“…For example, 21 microsatellite loci clustered a total of 508 individuals belonging to 11 different Indian cattle breeds into six groups (Sharma et al, 2015). Similar results, in which cluster numbers were lower than studied number of breeds, were reported in sheep (Alarslan et al, 2021), goats (Nguluma et al, 2018) and chickens (Roh et al, 2020) as well due to high levels of genetic admixture. Besides, Maudet et al (2002) reported that accuracy of microsatellite markers to assign individuals to a certain breed could be decreased even to 6.5%.…”

Licensed under a Creative Commons Attribution 4.0 International License Developments in sequencing and SNP chip technologies have enabled scientists to obtain high-density genomic data from different livestock species, including cattle. Moreover, many bioinformatics tools are available to analyse high-density genomic data. Via these tools, several statistical approaches such as Principal Component Analysis and clusterin-based analyses could be conducted to reveal the genetic structure of cattle populations. However, revealing the genetic structure and selection signatures of Turkish cattle breeds is a new area of research, since the previous studies are limited with a few microsatellite data. On the other hand, rearing in different geographical and environmental conditions for a long period could possibly lead to more genetic variation in native Turkish cattle breeds compared to high-yielding culture breeds. These variations obviously cannot be detected by limited number of microsatellite markers, while Next Generation Sequencing is promising for further population structure studies. Hence this review aims to summarise previous studies and give a perspective of Next Generation Sequencing possibilities to reveal the population structure of Turkish cattle for further studies.

Abstract. Nurasih AD, Sumaryadi MY, Hidayah CN, Nugroho AP, Setyaningrum A, Haryoko I, Yuwono P, Sodiq A. 2023. Phenotypic characteristics of Sakub sheep as local livestock genetic resources. Biodiversitas 24: 5671-5675. Sakub sheep is an indigenous sheep with a giant body in the Brebes Regency. Phenotypic characterization is important to increase the population and productivity of Sakub sheep. By combining quantitative and qualitative data, this study will provide a comprehensive insight into the phenotypic profile of Sakub sheep. This study determined the quantitative and qualitative phenotypic characteristics of Sakub sheep. The Sakub sheep used were owned by smallholder farmers using the survey method with interview techniques, observation, and direct measurement of livestock. Samples were taken using purposive sampling in Pandansari and Wanareja villages, which have the largest sheep populations and are easily accessible. The sheep used were rams and ewes sheep in the age group of 1-1.5 years (P0), 1.5-2 years (P1), 2-2.5 years (P2), 2.5-3 years (P3). Phenotypic characteristics observed included quantitative characteristics of body size and qualitative characteristics of body morphology. Body size was measured using measuring tape and hanging scales, including Body Weight (BW), Body Length (BL), Whither Height (WH), Chest Girth (CG), Ear Length (EL), And Tail Length (TL). Body morphology includes head color, body color, face profile, and tail shape. Quantitative characters were analyzed using descriptive statistics, and qualitative characters were analyzed descriptively using relative frequency. The results showed quantitative phenotypic characteristics of Sakub sheep at the age of 1-1.5 years; 1.5-2 years; 2-2.5 years, and 2.5-3 years, such as body weight, body length, chest circumference, whither height, ear length, and tail length increased with age. The qualitative phenotypic characteristics of Sakub sheep are having a head and body with a combination of colors but dominant white, a convex head profile, no horns, and a thin and fat tail.

Objective: The study was conducted to identify body measurements that can serve as selection criteria in breeding programs for Eşme and Pırlak sheep breeds. Additionally, the study aimed to investigate the phenotypic correlation between live weight and body measurements. Material and Methods: The animal materials of both breeds were obtained from farms that are considered multiplier flocks in the breeding programs. The animal material used in this study consists of a total of 612 sheep, including 311 Eşme sheep from three breeders and 301 Pırlak sheep from three breeders, sourced from six farms in Uşak province. In the study, data were collected on various physical characteristics of the animals during the mating period, including their head size (such as forehead width, head length, and ear length), body size (such as chest width, rump height, withers height, back height, chest depth, chest girth, and body length), and weight at the time of measurement. Results: The findings revealed that systematic environmental factors, such as breed, farm, gender, and age classes, have a statistically significant effect on the live weight and body measurements. On the other hand, positive correlation coefficients were obtained for live weight and body measurements. Conclusion: The findings revealed that utilizing body measurements, particularly chest girth, as selection criteria in breeding programs aimed at improving growth characteristics can have a positive impact on the live weights of animals. The observation that the Eşme breed exhibited higher values than the Prılak breed in terms of live weight and certain body measurements suggests that this breed holds significant potential for meat production in the region.
