Summary
The construction and operation of slatted floor in a free stall dairy barn have been studied in order to obtain basic data for designing slatted floors. The results are as follows. The mean setting space of slats was 45.2mm. Feces remained on the slats decreased as cow density increased. Eight cases of foot rot or contution were observed for the first year of the operation. The slatted floor system was found to be a labor-saving system. Only 20% of average time for getting rid of feces from general Japanese barns was spent in this barn.HomePage
