Association and Polymorphism of the APOA5 Gene Related to Carcass Characteristics and Lamb Quality in Sheep

The apolipoprotein A-V (APOA5) gene is a candidate that plays an important role in carcass characteristics and lamb quality. This study aimed to association polymorphism of the APOA5 with quality sheep. breed sheep were used 100 consisting Thin Tailed Sheep (TTS) (n=55), Compass Agrinac (CAS) (n=10), Garut (GS) (n=18), Composite (GCS) (n=8), Barbados cross (BCS) (n=9). Identification was performed using PCR-RFLP method GLM analysis. results showed (g.26929941 C>T) polymorphic TTS, CAS, GS, GCS, while BCS monomorphic. has three genotypes (CC, CT, TT). Association significantly (P<0.05) associated percentage length. also significant pH dan tenderness. TT genotype greater length than CC CT genotypes. tenderness helps improve
