A device to prevent pigs from fighting

Abstract

The invention provides a device for preventing pigs from fighting. The purpose of the present invention is to provide a welfare preventing pig fighting device, which can reduce or avoid the damage to pigs caused by the fighting behavior caused by the mixed group of pigs in large groups of houses, and further improve the welfare level of pig breeding. The technology of large group house feeding and free-range breeding of pigs is conducive to its application and promotion. The device comprises an aisle support (2), a side plate (3), a rotating 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 in particular relates to a large-group pig breeding and free-range breeding mode. Background technique [0002] With the widespread application of automated, intelligent, and mechanized equipment in pig farms and the advocacy of welfare breeding concepts, the planning and design of farms and breeding techniques are increasingly inclined to the large-group house feeding and free-range farming model. Different from the way of raising individual stalls, when the pigs are mixed in large groups, it usually takes 2-10 days for the unfamiliar pigs to establish a new social hierarchy through mutual competitive behavior. If this process is not managed, it will lead to 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 thei...

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
