Description

Dairy feed has direct and indirect impacts on the safety of milk and milk products; feed also has implications for animal health and welfare, and the profitability of the dairy sector. This chapter starts with a brief outline of the role of feed in dairy cattle diets, emphasizing the common hazards associated with different feed ingredients. We outline the impacts, diagnosis, governance and management of feed contaminates in general. We then review identification, diagnosis and prevention of some of the most important dairy feed hazards, namely aflatoxins, Salmonella bacteria, persistent organic pollutants, veterinary drug residues and heavy metals.
