Description
| - In this thesis we dealt with effect of age at first calving on milk production of Czech Fleckvieh at first and second lactation. We analyzed set of about 5 000 pieces of animals from our prominent breeding of Czech Fleckvieh. We evaluate dairy cows, which calve from 26th to 36th month of their life. Next criterion of choice was the length of both first and second lactation, which should be at least 280 days. These criteria fulfil overall 3 155 dairy cows. Their milk yield per lactation was converted to milk yield per day. Regarding the 1st lactation the highest milk yield per day was set in group of dairy cows, which calved in 36th month of age (23.57 kg of milk per day), and the lowest dairy milk yield in group calved in 32nd month of age (21.51 kg of milk per day). If we focus on the milk yield in the 2nd lactation, we will find out, that the highest milk yield reached dairy cows, which calved in 27th month (25.87 kg of milk per day) and the lowest milk yield reached dairy cows, which calved in 35th month (22.64 kg of milk per day). We can thus state, that milk yield in 1st lactation of dairy cows calved sooner is average, but in the 2nd lactation the yield was higher
