The objective of the study was to detect the difference of the conformation scores between dams and daughters in Latvian Warmblood horse breed. For this purpose the correlations and regression coefficient between conformation traits of broodmares and the same traits of their daughters were estimated. Data of Latvian Warmblood horse breed broodmares were analyzed. The horse breeding organisations’ evaluating data from 1995 till 2015 were analyzed. The data included conformation valuation of Latvian Warmblood horse breed dams (n = 423) and their daughters (n = 596) of different ages. An average in ten-point scale in the group of dams was 7.71 ± 0.04 for top line scoring, 7.33 ± 0.05 for forelimbs and 7.35 ± 0.05 points for hind limbs. An average of valuation points of their daughters was 7.51 ± 0.03 for top line scoring, 7.21 ± 0.04 for forelimbs and 7.21 ± 0.04 for hind limbs. A significant difference between valuations of dams and their daughters (p0.05) was found for all three conformation traits. Positive and low correlation was calculated between groups of dams and daughters for all three conformation traits. The results show that the relationship between conformation traits of dams and daughters was weak. Further studies are needed in order to estimate influence of broodmare quality to daughters, analyzing the latest data of progeny.
