Device capable of preventing pigs from fighting

Abstract

The device provides a device capable of preventing pigs from fighting and aims to provides the welfare device capable of preventing the pig from fighting .The device reduces or avoids harm to pigs due to fighting behaviors caused by mixed groups in a free-ranging large hoggery, enhances a welfare grade of pig breed, improves free-ranging technology of a large free-ranging pig hoggery, and is beneficial to application and popularization of the device. The device capable of preventing the pigs from fighting comprises a aisle support (2), a side plate (3), a rotary plate (1), a first toy device (5), a second toy device (6) and a third toy device (7).

Description

Technical field [0001] The invention belongs to a welfare device for pig production, and particularly relates to a mode of raising pigs in a large group house. Background technique [0002] With the widespread application of automated, intelligent, and mechanized equipment in pig farms and the advocacy of welfare-based breeding concepts, the planning and design of breeding farms and breeding techniques have become more and more inclined to the mode of large-scale breeding and free-range breeding. Different from the way of individual feeding in the restricted pen, when the pigs are mixed in the large group house, it usually takes 2-10 days for unfamiliar pigs to establish a new social hierarchy through mutual competition. In this process, if it is not guided, it will cause problems such as increased skin injuries, increased cortisol concentration, decreased production performance, and even paralysis and death of pigs. In addition, the mixed herd of pregnant sows can also affect t...

AI Technical Summary

Problems solved by technology

If not managed during this process, it will lead to problems such as increased skin injuries, increased cortisol concentration, reduced production performance, and even paralysis and death of pigs

In addition, the mixed group of pregnant sows can also affect the behavior and stress response of their piglets, thus seriously affecting pig production.

[0003] Although the prior art has announced a kind of anti-fighting toy for pigs (Chinese patent application CN203226137U), it does not have lasting attraction to pigs because of its simple structure.

At the same time, there is no space for pigs to escape when fighting

U.S. Patent (No.897413) discloses a door for the door of an animal-raising cage that can be automatically locked or bolted, especially for pig cages (Automatic locks or bolts for the door of an animal-raising cage, especially of a cage for raising hogs), although this kind of door can realize the free entry and exit of livestock without manual operation, and can prevent livestock from being disturbed and attacked by other livestock, but this kind of door is only suitable for sow single-pen breeding technology
