Vliv doby dojení na intenzitu zalehávání boxově ustájených dojnic
Dosedlová, Jitka
The aim of this thesis was to analyze the influence of milking period on the inten-sity of lying behaviour of dairy cows kept in boxes. An ethological observation was carried out at the agricultural company GenAgro Říčany corp. on the breeding of Czech fleckvieh cattle. I mainly observed the intensity of the average time of lying in a boxing bed after dairy cows arrival from a milking house, depending on milking time. I have elaborated a literature review and also worked out a methodology on this issue. I have found out that the intensity and the time of lying were above all influenced by seasons and the age, or rather by the order of lactation of the monitored dairy cows, when the longest time to lie took dairy cows during the first lactation. The biggest number of dairy cows lying was during warm months ( July, 122 pcs ), but in a longer interval ( May, 43.6 minutes ) than cows during cold months ( November, 87 pcs ) when more dairy cows were lying, but faster ( November, 32.9 minutes). The fastest cows were lying into the row 1, closest to the feed table, at the average time of 37.8 minutes and most slowly to the row 3, closest to peripheral walls, 42.2 minutes on average. The influence of a particular lactation stage was very slight, the dairy cows above 301 days of lactation lay a little faster ( 38.0 minutes ) in comparison to the ones up to 100 days ( 39.1 minutes ).

Odpočinkové chování dojnic českého strakatého plemene ve vztahu k použité podlahovině boxu
Dosedlová, Jitka
In my thesis I was to analyse Czech Fleckvieh dairy cows resting behaviour in relation to flooring in stall. I focused primarily on bedding height preferences and also on prefe-rence of cubicle row in a barn. Influence of products that reduce bedding moisture was monitored as well. I observed the influence during the month. Literary review concer-ning this issue was created and it was supplemented by observations. Observations took place in agricultural company Genagro Říčany, a.s. I had been found that dairy cows prefer stalls with 9--10 cm high bedding, in which they lied down 131,7--142,4 min. after coming from milking parlor. Line preference in barn has been also observed, line closest to the trough was preferred. In both observations diary cows lied down in 137,9--135,9 min. Last observation was to compare treated and untreated bedding. More dairy cows lied down in the group where moisture reducing product was used but it took them a longer period of time.
