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."
Sayaguesa The Sayaguesa is an endangered Spanish breed of domestic cattle. It is named for the comarca of Sayago in the province of Zamora, in the western part of the autonomous community of Castile and León, and is raised almost exclusively in that area. It may also be known as the Zamorana, the Moles de Sayago or the Castellana variedad Sayaguesa. It was traditionally kept mainly for draught work, but is now raised principally for meat.
