Habitat type laying hen breeding frame

Abstract

The invention relates to a poultry cultivation frame and particularly provides a roost type laying hen cultivation frame. The roost type laying hen cultivation frame comprises a plurality of feeding layers (1), supporting rods (2), roost rods (3) and connection rods (4), wherein the plurality of feeding layers (1) are provided with stand columns (11); the supporting rods (2) are parallel to the stand columns (11); the roost rods (3) are horizontally arranged on the supporting rods (2), and the two connection rods (4) are parallel to each other; one end of each connection rod (4) is movably connected with the corresponding stand column (11) through a first pin point (41); the other end of each connection rod (4) is movably connected with the corresponding supporting rod (2) through a second pin point (42); and a locking mechanism (5) is arranged between each stand column (11) and the corresponding connection rod (4). By virtue of the roost type laying hen cultivation frame, the distance between each roost rod and the corresponding feeding layer can be changed according to the requirements of a feeder so that the feeder can conveniently get close to the feeding layers to carry out operation, and the distance between each roost rod and the corresponding feeding layer can be adjusted according to the flying capabilities of laying hens with different day ages, so that the requirements of the laying hens with the different day ages are met.

Description

technical field [0001] The invention relates to a poultry breeding frame, in particular to a perch-type laying hen breeding frame. Background technique [0002] At present, the large-scale laying hen breeding method in my country is mainly cage breeding. The cage system has multi-layer feeder layers, and the surroundings are closed with side nets. The feeding, drinking, and laying behaviors of laying hens are all in the same plane, which cannot meet the requirements of the natural habit of laying eggs in high places and dark places. At the same time, chickens cannot move freely in a small space, and cannot freely express behaviors such as nesting, sand bathing, perching and combing feathers, which makes their body resistance poor and their health status poor. Based on the protection of animal welfare, the European Union has banned laying hen cages in January 2012. Free-range breeding in large-scale facilities is an important measure to solve animal welfare problems, but fr...

AI Technical Summary

Problems solved by technology

The support bar 2 is connected on the column on the open side of the feeding layer, and a plurality of roosting bars 3 are horizontally arranged on the support bar 2 at a certain interval, because the connecting bar 4 is fixed between the column 11 and the support bar 2 and cannot rotate. Therefore, the distance between the perch bar 3 and the feeding layer 1 is fixed. When the breeder approaches the feeding layer 1, the perch frame 3 is separated, which is inconvenient to operate and increases the difficulty of management, and the perch bar can only be set according to the spacing when the laying hens are adults. 3 and the distance between the feeding layer 1 cannot be suitable for the activities of young laying hens. If the distance between the perching rod 3 and the feeding layer 1 is reduced by increasing the perching rod between the column 11 and the perching rod 3, it will satisfy If the requirements of small day-old chickens with weak flying ability are required, adult chickens with strong flying ability will be restricted when flying up and down or jumping, which is not conducive to expressing the behavior of adult chickens, so this kind of breeding rack cannot be suitable for the activities of laying hens of different ages
