Abstract
CRC (Calcium Release Channel) or RYR1 (Ryanodine Receptor 1) locus is characterised by two allele forms: N (dominant or C allele) and n [recessive mutated allele, also known as ‘halothane sensitivity’ allele (Haln) or T allele]. In pig, Haln presence in homozygous condition is responsible for PSS (Porcine Stress Syndrome), which, among the other things, causes PSE (Pale Soft Exudative) myopathy. PSE meat is not suitable both for fresh consumption and transformation. In order to individuate the possible presence of mutated allele and its incidence in some ancient autochthonous genetic types (AAGTs), a genetic screening was performed on a total sample of 327 pigs belonging to Casertana (CT), Calabrese (CA) and Nero Siciliano (NS) AAGTs. The results of typification evidenced a higher incidence of mutated allele in CA (22%) in comparison with NS (8,7%) and its absence in CT AAGT.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
