    Poultry meat production as a functional food with a voluntary n-6 and n-3 polyunsaturated fatty acids ratio

  • Original language description

    The effect of different levels of linseed oils made either of flax cultivar Atalante with a high content of a-linolenic acid (612 g/kg) or of the cultivar Lola with the predominating content of linoleic acid (708 g/kg) in the chicken diet upon fatty acidpattern in the meat was studied. Cockerels Ross 308 were fed the diets containing 1, 3, 5 or 7 per cent of oil within the last 15 days of fattening. Breast meat (BM) and thigh meat (TM) without skin of 8 chickens from each dietary group were used for analyses. The relative proportions of fatty acids were expressed as percentages of total determined fatty acids. When feeding Atalante oil, the shares of n-6 fatty acids were highly significantly lower while those of n-3 fatty acids were higher; the ratioof n-6/n-3 polyunsaturated fatty acids in meat was narrower (P<0.001) than in chickens fed oil with a low content of a-linolenic acid. In BM and TM, the relative proportions of a-linolenic and g-linolenic acids were nearly the same, those

    Produkce drůbežího masa jako funkční potraviny s volitelným poměrem n-6 a n-3 polynenasycených mastných kyselin

  • Czech description

    Vliv obsahu 1, 3, 5 a 7 % lněného oleje v krmné směsi na složení masa byl sledován v pokusu s brojlery vykrmovanými od 25 do 40 dní věku. Byl použit olej z odrůdy Atalante s převažujícím obsahem kyseliny a-linolenové, nebo z odrůdy Lola s převažujícím obsahem kyseliny linolové. Rozdílným obsahem kyseliny linolové a a-linolenové v krmné směsi se dařilo upravovat poměr n-6/n-3 PUFA v prsní svalovině od 0,9 do 13,6 a ve stehenní svalovině od 1,0 do 17,2. Zařazením lněného oleje s vysokým obsahem kyseliny a-linolenové lze produkovat drůbeží maso jako funkční potravinu s prakticky libovolným poměrem n-6 a n-3 PUFA.
