Individual variations and differences connected with housing or management are known to affect the actual lying. A series of experiments cows kept cubicle houses was carried out. We investi-gated consequences some details house overcrowding on standing cubicles. The aim obtain information about significance cubicles for resting hiding. Four were out total seven different groups cows. In first experiment, so-called old house, which differed various ways from new other three performed. each normal situation — as many feeding places animals group compared an overcrowded both number reduced. four experiments, levels 50, 55, 25 33.3% tested. To measure eating, lying, detailed observations 24-h periods. Under conditions, ∼13 h 2.5 per 24 h. under lower than house. This probably due two factors: (1) smaller less comfortable; (2) could hide confrontations mates at rack its separations between well Overcrowding resulted reduction also reduced It concluded that over-crowded more important Based these available literature, it means cows; however minimum need lie stand not yet known. Various factors suggested may how long lie.
