THE BREEDING OF VARIOUS PERFORMANCE TYPES OF CATTLE IN IDENTICAL TECHNOLOGICAL CONDITIONS
The work assess the effect of the quality of rearing on milk production of a herd of Holstein (H) and Czech Pied (C) cattle. An evaluation was made of the impact of selected factors (breed, lactation sequence, age at first mating, live weight at the ages of 3, 6, 9, 12 and 15 months) on indices of m...

| description | The work assess the effect of the quality of rearing on milk production of a herd of Holstein (H) and Czech Pied (C) cattle. An evaluation was made of the impact of selected factors (breed, lactation sequence, age at first mating, live weight at the ages of 3, 6, 9, 12 and 15 months) on indices of milk production and reproduction (quantity of milk and contents of the milk components, age at first calving, length of calving interval, insemination index). We measured 8 bodily dimensions to characterize the growth of calves-heifers (height at withers, height at sacrum, direct body length, chest circumference, length of pelvis, front, middle and rear width of the pelvis). The results were evaluated statistically using a linear model in SAS software, with a correlation analysis for evaluating dependencies between the individual bodily measures. The work included monitoring the behaviour of dairy Holstein and Czech Pied cows. In the course of ethological monitoring the dairy cows were found to behave calmly, without manifestations of aggressiveness while maintaining stereotypical behaviour. The chosen technology of housing and treating the dairy cows of both performance types (open cubicle-type stable) can be considered appropriate based on ethological observations. |
