Feed Additives and Implant Strategies

  1. 1. Breanne Ilse<br />Livestock Research Specialist<br />Carrington Research Extension Center - NDSU<br />Implants & Feed Additives<br />
  2. 2. Implants & Feed Additives<br />Implants<br />Types<br />Effects<br />Methods<br />Feed additives<br />Conventional<br />Natural<br />
  3. 3. Implants<br />
  4. 4. Types of Implants<br />Estrogen based<br />Estradiol 17-ß<br />Progesterone<br />Androgen based<br />Trenbolone Acetate (TBA)<br />Testosterone <br />Combination<br />Androgen/Estrogen<br />(TBA/E2)<br />
  5. 5. Estrogenic <br />(Ralgro, Synovex-C, Magnum)<br /> Metabolically enhance nutrient use to enhance growth<br />Implant Information<br />
  6. 6. Estrogenic Mode of Action<br />Increased<br />Somatotropin & IGF-1<br />ADG and HCW<br />Little change<br />Fat distribution<br />Protein deposition<br />Feed efficiency 5-10%<br />Daily gain 5-15%<br />
  7. 7. Androgenic<br /> (Finaplix-S/H)<br />Tissue building<br />Enhance muscle growth<br />Implant Information<br />
  8. 8. Androgenic Mode of Action<br />Increased <br />IGF-1<br />ADG and feed efficiency<br />No change in intake<br />Feed efficiency 2-3% additional<br />Daily gain 3-5% additional<br />
  9. 9. Combination TBA/E2 <br /> (SynovexChoice,Revalo IS/IH, Synovex Plus)<br />Tissue building<br />Enhance muscle growth<br />Additive effect with estrogenic<br />Implant Information<br />
