Faktory ovlivňující výběr boxu dojnicemi českého strakatého plemene skotu

The objective of the dissertation thesis was to analyse factors affecting preference of cubicle of Czech Fleckvieh dairy cows. Monitoring was carried in farm GenAgro Ricany a. s., a period of 12 months (June 2011 -- May 2012). The objective of monitoring was one section - one quarter of stable (n = 98 cows). Total of 47 040 observations were analysed. Statistical evaluation of data was performed by STATISTICA 10.0. In the sectionwas comprised of 103 comfortable stalls (cubicles) distributed into 3 rows.. Row A -- closest to feeding table (32 cubicles); row B -- in the midle section (33 cubicles); row C -- close to the side wall (38 cubicles). In all factors (number and stage of lactation, milk yield, number of arrival from milking parlour, temperature and humidity in stable and THI, height in the cross) was found significantly influence (p < 0,01) on preference of cubicle row. In evaluation of preference of boxes it was found out, that the lowest occupation rate in whole observing was in those boxes, which are on the edge of rows. Also lower amount of visits was noted in boxes, which are surrounded from more than one side by wooden partition separating space for lying (box) from waterhole. On the contrary mostly occupied boxes were those, which are located in the middle of box rows. Further higher preference rate of left side when lying was found in all observed influences, identically at both outer rows. On the contrary dairy cows preferred right side when lying in middle row.
