Global demand for milk and other dairy products continues to grow. As a result of this increased consumer demand, the sector's greenhouse gas (GHG) emissions have risen dramatically. It is therefore crucial that the livestock sector reacts to these developments and considers areas for improvement that could reduce the sector's contribution to climate change. Advances in sustainable dairy cattle nutrition provides a comprehensive review of the wealth of research on recent advances in understanding and improving dairy cattle nutrition to reduce the carbon footprint of the dairy sector. This collection explores the role of nutritional requirements in optimising gut function and overall animal health, as well as its influence on milk yield and quality. Chapters also review the use of dietary supplements, such as plant extracts and direct-fed microbials (DFM) to optimise dairy cattle nutrition.
