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."
Madura cattle Madura cattle are a stable, inbred hybrid of Zebu and Banteng (Bos javanicus). They originated on the island of Madura near northeastern Java, where the original cattle population was Banteng, very similar to Bali cattle. Sinhala cattle, a Zebu breed from Sri Lanka, were introduced more than 1500 years ago, and the cross was found to be better than either of the original breeds. Some sources say the Zebu component was Ongole Cattle from India. The colouration is reddish brown with non-specific white patterning on the back and rump. They are a small breed, bulls having a mature weight of 250 to 300 kg, used for racing and are sometimes called dancing cattle. In 2002 the population was estimated by the FAO at 900,000. Efforts are being made to conserve the breed on Sapudi island
