From: Ingestion of Lactobacillus rhamnosus modulates chronic stress-induced feather pecking in chickens
Expression of severe and gentle feather pecking behavior. Frequency of severe (a) and gentle (b) feather pecks per minute (Least Squares Means ± Standard Error) between weeks 24 and 26 based on supplementation (Lacto: L. rhamnosus, Placebo: Placebo supplementation) and stress (S: stressed, NS: non-stressed) treatment (n: S-Placebo = 22, NS-Placebo = 22, S-Lacto = 20, NS-Lacto = 22). Asterisks (*) indicate statistically significant differences (P < 0.05).
