Advances in molecular genetics have allowed the identification of genes that can enhance livestock production. The aim of this study was to investigate possible relationships between the calpastatin (CAST) Hha1 gene polymorphisms and growth performance, carcass characteristics, and meat quality in Awassi sheep. A total of 87 blood samples were collected from two-week-old Awassi ram lambs. The amplification of the CAST Hha1 gene yielded a fragment of 622 bp. Three CAST genotypes were found in Awassi sheep: MM for two fragments (385 bp and 281 bp), MN for three fragments (622 bp, 385 bp, and 281 bp), and NN for only one fragment (622 bp). The M and N allele frequencies of the CAST Hha1 genotypes were 0.765 and 0.235, respectively, while the genotypic frequencies of MM, MN, and NN were 0.586, 0.356, and 0.057, respectively. Based on CAST Hha1 gene polymorphisms, three groups of lambs (MM: n = 8; MN: n = 6; and NN: n = 3 genotypes) were subjected to a fattening period of 70 days to investigate growth performance and meat characteristics. Only the final body weight and longissimus muscle width were significantly different between the three genotypes, while no significant differences were detected in any other carcass characteristics and meat quality parameters. In this study, new variants were observed in CAST using the Hha1 restriction site, potentially assisting in Awassi sheep breeding and selection programs to improve final body weight and longissimus muscle width.

This study was conducted to determine muscle fiber characteristics and their effect on some meat quality parameters in Longissimus dorsi (LD) and Semitendinosus (ST) muscles from kids of some Turkish native goat breeds. Male kids of Hair (n=6), Angora (n=6), Kilis (n=6) and Honamli (n=6) (pure breeds) were used as experimental animals. All kids were slaughtered at 3 months of weaning age and muscles samples were collected for determination of type I, IIA and IIB muscle fibers and some meat quality parameters. It was found that type IIA fiber number of Hair and Honamli kids were higher than those of other breeds in LD muscle. Similarly, Hair kids had higher number of (P less than 0.05) type IIA in ST muscle compared to other breeds. Generally, there were negative correlations between tenderness, pH and number of muscle fiber types in LD and ST muscles of all breeds (P less than0.05). Also, there were positive correlations between intra muscular fat and number of muscle fiber types in LD muscles of all breeds (P less than 0.05). Conclusively, kids of Turkish native goat breeds had different muscle fiber characteristics which can affect meat quality.

Abstract. The aim of this study was to determine growth performance, carcass and meat quality of Karayaka female lambs born in different seasons. Winter born (breeding season; n=15) and autumn born (out of the breeding season; n=15) singleton female lambs were used in the study. Birth and slaughter weights of lambs in both groups were similar, but the weaning weight of the autumn born lambs was higher (P<0.05). The autumn born lambs had lower carcass yield, lung, spleen and gastrocnemious muscle weights (P<0.05), but higher liver, kidney, empty reticulo-rumen, empty small intestine, internal fat, suprarenal fat weights and a higher fat thickness over the longissimus dorsi muscle (P<0.05). Additionally, the winter born lambs had higher cooking loss, drip loss and shear force values (P<0.05), but lower dry matter and intramuscular fat (P<0.05) in longissimus dorsi and semitendinosus muscles. There were significant differences between both groups in terms of meat colour characteristics (P<0.05) except b* values for longissimus dorsi at 1 h and for semitendinosus at 24 h. The results suggest that Karayaka female lambs born in winter and autumn seasons have different meat quality parameters and growth patterns at pre- and post-weaning.
