Rozdíly v odpočinkovém chování na pastvě a ve stáji u krav bez tržní produkce mléka ve vybraném chovu
Ostrý, Tomáš
The aim of this bachelor´s thesis was comparing differences in relaxing behaviour of suckler cows at grazing and in the stable. This relaxing behaviour included frequency of standing and lying. For lying cows there was explored the preference of right or left side and the head´s orientation to cardinal points. The observation took place at Ostry´s farm in Kozlov by Bystřice nad Pernštejnem during one year between December 2015 and November 2016. By one day in month in time from 7 a.m. to 7 p.m. there were observed suckler cows, mostly crossbreeds of beef breeds. Finally, was evaluated 1391 cases. There are some results at comparison of the differences in relaxing behaviour of cows in depending on technology. Cows in wintering place stood more than on grazing (p < 0,05), but the part of lying cows was almost identical in both places, in stable and on grazing (p > 0,05). Next results are at evaluation of temperature influence. Cows with high statistical significance (p < 0,01) stood more by lower temperatures (to 5 °C), than by higher temperature (15,1 < °C). The part of lying cows with statistical significance was higher in temperature zone 15,1 < °C, than in temperature zone to 5 °C and in zone between 5,1 and 15 °C. Cows in the zone 15,1 < °C preferred left side and cows in zone to 5 °C and zone between 5,1 and 15 °C preferred right side. This result is without statistical significance. By evaluation influence of relative air humidity found out followings. Cows with high statistical significance and with growing relative air humidity more stood, and they devoted to other activity less. The part of lying cows was almost identical in all humidity zones. Lying cows on grazing had head oriented mostly to west, alternatively to north-west or to south. This result has high statistical significance. Lying cows in wintering place had head oriented mostly to east, alternatively to north or south. It has high statistical significance, too. By other categories (heifers and calfs) in depending on technology there was not detected statistically significant difference in relaxing behaviour besides laterality. The heifers preferred right side more on grazing than in stable with statistical significance. Calfs preferred right side on grazing and left side in wintering place.

Vliv možnosti výběhu na frekvenci životních projevů dojených krav
Fikejsová, Romana
The objective of this thesis was to compare differences in relaxing behaviour in the stable and grazing land of milk-producing cows. The rest behaviour of cows included the frequency of their standing and lying, while the lying cows were further examined for its laterality, which is the preference of the right or left side. The observations were carried out during one year in July and November 2018. The observations took place in a large capacity cowshed in the village of Jenišovice. Milk-producing cows, the breed of Czech spotted cattle, were observed at rows number 4 and 8 for 10 days each month, 11 observations were made every day, altogether 110 observations were carried out throughout the whole observation period. When we compare relaxing behaviour overal we find that more cows prefer standing, both in the stable and outside, by 28% compared to lying cows. When comparing laterality it was found that cows are by 6% more on the right side. In both the first and the second observation the cows are more in the stable box, by 50% more than out of the box where is 25% out of the total number of cows.

Vlivy působící na odpočinkové chování krav plemene charolais na pastvě ve vybraném chovu
Kuráňová, Martina
The aim of this study was to determine how resting behavior is affected by time of day, temperature and seasons in cattle at the pasture. The experiment took place from spring to autumn, on a farm in the village of Bystřice and its surroundings. The herd was always monitored for 10h and individual expressions of life were recorded every 15 min. At the same time, temperature was measured in the interval of 30 minutes. With Charolais cattle were monitored frequencies of lying/standing and preferential behavior of cattle while resting such as preference of left or right side of the body and the choice between sunny or shady place for lying/standing. Time of day especially had an influence on the choice between lying in the sun or shade. Animals during the morning hours prefer lying in the sun, after 13 h herd opted shadow. Regarding temperature, there was mainly influenced preferential behavior, in terms of choosing a place to rest. With increasing temperature, animals statistically significantly preferred a shady place to lie down. On the contrary, it was evident that at colder temperatures animals liked to lying down on the sun. The ratio of lying and standing animals was slightly influenced by temperature and animals were mostly lying more than standing. Seasons influenced both the selection of places to rest as well as the ratio of standing and lying animals. Bigger amount of the animals were recorded standing at spring. In contrast, in the summer and fall, herd was lying more often. In spring and autumn, animals preferred lying in the sun and in the summer herd preferred lying down in the shade. There were also monitored other vital signs, such as movement, food intake, water intake, urination and defecation, comfortable and social behavior.
