Vliv ročního období na projevy chování a parametry mléčné užitkovosti u dojnic holštýnského skotu ve vybraném chovu
Martinková, Petra
In this diploma thesis, the effect of the season on behavioral and milk yield parameters was monitored. The living manifestation included the number of standing and lying cows. Laterality was measured during lying (left and right side preferences). For all dairy cows, the milk yield parameters were also determined: daily milk yield (kg milk), lactation order (n) and lactation phase (days). The observation took place at Farm Hvozdná near Zlín. The subject of the observation was the production stable, where Holstein cattle were housed. The total number of dairy cows surveyed was 2,741 cases. Based on the results, the largest part of standing cows was in Spring (335 cases) and the largest part of lying cows in Autumn (290 cases). The highest average milk yield was found in the summer season (30.2 kg), the smallest in autumn (27.9 kg). This difference in milk yield was statistically significant (p <0.05). The highest milk yield was achieved by cows, which were lying (28.78 kg). The influence of behavior on the order and phase of lactation was statistically significant (p <0.05) in standing cows. It was found that all groups of cows, whether they were divided by season, milk yield, order or phase of lactation, preferred more left side when they were lying. This preference was highly statistically significant (p <0.01).
