In the winter, they eat hay, which they are given in abundance. In some situations where a donkey requires more food (because of labour, lactation, etc.), its feed can be supplemented with mash adapted for horses. A donkey’s diet must be sufficient, but not excessive, as carbohydrate and protein overeating can cause severe metabolic disorders, and obesity is the leading cause of infertility in donkeys.
For their comfort, the donkeys are given freedom of movement and the leisure to socialize with other members of their herd. They are also given access to shelter from the sun and bad weather, and a cool, clean watering point. When a donkey has to be kept in its box stall, and during the winter, it is provided with a clean, comfortable surface where it can rest within its confined environment. Donkeys also dislike being alone and must be kept in contact with a companion while in their box stall.
Basic donkey care, aside from feeding, consists of worming the animals 3 or 4 times a year and trimming their hooves every 2 or 3 months, depending on how fast they become overgrown.
