An Active Drying Sensor to Drive Dairy Cow Sprinkling Cooling Systems

نویسندگان

چکیده

The use of sprinkling with ventilation to cool dairy cows is considered an appropriate practice reduce the negative effects heat stress. However, due climate change, water will increasingly become a limited resource, so we need make more and efficient. For this purpose, active drying sensor has been developed in order time cooling system. reproduces thermal response cow, considering both sensible latent exchange, located feeding alley, about two meters above floor. This allows fabric (simulating fur) be wetted by sprinkler, blown fan. content during monitored measuring its electrical conductivity, allowing estimation fur becomes dry. Another specifically designed instruments are presented, first estimate fur’s after spraying, second detect became Sensor output, interpreted through simplified model, gave predicted error ranging between −11.4% +14.8% (R2 = 0.789). In commercial barn where experiments were conducted, allowed estimated reduction consumption 57%, respect fixed timing normally used. As perspective, could used assess cows’ stress level.
