Independent of treatments the overall performance of
the pigs was good. Mean daily gain was 829 g, and percentage
of lean meat in the carcass was 60.7. No health problems
appeared during the experimental period from 40 kg
live weight until slaughter at a live weight around 108 kg.
Only 2 of the 160 pigs were discarded due to health problems
or death during the experiment. A total of 154 pigs
completed the production period according to the experimental
plan, and 152 pigs completed all the meat quality
measurements. Differences in live weight and warm carcass
weight were based on the conditions of delivery to the abattoir
at Research Centre Foulum. The pigs were slaughtered
on only two days per trial, which in combination with the
differences in daily gain between treatments
