Abstract
In order to evaluate the effects of acidifiers and essential oils in drinking water on growth, intestinal digestive capacity, and immune status in broilers, a total of 480, 1-day-old Arbore Acres broilers were randomly assigned to four treatments including normal tap water (Ctr) and tap water supplemented with acidifier I (ACI), acidifier I and essential oils (ACI+EO), and acidifier II (ACII). Both ACI+EO and ACII increased final body weight. The pH value of the crop and gizzards was reduced by ACI+EO, and ACII decreased the pH values of the proventriculus and gizzards (p < 0.05). Compared with control group, ACI, ACI+EO, ACII significantly enhanced lipase activity in jejunum but ACII decreased the level of serum total cholesterol and total triglyceride (p < 0.05). Compared with the control group, ACI+EO and ACII significantly increased the relative weight of the spleen, increased the level of serum IgA and IgM, and decreased E. coli in excreta, while ACII significantly decreased Salmonella in excreta (p <0.05). All treatments significantly increased Lactobacillus in excreta. In conclusion, ACI+EO improved immune status and ACII was effective in reducing Salmonella and promoting Lactobacillus, contributing to intestinal health.
