Description

Technical Field

[0001] This invention relates to the field of cattle heat stress monitoring technology, and in particular to a cattle neck collar device and a cattle heat stress monitoring system. Background Technology

[0002] Heat stress is a major challenge in dairy farming systems. Cows under heat stress suffer welfare impairments, leading to production losses. With the increasing frequency and severity of heat stress events in recent years, reducing heat stress in cattle has become particularly important, and accurate monitoring of the heat stress status of cattle provides crucial information for the timely detection of heat-stressed cattle.

[0003] Body temperature is an important physiological indicator. Under normal circumstances, a cow's body temperature remains relatively constant, exhibiting certain regular changes with physiological activities, such as estrus, ovulation, pregnancy, and heat stress. Simple, accurate, and effective monitoring of bovine body temperature changes not only helps in accurately monitoring heat stress in cattle but also facilitates proactive and effective disease monitoring, prevention, and control. However, most cattle farms still use mercury thermometers for rectal temperature measurement. This method is inefficient, cannot accurately obtain real-time temperature data for each cow, requires significant manpower, and is time-consuming and labor-intensive, far from meeting the management requirements of modern large-scale farms.

[0004] Currently, modeling and farm experiments have been used to assess the effects of heat stress on livestock, and mitigation solutions, including optimal shed structure, ventilation, feeding regimes, farm management, and genetic selection, have been explored. However, the heat tolerance and coping abilities of dairy cows can vary significantly under different farm conditions. To date, the results of different mathematical models have provided various heat stress thresholds for farm use; however, in practice, determining whether cattle are under heat stress still faces some limitations.

[0005] First, existing heat stress monitoring devices often lack integration and real-time capabilities, failing to reflect the individual heat stress status of dairy cows in a timely manner and unable to provide timely heat stress warnings. This results in the inability to quickly take effective mitigation measures, affecting the health and production performance of dairy cows. Second, most collars currently on the market only collect information on the activity level, feed intake, and rumination of dairy cows, without involving the collection of physiological indicators. Third, existing monitoring devices are structurally complex, not only cumbersome to wear but also easily affecting the cows' activity and resulting in poor comfort. In addition, some existing devices are not adaptable to cows of different sizes or have complicated size adjustment operations.

[0006] There are still no effective solutions to the problems in the relevant technologies, such as the inability to accurately detect heat-stressed cattle, the complexity of wearing and operating monitoring equipment, the inability to adaptively adjust the size according to the cattle's body size, and the poor comfort of the monitoring equipment. Summary of the Invention

[0178] When the THI is 72 or lower, it indicates that the animal is not under heat stress; when the THI is between 73 and 77, it indicates that the cattle are under mild heat stress; when the THI is between 78 and 89, it indicates that the cattle are under moderate heat stress; when the THI is 90 or higher, it indicates that the cattle are under severe heat stress.

[0179] Processing of cattle temperature, heart rate, and respiration data:

[0180] The normal body temperature of cattle is 38℃~39℃, and the heart rate (pulse) is 60~70 beats / minute. The normal respiratory rate of adult cows at rest is 18~28 breaths / minute, and that of calves is 20~40 breaths / minute.

The angle adjustment element 301 adjusts the angle of the first neck collar element 101 and the second neck collar element 201 according to the size of the cow's neck. During use, it can also be adjusted according to the cow's posture. Then, the first base element 401 and the second base element 408 are held, and the second sliding element 409 is inserted into the first sliding element 402 and abuts against the baffle element 407. The baffle element 407 is pushed to slide relative to the first sliding element 402, the second elastic element 406 deforms, the first locking element 404 enters the groove element 403, and the first elastic element 405 deforms. When the second locking element 410 is located in the groove element 403, the first elastic element 405 returns to its original shape, the first locking element 404 enters the second locking element 410, and the relative positions of the first sliding element 402 and the second sliding element 409 are locked.

[0188] Temperature monitoring element 601 monitors ambient temperature and humidity in real time, and also monitors the temperature information of cattle in real time. Heart rate monitoring element 602 monitors the heart rate information of cattle in real time, and respiratory monitoring element 603 monitors the number of times cattle breathe per unit time in real time and transmits the data to control element 701. Control element 701 determines whether cattle are in a state of heat stress according to preset standards.

[0189] The technical effects of this invention are as follows:

[0190] The angle adjustment unit adaptively adjusts the angles of the first and second neck collar units in real time according to the cattle's physique and posture, ensuring the cattle's comfort and solving the problems of inability to adaptively adjust size according to cattle's physique and poor comfort of monitoring equipment. The locking unit allows for easy connection or separation of the first and second neck collar units, simplifying operation and solving the problem of complex wearing and operation of monitoring equipment. The environmental monitoring unit monitors the temperature and humidity of the environment in which the cattle are located in real time, and the vital signs monitoring unit monitors the cattle's body surface temperature, heart rate, and respiratory rate in real time. The control unit obtains information from the environmental monitoring unit and the vital signs monitoring unit and accurately judges the cattle's heat stress status. It can monitor the stress status of cattle in real time, making it easier for farmers to cool down cattle that have experienced heat stress in a timely manner, solving the problem of not being able to accurately detect cattle with heat stress.
