Angora Goat and Billy-Goat in Brazil

Angora Goat and Billy-Goat  belonging to species

                    Capra hircus ( Capra hircus aegragus).

 The Angora goat can be confused with sheep, his extrordinary wool that covers the entire body except face and legs.
Almost all Angora goats in Turkey are silvery-banking, but there are variations: brown, gray and black are created in Siirt and Mardu. Race known since 2400 BC, originating in Angora, Anatolia, Asia Minor, a region of poor soils and highly variable temperature.

 Currently created mainly in Turkey, Soviet Union, South of África and United States.

                                              In Brazil
The Angora goats herds found and raised here in Rio Grande do Sul allegedly were developed from the originated Turkey race introduced for over a century.

 At first, many brazilian states bought angora, especially Rio Grande do Sul. In 1907 Rio Grande do Sul had 53.762 goat's head, in 1916, 121.128 a select flock was created.  

But currently goat's flock are uncommom in Brazil and objects of genetic research. Recent genetics studies point the possibility of a new goat race naturalized.

Some genetic 
After at least thirty years without records introduction of pure race animals or crossing with others, selective pressure manegement and environment, it is belived that these individuals have diferent phenotypic characteristics from initial race.
The objective is to estimate the genetic variability using a mitochondrial's fragment DNA (MINA) and (mt DNA) in four goat populations. 
The sample analysed so far (n=25) is composed of individuals from the districts of Canguçu (9), Bagé (9), Santana do Livramento (4), Alegrete (3).

Are being analyzed fragments of 701 pairs base of mt DNA control region using primers obtained from literature, HVR1 forward reverse.
For data analyses, the Chroma Clustal X 1.6 ( sequence alignment), DNA SP4 ( characterization of haplotypes) and Mega 2 ( phylogenetic) programs ( sequence edition) will be used.
