Use of poultry breeding equipment-Chicken cages are the necessary equipment and methods for breeders to carry out breeding of laying hens and broilers, and they are also the basic equipment for farmers to achieve intensive and large-scale breeding. The use of chicken cages for laying hens and broilers can increase the number of breeders and facilitate the management of breeding. If you want to use this method to breed eggs and broiler chickens, let’s first understand the structure and composition of the equipment, and let’s introduce the structure and composition of poultry breeding equipment-chicken cages to farmers.
The chicken battery cage is mainly composed of a front net (also known as a feeding net), a rear net, a top net, a bottom net, and a partition net (or side net), and the relevant nets are connected and fixed with a cage card. In order to facilitate manufacturing, installation and transportation, the front net and the top net are often made into one body, the rear net and the bottom net are made into one body, and the partition net is made separately. Body length, width, and normal standing height of chickens), cage feeding density, average feeding width, and number of chickens per cage.
1. Front net and cage door: flocks feed and drink through the front net. Therefore, the main structural parameter of the front net is the longitudinal wire spacing. Requires chicken heads to move freely, but not to run chickens. Chickens enter and exit the cage through the cage door on the front net. There are four types of cage doors: (1) The entire front net is turned around the upper fulcrum into the cage. (2) The front net (or half of the front net above the water tank) is turned around the lower fulcrum to the outside of the cage. (3) The cage door opens vertically upwards. (4) The cage door is located in the upper half of the front net (ie above the water tank and the feeding trough).
2. Bottom net: The main structural parameter of the bottom net is the grid size. If the chicken can stand stably, the chicken manure can leak down smoothly. For the laying hen cages, the eggs should not be caught by the grid. First, in order to make the chicken stand stably, the denser the grid, the better, but too dense the chicken manure is not easy to leak down, and the manufacturing cost is also increased. Therefore, the density of the grid is based on the principle that one chicken claw can hold more than two wires at the same time when the chicken is standing normally.
3. Top net: chicken heads should generally be allowed to stick out of the cage, but chickens should be prevented from running out of the grid of the top net. Therefore, the grid size should be larger than the head of the chicken and smaller than the width of the back of the chicken.
Separated nets and rear nets: These two nets are used to limit the range of chickens to prevent fighting between adjacent two cage chickens. For this reason, the weft of the net should be denser so that the chicken head cannot be extended, and the warp can be thinner to reduce the cost. For full or half stepped chicken cages, adjacent chicken cages are arranged behind the lower cage body. The design of the rear net can refer to the design principles of the top net.
4. Cage card: Cage card is used to fix two meshes adjacent to the cage. Generally, it is made of thin steel plate. The cage card is too soft. Under the condition of bearing heavy objects, the two meshes connected to each other will be disengaged and cannot be used for fixing. The cage card usually uses a steel plate with a thickness of 0.8 mm and is punched into a steel strip with a width of 6-8 mm. The length is determined by the diameter of the steel wire and the number of steel wires. The steel strip should be bent into a certain arc in advance to facilitate installation.
