“…In the current study, the animal background and feeding regimens were derived from the studies by Kader Esen et al [15], Kader Esen and Elmaci [18], and Kader Esen et al [19,20]. We studied 202 later-born lambs from five different meat-type breeds [15 Males (M) and 36 Females (F) of Kıvırcık (K), 14 M and 33 F of Karacabey Merino (KM), 14 M and 14 F of Ramlıç (R), 15 M and 34 F German Black-Head Mutton × Kıvırcık (GBK), 11 M and 16 F of Hampshire Down × Merino crossbreed (HM)] whose mean weaning age was 90.5 ± 5.7 days (mean ± SD).…”

This study examined the relationship between GHE5 polymorphisms and growth and carcass characteristics of meat-type sheep breeds reared in Turkey. A total of 202 lambs were tested, consisting of five breeds. By SSCP analysis and nucleotide sequencing, 14 nucleotide changes (12 substitutions and two deletions) were identified in four variants of GHE5. In the coding region of GHE5, five substitutions occur, including c.1588C>Y(C/T) (Ala160Val), c.1603A>M(A/C), c.1604G>S(G/C) (Lys165Thr), c.1606A>W(A/T) (Gln166Leu), and c.1664C>Y(C/T). P3 female and P1 male lambs had the highest rump height at weaning, whereas P3 females and P2 males had the highest chest depth (p < 0.05). At yearling, P1 variant lambs have longer body length (BL; p < 0.05), wider leg circumferences, and thinner cannon bone perimeter (CBP) (p > 0.01), in contrast to P2 variant lambs, which have a shorter BL and thicker CBP. Furthermore, P2 had a greater percentage of neck, shoulder, and leg, P1 had a greater percentage of loin, and P3 had a greater percentage of rack, but there was no significant difference between them. A marker-assisted selection approach can be used to improve sheep carcass quality traits by taking advantage of the nucleotide substitutions found on GHE5 and the detected differences between variants.

“…CLPG lambs have higher feed efficiency and lower daily feed intake, resulting in lower production costs (Jackson et al, 1997). The use of the CLPG mutation in native sheep breeds in studies of introgression can lower the price of lambs for consumers and make the sheep industry more profitable (Esen et al, 2022a and2022b). There were almost no studies on the CLPG gene in Turkish native sheep breeds except for a few breeds and the findings of the current study were the first for the Akkaraman breed, which is the most common sheep breed in Turkey.…”

“…The CLPG causes muscle hypertrophy that is restricted to the pelvic and lumbar muscles with little or no effect on the anterior skeletal muscles (Cockett et al, 1996). As described in several studies, this gene also provides a higher leg score and carcass percentage, larger longissimus loins, superior leanness composition, higher leg values, higher percentage of dressing percentages, and optimal feed conversion, as well as higher body weight and Baron-Crevat indices (Jackson et al, 1997;Jawasreh et al, 2019;Esen et al, 2022b).…”

“…In addition, there is currently no study that describes the genetic structure of the Akkaraman sheep breed for the CLPG gene. Nonetheless, there is a growing interest in the CLPG gene in several native and cross breeds in Turkey (Esen et al, 2022a and2022b). Researchers reported that the Kıvırcık breed, an indigenous Turkish sheep breed, has the CLPG mutation.…”

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.

“…Therefore, incorporating heterozygous individuals that inherited the CLPG mutation from the sire in selection programs could be beneficial for improving carcass traits. The study of (Kader-Esen et al, 2022) suggests that the CLPG gene has implications for body indexes and morphometric characterization in meat-type sheep breeds. The findings support the feasibility of incorporating these body indexes, BCI and IBF, into breeding schemes, especially when utilizing marker-assisted selection approaches.…”

The callipyge (CLPG) gene is a candidate gene associated with meat production in sheep. The purpose of the study was to identify the association of polymorphisms in the 3'UTR of the CLPG (MEG3) gene in Albanian sheep breed with morphometric traits and body weight. A total of 87 individuals were studied regarding the morphometric traits and the polymorphisms of 3'UTR of the CLPG (MEG3) gene. The frequency of the mutated allele (T) was 0.339. The less frequent genotype was TT. The population was in Hardy Weinberg equilibrium. The fixation index was 10.2% indicating a moderate level of inbreeding. The results indicated no significant effect of this locus on morphometric traits and body weight. The preliminary data provided in this study suggest that the nucleotide change in the 3′UTR can be used in marker-assisted selection to increase the body weight of animals.
