Effect of animal activity and air temperature on heat production, heart rate, and oxygen pulse in lactating Holstein cows
ABSTRACT: A linear relationship between heart rate (HR) and oxygen consumption (VO2) has been reported in homeothermic animals, indicating that is possible to estimate heat production through HR measurements. This relationship may depend on the animal activity and environmental conditions. The main...
