All animals used in the 2 experiments remained
healthy and consumed all the feed offered them throughout
the experiment. The objective of this study was
to determine the nutritive value of EECM for growing
pigs. The SECM, which is the most commonly used
canola meal in the formulation of swine diets (Spragg
and Mailer, 2007; Canola Council of Canada, 2009),
was included in the study for comparison. The general
steps for solvent extraction of oil from seeds include 1)
seed flaking and cooking at 80 to 120°C for 15 to 20 min
to rupture the seed coat and cells, resulting in increased
oil availability; 2) pressing of the flaked and cooked
seeds to remove some oil (this process results in an increase
in meal temperature to 100 to 120°C); 3) solvent
extraction of the pressed seeds to remove additional oil;
4) desolventizing and toasting of the extracted meal at
approximately 105°C for 20 min to remove the solvent;
and 5) meal drying at approximately 105°C for 20 min
(Spragg and Mailer, 2007; Canola Council of Canada,
2009). For expeller-pressed oil extraction, the seeds are
flaked, cooked, and pressed as described for solvent extraction,
although the meal temperature can increase to
as much as 160°C during the pressing process because
of the increased pressure applied to maximize oil
