Background
The poultry pathway for sensing external light stimulation mainly comprises hypothalamic light receptors and retinal light receptors, so that light signals are converted into biological signals, and the pituitary gland is further influenced to release hormones to regulate the daily activities and growth and development of the body. The poultry retinal photoreceptor cells comprise 3 major classes and 6 subclasses. The first type is 4 single cone cells, and can adjust the color perception capability of the poultry, so that the poultry can perceive light which cannot be perceived by human beings, such as ultraviolet light; the second type is a double-cone cell which can sense the motion information of an object; the third type is rod cells, which can sense changes in light intensity under low light. Compared with human beings, birds such as chickens have more visual functions by adding one more cone cell, so that the birds are more sensitive to light environment changes.
In recent years, with the increasing interest in animal welfare breeding, the research on animal behaviors is more and more important. Wherein color recognition of poultry is increasingly a hot spot in the light information perception of animals. Birds and humans are animals that are currently known to classify colors autonomously, but color recognition is not only related to recognizing the color of an object, but also closely related to the light color and illumination intensity of ambient light, and even affected by ambient sound and spouses. In the field of bird research, it has been proved that the color and brightness of eggshell are important to the host bird to eliminate the eggs of the parasitic bird, so that the color difference between visible objects plays an important role in the identification of the target object of the bird. Under specific ambient light, birds cannot recognize when the color difference between two objects is reduced to a certain degree. In addition, the illumination intensity of the ambient light has influence on the color of the bird recognition object, and even the color recognition has the lowest threshold requirement on the illumination intensity of the ambient light.

Wherein the height from the ground is set to 18cm, which simulates the eyeball height of poultry when walking normally.
By adopting the detection device, the detection process is divided into three parts of adaptation, training and testing in sequence.
1) The method is suitable for the following steps:
placing red photographic paper with RGB (255,0,0) color and yellow photographic paper with RGB (255, 0) color, illuminating ambient light through the square adjustable LED light source 4, and placing each poultry into the detection wooden box 1 in sequence for a period of time to enable each poultry to adapt to the internal closed environment, so that the influence of stress on detection is reduced.
The adaptation is divided into adaptation to the culture environment and adaptation to the detection environment.
Several poultry with the same body type are selected and are randomly divided into several groups according to different illumination intensities or light colors for feeding. Because poultry used in experiments are generally in captive breeding, stress is easily generated when the poultry is just changed to a new environment, and subsequent ethological detection can be influenced. Sufficient feed and water are provided each day during the cultivation to make it sufficiently adapted to the new cultivation environment, and this period lasts about 3 days.
The adaptation of the test environment was then carried out in a dark room, with the aim of keeping the birds from fluttering and whistling inside the wooden boxes. Placing red photographic paper with RGB (255,0,0) color and yellow photographic paper with RGB (255, 0) color, illuminating ambient light through the square adjustable LED light source 4, and placing each poultry into the detection wooden box 1 in sequence for a period of time to enable each poultry to adapt to the internal closed environment, so that the influence of stress on detection is reduced. Each bird was acclimatized 1 time per day for 10min for 2 days. At this time, a very small number of birds may peck the slot with the red photographic paper and press the electric switch to push the feed box into the slot for the birds to eat.
2) Training:
before training, the birds were starved.
2.1) training in the early stage:
on the first day, a feed is pasted on the surfaces of two color photographic papers 5 by using adhesive tapes, a little feed is placed in a feed box 7, the feed can be pushed into the feed box by an automatic push rod to be pecked by poultry, and the poultry is trained to recognize red photographic papers by a food rewarding method: as shown in fig. 2, when the poultry pecks red photographic paper as detected by the pressure sensor, the electric push rod 8 pushes the feed box 7 through the horizontal trough and into the detection wooden box 1 for the poultry to peck feed 4s, then the electric push rod 8 pulls the feed box 7 to move out of the detection wooden box 1 so that the poultry cannot peck feed, and the detection wooden box 1 is automatically pushed out after a set time; when the poultry pecks the yellow photographic paper, the electric push rod 8 does not work and no feed is rewarded; if the birds peck elsewhere, they continue to wait for their response.
Each bird is trained for 5-15min each day, which lasts for about 2 days, during which birds that have not performed the action of pecking the slot with the red photographic paper are removed. Until the birds had correctly identified the red paper 3 times, the feed on the surface of the two colored papers 5 was removed, and each bird was then post-trained.
2.2) later training:
blocking the two color photographic papers 5 by using a piece of second black PVC background cloth 3, rapidly removing the second black PVC background cloth 3 after changing or not changing the positions of the two color photographic papers 5, observing the reaction of the poultry to the two color photographic papers 5, and judging whether the red photographic papers are identified and pecked; repeating the training until the poultry can continuously recognize the red photographic paper for 10 times and then completing the training of the day; wherein 10 exercises require that the position of the red photographic paper be changed at least 4 times, which lasts for about 2 days.
3) And (3) testing: the setting of light color and illumination intensity is the same as the adaptation process.
Before testing, red and yellow photographic paper is randomly placed for 3 times of later training to prevent the poultry from forgetting, and then the poultry enters the testing.
The red photographic paper is fixedly selected and unchanged, the yellow photographic paper is replaced by a plurality of photographic papers with G components in the RGB color space from high to low one by one, namely, the yellow photographic paper with the original (255, 0) RGB colors, namely, the six RGB colors of (255,219,0), (255,182,0), (255,146,0), (255,109,0), (255,73,0) and (255,36,0), so that the color of the paired photographic paper is gradually close to red. The six colors are designated test 1 to test 6 in this order. If the test color 1 has an RGB value of (255,219,0), the test color 6 has an RGB value of (255,36, 0).
After the photographic paper is replaced each time, performing the same treatment as the post-training in the step 2.2), wherein the testing times are 10 times, the paired photographic paper with the color difference being greater than the first color difference is used for training 3 times before each testing, and the result of whether the poultry in each testing identifies the red photographic paper is accurate is recorded, so that the accuracy of identifying the red photographic paper by the poultry under specific ambient light is obtained, and the influence of the ambient light on identifying the red object by the poultry is judged.
Thus, 6 types of photographic paper were paired with red and yellow photographic paper, respectively, and two pairs of photographic paper were tested each day for about 3 days. Before each test, 3 post-training times of paired photographic paper with the chromatic aberration being greater than one are required to prevent forgetting. If the test color 5 photographic paper is selected for testing, the test color 4 photographic paper and the red photographic paper are matched for 3 times of later training before testing.
The poultry is fed with sufficient water throughout the feeding process. However, in order to prevent the failure of the food reward method, the training and testing process requires starvation of the birds. The feeding time of the poultry is only 3, firstly, the experiment is carried out, secondly, the poultry finishes the experiment till the experiment is finished in the same day, and thirdly, the poultry is cleaned within half an hour after the experiment is finished in the same day. If the poultry have the experiment in the same day, no feed is supplied from the time the poultry are cleaned in the previous day to the time the experiment begins in the same day, so that the poultry are kept in a hungry state.
After the test of each light intensity under a certain light color or each light color under a certain light intensity is completed, the light color or the light intensity can be replaced to carry out a new round of detection, but the process only comprises the later training and the test of the same steps. Because the detected objects are the same batch of poultry, the training time of the middle and later period of the new detection is only 1 day generally. Tests were also performed for a period of 3 days after training was completed.
Generally, 2-3 groups of light color or illumination intensity are set, so that the experimental time of each day is controlled within half a day, and the interference of the day and night rhythm on the experiment is reduced. The time required for each stage of the detection process is only an estimate, and may vary slightly as the number of groups increases or decreases.
The utility model discloses the example.
In the example, 21 yellow-feathered broilers with similar body types and ages of 8 weeks are selected as research objects, the light colors adopted in the example are 6500K and 2700K, and the broilers are randomly divided into 3 groups according to the low (2lux), medium (20lux) and high (50lux) illumination intensity, and each group comprises 7 chickens. Two broilers with poor performance in training are removed from each group of the illumination intensity, so that 5 broilers in each group are tested. The entire experimental procedure lasted 12 days, including 5 days of acclimation, 4 days of training and 3 days of testing.
Therefore, the utility model discloses a detection device tests, can be used to detect the influence of environment light to the red object of poultry discernment, breeds through the luminous environment for the poultry and prevents and control and peck the tree and provide the laboratory tool.
