Polled strains have been developed of many cattle breeds which were originally horned. This has usually been done by crossing with naturally polled breeds, most commonly Angus and Galloway cattle. For example, polled Jersey cattle originated in Ohio sometime prior to 1895. Two strains were developed, the first to appear being founded by crosses ...
One of the first polled Holstein was a bull named ‘Lophelias Prince’ born in April, 1889. He was found in Massachusetts, US. This particular bull was the first recorded but there had been reports of polled Holsteins previous to the records. Not fully aware of this trait, polled Holsteins were often classed differently than horned Holsteins. [1]
The gene for scurs is inherited separately [3] from the polled gene in cattle. [4] Not all polled animals lack the scur gene. Since horned is recessive to polled, [5] no horned cattle carry the polled allele, but they may also carry scurs. In cattle, genetic expression of the scur gene is different from that of the dominant polled gene, in that ...
The polled gene can occur naturally, and certain breeds lack horns. Although polling is common among cattle and sheep, some varieties of livestock species cannot easily be bred to lack horns naturally. In one case, the poll gene in goats was linked to hermaphrodism in a single study several decades ago, although fertile polled goats have been ...
Polled Holsteins have the dominant polled gene which makes them naturally hornless. The polled gene has historically had a very low gene frequency in the Holstein breed. However, with animal welfare concerns surrounding the practice of dehorning, the interest in polled genetics is growing rapidly. [32]
Neat (horned oxen, from which neatsfoot oil is derived), beef (young ox) and beefing (young animal fit for slaughtering) are obsolete terms, although poll, pollard and polled cattle are still terms in use for naturally hornless animals, or in some areas also for those that have been disbudded or dehorned
Their short coat is generally red in colour, although variations from golden honey to dark red can occur. The red pigmentation in Droughtmasters helps protect the cattle from cancer eye, sunburnt udders and photosensitisation. The cattle may be either horned or polled; the majority are polled and exhibit only a moderate hump. They have an ...
The cattle are a solid deep cherry-red in color, with only minimal traces of white on the underline; they may be either polled or horned. [3]: 290 They are hardy, with good resistance to ticks and bloat, and a good tolerance for heat. [8]
