Comparison of Large White and Duroc boars as terminal sires

  • S.P. Simpson (a1), A.J. Webb (a2) and S. Dick (a1)


Pig improvement schemes have generally concentrated on producing lean, efficient pigs with rapid growth rates, but there is growing concern that pork is being produced which is too lean and that meat quality is deteriorating. The American Duroc breed may have an advantage over the Large White and Landrace breeds in eating quality through a higher level of intra-musclar fat. This study compares production and carcass traits in a three breed cross with Duroc and Large White boars as terminal sires and Large White x Norwegian Landrace dams. Pairs of sibs were penned and tested together and fed ad libitum or on a time based scale, and carcass measurements were taken at the end of test.
