Across
  1. 2. Fescue toxicosis.
  2. 4. Imbalance of ________ (grass tetany, milk fever).
  3. 6. High N + K has no effect on [Mg], but _________ bioavailability (absorption by animal).
  4. 12. Drought and frost stress disrupt protein synthesis, excess N stored is dhurrin.
  5. 14. Used for releasing gas during bloat.
  6. 16. Factors affecting [dhurrin].
  7. 17. Inhibitors of digestion.
  8. 18. High K fertility ________ [Mg] because of preferential uptake of K in grasses.
  9. 20. Factors affecting [dhurrin].
  10. 22. _________ types - clovers: berseem, arrowleaf; lespedezas, birdsfoot trefoil, sainfoin.
Down
  1. 1. NO3-, HCN, ergovaline, dicoumaro.
  2. 3. Antifoaming agent, a nonionic surfactant.
  3. 5. _________ acid - hydrocyanic acid, HCN, found with drought, frost.
  4. 7. Supplement with Mg, Ca, and ________.
  5. 8. NO3 (forage) -> NO2 (rumen)-> NO2 (hemoglobin) prevents O2 uptake from lungs, blood is blue.
  6. 9. Grass Tetany, low magnesium concentration in the blood.
  7. 10. Concentration decreases with age, proportionately less immature tissue in the plant.
  8. 11. Nitrogen fertilization _________ [Mg] in forage when soil Mg is adequate.
  9. 13. Leaves > stems; upper > lower. Immature tissues have highest concentrations.
  10. 15. Bloating traps _________ gases (CO2, CH4) by preventing eructation.
  11. 19. Factors affecting plant _______ concentration: High nitrate uptake from N fertilizer, time, plant part - stem > leaves; opposite of HCN.
  12. 21. - Rumen wall expands and cuts blood supply to lungs.
