This is also evident in practice. Deer farmer De Weerd states in the Nederlands Dagblad: “A deer never becomes tame. Does that roam freely outside may appear calm, but they panic if I make an unexpected movement. “Catching is actually best achieved with a tranquilizer gun.” ^[7]

Living conditions on a deer farm are significantly different from those in the wild. The farm features several fenced pastures and winter stables. The pastures accommodate 20 to 25 deer per hectare, which is over 200 times smaller than their natural habitats. ^[8]

Near the stables, there is also a treatment area equipped with a deer crush. This device securely holds the animals between two walls. Since deer are wild animals, it is not feasible to carry out veterinary procedures on them without restraint, such as blood collection or deworming. The crush is also used for, among other things: to prepare stud bucks before sawing off their antlers. ^{[9] [10]}

Female breeding deer give birth to a calf in May or June. Mothers and calves spend the summer together in a pasture. In autumn, when the calves are 4 to 5 months old, they are separated from their mothers, even though they would naturally stay with them for two years. The calves are then grouped together to grow until they are 18 months old. At that point, some of the female calves are chosen as new breeding mothers, while most of the calf group is slaughtered for their meat. Mother animals are used for breeding for about 7 years. ^{[11] [12]}
