HERD CONTROL AND/OR MONITORING PROCEDURES

摘要

A method of herd management which includes providing each member of the herd with a device (eg; an intra vaginal device) capable of identifying the membe r, of sensing at least one physiological condition of the member of the herd an d communicating with other such devices and/or a base station. With such communication the proximity of devices each other allows groupings to be determined such as a grouping indicative of behavioural oestrus. With such devices it is possible by monitoring groupings of the animal to determine those in oestrus and to have the device administer appropriate active ingredients to some of the animals of the herd.
