One of the big- gest challenges for the poultry industry, par- ticularly after the removal of in-feed antibiot- ics, is bacterial enteritis.


(1 ppm), and fumonisins B1 and B2 produced by Fusarium moniliforme (100 ppm). Aflatoxin B1 accounted for 93.8% of the aflatoxin added to the treatment diets and fumonisin B1 made up 95.8% of the cultured fumonisins added. Broilers fed Calibrin-Z were numerically the most feed-effi- cient group and had the greatest numerical weight gain in all groups fed a mycotoxin-contaminated diet. Broilers fed Calibrin-Z were also statistically more feed-efficient and sta- tistically gained more weight compared to the yeast cell wall-based and algae-based products (Figure 1).


Safe and reliable Performance and efficacy are important when deciding to in- corporate a new feed additive into a ration but safety and re-


liability also need to be considered. Very few companies can say they own the clay mineral that goes into their feed addi- tives, or that they control production all the way from the mine to the feed. Vertical integration with Oil-Dri means Am- lan controls every step of the production process to deliver safe and reliable, high-quality mineral-based products that are also processed in a sustainable manner. In the poultry in- dustry’s search for alternatives to antibiotics, Calibrin-Z can improve poultry intestinal health by binding a broad spec- trum of microbial toxins, thereby helping to control some of the most economically-significant challenges the industry currently faces.
