Polypay

Polypay is an American composite sheep breed developed in the late 1960s and 1970s at the United States Sheep Experiment Station near Dubois, Idaho. Its foundation combined Finnsheep, Rambouillet, Targhee, and Dorset genetics: prolificacy from Finnsheep, fleece quality from Rambouillet, range usefulness from Targhee, and extended breeding season and mothering ability from Dorset. Polypays are medium-sized, generally polled, white-faced sheep with white fleeces, used mainly as maternal ewes for commercial lamb production.

Commercial flocks use Polypay ewes when high lambing percentages and low-input range performance need to fit the same system. Their advantages depend on management that supports multiple births: adequate ewe condition before breeding, close attention at lambing, and enough feed for milk production. Purebred breeders commonly record lambing rate, lamb survival, fleece traits, udder quality, and ram soundness. Buyers comparing Polypay lines should ask how the flock performed under similar pasture, climate, and labor conditions rather than relying only on breed name or show type.
