A new model of bird holder and semen receptacle for collecting semen from the cock



A new model of bird holder and semen receptacle for collecting semen from the cock



Bull Hiroshima Agric Coll 2(1): 17-24



This new model was constructed for collecting fowl semen without changing its genuine nature when the massage method is applied. The design of the holder presented keeps a bird completely in suspending pose without footing on the base whereas its abdomen is fully exposed to the operator's hand. The bird mounted on this holder can never attempt escape; upon masage it shows an ejacultory response within a few minutes, presumably in part due to the conditioned reflex. This rapid response naturally gives less opportunity of admixture of feces and urates. The application of the holder of this type enables the attachment of a funnel-shaped receptacle over the vent of the bird for catching the semen directly from it. During the cold season, the receptacle can be equipped with a container holding water of 41[degree] to 42[degree]C for protecting sperms from thermal shock. On examining, the semen thus collected was approximately 2 times larger in volume per ejaculate and 7 times smaller in bacterial counts as compared with that obtained by the other methods. Since no "milking" process is necessary in this method, occasional admixture of transudates, blood cells etc. can be eliminated. By employing the above equipment, the fowl semen can be collected in a more natural state than by the massage methods.
