A kind of sow barn feeds loose-feeding piggery sty

Abstract

The invention discloses a feeding and free-ranging pigsty of a sow house, which belongs to the field of livestock feeding facilities. The feeding and free-ranging pigsty of the sow house mainly comprises a pigsty main body, a solid ground, a leaking ground, corner columns, a piglet crushing prevention member, a piglet insulation can and a black non-transparent permeable soft material, wherein the pigsty main body is surrounded by a double-layer fence and a single-layer fence and is fixedly connected by the four corner columns, the solid ground is arranged on the ground which is close to a door of the single-layer fence on the front side, the leaking ground is connected with the solid ground, one end of the black non-transparent permeable soft material is connected with a rotating shaft, and the other end of the black non-transparent permeable soft material is hung between an outer fence and an inner fence of the double-layer fence. According to the feeding and free-ranging pigsty, a quiet delivery environment can be provided for sows, the still birth rate of piglets can be reduced, the crushing rate of the piglets can be reduced, the neonatal piglets can be kept warm, the survival rate of the piglets is increased, and the welfare of the sows and the piglets is considered. Additionally, the feeding and free-ranging pigsty has the advantages of simple structure and high practicability.

Description

technical field [0001] The invention belongs to the field of livestock breeding facilities, and in particular relates to a barn for feeding sows and feeding pigs. Background technique [0002] Wild boars will leave the group before giving birth, choose a secluded place as a delivery location, and build a nest here so that they will not be disturbed by other animals during delivery, and the delivery can be completed quietly, and at the same time, it can better protect the piglets from the cold and attack by other animals. In fact, this maternal behavior has been maintained despite the fact that domestic pigs have been domesticated. However, in the process of intensive and large-scale breeding, although individual feeding is adopted, the behavior will not be disturbed by peers, but it is difficult to prevent the visual communication between sows due to the usual single-layer fence, which in turn causes interference. It is difficult for sows to obtain a quiet environment to c...

Problems solved by technology

However, in the process of intensive and large-scale breeding, although individual feeding is adopted, the behavior will not be disturbed by peers. However, it is difficult to prevent visual communication between sows due to the usual single-layer fences, which in turn cause interference. It is difficult for sows to obtain a quiet environment to complete farrowing, resulting in long labor and long intervals between piglets, which ultimately greatly increases the stillbirth rate of piglets

Directly covering the fence with black opaque material can block the visual communication between sows, but the black opaque soft material covered on the fence is easy to be bitten by sows in labor

Physical pig pens such as brick walls can avoid visual communication and the interference caused by them, but physical pig pens will affect the smoothness of ventilation in pig houses in summer or in areas with relatively hot climates, resulting in high temperature stress reactions for laboring or lactating sows

At present, lactating sows are generally kept in farrowing stalls. Due to the small space in the farrowing stalls, it is difficult for sows to turn around, their behavioral needs cannot be met, and the maternal nature of sows is seriously degraded.

Liberating the sows into a free-moving pen overcomes the inherent defects of the farrowing crate, but increases the risk of piglets being crushed to death by the sow due to the large space
