title: Right Müllerian duct in the domestic fowl during postnatal ontogenesis.
abstract: In this study the postembryonal changes of the right Müllerian duct are investigated. This structure was found in all female broilers of the hybrid combination Ross 1 as well as in hens of the female line of parent stock for the production of this hybrid. A thready structure of the length of several millimeters observed in one-day-old females develops in chicks into a long, thin-walled ampula filled up with clear liquid. In mature hens this rudiment is markedly long and its shape is rather different. In some cases the Müllerian duct was divided into several parts which might be compared with individual parts of the left oviduct.
