Synovex® H Heifer Growth and Finishing Implants

Expand All
  • Each implant of eight pellets contains oestradiol benzoate 20 mg, testosterone propionate 200 mg.

  • Improved weight gain in heifers older than 6 weeks of age.

    Oestradiol is thought to increase the amount of circulating growth hormone through its action on the hypothalamus and pituitary. It also increases amounts of circulating insulin and thyroxine, leading to an increase in protein synthesis, nitrogen retention, blood glucose and metabolic rate. The result is an increase in muscle tissue. Testosterone has a direct effect on muscle tissue, displacing glucocorticoids and slowing the rate of muscle breakdown.

    Maximum growth rate requires good quality stock with adequate control of parasites and other diseases, and good quality feed through pasture, supplements or lot feeding. Growth response may vary widely for nutritional or other reasons.

  • Promotion of weight gain in heifers more than 6 weeks old; for use during the growing or finishing phase.

  • Do not implant in any other site or in any other species of animal than described in the product label. Do not implant into HPG free accredited cattle or implant sooner than 70 days after the last implant.

  • Implant only as per label directions.

    Animals implanted with this product must be individually identified with an approved ear punch mark. Never sacrifice careful, clean technique for speed of implantation. Crushing or breaking of pellets may result in bulling. Implanting cattle under 6 weeks of age is not recommended. Implanting animals intended for breeding is not recommended as they may experience decreased fertility.

  • Vaginal and rectal prolapse, increased bulling activity, high tailheads, sunken loins, ventral oedema and udder development may occur as side effects of treatment. To help avoid abscess formation at the site of implant, the surface of the ear should be thoroughly cleaned and disinfected before implantation.

  • If poisoning occurs, contact a doctor or Poisons Information Centre.
