Osborndale Ivanhoe (1952–1970), Holstein bull owned by Frances Osborne Kellogg and mated 100,187 times and whose semen was shipped all over the world. [40] Toystory (2001–2014), Holstein bull whose semen has sold more than 2.4 million units worldwide and has been estimated to have sired over 500,000 offspring [41]
The Swiss Holstein is the Swiss variant of the international Holstein-Friesian breed of dairy cattle. It results from systematic cross-breeding , through artificial insemination between 1966 and 1973, of the traditional dual-purpose black-pied Fribourgeoise from the Canton of Fribourg in western Switzerland with Canadian Holstein stock.
The semen was sold around the world, including in the Americas, Europe, Japan, China, Russia, and Pakistan. Toystory has sired an estimated 500,000 offspring in more than 50 countries. In May 2011 he became the most productive Holstein ever, surpassing the world record by producing his 1.7 millionth unit of semen at just 10 years of age.
Kian (11 June 1997 [1] – 2013) [2] was a red-and-white breeding bull. He was the first red Holstein bull from the Netherlands whose semen was sold worldwide; more than a million units of his frozen semen were sold. He was owned by the Dutch-Belgian company CRV . [3]
The acknowledged specialization for jumping capacity in the breed sometimes means the quality of the walk and trot suffer, though this is not the rule. [6] The canter, which is typically light, soft, balanced, and dynamic, is the best gait of the Holsteiner. [2]
In about 1970, importation to Sweden of semen from American Holstein-Friesian bulls began. [4] Between 1970 and 2005, the proportion of Holstein alleles in Swedish Friesian cows rose from 6% to more than 90%; in bulls the proportion rose even more. [6] The original Swedish Friesian type has become very rare, [4] and should perhaps be considered ...
An American breeder, Richard Gradwohl, has developed eighteen different strains of miniature cattle. [3] Miniature Galloway, Hereford and Holstein have been bred. [2]: 245 [3] In the United States, small zebuine cattle deriving from stock imported from Brazil, the Dominican Republic and Sweden may be registered as "Miniature Zebu"; [2]: 245 in Australia, similar cattle may be known as "Nadudana".
A bull is typically ready for slaughter one or two months sooner than a castrated male or a female, and produces proportionately more and leaner muscle. [24] Frame score is a useful way of describing the skeletal size of bulls and other cattle. Frame scores can be used as an aid to predict mature cattle sizes and aid in the selection of beef bulls.
