“…The HD value in this study is almost the same as fat-rumped sheep in Ethiopia (0.99) [ 47 ], five Egyptian sheep breeds (0.968) [ 37 ], four Polish sheep breeds (0.9720) [ 39 ], Savak Akkaraman sheep (0.995) [ 48 ], Iranian indigenous sheep (0.996) [ 31 ], Karayaka sheep (0.998) [ 33 ], and Mongolian native sheep (0.93) [ 3 ]. The K value in this study is similar to 10 Iranian indigenous sheep breeds (25.23) [ 31 ], but higher than five Egyptian sheep breeds (17.14782) [ 37 ], Romanian Racka sheep (6.70488) [ 49 ], and Savak Akkaraman sheep (7.068) [ 48 ].…”

“…Most GRT and PRG sheep are classified as Hap A, but there are GRT sheep (GRT1 and GRT2) and PRG1 sheep that are classified as Hap B. This pattern is similar to that observed for the five Egyptian sheep breeds [37], Romanian Racha Sheep [49], and Iberian sheep [57] where Hap B is predominant over Hap A. However, this in contrast to the observations of the four Nepal indigenous sheep breeds [51], Tibetan sheep [26], and native Mongolian sheep [3], where Hap A is predominant over Hap B.…”

Background and Aim: Java Island is one of the islands in Indonesia which has local sheep breeds with specific characteristics and native development geography in certain regions. This study aimed to determine the genetic profiles and maternal origin of six local sheep breeds on Java Island. Materials and Methods: This study was conducted by identifying the profiles of complete mitochondrial DNA (mtDNA) displacement loop (D-loop) region sequences on a total of 22 individual in six local sheep breeds on Java Island, including Javanese thin-tailed (JTT), Javanese Fat-Tailed (JFT), Batur (BTR), Wonosobo (WSB), Garut (GRT), and Priangan (PRG) sheep. The D-loop region was amplified using specific primers, and the polymerase chain reaction (PCR) was performed. The PCR products were purified and sequenced. Results: The mtDNA D-loop analysis identified 21 haplotypes in the analyzed 22 animals with 123 polymorphic sites (V) consisting of 60 singleton variable sites (S) and 63 parsimony informative sites (P). Within all breeds tested, the haplotype diversity, the average number of pairwise differences (K), and nucleotide diversity (Pi) were 0.99567, 25.36364, and 0.02153, respectively. The genetic distance (D) within groups and between groups was 0.001-0.006 and 0.004-0.036, respectively. The phylogeny resulted in the presence of two haplogroups (Hap), which are 5 Hap A and 16 Hap B. All JTT, JFT, BTR, and WSB breeds were in the same cluster in Hap B, whereas GRT and PRG breeds were in clusters in both Hap A and Hap B. Conclusion: The high genetic diversity in six local sheep breeds on Java Island suggests that they originated from different genetic sources. JTT sheep have closer genetic relationships to JFT, BTR, and WSB sheep, and they are close to European sheep, whereas GRT sheep have closer genetic relationships to PRG sheep. Both are closer to Asian sheep than to European sheep.

“…The reason for the differences between the populations in Serbia and Hungary may be geographical isolation and different genetic makeup. According to Dudu et al, (2016) starting from 1960, Hungary imported sheep from Romania and afterwards the breed was exposed to an intensive process of selection and conservation.…”

The intensification of sheep production, by permanent genetic selection and the development of breeding technology, has led to the creation of highly productive sheep breeds. In this way, many highly productive breeds were created which could demonstrate their high production potentials only under perfect conditions of nutrition, accommodation and care. Preservation of indigenous breeds is of great importance in order to protect and safeguard those breeds and, in this way, it is possible to restore some of the characteristics that are lost during intensive selection, which are mostly related to resistance. The Racka sheep (Serbian: Vitoroga žuja) is considered to be an autochthonous breed and a genetic resource in the Republic of Serbia. As a primitive breed with low productivity, it offers no economic profitability and, thus, there is no great interest in its breeding. According to the FAO data from 2008-2014, the number of these sheep ranges from 500 to 1000. The objective of this study was to determine the phenotypic variability and to assess the external measurements of the Racka sheep. One-hundred fifty Racka breed ewes were included in this study. The effects of three farms on the phenotypic characteristics and their body indexes were calculated. The significance of the research is reflected in the advancement of this breed and in the assessment of the possibilities of selection work in these herds.

The consideration of the descendance is indispensable in the preservation of endangered animal breeds.The authors compared mitochondrial DNA (mtDNA) control region sequence in three descendant breeds of the extinct Zaupel sheep, firstly. Their investigation was carried out in order to prove the common origin of Waldschaf (Austria), Bovec sheep (Slovenia) and Cikta (Hungary).A total of 118 biological samples were taken from non-related representatives of the three breeds between 2015 and 2017. A newly designed primer pair was also used to amplify the segment (1180 bp) to be tested. The total number of haplotypes in the whole study population was 49. The majority of which fell into haplogroup B. The significant negative value of the Fu's Fs statistic (Fs statistic = −3.296, p = 0.013) based on haplotype frequencies demonstrated a moderate foreign gene flow. As a novel observation haplogroups C and D appeared in Cikta and Bovec sheep, respectively. The Tajima D-test value in the entire study population was −0.914 (p > 0.10), meaning that the separation of the three descendant breeds did not cause genetic drift, these are collectively in genetic equilibrium.The genetic information confirmed the common origin of the breeds known from the breed history.
