Zusammenfassung:Unsatisfactory reproductive performance in dairy cows has been associated with environmental influences, such as season, chronic and acute changes in dietary intake and body composition. These factors can affect fertility especially ovarian function and yield and quality of oocytes and embryos. In our study the cow ´s body condition affected the overall embryo recovery rate (proportion of collected embryos to palpated corpora lutea). The significantly higher number of embryos was collected from cows with BCS 2.5- 2.75 (68.32 % embryo recovery rate) and 3.0- 3.25 (63.30 %) compared to the cows with BCS 2.0-2.25 (53.33%) and 3.5-4.0 (47.87%; P
