Název v původním jazyce
The effect of the calving season on the Wood's model parameters and characteristics of the lactation curve in Czech Fleckvieh cows
Popis výsledku v původním jazyce
The aim of this study was to determine the effect of a calving season on the Wood's model parameters of the lactation curve and its characteristics in Czech Fleckvieh cows. The observed Czech Fleckvieh cows (with minimum 75% of CF breed in the genotype)born in 1994-2007 formed three parity groups: parity 1 - 350853 cows, parity 2 - 269276 cows and parity 3 - 175029 cows. All the parity groups were further classified by the calving season: winter (December-February), spring (March -- May), summer (June-August) and autumn (September-November). The Wood's function parameters (a, b, c) were calculated and the lactation characteristics estimated: partial milk yields per 1-100 days, 100-200 days and a total milk yield 305-d, the peak yield -- amount and day, IP (index of persistency) 2:1 and a coefficient of the declination rate of the lactation curve. The calving season significantly affected the parameters (a, b, c) of the lactation curve, the persistency of lactation and the number of da
