Abstract

On May 13, 1963, a five-year-old dairy cow gave premature birth to a litter of five, two males and three females. They were calved about 25 days earlier than expected, but were allhealthy.
The three females were normal in outward appearance. Autopsy of each of them disclosed, however, that the uterus and vagina suffered from hypoplasia and that the gonad was an ovotestis histologically.
Therefore, they were presumed to be devoid of reproductive capacity.
