Panama Sheep

The Panama sheep is a breed of domestic sheep from United States. It was originated in the 1990s in Idaho by private sheep breeders.

The breed was actually named for the Panama-Pacific International Exposition, where it was shown early on in it’s history.

It is actually one of the only two recognized breeds of sheep which were developed in the United States by private sheep breeders.

The Panama sheep breed is the result of a cross between Lincoln ewes and Rambouillet rams. Following approximately five years of crossbreeding, rams and ewes were mated among themselves to establish the breed.

James Laidlaw developed this breed, who was a Scottish immigrant to the region.

James Laidlaw was seeking a large sheep, better suited to the range than the Merinos, which were most common in the late 19th and early 20 centuries.

In the year of 1951, a breed registry was formed, but it has been inactive and it’s unclear whether the majority of Panamas present today have not been crossbred.

The sole remaining flock that is known to be pure is one maintained by the University of Idaho. Read some more information about this breed below.
