Treść
The aim of the study was to evaluate the effects of highly selen-ized yeast (SeY) or selenate (SeVI) on fatty acids (FA) profiles in musculus longissimus dorsi (MLD) and musculus biceps femoris (MBF) of male lambs. Lambs, divided into 3 groups of 6 animals each, were individually penned and fed for 35 days control diet containing 2% rapeseed oil (RO), 1% fish oil (FO) and 0.1% carnosic acid (CA) or experimental diets with additional 0.35 mg Se as SeY (the organic Se-form) or SeVI (the inorganic Se-form) per kg of the control diet. In lambs fed SeVI diet body weight gain after 21 and 35 days of feeding was increased; whereas in lambs fed SeY diet increased concentrations of C14:0, C16:0, C18:0, and the sums of atherogenic saturated fatty acids (SFA), thrombogenics SFA and all FA in MLD and MBF were noted. The content of t11C18:1 in MLD and MBF and was higher in lambs fed SeY and SeVI diets but the concentration of sum of long-chain polyunsaturated FA in MLD was decreased in comparison to the control group. The sum of conjugated linoleic acid isomers (ΣCLA) content in MLD was higher in SeY group in comparison to the control group. In both examined groups ΣCLA content in MBF was higher in comparison to the control group. In conclusion, the addition of inorganic or organic Se-chemical form into lambs’ feed based on RO, FO and CA differently modifies body weight gains as well as FA profile in examined muscles.
