Physical dehorning of dairy cattle is practiced to protect animals and their handlers. Genetic analyses have identified variants that are associated with hornlessness (referred to as 'polled') in ...
A horned bull from a control group is flanked by two hornless offspring of a genome-edited bull. (Alison Van Eenennaam/UC Davis) For the past two years, researchers at the University of California, ...
Hornless cows which are unable to gore farmers or threaten dog walkers are being bred by scientists. Animal geneticist Dr Alison Van Eenennaam, of the University of California, discovered it is ...
The newly-bred hornless yaks live in the Datong Yak Breeding Farm, Northwest China's Qinghai province. [Photo provided to chinadaily.com.cn] A Chinese research team has managed to breed the first ...
Researchers have used genome editing to generate hornless cattle, which then pass on the trait to their offspring. The absence of the horns means they cannot use them to injure other animals - or ...
It is possible to naturally breed a hornless dairy cow. Angus beef cattle don't have horns, and when they mate with dairy cattle, half of their offspring won't grow horns either. The problem is ...
But a group of researchers from the University of California, Davis has developed a method to remove the horns through gene-editing. The team inserted a gene from the naturally hornless Angus breed to ...
A study into a fossilized skull found at Badlands National Park, which eventually led to the novel findings, suggested that all of these deer were hornless and roughly the size of a modern ...
The new deer has been called Santuccimeryx, meaning “Santucci’s ruminant." A new genus of tiny, hornless deer that lived in South Dakota during the Oligocene Epoch approximately 32 million ...
The Park Service said in a press release that the tiny, hornless deer lived in South Dakota about 32 million years ago, during the Oligocene Epoch. It belongs to an extinct family of deer that are ...
