Analýza pohybového skóre dojnic českého strakatého skotu ve vztahu k technologii ustájení
Fadrný, Petr
The aim of this diploma thesis was to analyze movement score of the Czech Fleckvieh Breed dairy cows in relation to housing technology. Practical part was performed in selected companies ZePo, a.s. Libchavy and ZD Mostek with different housing technologies. The observation took place from January to December 2017. The cow's movement score was determined when returning from the milking parlor. Motion score 1 - healthy cows, motion score 2 to 5 - cows with varying degrees of locomotor disorders. Milk productivity parameters included: Milk (kg milk), lactation phase (s), lactation order (n), fat (%) and protein content (%). Based on the results, we can see that the housing technology affects the movement score (P < 0.01). In addition, we can observe that the movement score affects the decrease of the amount of milk, especially at the 4 and 5 movement scores (P <0.01), and also leads to the increase in protein and fat content (P <0.05). Thus, we can say that housing technology has an impact on the dairy cow movement score and, therefore, on dairy cows yield. Poor technology reduces milk yield by 2 kg per cow per day. Keywords: technology, milk performance, milk yield, dairy cow, movement score
