Lineback cattle
From Wikipedia, the free encyclopedia
Lineback cattle are a distinctive breed of dairy cattle derived from the Holstein breed, and to whom the Randall cattle bear a strong resemblance. While not a commonplace breed, they are found in small numbers as "productive pets" amid larger numbers of other dairy cattle breeds on dairy farms throughout North America.
Known for their distinctive coloration, the Lineback is primarily a black base and nose with a skunk-like stripe along the spine. Due to the rarity of the pure-strain breed, variations such as red lineback and animals with a heavily speckled pelt instead of a distinct stripe occur from time to time.
Due to a notoriety for producing large calves that can result in calving dystocia, the breed is often cross bred to other dairy cattle, though the coloration trait is generally dominant in offspring.
