Studies have found that cultures that inhibit salmonella in poultry are inhibited.

Studies have found that competitive rejection cultures (CEs) obtained through good hygiene practices can control salmonella in poultry.
study found that injecting broilers with a dose of the culture on the day they hatched could fight salmonella.
Mead Model Analysis Study explores the ability of competitive rejection culture products Broilact and two probiotics (FloraMax B-11 and Colostity) to prevent salmonella from colonization in newly hatched chicks, using a slightly modified Mead analysis model.
team, led by Carita Schneitz of the Department of Agricultural Sciences at the University of Helsinki in Finland, conducted two experiments.
the first experiment, the chickens hatched on the same day were given a competitive rejection culture and the preparation was treated three times.
second experiment, which included only Broilact and FloraMax-B11, fed probiotics through drinking water to broilers that hatched for three days.
two experiments, two-day-old broilers were poisoned with infant typhoid salmonella.
results show that Broilact is superior to the other two treatments in preventing salmonella from proliferating in newly hatched chicks.
Based on the study, scientists concluded that Broilact was the only treatment that was found in newly hatched chicks, and that its appearance inhibited the proliferation of salmonella, the Journal of Poultry Applied Research reported.
