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

The thesis "The Differences in Cows' Relaxation Behaviour of the Czech Pied Cattle Breed and Selected Charolais Breed" is focused mainly on the period of standing and lie down. As for both breeds' lie down a left and right side preference is studied. Standing is divided according to two aspects -- period of standing and standing-eating. The observation was performed on a farm "ZePo, a.s. Libchavy" in November 2014 and was proceeding in two phases. The observation took place in three stables, specifically in a binding stable for cows of Czech Pied cattle breed, free hutch stables for cows of Charolais breed and free hutch stables for dairy-cows. From the full number of cows, in the stables, the group of 20 cows was selected, with the average milk yield of about 24 kilograms and in 150 lactation days. Among monitored factors influencing the cows' behaviour the following ones were chosen: breed and technology of stabling. Concerning the influence of breed on standing highly significant matches were found (p<0,01) As for the preference of the left side or right side the differences in the Czech Pied cattle were statistically highly significant (p<0,01) and Charolais breed statistically insignificant (p>0, 05). Due to the stabling technology there were not differences in the standing and standing-eating, the result was statistically highly significant (p<0,01). The binding stable indicates the preference for diary-cows to the right side with the high statistical significance (p<0,01). In the free stable cows prefer the left side without statistical significance (p>0,05).
