In my work I deal with analysis of the impact of selected parameters of the breeding environment to live weight of cows. Observations took place in the company Golden Farm Ltd. in the village Štětovice with 60 pieces of Czech Pied breed. Among the parameters ana-lyzed were breeding environment milk yields, order and stage of lactation. Attention was dowry-Vána stage of pregnancy and the effect of the calendar month of the year on the live weight of cows. Data were collected during one year starting from September 2014 to October 2015. The obtained results were obvious influences lactation and gestation stage on live weight of cows. Cows at first lactation during gestation had lower weight (713 kg) than on the fifth (816 kg). Furthermore, it was found to influence calendar months of the year. Here, the weight varied depending on the season. Effect of milk production on a live weight of cows, but not conclusively confirmed, although cows with higher average milk yield of 25 l have a higher body weight (749 kg) than cows with milk yield up to 20 liters (703 kg).
