Detection device and system for sow estrus

Abstract

The invention discloses a detection device and a system for detecting a sow estrus. The technical problem to be solved is to improve the accuracy rate of the sow estrus and the quantity of farrowing. The invention adopts the following technical scheme that: a central processing unit is aranged on the detection device for the sow estrus, wherein the central processing unit is connected with a distance measuring sensor, an output unit and an input unit. A data analyzing module is aranged on the system for detecting the sow estrus, wherein the data analyzing module is connected with a parameter input module, a sensor data input module and a result output module. Compared with the prior art, the detection device and system mounted on a sow hog lot are adopted, so that a distance between a sow and the detecting device can be detected in real time, a change characteristic of the distance is analyzed in real time, and whether the sow is in an estrus is predicted according to the change characteristic, and the detection device and system have the characteristics of simple method, convenience, easiness in operation, saving in manual labor intensity and improvement in accuracy rate.

Description

technical field [0001] The invention relates to a livestock breeding device, in particular to a sow estrus detection device and system. Background technique [0002] At present, most pig farms in my country have adopted the feeding mode of positioning pens for the feeding of sows. There are three methods commonly used for sow estrus detection. External manifestations such as swollen and shrunken vulva, staring, raised tail, erect ears, urination, back stiffness, daze, etc.; acceptance of boar climbing, hand pressing on the back, sitting still on the back, climbing fences and jumping circles, etc. This method will waste a lot of manpower and material resources, and at the same time judge the staff to be strict, otherwise it will directly affect the litter size. 2. The boar test method, even if a qualified boar passes the sow pen once a day in the morning and evening, if the sow is in heat, it will immediately walk to the pig pen. 3. Odor and sound method, that is, use the sm...

AI Technical Summary

Problems solved by technology

The first two methods require a lot of manpower. Although the last method saves manpower, it cannot know in time whether it is the beginning of estrus or the end of estrus. It is difficult to know the best time for breeding, so the accuracy of estimation is also poor.
