Embodiments of the present invention are directed to a device and method for identifying estrus in production animals by detecting one or more standing mounts with a single device.

The invention relates to a sow oestrus detection method and device. The sow oestrus detection method comprises the steps that boar pheromones are released to sows; playing a boar courtship sound to the sows; interacting with the sows by using the mouths and noses of bionic boars; collecting image data of the sows; processing the image data by using a model based on a deep learning algorithm to obtain sow oestrus detection data; and the model based on the deep learning algorithm comprises a Mask R-CNN model, the sow oestrus detection data comprise appearance characteristic data during sow oestrus and interaction data with the mouths and noses of the bionic boars. Good bionic estrus checking and testing effects are achieved by releasing boar pheromones and playing boar courtship sound and matching with the mouths and the noses of the bionic boars, and rapid and intelligent estrus detection is achieved by collecting images and intelligently processing the images.

The invention relates to the technical field of electronic detection devices, in particular to a cow oestrus detection necklace which comprises a band-shaped necklace body and an oestrus detection device.The oestrus detection device is arranged on the band-shaped necklace body and comprises an acquirer, a processor and an oestrus warning device, and the acquirer, the processor and the oestrus warning device are sequentially connected with one another; the acquirer is used for acquiring cow activity information and transmitting the cow activity information to the processor via a data wire; the processor is used for judging whether cows are in normal states or oestrus states and transmitting judgment results to the oestrus warning device via a data wire; the oestrus warning device is used for displaying current states of the cows.The cow oestrus detection necklace has the advantages that the cow oestrus detection necklace is simple in structure and is convenient and practical, and the labor intensity can be relieved for observation staffs; activity of the cows is monitored in real time, so that the cow oestrus period disclosure rate can be increased; the optimal mating time can be determined according to disclosed oestrus time, accordingly, the milk yield of the cows can be increased, and the cow oestrus detection necklace is favorable for the economical efficiency.

The present invention provides a cattle estrus early warning method, which collects cattle body activity and cattle body temperature, and when the rise of the cattle body activity at any collection time point is higher than the average historical cattle body activity at the same collection time point in the previous 7 days 2.5 times the amount of bovine body activity, and the duration of the increase in the amount of bovine physical activity is not less than 1 hour, and there is at least one peak, which is an early warning of estrus; further, when the body temperature at any collection time point is higher than that at the same collection time point in the previous 7 days The average body temperature is 0.3°C higher, and the duration is not less than 4.5 hours, which can further improve the accuracy of early warning of cattle estrus. Combining the two detection methods for estrus detection can solve these shortcomings. Therefore, the cattle estrus early warning method of the present invention can effectively improve the detection rate and accuracy of cattle estrus, and has important application value.

The invention discloses a sow estrus detection method and system. The method includes the following steps that an intelligent ear tag collects the body temperature and exercise data of a sow in real time and the data is uploaded to a management terminal through an intelligent gateway; when the sow takes foods from a food trough, the intelligent gateway at the food trough uploads the received datasent by the intelligent ear tag to the management terminal, and at the same time, the intelligent gateway records the residence time of the intelligent ear tag in the food trough area and uploads it to the management terminal and the management terminal analyzes the sow's food intake and eating frequency according to the residence time; the management terminal analyzes the received data, and whenthe corresponding body temperature, amount of exercise, food intake and feeding frequency of the sow meet specific indexes, the management terminal judges that the sow is in the estrus period and informs staff. The method can determine whether the sow is in the estrus period by analyzing the sow's body temperature, amount of exercise, food intake and feeding frequency so that the sow in the estrusperiod can be found in time and the breeding rate can be improved.

The invention provides a method for improving a sow pregnancy rate. The method comprises the steps of pre-breeding preparing, seminal fluid collecting and storing before breeding is carried out and estrus detection and breeding of a breeding sow. According to the method, the pregnancy rate of a sow can be increased more than 95%, the empty pregnancy rate for sow breeding is greatly lowered, the service life period of the sow is prolonged, the morbidity of a sow breeding system is greatly lowered, and the piglet birth rate is stable.

The invention relates to a method for conducting early warning of cow rutting by detecting the temperature of the vagina of a cow. The method comprises the steps of continuously detecting the temperature of the vagina of the cow, recording the temperature change, and conducting early warning of cow rutting when the temperature of the random time point is raised to be 0.3 DEG C higher than the temperature average value of the same time point of the first 7 days. Through multiple times of exploration and verification, the temperature change rule of the vagina when the cow ruts is revealed, on this basis, a temperature change threshold value of cow rutting is judged, a cow rutting identification technology is originally developed, and automated monitoring of cow rutting is achieved. Despite partial false positive situations, no false negative situations occur, which shows that through the threshold value, all rutting cows can be identified, and the economic loss of a cattle farm cannot becaused. It is shown that the temperature threshold value has an ideal detecting result in detecting cow rutting, and has high application value.

An estrus detection device is composed of a resin case (2) and a belt (20) to be attached to a livestock animal. The case (2) contains a triaxial acceleration sensor (40) as an activity sensor for detecting the motion of the animal; a signal processing unit (41) for converting the output of the triaxial acceleration sensor (40) to the amount of activity; a temporary storage unit (42) for storing the output of the signal processing unit (41) as the present amount of activity; a storage unit (43) for storing, as the past amount of activity for a past predetermined time period, the amount of activity stored so far in the temporary storage unit (42); an estrus determination unit (44) for determining whether the animal is in estrus or not based on the past amount of activity and the present amount of activity; and a display part (30) for showing that the animal in in estrus when the estrus determination unit (44) has determined that the animal in in estrus.
