“…[26] also found that supraspinatus, longissimus, and semitendinosus muscle color was lighter for CLPG carcasses when compared with normal carcasses. In another hand, the loins of the CLPG lamb have stability of color, while exhibiting lower tenderness compared to loins from non-CLPG phenotype lambs [29].…”

Aim: This study was designed to introduce the callipyge (CLPG) and 50% of Rambouillet sheep genes to improve meat quality and quantity of Awassi (AW) sheep. Materials and Methods: The CLPG mutation was introduced into the AW sheep through frozen semen of homozygous Rambouillet rams for the CLPG mutation. Four ram lambs from the first-generation Rambouillet callipyge Awassi (F1-RCA) and five from pure AW were recruited for a fattening trial conducted in individual pens using standard ration, following which ram lambs were slaughtered for carcass and meat evaluation. Results: Final body weight, dry matter intake, average daily gain, and feed conversion ratio were significantly higher in F1-RCA than AW. Hot and cold carcass weights and the other carcass cuts' weights, except for the fat tail, were heavier in F1-RCA than AW. There was no difference in dressing percentage between the two genetic groups (p>0.05). All non-carcass components' weights, except spleen, kidney, and testis, were higher in F1-RCA. Total lean, total bone, and intermuscular fat weight were greater in F1-RCA, but bone-to-lean ratio was lower in F1-RCA when compared with AW (p<0.01). No differences (p>0.05) were observed in all meat quality parameters for muscle longissimus with the exception of pH, redness color, and tenderness that were lower (p<0.05) in F1-RCA than AW. F1-RCA lambs had larger longissimus muscle area (30.9 vs. 16.9 cm2) and less leg fat depth (11.1 vs. 17.4 mm). Conclusion: The implications of this research show the potential of 50% of Rambouillet genes and the CLPG mutation to improve growth and meat characteristics in AW-Rambouillet crosses and can be used further to develop a meat-type AW with improved productivity and muscle mass.

“…The CLPG gene plays an important role in sheep breeding because it ensures a higher carcass weight with the desired fat content of the carcass. Several studies have shown that the carcasses of lambs carrying a CLPG mutation are more desirable and profitable than those without the mutation (Jawasreh et al, 2016;Penick et al, 2017). Despite CLPG gene's important influence on meat quality, there have been few studies on the CLPG gene in Turkey.…”

Callipyge is a candidate gene with a significant effect on meat quality and growth in sheep. The aim of this study is to investigate the polymorphism of the Callipyge gene (CLPG) in Akkaraman breed. In the study, DNAs obtained from blood samples of 50 Akkaraman sheep were used as study material. The CLPG/Faq1 polymorphism was examined in all individuals using the method PCR-RFLP. Only A allele and AA genotype were detected after PCR-RFLP procedure. This is the first study in which Callipyge gene polymorphism was investigated in Akkaraman breed, and the findings show that Akkaraman breed has a monomorphic structure in terms of Callipyge/Faq1 polymorphism.
