Study on the relationship between body weight and linear measurements of West African Dwarf (WAD) goats as influenced by sex and agro-vegetational zone was carried out using 200 animals comprising 100 goats each of both sexes. Animals were measured in two different zones where they are reared extensively and kept as security against crop failure and supply of animal protein. Analyzed results indicated significant (P<0.01) phenotypic correlations between body weight and morphometric traits, and this cut across both sexes and zones. The study also revealed high positive significant (P<0.01) phenotypic correlations between morphometric traits regardless of sex and zone where the animals are found. Of all body linear measurements, heart girth was closely related to body weight, that is, recorded highest correlation coefficient value with body weight, while height-at-withers has the least relationship, that is, lowest phenotypic correlations with body weight. The study also indicated sexual dimorphism as regards the relationship between body weight and linear measurements. It was also discovered that relationship between body weight and morphometrical traits in WAD goats differed from one zone to another. Therefore, it is suggested that measurements on animals to be used for breeding or commercial purposes should be sex and zone restricted.
