THE EJECTION OF A FROTHY FLUID FROM THE CLOACAL REGION OF ROOSTER DURING MANUAL SEMEN COLLECTION

Abstract

The ejection of a frothy fluid from the rooster cloaca was observed during the collection of semen by the conventional manual method. The production of the frothy fluid was confirmed to be related to the tumescent portion of the dorsal cloaca, i.e. glandula proctodealis dorsalis (GPD), and the GPD was considered to be homologous to the triangular fold (TF) in the corresponding region of the male turkey cloaca. Electrical cauterization of the GPD led to a complete cessation of the ejection of a frothy fluid. Key words: Frothy fluid, cloaca, rooster
