Salmonella Enteritidis (SE) is a persistent challenge in poultry operations. We have been adding our BioProbiotic to the feed of poultry for many years as a way to eliminate this pathogen in the gut. However, we recently had some new operations take things in a different direction that we had not considered before. These operators had just recently introduced BioProbiotics into their poultry feed. Not all flocks had access to it yet, and some flocks were at the end of their production period. In between flocks, after cleaning out one of the barns, they had the obligatory swab test for SE. The test came back positive. They decided that instead of using a harsh chemical disinfectant, they would simply spray the physical surfaces of the barn (floor and some walls) with a diluted mixture of our BioProbiotic. Eight days later, a second swab test came back clean - No SE!
Below is the farmer's report in his own words, showing the formulations he used and when.
"My depop swabs were positive for SE. I depoped March 30. I have a scraper system, so I did not remove slats to clean out. I cleaned out litter, scraped all the floor and slat surfaces to get chunks off, and blew the whole inside of the chicken house down. Still had some litter chunks in my slat holes. But as a whole, it was pretty clean.
I sprayed Bio-Probiotics on Tuesday, 4-14. I sprayed it with a backpack mister blower. I sprayed a total of 24 gallons. I sprayed 9 gallons straight. 15 gallons of it I mixed 2 gallons of water and 1.5 gallons of product. So that was a total of 24 gallons of product and 20 gallons of water. So the total liquid volume was 44 gallons.
A week later, late evening of Tuesday, 4-21, I sprayed 15 more gallons of product mixed with 22 gallons of water. So the total liquid was 37 gallons.
Both times, the scratch area and slats were wet. I got some on the walls, but not wet like the floor surfaces."
Swabs were taken again on Wednesday, 4-22, a day after the second application. On Monday, 4-27, my swabs came back negative for SE.
I did not wash down or use any disinfectants.
The reason I applied the 2nd time was my service tech didn't come to swab till eight days after the first application, so I decided to reapply just in case for some reason SE got tracked back in the chicken house during those eight days."
