McNay Research and Demonstration Farm
As part of the 50th anniversary of the McNay Research Farm, cows were inseminated with semen from Angus bulls of the 1950s and the 1970/1980s. The goal was to produce calves from Angus bulls that were popular 50 years ago and 25 years ago for viewing at the McNay Research Farm’s 50th Anniversary celebration in September 2006.
