Counteracting Fusarium proliferatum toxicity in broiler chicks by supplementing drinking water with Poultry Aid Plus.

To test whether Poultry Aid Plus (PAP, a commercial product for drinking water application) could reduce the stress on broiler chicks caused by Fusarium proliferatum contamination of feed, water (with or without PAP application, according to the manufacturer's instructions), and feed (experimentally infected with F. proliferatum fermented and dried corn culture material, CM) were provided to broiler chicks for 3 wk. Eight treatments consisting of a 2 (with or without PAP in water) x 4 (0, 1, 2, and 4% CM in feed) factorial design were tested in four replicate cages of six chicks each. The diet with 2% CM reduced weight gain by 23%; this reduction was preventable by PAP water application. The diet with 4% CM caused a cumulative mortality of 87.5%, which was reduced by PAP water application to 50%. The population half-life of the chicks on the diet with 4% CM was 6.5 d; this half-life was prolonged to at least 21 d by PAP water application. The PAP application also reduced the relative weight of the small intestine and promoted Lactobacillus colonization of the large intestine regardless of the level of CM in feed. Therefore, water application of PAP can be a prophylactic measure for F. proliferatum toxicity in poultry production.
