A kind of cage device for flat raising experiment of animals

Abstract

The invention discloses a cage device for an animal flat culture test. The cage device is constructed by means of splicing at least two cage units on left and right sides, wherein each cage unit is constructed by a rectangular frame body; grid plates are arranged on the top sides, left sides, right sides and back sides of the rectangular frame bodies; grid-shaped transverse-pulling doors are arranged in front of the rectangular frame bodies; rectangular baffle plates are arranged on the inner sides of the transverse-pulling doors in front of the rectangular frame bodies; the lower sides of a left border and a right border are provided with clamping grooves; the two ends of the rectangular baffle plates are embedded into the clamping grooves respectively. According to the cage device, the top sides, the left sides, the right sides and the back sides of the rectangular frame bodies are provided with the grid plates, so that a steel material is saved, mutual concern and communication of caged animals are facilitated, and livestock behavior and welfare are satisfied; meanwhile, environmental factors such as illumination and air speed among cages are coordinated and unified conveniently, and a test person can observe the statuses of the caged animals conveniently; the rectangular baffle plates are used for preventing the caged animals from running outwards when the transverse-pulling doors are open for the test person to add feed or enter and exit.

Description

technical field [0001] The invention relates to a cage, in particular to a cage device for a test of flat raising of domestic (special) poultry animals. Background technique [0002] Indoor scientific research on domestic (special) poultry under the flat rearing model, including comparisons in areas such as chicken, duck and quail production performance testing, breeding density, breeding environment control, feeding management technology, nutritional regulation, and disease prevention and control during the developmental period sex studies. [0003] At present, there is no cage device specially used for carrying out indoor scientific research under the flat raising mode of domestic (special) poultry both at home and abroad. In the past scientific research, in order to ensure the consistency of the number of repetitions and the available small environment in each test group, the ready-made, large-scale fixed pens are generally used, through square bricks, cotton or chemical...

AI Technical Summary

Problems solved by technology

The isolation pens built with square bricks have problems in the control of the consistency of the small scientific research environment, including: ① The isolation room with a temporary gate should not be opened too large, which is prone to animals fleeing; It is inconvenient to open and close the door during the process of entering and exiting and feeding with a heavy hand, and it is easy for animals to escape; It is often more inconvenient when the hands are carrying heavy loads; ③The lower end of the isolation pen is closed, making it difficult to clean up litter and dirt; ④The view between the isolation pens is closed, which affects the behavior and welfare of animals kept in the enclosure, and it is also for researchers to observe Inconvenience; ⑤ The pens are isolated by fully enclosed brick walls, which may cause inconsistencies in the air velocity between the pens

[0005] Temporary isolation pens built with cotton or chemical fiber grids and wooden (metal) grids also have problems in the control of the consistency of small scientific research environments, including: ① The grids are soft and difficult to fix corners, making The floor area is not easy to control accurately; ②In order to save the grid and space, the grid will be shared between the isolation fences, so that there is no or lack of aisles and entrances between the isolation fences, and it is inconvenient for scientific researchers and house animals to enter and exit; ③The isolation fence uses a section It is easy to deform and collapse after a period of time, and it is difficult to guarantee the relative independence and airtightness of the repeated space, and it is easy for animals to escape from the cage; Inconvenient, easy to cause animals to escape cages; ⑤When the airtightness of the lower end of the isolation fence is not enough, it is easy to cause litter to escape from adjacent pens, resulting in errors in scientific research related to litter; at the same time, it can cause ground pollution in the isolation zone or aisle; ⑥ Yes In the large-room fixed pens with water line and material line distribution, after temporary isolation, it is impossible to ensure that the distribution of buckets and drip nipples in each isolation room is consistent

[0006] In addition to the above-mentioned individual problems, the isolation pens built with square bricks and the temporary isolation pens built with cotton or chemical fiber grids and wooden (metal) grids, etc., also have common problems, including: ① Transformation In the barns with no water line and hanging feed line distribution before the transformation, the feed bucket or (and) water bucket can only be placed on the ground, and the poultry has scratching behavior and random excretion behavior, which is easy to cause feed and drinking water to spill and pollute. Cause relevant scientific research errors; at the same time, the spilled feed and drinking water will cause litter pollution, which seriously affects the living and health welfare of animals raised in the house; There are difficulties, and the height, density and distribution of foreign objects are also difficult to be consistent; ③The space of the isolation pen cannot be adjusted with the increase of the age of the scientific research animals; ④It cannot form a three-dimensional closed space, and scientific research related to lighting cannot be carried out, etc.

The isolated pens constructed in this way will not be able to meet the relative independence and consistency requirements of repeated pens within and between groups in various scientific researches, which will bring uncontrollable interference and errors to the scientificity and reliability of the research results.
