Description

Technical Field

[0001] The invention relates to the technical field of cattle heat stress monitoring, and in particular to a cattle collar device and a cattle heat stress monitoring system. Background Art

[0002] Heat stress is a major challenge for dairy farming systems. Cows in heat stress will suffer from impaired welfare, leading to production losses. With the increase in the frequency and magnitude of heat stress events in recent years, it has become particularly important to reduce heat stress in cattle. Accurate monitoring of heat stress in cattle provides an important basis for timely detection of heat stressed cattle.

[0003] Body temperature is an important physiological indicator of the body. Under normal circumstances, the body temperature of cattle will change regularly within a relatively constant range with changes in physiological activities, such as estrus, ovulation, pregnancy and heat stress. Simple, accurate and effective monitoring of cattle body temperature changes not only helps to accurately monitor heat stress in cattle, but also can actively and effectively monitor, prevent and control diseases. However, most cattle farms still use mercury thermometers for rectal temperature measurement. This method has low temperature measurement efficiency and cannot accurately and real-time obtain the body temperature data of each cow. It also requires a lot of manpower, is time-consuming and labor-intensive, and is far from meeting the management requirements of modern large-scale ranches.

[0004] Modelling and on-farm experiments have been used to assess the impact of heat stress on livestock, and mitigation solutions including optimal shed construction, ventilation, feeding regimes, farm management and genetic selection have all been explored. However, the heat tolerance and ability of dairy cows to cope with heat can vary greatly under different farm conditions. So far, the results of different mathematical models have provided various heat stress thresholds for on-farm use, however, in practice, how to determine when cattle are under heat stress still faces some limitations.

[0005] First, some existing heat stress monitoring equipment often lacks integration and real-time performance, and cannot reflect the individual heat stress status of dairy cows in a timely manner, and cannot provide timely heat stress warnings, resulting in the inability to quickly take effective mitigation measures, affecting the health and production performance of dairy cows; secondly, most collars on the market currently only collect information on the activity, feeding and rumination of dairy cows, and do not involve the collection of physiological indicators of dairy cows; thirdly, the structure of existing monitoring devices is relatively complex, which is not only troublesome to wear, but also easy to affect the activity of cattle and has poor comfort; in addition, some existing devices cannot adapt to the wearing of cattle of different physiques or the size adjustment operation is complicated.

[0006] There is no effective solution to the problems in related technologies, such as the inability to accurately detect heat stressed cattle, the complexity of wearing and operating the monitoring equipment, the inability to adaptively adjust the size according to the cattle's physique, and the poor comfort of the monitoring equipment. Summary of the invention
