sow positioning pen

Abstract

The invention relates to a sow positioning fence. The sow positioning fence comprises a positioning fence front door, a positioning fence rear door, lateral positioning fence bodies and positioning fence pressing rods, wherein the positioning fence front door and the positioning fence rear door are connected with the lateral positioning fence bodies through latches respectively; a basin and a manger are arranged below the positioning fence front door; a horizontal bent tube is arranged on the top of each lateral positioning fence body; a horizontal straight tube is arranged on the bottom of each lateral positioning fence body; a vertical support is arranged between each horizontal bent tube and the corresponding horizontal straight tube; a small rotating sleeve is arranged on each vertical support; a biting toy rotating shaft is arranged between the two small rotating sleeves; a biting toy is arranged on the biting toy rotating shaft; a transverse support is arranged in the middle of each vertical support; a large rotating sleeve is arranged on each transverse sleeve; a rubbing rotating shaft is arranged between the two large rotating sleeves; and a rubbing unit is arranged on the rubbing rotating shaft. The biting toy and the rubbing unit are arranged on the lateral positioning fence bodies and are playing facilities of sows, behaviors and amount of exercises of the sows are increased, demands of rubbing, pushing, biting, playing and the like of the sows are met, and benefits of the sows are improved.

Description

technical field [0001] The invention belongs to the technical field of breeding equipment, and in particular relates to a positioning stall for sows which can improve the welfare of sows. Background technique [0002] With the vigorous development of my country's pig industry, the degree of intensification and scale is increasing. In order to reduce the land occupied by pig raising, the mechanized feeding of sows has become a fixed trend. From the perspective of sow breeding in large-scale pig farms, most The pig farm adopts sow positioning breeding, that is, limited pen breeding. Compared with free-range breeding of sows, sow positioning pen has the advantages of easy management, high stocking density, and prevention of pigs fighting. However, the existing Due to the limitation of the position of the sow positioning pen, the single structure of the limit pen violates the biological characteristics of the pig. Because the sow lives in a fixed and small space for a long time, i...

[0002] With the vigorous development of my country's pig industry, the degree of intensification and scale is increasing. In order to reduce the land occupied by pig raising, the mechanized feeding of sows has become a fixed trend. From the perspective of sow breeding in large-scale pig farms, most The pig farm adopts sow positioning breeding, that is, limited pen breeding. Compared with free-range breeding of sows, sow positioning pen has the advantages of easy management, high stocking density, and prevention of pigs fighting. However, the existing Due to the limitation of the position of the sow positioning pen, the single structure of the limit pen violates the biological characteristics of the pig. Because the sow lives in a fixed and small space for a long time, it lacks exercise and hinders the performance of the basic behavior of the pig. , such as turning around, walking, foraging, scratching, arching, biting, social interaction, etc. Pregnant sows in stalls are not only prone to hunger, but also prone to abnormal behaviors such as empty chewing, biting, excessive drinking, etc., and even cause physical Loss and reproductive diseases that lead to prolonged farrowing, dystocia, dyspepsia, reduced performance, etc.
