grape pomace, fatty acids, geese, abdominal fat


It was published, that grape pomace has a positive effect on the animal organism and is also a rich source of fatty acids. The inclusion of grape pomace in the geese feed mixture was the main objective of the following experiment. The addition of grape pomace into the feed mixture was used to investigate to what extent will affect the fattening parameters of geese and the profile of fatty acids analysed from the abdominal fat of geese. The experiment was carried out on 20 geese (Czech goose breed). Two groups were formed to obtain the same average weight. The average weight of the experimental group at the beginning was 1857 ± 196 g. The average weight of the control group was 1872 ± 248 g. For 49 days, both groups were fed a commercial complete feed mixture for geese fattening while in the experimental group 1% of the feed mixture was replaced by dried grape pomace. The average weight of geese of the control group at the end of fattening was 5579 ± 770 g and of the experimental group 5752 ± 752 g. The addition of dried grape pomace to the feed mixture in the fattening of geese increased the average daily weight gain of geese by 5.2% (P˃0.05), liver weight by 22.5% (P˂0.05) and increased the content of monounsaturated fatty acids by 2.5% (P˃0.05), especially oleic acid by 3.0% (P˃0.05). A reduced content of polyunsaturated fatty acids by 1.5% (P˃0.05) and decreased saturated fatty acid content by 3.2% (P˃0.05) was detected in the experimental group. It can be concluded that the addition of grape pomace affected the liver weight of fattened gees, while the effect on fatty acids composition was insignificant.
