Effect of milk urea content on reproduction in postpartal dairy cows

Popis výsledku v původním jazyce

Milk urea concetrations may be used as a diagnistic tool in investigation of reproductive performance in cattle. The aim of this study was to evaluate the effect of milk urea content (MUC) level on the length of insemination interval and service period (SP). The observation took place in the Holstein cows herd from autumn 2004 till summer 2005. The individual milk samples were taken in 30 days interval during the first 5 month of lactation and the MUC was determined. The length of insemination intervaland service period were used as the reproduction indexes. The analysis of variance and correlation and regression analysis were used . The lowest MUC was found in the first month of lactation, from the second month the concentration incerased. The average MUC in first 100 days of lactation was 34,52 mg/100ml, which is above the optimal variation. The correlation coefficient between MUC in the first 100 days of lactation and the lenght of insemination interval and SP were statistically si
