First claim

What is claimed is:

1. A lighting experimental system for reducing an ability of poultry to recognize red objects, comprising:
a wooden testing box,
black polyvinyl chloride (PVC) backdrops,
a square adjustable light-emitting diode (LED) light source,
color photographic papers,
pressure sensors,
a feed box,
an electric push rod, and
a feces receiving cloth, wherein
the wooden testing box is a square wooden box provided with an opening at a top thereof,
the square adjustable LED light source is disposed directly above the opening of the wooden testing box,
a first black PVC backdrop is fixedly laid on a surface of each inner wall of four sides of the wooden testing box, and the gray feces receiving cloth is laid at a bottom of the wooden testing box;
a horizontal trough is disposed at a bottom of an inner wall on one side of the wooden testing box,
the feed box is disposed in the horizontal trough, the feed box is connected to the electric push rod, the electric push rod pushes the feed box to move horizontally to drive the feed box into the wooden testing box or out of the wooden testing box through the horizontal trough;
two color photographic papers are fixed on the inner wall, directly above the horizontal trough of the wooden testing box,
the pressure sensors are disposed between the two color photographic papers and the inner wall of the wooden testing box, and the two color photographic papers are pure-color photographic papers of different colors; and
a second black PVC backdrop for blocking is disposed outside the inner wall, on which the two color photographic papers are fixed, of the wooden testing box.

2. The lighting experimental system for reducing the ability of the poultry to recognize the red objects according to claim 1 , wherein the second black PVC backdrop is connected to and mounted on a lifting mechanism, and the second black PVC backdrop is driven by the lifting mechanism to move down to block and cover the two color photographic papers or move up not to block and cover the two color photographic papers.

3. The lighting experimental system for reducing the ability of the poultry to recognize the red objects according to claim 1 , wherein the two color photographic papers are pasted horizontally and symmetrically on the inner wall of the wooden testing box and are located at two upper sides of the feed box.

4. The lighting experimental system for reducing the ability of the poultry to recognize red objects according to claim 1 , wherein the detection system is used for lighting during indoor broiler breeding.

5. The lighting experimental system for reducing the ability of the poultry to recognize the red objects according to claim 1 , wherein poultry feed is placed in the feed box.

6. The lighting experimental system for reducing the ability of the poultry to recognize the red objects according to claim 1 , wherein feed is pasted in a center of each of the color photographic papers when training.

7. A lighting experimental method for reducing an ability of poultry to recognize red objects by using the detection system of claim 1 , comprising a detection process, wherein the detection process comprises adaptation, training, and testing in sequence:
1) The adaptation comprises:
placing a red photographic paper with an RGB color (255, 0, 0) and a yellow photographic paper with an RGB color (255, 255, 0), performing lighting by using the square adjustable LED light source to provide an ambient light, and putting the poultry into the wooden testing box in sequence for a period of time to enable the poultry to adapt to an internal closed environment;
2) The training comprises:
2.1) early training:
on a first day, pasting a grain of feed on a surface of each of the two color photographic papers by using an adhesive tape, and putting little feed into the feed box, and training, by a food reward method, the poultry to recognize the red photographic paper; and when the poultry peck the red photographic paper, pushing, by the electric push rod, the feed box into the wooden testing box through the horizontal trough to allow the poultry to peck the little feed for 4 s, and then pulling, by the electric push rod, the feed box out of the wooden testing box to prevent the poultry from pecking the handful of little feed; or when the poultry peck the yellow photographic paper, disabling the electric push rod, and giving no feed reward; and
removing the feed on the surface of each of the two color photographic papers after the poultry have correctly recognized the red photographic paper for three times, and then performing later training on the poultry; and
2.2) later training:
blocking the two color photographic papers by using one second black PVC backdrop, quickly removing the second black PVC backdrop after maintaining or reversing positions of the two color photographic papers, observing responses of the poultry to the two color photographic papers, and determining whether the poultry recognize and peck the red photographic paper; and repeating the training until the poultry recognize the red photographic paper for ten consecutive times;
3) Testing:
keeping the red photographic paper unchanged, and successively replacing the original yellow photographic paper with the RGB color (255, 255, 0) by a plurality of photographic papers whose G components in a RGB color space are sorted in descending order, to make colors of paired photographic papers gradually approximate to a red color; and
after each replacement, performing the later training in step 2.2), repeating the testing for twelve times, and recording results of last ten times indicating whether the poultry accurately recognize the red photographic paper in the testing.

8. The lighting experimental method for reducing the ability of the poultry to recognize the red objects according to claim 7 , wherein in the testing in step 3), RGB colors of the plurality of photographic papers whose G components in the RGB color space are sorted in descending order are (255, 219, 0), (255, 182, 0), (255, 146, 0), (255, 109, 0), (255, 73, 0), and (255, 36, 0), respectively.

9. The lighting experimental method for reducing the ability of the poultry to recognize the red objects according to claim 7 , wherein before the training and the testing, the poultry are kept hungry.

10. The lighting experimental method for reducing the ability of the poultry to recognize the red objects according to claim 7 , wherein the poultry comprise chickens.
