Dietary sodium diformate improves productivity index in broilers under tropical conditions

Gastrointestinal health remains a primary hurdle for commercial poultry success, traditionally managed through prophylactic antibiotics. however, shifting regulatory landscapes and consumer demands are driving the search for reliable alternatives. In the study "Dietary sodium diformate improves productivity index in broilers under tropical conditions," researchers Christian Lückstädt, Stevan Petrović, and Prasad Kulkarni from ADDCON, Germany, presented at the Tropentag 2025 conference, evaluate how organic acid salts can bridge this gap. The research specifically examined the impact of 0.15% sodium diformate (NDF) against both negative controls and diets containing Oxytetracycline in a 35-day trial involving 250 birds in South Asia.

The practical value for producers is found in the significant boost to the European Broiler Index (EBI), which integrates average daily gain, survival rates, and feed conversion. While the performance of the antibiotic-treated group and the negative control remained statistically similar, the birds supplemented with sodium diformate achieved an EBI of 398—a notable 8.9% increase over the control groups. For professionals managing operations in heat-stressed or tropical environments, this suggests that NDF does more than just replace antibiotics; it optimizes overall biological efficiency. From an academic perspective, the study raises an interesting point regarding the limitations of traditional AGPs in certain environments, as the sodium diformate significantly outperformed the antibiotic-enhanced diet, suggesting a more robust mode of action in stabilizing the gastrointestinal environment under tropical pressures.

Given that sodium diformate outperformed traditional antibiotic growth promoters in this trial, do you believe we are reaching a point where organic acids are no longer just "alternatives" but actually the superior choice for performance in tropical climates?
