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.
