Light environment preference selection detecting system for livestock and poultry

Abstract

The invention relates to a light environment preference selection detecting system for livestock and poultry. The light environment preference selection detecting system for the livestock and poultry is characterized by comprising an outer frame, a plurality of sealing separation plates and a data acquiring and processing system. The outer frame is separated into a plurality of detecting units by the sealing separation plates, a bottom seat of each detecting unit is fixedly connected with a bottom net weighing device, the top of each bottom net weighing device is fixedly connected with an internal frame, each internal frame is fixedly connected with a waterer and a camera, the sealing separation plates for every detecting unit are movably connected with an excrement bearing drawer, the bottom seat and a top plate of each detecting unit are fixedly connected with a forcing fan, the top plate of each detecting unit is fixedly connected with a light tube, a front end side plate of each detecting unit is fixedly connected with a crib weighing device, each crib weighing device is fixedly connected with an egg belt, a top portion of each crib weighing device is fixedly connected with a crib, and the data acquiring and processing system is electrically connected with the bottom net weighing devices, the cameras and the crib weighing devices. The light environment preference selection detecting system for the livestock and poultry can be widely applied to light environment preference selection experiments for the livestock and poultry.

Description

technical field [0001] The invention relates to a detection system and a method for selecting a preferred light environment for livestock and poultry, and belongs to the field of detection and control of facility agricultural environments.

[0002] In commercial livestock and poultry houses, the introduction of artificial light sources greatly improves the production performance of livestock and poultry, but at the same time, due to the lack of consideration from the perspective of the needs of livestock and poultry, there are also many health and welfare problems for livestock and poultry living under artificial light sources. The problem is that the light environment selective preference experiment is to provide various light environment conditions for livestock and poultry. Livestock and poultry can freely choose according to their own needs and preferences. It is studied through the selection of livestock and poultry to the environment, the difference in preference, and the likes and dislikes of livestock and poultry. Animals have their own needs. Animals have the instinct to maximize their own welfare, so they will choose the conditions that best meet their own needs. A well-designed environmental preference selection system is important for obtaining high-quality data and reliable experimental results. Therefore, designing a preference testing system that can provide research conditions for special research purposes and can monitor continuously for a long time is an essential part of preference research. There are few equipments for research on the choice of light environment preferred by livestock and poultry

[0003] In order to study the preference of laying hens to different ammonia concentrations, Kristensen et al. improved the octagonal ring-shaped closed preference box designed by Jones. The advantage of this octagonal preference box is that it can provide animals with sufficient alternative environments. There are 8 The unit can do 2 repeated experiments of 4 factors. The preference box is in a ring shape. Animals can reach each testing unit to fully contact with different environments and then make choices. However, this design is not completely closed. Cleaning requires the animals to be removed and then cleaned. The operation is complicated. It is unfavorable for the continuous detection of some animals that are sensitive to changes in the light environment. For example, laying hens are light-sensitive animals, and the airtightness of the environment is required in the light test. , if the chicken is moved out and in during the test, it will inevitably be exposed to the external light environment, which will affect the test results

[0004] For researching the preference of laying hens to light, prior art discloses a kind of square preference box, the advantage of this preference box is that it can provide sufficient optional airtight environment for animals, this design has 5 units, preference There are small doors between the boxes for animals to reach, and the selection is made after each detection unit is in full contact with different environments. At the same time, the outside of the preference box is covered by partitions to prevent interference from the external environment. However, there are many problems in this system : 1) The conveyor belt and the egg collection belt connect the 5 units through the bottom, causing the problem of light leakage at the bottom of the unit and the unit. The livestock and poultry in this compartment can also feel the light of the next compartment. Even if the livestock and poultry prefer the next compartment The light environment may not enter the compartment, which will interfere with the light environment test results

2) The bottom of this preference box is fixed and has a slope. It can only be used for the test of laying hens in the laying period. Ground breeding can not meet the test requirements of other small livestock and poultry that need flat ground, so it is not universal

3) The sliding door used for feeding at the front end of the preference box will generate a lot of noise, and manual operation will greatly interfere with livestock and poultry, which will easily cause stress. At the same time, due to the high sliding height and large exposure area, it will negatively affect the test results influences

4) The behavior recognition method of this preference box is image processing. This method is not timely for behavior processing after the test, and the sampling time is short (the data volume is only 3 days). Manual calibration is required, and real-time continuous monitoring cannot be performed. Not conducive to obtaining reliable test data
