摘要

Title of the Paper: In this investigation the fatty acid pattern of the adipose tissues back fat (devided in dorsal and ventralcompartment), leaf fat and intermuscular and the total and phospholipids of the of different MHSgenotypesand sexes of the Piétrain race have been compared. There were available 60 animals with equalnumbers of the three MHS-genotypes (NN, Np, pp) and both sexes (castrates, gilts) (liveweight at the end offattening: 150 kg).The decreasing presence of the stress allele p (pp > Np > NN) as well the castrates compared with the gilts werecombined with increasing content of saturated and monounsaturated fatty acids and decreasing content ofpolyunsaturated fatty acids in all adipose tissues and in the total and phospholipids of the and thuswith better technological quality.The results should additionally cause the selection stress resistent pigs of the Piétrain race.
