BATON ROUGE, La. (AP) - Scientists at the LSU AgCenter have
produced calves from Angus bull semen that has been frozen for more
than 40 years.
Professor Robert Godke says some of the calves were sired by
semen collected and frozen from bulls in the late 1960s.
Godke says semen from 25 bulls - some now deceased - was
collected, processed and stored in liquid nitrogen in the 1960s and
in succeeding years into the 2000s.
Godke, who led the study, says they believe normal, viable
calves have been produced from some of the longest-stored frozen
semen ever reported in the scientific literature.
