The objective of this study was to compare stall status and cow preference (lying in or occupying
stall) by barn side for factors affecting stall use. A closed circuit television system monitored and
recorded stall use in a 4-row, 104-stall freestall barn at, 2 p.m., 8 p.m., 4 a.m., and 9 a.m., each
day, from 5/9/01 to 2/9/02. Eight factors were analyzed: stall base (BASE), time of day (TIME),
stocking density (SRATE), distance to water (WDIST), stall location within stall base section
(SLOC: END vs. NOTEND), stall location within barn (RLOC: INTR (not wall side) vs. EXTR
(wall side)), inside barn temperature (TEMP), and length of time cows exposed to stall bases
(XPOSR). Two barn sides were analyzed: low stocking density (LowSD, 66%), with cows milked
by robotic milker, and high stocking density (100%SD), with cows milked 2X in parlor. Six
BASEs were tested: mattresses (MATR1, MATR2), waterbed (WATR), soft rubber mat (SRMAT),
concrete (CONC), and sand (SAND). The SAND based stalls were not tested on LowSD. The
BASEs were grouped 3 to 7 stalls/section and randomly placed in each row.
