Problems solved by technology

Different breeders have different judgment results, and the judgment results of the same breeder in different environments are also significantly different. Accurate predictions cannot be achieved, and the best breeding time is often missed, which affects the quality of conception and birth.

Embodiment 1

[0060] see figure 1 , the present embodiment provides a method for analyzing estrus in sows, the method comprising steps A to D:

[0061] Step A: Determine whether the number of standing times and standing time of the sow at night exceed the estrus threshold, and if so, determine that the sow is in estrus. The important sign of sows entering estrus is that sows stand up / ly down frequently and the frequency of activities increases rapidly. The estrus threshold is the system preset value, which can be set in advance according to the actual breeding environment, sow breed and status and other parameters.

[0062] During the night time, organisms are mostly in a resting state, and the influence of external factors drops to an ideal range. For example, the activities of the breeders (feeding, cleaning, etc.) have basically stopped, and the environmental noise has dropped to an ideal range. Therefore, the frequent standing of sows at night is mainly caused by estrus, and the exte...

Embodiment 2

[0097] see Figure 8 , the present embodiment provides a sow estrus analysis device 100, the device includes:

[0098] The estrus judgment module 110 is used to judge whether the number of standing times and the standing time of the sow at night exceed the estrus threshold, and if so, determine that the sow is an estrus sow;

[0099] The obtaining and filtering module 120 is used to obtain the standing times and standing time of the sow in estrus during the estrus period, and remove the disturbance data caused by collective standing of sows near the sow in estrus, so as to obtain effective estrus data;

[0100] A linear regression module 130, configured to perform segmented linear regression on the effective estrus data to obtain a estrus trend line;

[0101] The prediction calculation module 140 is used for determining the estrus end time and the best insemination time of the estrus sow according to the estrus trend line.

[0102] see Figure 9 , Exemplarily, the estrous j...

Embodiment 3

[0127] see Figure 15 This embodiment provides a terminal 200, the terminal 200 includes a memory 210 and a processor 220, the memory 210 is used to store a computer program, and the processor 220 executes the computer program so that the terminal 200 implements the above-mentioned sow estrus analysis method.

[0128] Wherein, the terminal 200 includes terminal devices (such as computers, servers, etc.) that do not have mobile communication capabilities, and also includes mobile terminals (such as smart phones, tablet computers, vehicle-mounted computers, smart wearable devices, etc.).

[0129] The memory 210 may include an area for storing programs and an area for storing data. Wherein, the storage program area can store the operating system, at least one application program required by the function (such as sound playback function, image playback function, etc.); the storage data area can store data created according to the use of the terminal 200 (such as audio data, backu...

Abstract

The invention relates to a sow estrus analysis method and device, a terminal and a computer readable storage medium. The method includes: judging whether the standing times and standing time of a sowat night exceed an estrus threshold or not, and if so, judging that the sow is in estrus; acquiring the standing times and standing time of the sow in estrus, and removing disturbance data caused by the collective standing of sow around the sow in estrus to obtain effective estrus data; performing piecewise linear regression on the effective estrus data to obtain an estrus trend line; determiningthe estrus ending time and optimal insemination time of the sow according to the estrus trend line. The sow estrus analysis method and device, the terminal and the computer readable storage medium have the advantages that the estrus state of the sow is precisely judged through scientific quantitative calculation, the estrus ending time and optimal insemination time of the sow in estrus is precisely speculated, and mating precision and quality are increased effectively.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and specifically relates to a sow estrus analysis method, device, terminal and computer-readable storage medium. Background technique [0002] Pig farming is an important industry in agriculture and plays an important role in ensuring the safe supply of meat. my country's pig breeding industry has a long history, which can be traced back thousands of years ago. At present, my country's pig industry is transforming from traditional pig industry to modern pig industry. Significant changes are taking place in the breeding mode, regional layout, production mode and production capacity. [0003] Nevertheless, the current pig industry still lacks scientific breeding guidance, and experience breeding occupies an important position. Experience breeding relies on the subjective judgment of the breeder, which is prone to error fluctuations and affects the judgment results, and lacks universality to ...
