Dietary Supplementation with a Probiotic Fermented Four-Herb Combination Enhances Immune Activity in Broiler Chicks and Increases Survivability against Salmonella Gallinarum in Experimentally Infected Broiler Chicks.

The article presents the results of a study on the role of probiotic and herbal diet in enhancing the immunity development in broiler chicks. According to the authors, herbs such as Prunus mume and Curcuma longa and probiotics have immune enhancing and antimicrobial properties. They add that a probiotic fermented four-herb combination (PFH) has a prophylactic effect against Salmonella Gallinarum in a clinical trial of infected broiler chicks.
