The objective of the current research was to evaluate genetic relationships among indigenous Turkish Karayaka sheep subpopulations as well as genetic diversity. Our results show a high genetic differentiation among subpopulations, which is quite interesting when considered for only one breed. This differentiation should be taken into consideration when preparing conservation programs and future breeding strategies.

The aim of this study was to compare the chemical composition and fatty acid content of the muscle tissues of lambs and adult sheep. The results support the inclusion of dietitian-recommended mutton into the human diet and the promotion of the production of meat from adult animals as a high-value product. The sheep industry could benefit economically, particularly in countries where this meat type has not enjoyed a high standing in consumer preferences.

In order to reveal whether peroxisome proliferator-activated receptor γ coactivator-1 α (PPARGC1A) gene is involved in the process of milk fat synthesis in buffalo, we analyzed the function and expression of this gene here. The results showed that buffalo PPARGC1A played a key role in the lipid synthesis of mammary gland. Eight SNPs were found in its coding region, of which three were non-synonymous. This study revealed that the PPARGC1A is closely related to buffalo milk fat synthesis.
