Data were available on 1034 animals registered in the genealogical registration book of
the Brazilian Pantaneiro Horse Breeders Association (ABCCP) from 1991 to 2000. Fifteen
linear measures were analyzed using GLM, PRINCOMP and CORR procedures of SAS.
In general, the effect of the factors studied were important (p<0.01) causes of variation
for all the 15 traits except for month of birth that wasn't significant (p>0.05). Sex is signifi-
cant (p<0.01) for most traits. Sex did not affect the back loin length. The factor sub-region
and breeder within sub-region were significant (p<0.01) for all measures, except head 
width, which wasn't significant. This may present a preference for type of animals for bre-
eder within sub-region. Of all the traits, body lenght and chest width were significant (P<0.01) for age. The month of registration wasn't significant for the wither height, croup
height and head width. The year of registration wasn't significant for wither height, back height, croup height, midback height and shin bone perimeter. Of the traits examined the variance coefficients in genral were low. The correlation between heights were in general
high. The correlation between height and others measures were medium, excep for with
body width which was higher (0.52). Body width and the other widths had a tendency to
have higher correlations. The variation must be carefully monitored along with inbreeding
coefficients to ensure that the decrease in variability does not adversely affect the benefi-
cial chracteristics of this breed.
