Efficacy of Toxfin in Mitigating Mycotoxin Effects in Laying Hens

Year: 2026

Type: article

Abstract: This study evaluated the effects of supplementation with Toxfin™ Dry, a mineral adsorbent composed of bentonite and sepiolite, on productive performance, egg quality, intestinal morphometry, serum biochemical parameters, antioxidant status, and sphingolipid metabolism of laying hens challenged with T-2 toxin and fumonisin. A total of 480 Hy-Line W-36 laying hens at 25 weeks of age were distributed in a completely randomized design with six treatments and eight replicates of 10 birds each, over 112 days divided into four 28-day cycles. Treatments consisted of a control diet, either uncontaminated or contaminated with 2 mg/kg T-2 toxin and 60 mg/kg fumonisin B1, with or without 1 kg/ton Toxfin™ Dry. Mycotoxin challenge reduced egg production (p < 0.0001), egg weight (p < 0.0001), egg mass (p < 0.0001), feed intake (p < 0.0001), eggshell strength (p < 0.0001) and thickness (p < 0.0001), Haugh unit (p < 0.0001), and villus ratio (p < 0.0001), while increasing inflammatory and hepatic biomarkers, malondialdehyde levels, and the sphinganine ratio, with more pronounced effects under combined contamination. Supplementation with Toxfin™ Dry mitigated most adverse effects, with responses approaching those of the control group. The adsorbent reduces intestinal mycotoxin bioavailability and helps maintain performance and physiological homeostasis in laying hens.
