Název v původním jazyce

Milk yield during the first lactation and its relationship with the productivity in consecutive lactations of Montbeliarde cows in the Czech Republic

Popis výsledku v původním jazyce

The observation was carried out on a group of 917 cows of the Monbeliarde cattle in Czech Republic. All cows finished the first three lactations. The total mean milk yield was 4 509.9 kg (first lactation), 5 383.1 kg (second lactation) and 5 767.5 kg ofmilk (third lactation). The relationships between the lactations were described by individual estimation coefficients that were calculated as a ratio of milk yield in subsequent lactation to milk yield in preceding lactation. The mean estimation coefficient between the first lactation and second lactation was 1.218, between the first and third lactation 1.314 and between the second and third lactation 1.095. Estimation coefficients between all lactations decreased significantly with increasing milk yield in the first lactation. Estimation coefficients between the first and third lactation increased significantly with the increasing estimation coefficients between the first and second lactation while the coefficients between the second a
