Description

A cow cooling system and a cow cooling method in an active area

technical field

The invention relates to a pasture cooling system, in particular to a cow cooling system and a cow cooling method in an active area.

Background technique

In summer, the weather is hot and humid, and the heat stress of dairy cows is very serious. Heat stress is very harmful to dairy cows, especially the milk production, milk indicators, reproductive performance and health of dairy cows. . In order to reduce the impact of heat stress on dairy cows, a cooling device needs to be installed. In the prior art, the cooling device in the pasture is generally a fan or a fan and a spray device are installed at the same time, and the cows are cooled by spraying and blowing. Some cooling devices are installed in specific areas, such as feeding areas, so that the cooling can only be performed when the cows are in a specific link, or some are installed on the cowshed to cool all cows in the entire cowshed. The existing cooling method is to cool the cows indiscriminately, but the body temperature of the individual cows is different. When the cows that do not need to be cooled are forcibly cooled, due to the change of body temperature and the increase of the surrounding humidity, it is more likely to generate heat. stress. For cows who feel that the temperature is high and need to be cooled, they cannot be cooled at any time, resulting in heat stress in the cows not being cooled in time. The existing cooling methods for dairy cows cannot effectively solve the heat stress phenomenon of all dairy cows, which reduces the milk production of dairy cows. In addition, the existing cooling system is not intelligent enough to accurately count the response of each individual cow to temperature and the influence of the number of sprays and the cooling range on the heat stress of each individual cow.
