The experiment was performed at the pig breeding test station at Ploskov near Lány. A total of 72 (final crossbreeds of Czech Large White (paternal) × (Czech Large White (maternal) × Czech Landrace)) 69-day-old gilts and barrows with an average live weight of 28.7 kg were included in the experiment. The placing and housing of the pigs was carried
out in pairs, but both genders were separated. The pigs were fed with a complete feed mixture (CFM) containing three components (wheat, barley, and soybean meal) and premix. The diet was mixed separately for each group. Both sexes were divided into two groups according to linseed addition (Linumusitatissimum L.). The control group did not receive the crushed linseed supplement, and pigs from the experimental group were fed a diet enriched with linseed (150 g/kg). The nutrient composition
of the CFM is shown in Table 1. Transition of the
CFM from A1 to A2 and CDP (A1, A2, CDP are
types of mixed feeds fed to pigs with average live
weights of 28–35 kg, 35.1–60 kg, and 60.1–110 kg,
respectively) was realized continuously during the
test. The pigs were fed ad libitum. Each pig was
weighed monthly, and the feed intake per pen was
measured daily. The average daily weight gain, feed
intake, and feed conversion were calculated from
the observed values. At the end of the experiment,
the pigs were slaughtered in a commercial abattoir
using electrical stunning at an average live weight
of 110 kg. The transport lasted about 1 h.
