Artificial Insemination Of Turkeys, H. L. Wiegers
Artificial Insemination Of Turkeys, H. L. Wiegers
Nebraska Agricultural Experiment Station: Historical Circulars
Artificial insemination should be used for turkeys when results from natural matings are unsatisfactory. There is no hard and fast fertility rule to follow and each breeder will have his own basis of appraisal for the different varieties of turkeys. But one can say that when fertility drops below 65 per cent it is time to take action.

Determining The Sex Of Day-Old Chicks, H. E. Alder
Determining The Sex Of Day-Old Chicks, H. E. Alder
Nebraska Agricultural Experiment Station: Historical Circulars
More than 2,000 years ago people were interested in determining the sex of the embryo in hatching eggs and the sex of day-old chicks. No method of determining the sex of day-old chicks (except of course in sex-linked chicks) was of the slightest value until the Japanese method was discovered and developed. About 1925 Japanese scientists discovered the presence of a rudimentary copulatory organ located on the ventral rim of the cloaca which was present in all day-old males and only a few day-old females.
