The Bündner Oberländerschaf (also known as Grisons (French), Graubünden (German)) is a domesticated breed of sheep in Switzerland. As of 2007, there were less than 1,100 but the population is increasing and used primarily for vegetation management.[1]
The Bündner Oberländerschaf displays white, brown or silver-grey. The head is slender and is bare. Rams have substantial horns while ewes have small horns or are polled (hornless). Both sexes display rather primitive behavior. Multiple births are common.[2]
When mature, rams weigh on average 72kg (159lb) and ewes 50kg (110lb). After reaching maturity, rams grow to 72cm (28inches) and ewes 68cm (27inches) at the withers.[1]
