Occurrence of the genotype of the receptor gene for ryanodine (Ryr1) associated with sensitivity to stress in 5 Belgian porcine production systems ; Incidence du génotype du gène du récepteur à la ryanodine (Ryr 1) associé à la sensibilité au stress dans 5 filières porcines belges.

peer reviewed ; Porcine stress syndrome is related to a point mutation in Ryr1 gene encoding the ryanodin receptor. This syndrome involves mortality after stress conditions or poor quality meat. Five hundred and five individuals among 5 Belgian production systems were genotyped. This genotyping was performed by polymerase chain reaction-restriction fragment length polymophism (PCR-RFLP) or real time PCR. The results indicated that 22,4 % of the pigs were stress sensitive (TT genotype) and 77,6 % stress resistant (63,4 % CT heterozygotes and 14,2 % CC genotype). Statistical analysis allowed to...
