Abstract

A study was carried out to investigate the morphological and biochemical characteristics of local pig populations in three agro-ecological areas of Cameroon from June to September 2018. Morphological and morphometric parameters were measured in 300 pigs (147 males and 153 females) aged 6 to 8 months old. Phenotype characterization of local pigs showed diversity as follows: concave head profile, black coat colour type, plain coat colour pattern, prick ear type, projecting upwards, a long and thin snout type and straight tail. Analysis of variance showed that all quantitative parameters measured in the pigs of the three agro-ecological zones were considered. Comparisons between sexes also revealed differences in some features in some regions. The growth-related parameters were strongly correlated, case of Heart Girth and Head Length, Body Length, Height Withers, Wither Hock, Tail Length, Live Weight; Body Length and Wither Hock, Live Weight; Live Weight and Wither Hock. Local pigs from the bimodal rainfall, Sudano-Sahelian and highland areas of Cameroon showed a great morphological and biochemical diversity; those from the highland are better discriminated from those of the Sudano-Sahelian and bimodal rainfall areas. The cluster analysis of biochemical and morphological features could be congruent, confirming the differentiation of highland pigs from the pigs of the other two agro-ecological zones.
