Using a proven broiler model to differentiate mineral bioavailability of GemStone™ OTM from inorganic sources GemStone Organic Trace Mineral (OTM) Vs. Inorganic Standard Minerals

Outline Introduction Experiment 1 Experiment 2 Experiment 1b Objective & Procedures Results Relative Biological Value Experiment 2 Experiment 1b Experiment 3 Summary

Introduction Young broiler chicks are typically used to determine trace mineral availability and requirements great sensitivity of young, rapidly-growing animals Tests to determine the relative bioavailability of trace minerals must be conducted at low (< 30 ppm) trace mineral basal levels that result in a significant response of the test materials relative to the basal diet Relative Biological Value (RBV) - relative to trace mineral sulfate standard. Prophylactic trace mineral levels, above normal premix and dietary levels, are typically fed to commercial birds test model of 49 day-old market age broilers essential to determine therapeutic value of zinc and manganese levels

Experiment 1 Objectives Procedures Determine zinc availability of GemStone OTM compared to zinc oxide and zinc sulfate in broiler chickens Procedures Ross 708 male broiler chicks reared in battery brooders, with raised wire floors. Supplemental Zn provided at 10, 20, 30, & 40 ppm above basal Zn (23.3 ppm) 8 birds/cage; 10 cages/treatment Broilers fed a semi-purified, low-Zn ration from 0 – 7 days of age (Zn depletion) Birds fed test diets from 8 – 21 days of age Live performance measured Tissue zinc determined (AHPharma, 2014-1)

Zn Oxide (Negative Control) Zn Sulfate GemStone OTM Treatments Zn Oxide (Negative Control) Zn Sulfate GemStone OTM 1 Using Zn from each Zn source, added Zn replaced cornstarch and was adjusted to contain either 10, 20 or 30 added Zn levels. 2 Zinc Sulfate served as both standard and Positive Control and was added at the rate of 10, 20, 30 and 40 ppm Zn. 3 Negative Control (no ppm Zn added) served as Negative Control. 4 Basal ration (without added Zn levels) contained 23.3 ppm Zn. (AHPharma, 2014-1)
