Four sets of chickens were included in four cycles of the commercial fattening. The fatty acid pattern of feed mixtures used in the cycles varied. The linoleic: alpha-linolenic acid ratio in the diet varied in the range 5.2-41.0. Total lipid content in breast and thigh meat of the chickens was determined after the tissue extraction. The different composition of the feed mixture did not influence cholesterol content in breast or thigh meat. However, cholesterol concentration in total lipids increased both in breast meat and thigh meat with decreasing linoleic acid content and with increasing palmitic acid content in the diet. Linoleic acid and alpha-linolenic acid content differed significantly between the feeding cycles both in breast and in thigh meat. Polyunsaturated fatty acid (PUFA) n6/n3 ratio of the diet influenced PUFA n6/n3 ratio in breast muscle but not in thigh muscle.
