This paper deals with evaluating in 2 stables the exploitation of lying cubicles for housing dairy cows littered with separated slurry. There were 86 lying cubicles evaluated in the stable V and 87 lying cubicles in the stable T. In both stables, cows were milked in the morning and in the evening, separated by an approximate interval of 12 hours. The exploitation of lying cubicles was evaluated on the basis of monitoring daily behaviour of cows by identical researchers who performed a direct observation at an interval of 10 minutes. The following behaviour was observed: normal lying with cow's head situated near the brisket locator (L), contrary lying with cow's head situated near the rear curb (Lo), standing with 2 front legs in the lying cubicle (Sf), and standing with 4 legs in the lying cubicle (S). Furthermore, lying in alleys (La), standing in alleys (Sa), movement in alleys (M), feeding (F) and drinking (D) were also evaluated. In the stable V, cows were lying in cubicles in their natural position (L) 33.13% of the time out of the 12 hour daily observation (it was 31.08% for the stable T). The total time which cows spent in cubicles by lying or standing (L + Lo + Sf + S) was 40.98% in the stable V and 56.86% in the stable T. In the stable T, cows used to lie down into wet alleys 5 times more frequently than in the stable V, and the total time of lying in individual cubicles was significantly affected by direct solar radiation not accepted by animals.
