Dietary Sodium Diformate Improves Growth Performance and Nutrient Digestibility in Broilers against Negative and Positive Controls
Christian Lückstädt, Stevan Petrovic
Broiler growth rate and feed efficiency are key to economic performance through to market. Dietary formic acid and its salts act against pathogens, helping to decrease pressure on the immune system and improving nutrient digestibility. Previous studies on the antimicrobial impact of organic acids and their salts, including sodium diformate (Formi NDF, ADDCON), placed less emphasis on the impact in the GI-tract of birds. This formed the impetus for this study, which assessed the impact of the additive on pH-levels at different locations of the GI-tract and digestibility parameters. In a trial conducted at a research farm in Iran, 0.1% NDF was tested in a typical corn-soy diet, against both a negative (NC) and positive control (PC) containing an antibiotic growth promoter (500 mg Trimethoprim‒Sulfadiazine per kg). 216 day-old broiler chicks (male Ross 308) were randomly selected into 3 treatment groups with 6 replicates of 12 birds each. Feed, in mash form, and water were available ad libitum throughout the 42-day trial period. The effects of dietary NDF on performance (body weight gain BWG, FCR, broiler index EBI), pH in the gizzard and ileum, Protein Efficiency Ratio (PER) and apparent ileal digestibility of protein and minerals were examined at the end of the trial. Data were analysed using the t-test and a confidence level of 95% defined for these analyses.
