AVIAN REPRODUCTIVE TRACT

A labeled photograph of the reproductive tract of a laying hen pdf

A video clip of Dr. Bacon discussing egg formation and the reproductive tract of a laying hen To the left of the reproductive tract of the laying hen (stimulated) is the reproductive tract and part of the large intestine of a hen that has not been exposed to long day lengths (non-stimulated). Long day lengths (vs long nights) signal birds that it is spring and it is safe to start laying eggs, so the ovary and oviduct change from the size on the left to the size on the right. The non-stimulated ovary is on the lower left with the oviduct between the ovary and the vent. The large intestine also attaches to the vent and is to the upper right of the vent.
