Abstract

Equid milk is arousing increasing interest in consumers and researchers because of its similarity in composition to human milk. The low and different protein content makes equid milk it suitable for children with cow milk protein allergy. Both horse and milk production, in many farms, still follow a characteristic and traditional method of separating the foal from the mother to allow milking procedures. This separation lasts at least 2 to 3 h before milking, a time in which the foal remains fasting. This operation is repeated several times a day, as the equid udder has little collection capacity, and milking frequency is one of the most important parameters to increase milk production; it must be emptied often. New partial artificially suckling techniques have been developed that allow the foal to be separated from its mother for many hours without starving. Furthermore, mechanical milking has been introduced in equid milk production, although in-depth knowledge is lacking on milking parameters and how these aspects affect milk production and udder health. Moreover, in some farms, new milking parlors for Equidae have been developed, ensuring that stress is minimized and production and animal welfare are ensured. It is important to develop and apply technologies for equid milk production, evaluating potential effects on welfare, health, and milk production. This represents the broadest perspective and the greatest challenge because of the need to understand management best practices, thinking to the possibility to introduce as soon as possible automatic milking systems that could ensure a good milking frequency.
