Ractopamine is a beta-adrenergic agonist that increases leanness and carcass weight in finishing pigs. Our previous study observed that dietary ractopamine increased the abundance of several glycolytic enzymes in the sarcoplasmic proteome of post-rigor pork longissimus thoracis muscle. Pork semimembranosus…

Effects of ractopamine and gender on protein turnover in skeletal muscle of implanted steers and heifers

  • 2011
  • Issue: 1
  • Volume: 41
D.K. Walker, E.C. Titgemeyer, D.E. Johnson, S.B. Laudert & B.J. Johnson Page: 16 - 23

Effects of the β-agonist, ractopamine-HCl (ractopamine), on skeletal muscle protein turnover were evaluated in 16 steers (512 kg) and 16 heifers (473 kg).  Treatments were arranged in a 2 × 2 factorial design and included gender (steer vs. heifer) and…
