This method of artificial insemination is used in systems where turkeys are not housed in pens. The catcher and inseminator do not move between pens, instead the hens are guided to a central area where the catcher and inseminator are positioned. In some production settings, when comparing pen breeding to AI chair method, a slight decrease in productivity (600 inseminations per hour) was noted.
There are two ways to inseminate using an AI chair:
Although both methods eliminatethe catcher’s need to bend down to pick up the hens and hold them between his knees; the catcher is still exposed to some MSD risk factors. With both methods there is still a need to repeatedly twist from one side to the other. And with the ramp method, the catcher must also support some of the hen’s weight during the transfer.The inseminator’s working conditions are also improved. He no longer needs to stand, bend over or carry the semen doses during the insemination. However, with this method the inseminator must hold the hen between his legs during the insemination, exposing him to injuries caused by the flapping of wings from the hen.
