| Description
| - The aim of this study was to evaluate the influence of sire, body condition score (BCS and body weight (BW) changes on reproduction in dairy cows.The cows were divided into groups according to their sires and the lenght of service period in particular groups was compared. No significant influence of sire on the lenght of service pariod was found. BCS was observed once a month, BW every day with using of tenzometric scales. Significant diferences were found in BCS in 1st, 2nd and 3rd months of lactation. The highest BCS was in 1st month (in average 2,7 points), the lowest in 2nd month (2,27 points). The highest BW was in 1st month of lactation (554,12 kg), the lowest in 2nd month (538,31 kg). The correlation coeficient between BCS and BW changes was found highly significant 0,38. The correlation coeficients between BCS nad BW and lenght of service period were found highly significant (0,49 and 0,37). The correlation coeficient between BW and calving to first heat was found highly significant 0,39.

- Cílem studií bylo stanovit vliv býka, změn kondičního skóre (BCS) a tělesné hmotnosti (BW) na reprodukci dojených krav. Krávy byly rozděleny do skupin podle otců a délky servis periody. Byl zjištěn nevýznamný vliv otců na délku servis periody. Kondiční skóre bylo sledováno jednou měsíčně, tělesná hmotnost každý den tenzometrickými vahami. Významný rozdíl byl vysledován u kondice v 1., 3. a 3. měsíci laktace. Nejvyšší kondiční skóre bylo v 1. měsíci (v průměru 2,7 bodů), nejnižší ve 2. měsíci (2,27 bodů). Nejvyšší živá hmotnost byla zjištěny v 1. měsíci laktace (554,12 kg), nejnižší ve 2. měsíci (538,31 kg). Korelační koeficient (0,38) mezi kondicí a živou hmotností byl vysoce průkazný. Korelační koeficienty mezi změnami kondice a živé hmotnosti a délkou servis periody byly také vysoce průkazné (0,49 a 0,37). Vysoce průkazný byl také korelační koeficient mezi tělesnou hmotností a otelením k první říji (0,39). (cs)
