Smith, William Lloyd 01 May 1956 (has links)
Artificial insemination of dairy cattle has become a major part of the dairy industry during the past 1.5 years. There has been a steady increase in the number of cows serviced each year since the first artificial breeding association was organized in the United States in 1938. In 1952 there were 4,238,245 cows bred artificially. In 1953 there were 4,845,222 and in 1955, artificially cows bred numbered 5,250,000.
