Genetics and Breeding

Genetic improvement of fibre-producing animal species has often induced transition from double coated to single coated fleece, accompanied by dramatic changes in skin follicles and hair composition, likely implying variation at multiple loci. Huacaya, the more common fleece phenotype in alpaca (Vicugna pacos), is characterized by a thick dense coat growing perpendicularly from the body, whereas the alternative rare and more prized single-coated Suri phenotype is distinguished by long silky fibre that grows parallel to the body and hangs in separate, distinctive pencil locks. A single-locus genetic model has been proposed for the Suri-Huacaya phenotype, where Huacaya is recessive. more »

Although a suri looks very different from the more common huacaya, the conformational traits to look out for are generally the same. The animal should be well proportioned, have straight legs and back, a rounded rump and correct bite. The ears may be slightly longer and the muzzle shorter than a huacaya. more »

The ideal Suri alpaca is the epitome of true alpaca type with a distinctive elegant profile, perfect head, and outstanding conformation. Suri Network members strongly believe that it is important to preserve the purity of the Suri genotype by breeding Suri males to Suri females. The Suri fleece exhibits highly aligned, draping locks of high luster, fine, slick and cool handling fiber. As Suri alpacas approach the ideal state, they express more positive fleece characteristics than less improved types. The concept of the ideal alpaca is not a static model. It is the process of the pursuit of excellence that will fuel genetic improvement for decades. Highly heritable traits are selected for genotypic gain in the individual offspring’s expression of positive breed characteristics, which exist along a continuum. more »
