Abstract

The health and welfare of feedlot animals are observed with a monitoring system that is simple to implement and easily expandable depending on the feedlot operator'"'"'s need. The monitoring system uses a sleeve that is removably attached to an appendage of the animal, such as its tail. The sleeve contains a biosensor for sensing the animal'"'"'s physiological parameters and a microprocessor for processing these sensed parameters. When the animal'"'"'s monitored physiological parameter is out of a predetermined "healthy" range, the microprocessor activates an alarm to alert the feedlot operator of a potential health problem for that particular animal. The sleeve can optionally contain a transmitter so that the sensed physiological parameters can be transmitted to a base station. Additionally, the monitoring system can be expanded to include animal tracking capability so that the animal'"'"'s feeding and watering habits can also be monitored at the base station. A GPS-system or a tag-based system may be used to track the animals.
