Abstract

A genetic characterization of goats based on visible polymorphisms and on the calculation of primacy indices was conducted from August to September 2013 on a sample of 101 farms, (relatively similar production conditions) each with at least 06 animals with different phenotypes and at least 2 origins of animal acquisition were sampled for a total of 249 goats (168 females, 49 males and 32 castrated) taken from traditional farms in the agroecological zone of the Guinean High Savannahs of Cameroon. The main results show that: almost all goats have horns with the exception of one motte goat probably because of its young age. The color is mostly brown and all pigmentary patterns identified in the goat species are present with a predominance of five types: illegible, eumelanic, chamois, eumelanic and light belly and phaeomelanic. The type of eumelanin is mostly illegible. The facial profile is mostly concavilinear (95%), the horns dominated by those of straight types are in most cases oriented backwards (72.30%), the tassels are rare (3.61%); The ears are erect (79.9%), semi-drooping (6%) or drooping (6.6%). Frosting is rare as well as variegation. The prime ratings are 0.84 and 0.84 respectively for the segregated loci primarity index (IPs) and the locus agouti primarity index (IPa). The polynomial regression equation (Live Weight (PV) = 56.13-1.71PT +0.018PT2) better predicts live weight with R2 = 0.77. Principal component analysis shows that the cumulative variances of the first two components (weight and body length) explain 65.07% of the genetic variability within the local goat population. These results confirm the degree of belonging of goat populations or breeds to the primary population category (initially traditional population) and the possibility of using selection as a means of genetic improvement.
