Live weight and 21 body measurements of 110 Thoroughbred, 75 Gidran, 109 Nonius, 97 Hungarian Sport Horse, 172 Hungarian Cold Blooded Horse and 20 Murinsulaner type adult brood mares in 28 studs were evaluated in Hungary. One way ANOVA was used to compare the genotypes. Some body measure indices were determined. Phenotypic correlation coefficients between the live weight and body measurements were estimated. Regression equations were developed to estimate the live weight from body measurements. Significant differences were found between the live weight and 21 body measurements of different genotypes. The rank of the investigated genotypes according to live weight was as follows: Hungarian Cold Blooded Horse (742.1 kg), Murinsulaner type (649.3 kg), Nonius (614.9 kg), Hungarian Sport Horse (600.9 kg), Gidran (563.4 kg) and Thoroughbred (542.0 kg). The results of girth measurements for the warm blooded breeds were similar to the data found in the literature. Considerable difference was found between the genotypes in body measure indices. The absolute and relative body size values prove clearly and objectively, that there are significant differences in the conformation of Thoroughbred, Gidran, Nonius, Hungarian Sport Horse, Hungarian Cold Blooded Horse and Murinsulaner type adult brood mares. The most close relationship with the live weight (r=0.89-0.92; P<0.01) was shown the body condition and nutritional status related measurements (heart girth, 2nd width of rump). For the estimation of live weight with regression model the necessary data are as follows: hearth girth, 2nd width of rump and length of body (R2=0.91; P<0.01).
