on maximizing the use of high-quality forages, such as grasses and legumes, to meet the nutritional needs of dairy cows. By minimizing the use of concentrates, the system aims to lower greenhouse gas emissions, reduce dependency on external feed inputs, and encourage more sustainable farming practices. The paper examines the effects of zero-concentrate feeding on milk composition, highlighting improvements in fatty acid profiles, including higher omega-3 and conjugated linoleic acid (CLA) concentrations. Additionally, it addresses the positive impacts on animal health, particularly in terms of improved rumen function, reduced metabolic disorders, and enhanced immune responses. The welfare benefits of this feeding strategy are also discussed, including better behavioral expression, reduced stress, and improved reproductive efficiency. By aligning with organic and regenerative farming principles, zero-concentrate feeding systems support long-term sustainability in dairy farming, offering a holistic approach that benefits both the environment and dairy cows. This study emphasizes the importance of integrating zero-concentrate feeding into future dairy management practices for a more sustainable and ethical dairy industry

Keywords: Animal welfare, dairy cows, environmental sustainability, forage-based diet, milk quality, rumen health, zero-concentrate feeding
