Collecting rooster sperm

The researchers are testing whether females grow bored mating with the same male. Consequently, the avian male reproductive tract is entirely inside the body, as shown in Figure 1. One remarkable aspect of the male avian reproductive system is that the sperm remain viable at body temperature.

I have all my chickens in a warm room for the winter, but come spring I plan to separate them by breeds to raise pure breed chickens. Total sperm output was therefore considerably lower in Griffon vultures used in the current study. As shown in the image to the right, an AV is composed of a tube with an outer rubber lining that will hold water, into which is placed an inner liner that is lubricated just prior to use.
