Carcass Fatty Acid Composition
For backfat, pigs fed the 2 diets containing 15% DDGS
had greater (P < 0.02) concentrations of C18:2n-6 and
PUFA and lesser (P < 0.05) concentrations of C18:1
cis-9 and SFA than pigs from all other treatments (Table
7). As a result, PUFA:SFA and UFA:SFA of backfat
were greatest (P < 0.05) in pigs fed DDGS. Pigs fed
EESM diets had greater (P < 0.05) concentrations of
C18:2n-6 and PUFA and decreased concentrations of
C18:1 cis-9 and SFA compared with pigs in the control,
low CWG, or high CWG diets. Pigs fed EESM had a
greater (P < 0.05) PUFA:SFA than pigs fed the control
diets or the CWG diets. Pigs fed low or high CWG diets
had C18:2n-6 and total PUFA concentrations in backfat
that were not different (P > 0.10) from those of pigs
fed the control diet; however, SFA concentration was
less (P < 0.05) for pigs fed CWG diets than those fed
the control diet. In contrast, pigs fed low or high CWG
diets had greater (P < 0.05) MUFA concentration in
backfat than pigs fed diets with EESM or DDGS. Pigs
fed low or high CWG diets had a PUFA:SFA similar (P
> 0.10) to that of pigs fed the control diet. Pigs fed the
