The swine industry has became more competitive in recent years, forcing producers to
maximize efficiency of production. A number of traits are included in overall efficiency …

Large White pigs from lines which had been divergently selected over 4 years for high and

Great improvements in both growth rate and carcass composition have resulted from
efficient breeding programmes employed in the pig industry in recent years. Selection …

Selection in pigs for either fast line F) or slow (line S) postweaning gain was replicated in
spring (SREP) and fall (FREP) farrowing groups. Littermate barrows were sampled from F …

Carcass composition was measured after six generations of divergent selection for lean
growth rate on ad-libitum and restricted feeding, lean food conversion and daily food intake …

The objectives were (1) to estimate responses from 28 generations of selection for increased
pigs born alive (BA) with additional selection for increased 180 d weight (WT) and …

Correlated responses in reproductive and carcass traits from a line of Landrace pigs
selected for increased 200-d weight along with a randomly selected control line were …

Responses to four generations of divergent selection in pigs for lean growth rate (LGS) with
restricted feeding were studied. The selection criterion was designed to obtain equal …

Abstract Lines of Large White (LW) and Landrace pigs were divergently selected for 4
generations for lean growth rate under restricted feeding. 1250 and 875 pigs of the 2 breeds …
