Many ex-periments at state agricultural colleges show, however, that thecost of fattening in the Duroc-Jersey is slightly higher than in theother commonly raised breeds. Also on the killing floor the per-centage of offal is slightly higher than in other lard types. Prolific Breeder.—In the matter of breeding the Duroc-Jerseyis one of the most prolific of all breeds.
