Popis výsledku v původním jazyce

In years 1997 - 2000 we evaluated body condition in the set of 1086 heads of HF cows and primipars. Body condition was evaluated in insemination time. Cows milk production in kg in day of insemination, development of sexual organs at AI time, season, year, environment and body temperature at AI time were used like further classificatory effects. All factors were reached for reproduction results of this cows. Results of AI was evaluated with sonograph investigation of gravidity between 30. - 45. day after AI. We used GLM method of SAS/STAT 6.12 for own analysis. Average of overal herd conception was 36,12% after all inseminations, 26,36% of cows was determined like non-pregnant and in 5,58% was detected ovarian cysts. Body condition was evaluated in cows from 1,5 to 5 points and body condition average of herd was 2,86. Daily milk production were in evaluated cows on level 28,15 kg. We determined significant differences in reproduction results in relation to body condition (P Ł 0,05). Lo
