Which breed of dairy cattle originating in Holland produced the world-record breaking amount of semen for a bull in 2012?
Toystory (bull) Toystory was a Holstein bull that has sired an estimated 500,000 offspring in more than 50 countries around the world. He was owned by Genex Cooperative Inc and he was housed Shawano, Wisconsin. In 2012 Toystory produced a world record-breaking 2 millionth unit of semen at eleven years of age and was the first Holstein bull in history to achieve this mark. This surpassed the previous world record of 1.7 million units of semen set by a Dutch Bull named Sunny Boy. Over his lifetime Toystory produced 2.4 million units of semen. Toystory died on Thanksgiving day in 2014 at thirteen years of age. "The death of TOYSTORY means the passing of the industry's most prolific sire," stated Keith Heikes, Genex Chief Operating Officer, "This bull was one of a kind for many reasons."
Buelingo The Buelingo is a modern American composite breed of belted beef cattle. It was created in North Dakota, in the United States, in the 1970s, and is named for one of the breeders, Russ Bueling. The hybridisation started from animals of Angus and Shorthorn type, which were crossed with Limousin and a Dutch Belted bull to fix the gene for belting; this was purely for appearance. Chianina blood was later added to improve the composite breed. In 1989 a breed society, the Buelingo Beef Cattle Society, was started.
