Popis: | Consumption of chicken meat enriched with bioactive compounds such as n-3 polyunsaturated fatty acids (PUFAn-3), vitamin E (vE) and selenium (Se) can help prevent many diseases and can be used to deliver those substances to humans. This might be of importance as chicken meat consumption is increasing worldwide. The effects of enriching chicken meat with PUFAn-3, vE and Se through dietary interventions were studied in rats. Four groups of Ross 308 female broilers from day 22 to day 35 of age were fed control diet (L) that contained lard and 80 mg vE and 0.3 mg Se/kg, or diets that contained rape seeds and fish oil with the same level of Se and vE as in the control diet, the same level of Se as in the control and 150 mg vE/kg, or 150 mg of vE and 0.7 mg Se/kg. Broiler carcasses were boiled, deboned, lyophilized and pooled by group. Boiled edible components of chicken carcass (BECC) were included (240 g/kg) in the diets fed to four groups of ten 10-week-old Wistar male rats for 8 weeks. Inclusion of BECCs modulated dietary fatty acid profile in the rat diets. Feeding these diets did not influence parameters related to growth or relative weights of internal organs in the rats. Feeding BECCs with lower PUFAn-6/n-3 decreased the n-6/n-3 ratio in the rat brain and liver, and increased the proportion of docosahexaenoic acid in the brain lipids. Liver cholesterol level was similar among the experimental groups, whereas the concentration of vE in the liver of rats fed BECC with increased vE levels was higher than that in the rats fed BECC with the basal vE level. Haematological and biochemical parameters in blood were within the normal range for rats, but a few rats showed a tendency towards increased levels because of the higher vE and Se level. The health-promoting effect of feeding rats PUFAn-3 enriched BECC was more pronounced when an increased dietary level of vE was used, but the increased level of Se did not provide the rats with additional benefits. Thus, the findings indicate that BECC enriched with PUFAn-3 and vE by a dietary intervention is a functional food with great potential of implementation. |
