Summary
Three typical types of barn gutter were chosen to clarify the effects of the structure of the gutters on cleanliness of udders and time required for manure handling and udder preparation of dairy cows. Three types of barn gutter were installed to stanchion stalls successively on an experimental basis.HomePage
The three types were; urine-feces mixed type gutter with no cover (A), urine-feces mixed type gutter with steel slotted cover (B) and urine-feces separated type gutter with wood strip cover (C).
Three milking cows (Holstein) were confined in the stanchion stalls installed with one of those three type gutters during 96 hours, and milking and the other routine were conducted by the same workers.
It was found that type B was most reasonable construction compared with the other two types, because cows confined in the stalls with gutter of type B required less time for manure handling and udder preparation, and degree in contamination of udder washed water and dry matter content of dirt come from the udder were less than those of cows confined in the other two types of gutter.
