Increasing the nutritional value of broiler chicken muscle fat using lupin meal in their diet

Popis výsledku v původním jazyce

The aim of the study was to determine whether the replacement of soybean extracted meal (50% and 100%) with meal from white lupin seeds (Zulika variety) affected the quality (fatty acid content) of breast and thigh muscle fat in hens and cockerels of fattened chickens (ROSS 308) in comparison with the control group, where the feed mixtures were based on soybean products only. In terms of muscle fat quality, evaluated on the basis of the representation of individual groups of fatty acids (in g/100 g fat), saturated (SFA), monounsaturated (MUFA), polyunsaturated n-6 FA and n-3 FA, it can be concluded that the SFA content increased in the breast muscle in hens and cockerels with the increasing content of lupin meal in the diet, on the contrary, it decreased in the thigh muscle. Similarly, in MUFA, the mean values in the breast muscle of hens and cockerels were statistically significantly higher (P ? 0.05) in the experimental groups compared to the control; no statistically significant differences were found in the thigh muscle. In the group of n-6 FA fatty acids, despite the fact that statistically significant differences were demonstrated between some means in individual groups of n-6 FA, based on our results, the influence of lupin diets on their content in breast and thigh muscle could not be clearly demonstrated. On the contrary, in the group of n-3 FA fatty acids, the effect of the administered experimental diets on the content of n-3 FA in the fat of breast and thigh muscle was clearly statistically significant (P ? 0.05), both in hens and cockerels. Based on the increased content of n-3 FA in muscle fat in experimental chickens, it can be stated that the administration of feed mixtures based on lupin meal in fattened chickens leads to an increase in the nutritional value of their muscle which is one of the important foods in human nutrition
