  1. aMilo, a draught-tolerant crop also known as grain sorghum, is a food product for humans and livestock feed grain. In the US, the feed grain is mainly for poultry and cattle
  2. bMHA is the calcium salt of 2-hydroxy-4 methylthio butanoic acid (Novus International), providing 84 % methionine activity. MHA inclusion rate was adjusted to reflect methionine activity provided from Zn(HMTBa)2 (80 % methionine activity) and Zn-MET (20 % methionine activity) to maintain an equal methionine level across all treatments
  3. cThe mineral premix provided in the final diet (mg/kg): 60 Mn (MnO); 80 Fe (FeSO4 · 7H2O); 8 Cu (CuSO4 · 5H2O); 0.35 I (ED Iodide); 0.15 Se (NaSeO3). Analyzed final basal diet Zn was 8.5 mg/kg
  4. dVitamin premix provided in the final diet (mg/kg): retinylacetate 10; cholecalciferol 6.25; dl-alpha tocopheryl acetate 90; menadione sodium bisulphate 7; calcium pantothenate 10; cyanocobalamin, 1.4; riboflavin 6.5; niacin 37; biotin 0.15, thiamin monoitrate 2.25; pyridoxine 4.25; and folic acid 0.9
  5. eSilica was removed from the diet as different Zn sources were added
