A breathanalyser type setup characterised by an area whereupon food is used as reinforcer whilst taking a gaseous sample for analysis

摘要

An apparatus and a method are provided for automatically collecting a sample of cow's breath. The apparatus comprises an inlet (5) in an animal stall, e.g. a cattle stall, which is connected to collecting or analysing apparatus. A sensor (16) is provided for sensing a flow of breath into the apparatus. A food incentive is automatically dispensed when the sensor is activated, thereby inducing the animal to provide a breath sample. A method for training an animal to use the apparatus is also described, comprising the distribution of food incentives in the locality of the apparatus at random time intervals, together with the gradual increasing of the length and/or strength of exhalation necessary to result in the dispensing of food incentive.
