“…The height at the withers was higher in the Maghrebi camel than in the Rendille camel, but smaller than those measured in Mewari, Jaisalmeri and Targui camels (Mehta et al, 2007;Oulad Belkhir et al, 2013). These differences between groups of dromedary in term of body measurements are genetically linked and revealing geographical distribution (Mahrous et al, 2011;Almathen et al, 2012). The height at the hump was low in Maghrebi camels compared to those described for Sahroaui and Targui in Algeria (Oulad Belkhir et al, 2013).…”

Five groups of Maghrebi camels have been identified in southern Tunisia according to their tribal affiliation: the Ourdhaoui Médenine in Tawazins tribe, the Ourdhaoui Tataouine in Oudarna tribe, the Guiloufi in Beni Guilouf tribe from Kébili, the Gueoudi at Ouled Gharib tribe from Kébili and the Merzougui in the Marazigues tribe from Kébili. The identification of these groups was achieved by recording nine body measurements (length of the body, length of the neck, thoracic girth, abdominal circumference, height at the hump, height at the withers, width between shoulders, length of the anterior limb and the length of the tool) from a total of 304 female camels (age ≥ 6 years). Positive correlation was observed between the height at the hump and height at the withers, the thoracic girth and the abdominal circumference, the length of the body and the length of the neck. However, the length of the tail showed a negative correlation with the abdominal circumference and the height at the withers. Gueoudi, Guiloufi and Merzougui camel groups had the higher body length and the higher abdominal circumference compared to Ourdhaoui Médenine group of camels. Accordingly, Guiloufi, Merzougui and Ourdhaoui Tataouine camel groups had the higher thoracic girth and the higher height at the withers in comparison with Ourdhaoui Médenine. Ourdhaoui Médenine and Ourdhaoui Tataouine camel groups had the higher tail length compared to Gueoudi, Guiloufi and Merzougui camel groups. The clustering of the five groups allowed describing three main classes of Maghrebi camel including the big, medium and small size Maghrebi camels. According to the coat color, six vernacular names were identified included Chagra, Chaâla, Safra, Hajla, Hamra and Zarga. The quality of the hair was on majority rough and thick, that way the female camel was named Nagga Chalfi. One small proportion was attributed for the females that had sleek and heavy hair which were named Nagga Khawar.

Kafkas Univ Vet Fak Derg, 23 (3): 467-471, 2017467-471, . DOI: 10.9775/kvfd.2016 AbstractMicrosatellites are a class of genetic markers commonly used for parentage verification and population studies. This study determined the efficiency of microsatellite markers for identification and pedigree analysis in horses based on the example of Turkmen horse population. For this purpose, 748 Turkmen horse samples including 574 adults (92 stallions, 345 males and 137 mares) and 174 foals (98 colts and 76 fillies),were genotyped by using seventeen microsatellite markers recommended by ISAG. The number of allele per locus varied from 5 (HMS01 and HTG07) to 10 (HTG10) with an average value of 7.65. The observed heterozygosity and the expected heterozygosity ranged 0.365-0.953 (mean 0.703), from 0.617-0.884 (mean 0.792) respectively. PIC value ranged from 0.586 (HTG7) to 0.873 (HTG10) with average 0.767. The total exclusion probability of the 17 microsatellite loci was 0.9999. The pedigree study of the Turkmen horse using microsatellite markers was efficient in detecting mistakes during genealogical records. These results suggested that the DNA typing method had high potential for systematic control of the genealogical registrations and genetic resources to improve genetic aspects in Turkmen horses.

“…In previous examinations on the origin and genetic diversity of Middle Eastern and Western Arabian horses, which were based on mitochondrial DNA and DNA microsatellites analyses (Mahrous et al . ; Khanshour & Cothran ), low population differentiation estimates were reported. In the present study, we tested if the designation of three Syrian Arabian horse strains—Saglawi, Kahlawi and Hamdani—is consistent with the origin of the three legendary founders.…”

Genetic diversity of Syrian Arabian horses

Although Arabian horses have been bred in strains for centuries and pedigrees have been recorded in studbooks, to date, little is known about the genetic diversity within and between these strains. In this study, we tested if the three main strains of Syrian Arabian horses descend from three founders as suggested by the studbook. We examined 48 horses representing Saglawi (n = 18), Kahlawi (n = 16) and Hamdani (n = 14) strains using the Equine SNP70K BeadChip. For comparison, an additional 24 Arabian horses from the USA and three Przewalski's horses as an out group were added. Observed heterozygosis (H ) ranged between 0.30 and 0.32, expected heterozygosity (H ) between 0.30 and 0.31 and inbreeding coefficients (F ) between -0.02 and -0.05, indicating high genetic diversity within Syrian strains. Likewise, the genetic differentiation between the three Syrian strains was very low (F < 0.05). Hierarchical clustering showed a clear distinction between Arabian and Przewalski's horses. Among Arabian horses, we found three clusters containing either horses from the USA or horses from Syria or horses from Syria and the USA together. Individuals from the same Syrian Arabian horse strain were spread across different sub-clusters. When analyzing Syrian Arabian horses alone, the best population differentiation was found with three distinct clusters. In contrast to expectations from the studbook, these clusters did not coincide with strain affiliation. Although this finding supports the hypothesis of three founders, the genetic information is not consistent with the currently used strain designation system. The information can be used to reconsider the current breeding practice. Beyond that, Syrian Arabian horses are an important reservoir for genetic diversity.
