Conformation scoring data of 1238 beef type Hungarian Simmental cows were evaluated between 2001 and 2011 on the database of Association of Hungarian Simmental Breeders. The aim of the study was to evaluate the effect of sire, herd, birth year and the age at scoring on type score (TIP), height at rump (FMA), width of rump (FSZ), length of rump (FHO), deep of chest (TÖM), length of body (TÖH), muscularity score (IZM), muscularity of shoulder (LIZ), muscularity of thigh (CIZ), conformation of leg (LSZ), side view of hind leg (HLO), gradient of rump (FLE), steepness of pastern (CSÜ), dug score (TGY), deep of dug (TMÉ) and conformation of teats (BIF). The database was analyzed by multifactor analysis of variance. The overall mean of the evaluated ten traits were as follows (mean±SE, point): TIP 5.54±0.04; FMA 5.78±0.07; FSZ 5.25±0.06; FHO 5.33±0.06; TÖM 5.53±0.06; TÖH 5.44±0.05; IZM 4.92±0.06; LIZ 4.83±0.06; CIZ 4.98±0.06; LSZ 5.47±0.03; HLO 5.59±0.05; FLE 5.17±0.05; CSÜ 5.82±0.08; TGY 5.90±0.06; TMÉ 6.27±0.08; BIF 5.34±0.08. The rank in phenotype of the investigated factors was as follows: 1st herd (41.65%), 2nd age at scoring (25.09%), 3rd birth year (15.90%), 4th sire (10.19%), 5th error (7.17%). In the examined period increased the deep of chest, the length of body and the type score. The points of muscularity and dug parameters and the steepness of pastern significantly decreased.
