  Body weight and body linear measurement (Diagonal body length, Height-at-withers, sac pelvic width, Heart girth) of 259 West African Dwarf (WAD) goats (both sexes) in three age groups (Kid, yearling and Adult) were measured. The least square means for body weight were 6.40, 10.5 and 18.9 kg for kid, yearling and Adult respectively. Means of other body linear measurements also vary within each age group. The variables measured vary positively with age of the animals and the correlations of body weight with diagonal body length, Height at whither, sac-pelvic width and heart girth were high, positive and significant (p<0.01). There is sexual dimorphism in body weight and other body linear measurements in favour of the female goats. The correlation matrix of each of the variable or combination could be used in predicting live weight of the animals.

  207 WAD goats were randomly sampled in a survey study of some qualitative traits in Surulere local government of Oyo state, Nigeria. Traits studied were presence or absence of horns (Ho), Wattles (Wa), Beard (Bd); Coat colours and Hair types. Parameters studied revealed sexual dimorphism in the traits studied. Wattles, beard and horns were predominant in both sexes but more prominent in the male goats. The gene frequencies for the recessive alleles beard (0.67) and Horness (1.00) were higher than those of dominant alleles while dominant allele wattled gene (0.68) was more frequent. The majority of the goats sampled had black coat colour (36%) and smooth hair type (84%). The levels of variation in some of the traits surveyed indicated that the WAD goat has not been purified for such traits in the environment; rather their evolvement could be mainly for adaptive purposes.
