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. Background technique [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...

[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 anim
