“…This could have a significant impact on the rural economy of particular geographic areas with protected status. The Girgentana is an endangered goat breed from Sicily (Italy) and has semi-protected status [48,49]. A panel of 20 microsatellite markers were used on Girgentana, Maltese, and Derivata di Siria goats and eight microsatellite markers alleles were present in Maltese and Derivata di Siria goats but absent in Girgentana goats.…”

Goats ( Capra hircus ) were domesticated during the late Neolithic, approximately 10,500 years ago, and humans exerted minor selection pressure until fairly recently. Probably the largest genetic change occurring over the millennia happened via natural selection and random genetic drift, the latter causing genes to be fixed in small and isolated populations. Recent human-influenced genetic changes have occurred through biometrics and genomics. For the most part, biometrics has concentrated upon the refining of estimates of heritabilities and genetic correlations. Heritabilities are instrumental in the calculation of estimated breeding values and genetic correlations are necessary in the construction of selection indices that account for changes in multiple traits under selection at one time. Early genomic studies focused upon microsatellite markers, which are short tandem repeats of nucleic acids and which are detected using polymerase chain reaction primers flanking the microsatellite. Microsatellite markers have been very important in parentage verification, which can impact genetic progress. Additionally, microsatellite markers have been a useful tool in assessing genetic diversity between and among breeds, which is important in the conservation of minor breeds. Single nucleotide polymorphisms are a new genomic tool that have refined classical BLUP methodology (biometric) to provide more accurate genomic estimated breeding values, provided a large reference population is available.

The Bulgarian Screw-horned longhaired goat is a local breed, distributed in the mountainous regions of Bulgaria. The largest compact herds with preserved breed type of the animals are differentiated into two main habitats. I. The region of Southwestern Bulgaria - mainly in the southern and western border mountains of the Blagoevgrad region (the slopes of Southern Pirin, Slavyanka, Ograzhden, Malashevska mountains). II. The region of Western Stara Planina (settlements along the northern slopes) - mainly the Vratsa and Teteven regions. Exactly from these two areas (Teteven region and settlements in the border regions of Blagoevgrad region) in the 1968 year Professor Altman selects animals for conservation work with this breed in the GDR (1). Initial monitoring of the population shows some variation in the exterior signs of specimens in the two native distribution areas. This requires a detailed study and comparative analysis of the exterior in specimens from the respective areas. For the purposes of the study, complete measurements and descriptions of the exterior were performed in 50 goats and 20 bucks, respectively, from each areal. The Bulgarian Screw-horned longhaired goat from the area of Northwestern Stara Planina was larger and more massive than the animals from the area of Southwestern Bulgaria. The heigh at withers for the goats from the Vratsa region was 74.42 cm and 66.06 cm in goats from the Sandanski region. This sign in the bucks also shows a difference of almost 10 cm - 83.75 and 72.45, respectively for male animals from the two regions. The differences were proven with a high degree of probability. The goats from the area of Northwestern Stara Planina has a longer and broader head, the ears were proven to be longer, than in the animals from Southwestern Bulgaria. The horns of both male and female specimens from the Vratsa region were extremely rough and massive. The differences were proven with a high degree of probability.
