FIELD: agriculture. ^ SUBSTANCE: invention relates to agriculture and is intended to keep pigs in pigpen barns at pig farms. A barn for pigs keeping comprises partitions, a gate, a feeding trough, a drinking trough, a system of manure removal and according areas of recreation, feeding, drinking and defecation with grilled flooring, which is separated from other zones by a non-transparent partition. There are passages provided between areas of feeding, recreation and defecation, and their width is not less than twice the animal width. Solid non-transparent partitions that separate defecation area from recreation and feeding areas along the length of not less than the animal length. Height of all partitions and gate of the barn makes at least the animal length. Minimum area of defecation zone is determined using formula SdzÇèmin:=Bs*(3-4)*Ba, and maximum - according to the formula SdzÇèmax=n*qm*T/ht, besides, their ratios are multiple to each other - p=SdzÇèmax/SdzÇèmin, where: n - number of animals in the barn; qm - quantity of manure from one animal; T - time of animals keeping; ht - tray depth; p - number of tray fills; Bs - size of barn side; Ba - animal width. ^ EFFECT: barn makes it possible to reduce stress situations and its contamination due to clear segregation of recreation, feeding, drinking and defecation areas. ^ 1 dwg, 1 ex |
