A kind of cage device for poultry growth and metabolism

Abstract

The invention discloses a cage device for growth and metabolism of birds, comprising a frame, an individual cage unit and a movable water line; the frame is a multi-layer structure, and each layer is provided with a movable water line and at least one individual cage Unit; the individual cage unit is installed inside the frame, including the individual grid cage, the suspended bucket-shaped material box and the independent manure tray. The individual grid cage includes 6 cage positions, and the front and rear grids of each cage position are It is equipped with hanging positions of material boxes of different heights. Each cage position is equipped with a grid-type sliding door on the front grid, and an independent manure tray at the bottom. There are drip heads and water cups on the movable water line. The cage position of the invention is designed as an individual cage position, which meets the requirements of the metabolic experiment and saves the test cost. The invention is easy to move, easy to load, unload, and store. Suspended bucket-shaped feed boxes with different heights and movable water lines can be used for domestic animals of different body sizes.

Description

technical field [0001] The invention relates to a cage, in particular to a cage device for growth and metabolism of birds. Background technique [0002] In order to maintain life and health, in addition to sunlight and air, animals must ingest food, and obtain nutrients from food (mainly including carbohydrates, lipids, proteins, vitamins, inorganic salts, water and cellulose). matter and energy to sustain life. It has been confirmed and estimated in studies on the effects of genetics breeding and dietary formulations on chicken performance that 35% of chicken growth is due to breed and 65% to nutrition. Therefore, nutrition plays a key role in poultry breeding and farming that cannot be ignored. With the annual increase in human demand for green poultry food, the research status of the use value and safety of poultry feed nutrients has become prominent, and metabolic experiments are an important means to complete related research. In addition to the related research on p...

AI Technical Summary

Problems solved by technology

The size of the inclined egg or breeding hen cages in the existing laying or breeding hen production yard meets the requirements of individual cages. Although the cost of experimental animals is saved, the inclination of the bottom of the cage seriously affects the growth and development of meat-type poultry. Healthy, not in compliance with animal welfare, not suitable for use in poultry metabolism tests

The size of the flat-bottomed rooster cages in the existing layer poultry or breeding poultry production farms meets the requirements of individual cages, but due to the limited number of cages, no independent manure trays, and scattered locations in the field, there is no need for environmental control and quality control of manure collection. Suitable for avian metabolism testing

[0007] (2) The type of existing cages (generally brooding cages), the size and height of troughs and water tanks, and the firmness of the bottom of the cages cannot take into account the experimental poultry of different ages, sexes, breeds and species, for example: ① Breeding roosters, adult roosters and other animals with slightly larger body weight and body height require that the size and height of cages, troughs, and water tanks are different from those of chickens or other poultry at or before the breeding period, and that the firmness of the bottom of the cage is required to be different. Higher requirements, general cages cannot bear; ② Meat and waterfowl also have special requirements on the size and height of cages, troughs, and water tanks, especially the larger requirements on the diameter and depth of cages, otherwise it will be broken due to the semi-jet type The excrement overflows due to excretion; ③The door area is small, which makes it difficult to put in and grab large domestic animals. At the same time, it is easy to cause scratches on the hands of the staff and damage to animal feathers and skin, etc.

[0013] When the above conditions or problems cannot be effectively solved, it will bring uncontrollable interference and errors to the scientificity and reliability of the results of metabolic experiments.

[0014] In the prior art, there is no cage device specially used for poultry metabolism experiments, and the commercially available independent cages with manure trays (generally broiler brooding cages) are used instead, or through rectangular plastic trays, enamel trays, plastic plates, etc. Or plastic film is placed under the existing or self-made cages to form a temporary and simple feces collection device, which has high test costs, inaccurate collection of feed and drinking water, and difficulty in quality control of feces collection. It is difficult to control the experimental environment, and it cannot take into account the experimental poultry of different ages, sexes, breeds and species, which will affect the scientificity and reliability of the research results.
