Etologie prasat při pastevním způsobu chovu
NOVÁKOVÁ, Kateřina
The aim of the work was to register the elementary behaviour of pigs in extensive farming under different climatic conditions (in June, September and February). The herd consists of 41 Mangalica pigs 30 sows, 10 piglets and 1 boar. The interval method was used for the observation and the herd was observed for 24 hours during each interval.

Vliv klimatických podmínek na chování ovcí
BLEHOVÁ, Zuzana
The objective of this thesis was to record the basic categories of behaviour of the sheep breed Suffolk under different climatic conditions throughout the year. The flock of meat sheep breed was grazed with the possibility of entry into the stables. Monitored were the basic categories of behaviour: movement, standing, lying down, feed intake. Comfortable behaviour, sexual behaviour, maternal behaviour, and water intake were monitored by frequency method. Four monitoring were carried out in total by interval method (interval length 10 min) for 24 h during the year (spring, summer, autumn and winter). Monitored was 68 pcs sheep of the basic herd and 3 breeding rams. In all observations the most represented categories were feed intake and lying. The longest feed intake period of sheep was in the winter 47.5 % of day at very low temperatures i.e. up to 10 °C. On the contrary, in the summer, at very high temperatures, sheep favoured the laying of 50 % per the day. In contrast the shortest time was dedicated to standing and movement. The shortest period of standing was recorded in the summer, when sheep stood 5.8 % of the day, and the shortest period of movement was recorded in the fall with the representation of 9.2 %. Climatic conditions greatly influence the grazing regime of sheep. Among the factors that disrupt the daily routine of the animals belonged heavy rain, thunderstorm, and high temperatures.

Vliv klimatických podmínek na chování koz
MOJŽÍŠKOVÁ, Nikola
The aim was to record the basic categories of behavior of milked goats on an organic farm with regard to the different climatic conditions throughout the year. The herd of approximately 100 goats for milk production was kept throughout the year with unlimited access to pasture freely within the enclosure. Followed the basic categories of behavior: feed intake, exercise, lying and standing. There were five investigations done by interval method (interval of 10 minutes) after 24 hours at different macro climatic conditions (rain, mild winter, frost, heat, optimum temperature). In all investigations were the most represented category relaxing form of lying. The goats rested longest at low temperatures approximately (-12C) for 42% of the day. In contrast the shortest duration of resting during high summer temperatures approximately (32C) was 35% of the day. The length of feed intake was relatively stable with the longest intake in winter by up to 10% to 25% of the day. Climatic conditions affect the regime of the day, especially in determining the time of intake. Goats grazed in summer when high temperatures mostly in the early morning, while the optimal temperatures were grazing evenly distributed throughout the day. Goats are very active, which is due to their lively temperament. Increased unrest in the herd was recorded in relentless rain.

Ethology of water buffalo (Bubalus bubalis)
NOVÁKOVÁ, Ivana
Breeding of water buffalo (Bubalus bubalis) began to expand throughout the world from the centre of the buffalo domestication - India in the last years, especially because of their hard working, flexibility and resistance to disease. Buffaloes are currently more kept in farm condition especially for the production of milk and meat. Because of buffaloes are often kept in condition developed for cattle, reproductive efficient is reduced and displaying of social and maternal behaviour is often unnatural. The aim of study is focused on ethology of water buffaloes kept in semi- natural conditions in zoological garden Dvorec. The findings can contribute to the creation of better conditions for these animals, which are kept on farms and thereby improve their overall performance.

Ethological manifestations sheep along pastoral season
KOUTNÁ, Zdeňka
The aim of the thesis is to write down and evaluate the base categories of the sheep grazing behaviour during one grazing period as regards the various climatic conditions. The method of the direct observation was used when the length of interval was 10 minutes. It was done five times for always 24 hours during a grazing period. The longest time of the grazing (43,8 % of the day) was found out in July. High temperatures shortened the time of the grazing to 26,8 % of the day. If the growth is of poor quality the time of the movement is lengthened out to 10 % of the day. The longest time of the lying category was found out in August (54,4 % of the day).
