Description

technical field [0001] The invention belongs to livestock breeding facilities, in particular to a semi-limited breeding pen for group-raised livestock. Background technique [0002] Breeding of livestock in positioning pens restricts the free movement of livestock and the behavior of expressing their biological characteristics, so long-term confinement will lead to negative physical, psychological or physiological effects on livestock, while livestock raised in groups will not restrict the above-mentioned behaviors, but the group There is a hierarchy among domestic animals. In order to compete for resources, such as food and resting places, the strong will attack the weak, so it will affect the welfare of individuals in the livestock group, especially the weak. Therefore, while keeping livestock in groups, it is necessary to protect the individual from being attacked or disturbed by other individuals while satisfying the freedom of individual activities. In the small group ...
