were no significant differences between any of the treatments for
any carcass characteristics measured (trim, hot carcass weight,
dressing percentage, backfat, loin muscle depth, percent lean).
- Fibrous feed ingredients can be included at 5% or less of the
total diet without depressing ADG or feed efficiency. MSE can
significantly improve ADG and/or feed efficiency in
growing-finishing pigs. Improvements from both low fiber inclusion
and MSE were additive.
