Automatic milking systems (AMS) have been associated with various milk quality problems. Today, several problems are solved. One of the problems still existing is a high concentration of free fatty acids in milk from AMS compared with conventional systems. The present study shows that cooling of the milk in a plate cooling exchanger close to the milking unit decreases the formation of free fatty acids (FFA) in milk, and a rapid cooling of the milk before pumping over long distances will be a suitable solution to improve milk quality in AMS systems. Furthermore, a review of milk quality parameters, such as somatic cell counts (SCC), total plate counts (TPC) and freezing point from AMS is presented.
