Keeping feeding equipment clean
Yet another calf scours case today. All equipment for mixing and feeding milk replacer has a visible biofilm. Nearly all the calves are receiving some kind of treatment for diarrhea by the time they are 7 to 10 days old.
No rinsing of equipment before going into the lukewarm wash water. Only household dishwash detergent used to wash with no brushing - only a sponge used to wipe easily accessible surfaces. Bottles and tube feeder left in sink to dry; washed buckets stacked inside each other.
If the deficiencies in the cleaning procedures do not jump out at you in the description above try reviewing these resources:
Equipment cleaning checklist - an explanation of the rinse:wash:rinse:dry procedure
Equipment cleaning protocol - English a one-page protocol that can be laminated and posted at a cleaning station (i.e., sink in utility room).
Equipment cleaning protocol - Spanish same protocol as above in Spanish
Equipment cleaning protocol - French same protocol as above in French
P.S. Yes, I did recommend culturing samples of "as-fed" colostrum, "as-fed" milk replacer and taking blood samples from calves 1-7 days old for blood serum total protein testing.
