ABSTRACT:
An artificial vagina for collecting semen used in animal breeding includes a heatable tubular jacket with a tubular interior component made of resilient material, surrounded by the jacket and fastened to it in a fluid-tight manner to define an annular chamber between the jacket and interior component. Heat is applied to the jacket, some of which is transferred to the interior component. Air is introduced into the annular chamber to establish an air layer, and the radial thickness of the air layer is steplessly adjusted (e.g. in a stimulation ring using different air connections) so that the rate of heat transfer between the jacket and interior component is controlled, and to facilitate use as an artificial vagina.
