Suffolk Sheep Ewes The Suffolk Sheep Ewes are mostly raised for meat and wool production, particularly when crossed with the offspring of a mountain ewe. The lamb created when a Suffolk Sheep ram is crossed with the half-bred ewe is considered perfect for the meat manufacture because usually, they have good conformation.

    Purebred Rambouillet (n = ), purebred Polypay (n = ), and crossbred Romanov-White Dorper x Rambouillet (RW-RA; n = ) ewes were produced from locally adapted Polypay and Rambouillet ewes and mated to Columbia, Suffolk, Columbia x Suffolk or Suffolk x Columbia sires for up to 4 lambings beginning at 1 yr of age. Romanov crossbred ewes had the heaviest litters at 20 weeks of age per ewe lambing for both dam- and nursery-reared lambs, followed by Finnsheep, then Dorset and Montadale, and finally Texel. Fleeces of crossbred ewes by Montadale and Texel were heaviest.
