  1. Implants and Additives Galen Erickson

  2. Partially missing implant • Improper Location • Crushed Implants Implanting Defects

  3. Abscess • Walled-off Implanting Defects

  4. Implants and Body Composition • Implants increase protein deposition. • Implants cause a upward shift in the growth curve. • The shift in the growth curve influences body composition at a given weight.

  5. Implants Change the Growth Curve 28.6% EBF Low Choice

  6. Relationship of empty body fat to Quality Grade(total of 1,355 animals)

  16. Rumensin Large Impact on Nutritional Management • ↓ Performance • ↑ Intake Variation • ↑ Acidosis • ↑ Digestive Deads • ↓ Coccidiosis Protection Cooper slides, 2004

  19. Rumensin Performance Four Trial Summary (2,904 Steers) Source: Laudert, 1990 Cooper slides, 2004

  20. Rumensin Performance • Original research showed 10% improvement in feed conversion • Recent research shows 3-4% improvement • Difference likely due to ration energy level • Summary • Direct effect on performance is lower in today’s rations • Greater improvement with Deads-In Cooper slides, 2004

  21. Rumensin Digestive Deads • Dr. Baxter Black, 1980 • Digestive deaths decreased by 2/3rds after inclusion of Rumensin Cooper slides, 2004

  22. Rumensin Digestive Deads Cooper slides, 2004

  23. Rumensin Acidosis Rumensin reduces acidosis and bloat • Directly • ↓ lactate production • ↑ lactate utilization • ↓ rumen fluid viscosity • Indirectly • ↓ day-to-day intake variation • Improved feeding behavior Cooper slides, 2004

  29. Rumensin conclusions Acidosis and Bloat • Feed more roughage • Level • Type • Limit extensively processed grains • High moisture corn • Steam-flaked corn • Optimize byproduct level • Digestible fiber replacing starch • Corn oil increases energy content • Provides small amount of lactate Cooper slides, 2004

  30. Ionophore Economics Rumensin improves F:G by 4% 1% change in F:G improves $2.80/hd range $2.50 to $3.00 Therefore: $10.00 to $12.00 return from performance Cost: 2 cent/hd/d: approximately $3.00 RUMENSIN SAVE: range: $7.00 to $9.00 1996 Scientific Update, Elanco Animal Health; Laudert, 1990

  33. Tylan Economics none Tylan %change F:G 6.72 6.90 -2.6 1% change in F:G improves $2.80/hd range $2.50 to $3.00 Therefore: $6.50 to $7.80 return from performance Cost: 1 cent/hd/d: approximately $1.50 TYLAN SAVE: range: $5.00 to $6.30

  34. MGA Interaction with heifer age (Mader and Lechtenberg, 2000; Anderson, 1991) 1% change in F:G improves $2.80/hd range $2.50 to $3.00 MGA generally: 4%+ improvement with yearling heifers Therefore: $10.00 to $12.00 return from F:G sell more weight 10 to 15 lb.

  36. Expected Response Steers 100 200 300 Increase in live wt 10 17 21 Increase in carcass wt 6 14 18 Calculated return, $/hd Price at $80/cwt live 6.30 6.60 4.50 Price at $70/cwt live 4.20 4.90 3.50 Steers only, fed 28 days and ~$7.00 for Optaflexx fed at 200 mg/hd Current Elanco recommendation: 200 mg/hd for 28 d.

  37. Optaflexx issues Requirements 70-430 mg/hd/d 8.2 to 24.6 g/ton (90% DM basis) 9.1 to 27.3 g/ton DM At 24 lb DMI = 16.7 g/ton DM Fed final 28-42 days prior to market Recommendation 200 mg/hd/d for 28 days

  38. Optaflexx issues Benefits Increased weight (profitable) Improved efficiency late in feeding period Little to no effect on carcass traits Approved for use with Rum/Tylan

  39. My thoughts Increases Decreases • Weight • N retention late • REA • Efficiency • YG • No effect (<200 mg) • Marbling • Tenderness With trained panels, > 200 mg was not as positive on carcass quality Very positive on most traits, and is safe Concern with sorting and the 28-42 d window, may create challenges Fun to test over the next few years

  40. Zilmax • Zilpaterol hydrochloride • 22.05 lb bag (10kg) • 4.8% product • 4.8% of the bag is active Zilpaterol • 21.77 grams of active/lb (48 g/kg) • One bag contains 480 g of Zilmax • Corn cob grit, Zilpaterol, surfactant and binder • Manufactured in France • Store at or below 77 degrees F

  41. Permitted Claims and Limitations b

  42. Zilmax Inclusion Rate • Cattle Fed in Confinement for Slaughter • All feeding rates on label expressed on a 90% DM basis • 6.8 g/ton on a 90% DM basis • 7.6 g/ton on a 100% DM basis

  43. Zilmax Feeding Directions • Feed continuously to cattle fed in confinement for slaughter as the sole ration for the last 20 to 40 days at 7.6 g/ton (100% DM) to provide 60-90 mg/hd/d. • Approved to be fed in combination with Rumensin, Tylan and MGA • Approved for use in Type B supplements dry (meal or pelleted) and liquid
