Abstract

To solve such problems that, when a person sees and determines an estrous behavior of a livestock animal, overlooking may occur because it is difficult for the person to see the animal all the time, that as a situation the estrus occurs in a cycle of about 23 days, it is necessary for the livestock animal to be fertilized in about 24 hours during the estrus, that if the estrus is overlooked, the livestock animal cannot be fertilized for about 23 days until the next estrus, and that leads to economical losses of the feed cost being increased and the number of calves that can be produced in a lifetime being reduced.SOLUTION: Since cows show behaviors (mounting behaviors) like mounting another cow or being mounted by the other cow as behaviors that livestock animals like cows show estrus, a livestock animal estrus detection system performs image analysis with an artificial intelligence or the like on mounting behaviors from image data acquired by installing cameras in a livestock barn, detects the mounting cows and simultaneously detects the entire cows of the mounting cows and the mounted cows in order to determine estrus or not, increases detection accuracy by determining as estrus when both of the cows are detected at a high probability within a certain time, and notifies a livestock farmer of the information.SELECTED DRAWING: Figure 1

Description

Since livestock animals such as cows exhibit estrous behaviors such as riding on or being ridden by other cows (climbing behavior), the present invention uses a camera installed in a livestock barn to acquire image data. Image analysis of riding behavior etc. from the cow is performed using artificial intelligence etc., and in order to determine whether it is in estrus or not, the riding cow is detected at the same time as the riding cow and the whole cow being ridden, and both are detected for a certain period of time. Livestock animal livestock estrus detection system equipped with a computer device that raises the detection accuracy by discriminating as estrus when it is detected with a high probability within the livestock farm and notifies the livestock farmer.

There is a technique for identifying image data with specific features by image analysis using artificial intelligence or the like.
There is also a technique for measuring the number of steps and the amount of movement by attaching equipment to livestock animals.

When the estrus behavior of livestock animals is visually judged by humans, it may be overlooked because it is difficult to constantly observe. Estrus occurs in a cycle of about 23 days, and it is necessary to fertilize during about 24 hours of estrus. This leads to economic losses such as a decrease in feed costs and a decrease in the number of calves that can be born in a lifetime.
In addition, attaching equipment to livestock animals requires labor and stress for humans, and poses a risk of physical burden, stress, and infectious diseases for cattle.
The object of the present invention is to detect estrus by using a camera instead of the human eye to capture the image of the estrus of a cow and using a computer device such as artificial intelligence instead of the human brain to detect the estrus and save human effort. To provide a livestock animal estrus detection system for improving productivity by reducing stress, reducing physical burden and stress of livestock animals, and reducing risks such as infectious diseases.

A representative configuration for achieving the above object is as follows. That is, the livestock animal livestock estrus detection system according to the present invention includes:
(1) Image data of livestock animals whose estrus is to be found is photographed with a camera.
(2) Equipped with a computer device that analyzes images by means of artificial intelligence or the like and detects behaviors that indicate estrus from image data, such as behaviors of riding on or being ridden by another cow (climbing behavior).
(3) At the same time that the riding cow is detected, the riding cow and the whole riding cow are detected, and if both are detected with a high probability within a certain period of time, it is determined as estrus, thereby improving the detection accuracy. Equipped with a computer device for raising and notifying livestock farmers.

In the present invention, image analysis is performed on the image data of livestock animals whose estrus is to be found, captured by a camera, estrus is detected, and notification is made to livestock farmers, thereby reducing human labor and stress, thereby increasing productivity. It can reduce the burden and stress on the body of livestock animals and reduce the risk of infectious diseases.

1 is a configuration diagram of an embodiment of a livestock animal livestock estrus detection system according to the present invention; FIG. 1 is a flow chart showing a control procedure of an embodiment of a livestock animal livestock estrus detection system according to the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of examples.

1 and 2 show an embodiment of a livestock animal estrus detection system according to the present invention.
In FIG. 1, a cow whose estrus is to be found is photographed with a camera.
In FIG. 1, a camera detects the cow's riding behavior and the like from the image data shown in FIG. 2 by means of artificial intelligence.
In Fig. 2, when a riding cow is detected, the riding cow and the whole riding cow are detected at the same time, and if both are detected with high probability within a certain period of time, the detection accuracy is improved by discriminating as estrus. Raise it and notify the livestock farmer as estrus. If both are not detected with a high probability, the process is terminated as a misleading state or an erroneous detection.

Claims (1)

Livestock animals such as cows exhibit estrous behaviors, such as riding and being ridden by other cows (climbing behavior). Image analysis is performed on conditions such as galloping behavior using artificial intelligence, etc., and in order to determine whether the cow is in estrus or not, the riding cow is detected at the same time as the riding cow and the whole cow being ridden, and both are detected for a certain period of time. A livestock animal livestock estrus detection system characterized by increasing the detection accuracy by discriminating as estrus when it is detected with a high probability within the livestock farm and notifying the livestock farmer.
