Implication

Changeover trial reveals that calcium benzoate and organic acids enhance nutrient digestibility and lower urinary pH in swine, suggesting potential reductions in manure ammonia emissions.

Key Points

To determine the effects of dietary calcium benzoate and organic acids on dietary buffering capacity, nutrient digestibility, nutrient retention, and urinary excretion characteristics in growing swine.
Eight ileal-cannulated barrows (initial body weight 30 kg) were evaluated in a 2 × 4 factorial cyclic (8 × 5) changeover design.
Diets based on tapioca, corn, and soybean meal were formulated with or without 2.4% calcium benzoate across four organic acid additions (none, formic, fumaric, or n-butyric acid at 300 mEq/kg feed).
Calcium benzoate decreased dietary buffering capacity by 54 mEq/kg feed, increased ileal digestibility of dry matter, organic matter, and specific amino acids by up to 2.4 percentage units (P < .05), and decreased urinary pH by 1.6 units (P < .001).
Total tract digestibility of dry matter, ash, calcium, and gross energy, as well as calcium retention, increased with calcium benzoate (P < .05), whereas nitrogen retention was unaffected.
Organic acids, particularly formic and n-butyric acids, improved ileal digestibility of most amino acids (P < .05) and increased total tract digestibility of dry matter, crude protein, phosphorus, and retention of nitrogen and calcium (P < .05).
