Conteúdo: 	This study used data registered inthe Brazilian Pantaneiro Horse Association, in the period
of 1972 to 2000. Fifteen linear biometric measures taken at registration (Wither height, ba-
ck height, croup height, midback height, head lenght, neck lenght, back-loin lenght, 
croup lenght, shoulder bone lenght, head width, chest width, hip width, shin bone perime-
ter and thorax perimeter), on 2248 registered animals were analyzed using the 
MTDFREML program to estimate genetic and phenotypic variances as well as hertabilities
genetic and phenotypic correlation between the traits of interest. The factors sex, month,
year of register and age were fitted as fixed effects in the model. In general the coefficient
of variation for these traits was low (2 to 8 percent) which may indicate selection problems
in the future. The heritabilities evaluated lay between 0.27 (head width) and 0.83 (thorax perimeter). The inbreeding coefficient was in general low with a mean level of 8 percent,
for the animals that showed inbreeding (1 percent). The genetic correlations were high 
between all 15 linear biometric measures, except for traits that correlation with the thorax
perimeter that were low and sometimes negative.
