An intravaginal progestrone release insert for controlled breeding in cattle.

Expand All
  • Approved uses / Indications

    For the control of the oestrus cycle in maiden heifers and parous cows to enable synchronisation for concentrated artificial insemination (AI) or embryo collection and transfer programmes. Treatment of post-partum and suckling anovulatory anoestrum (non-cycling) cows.

  • Key Features

    Recent trial work1 shows early treatment with CIDR brings forward the conception date of the CIDR group by 10-16 days. This means 10-16 more days in milk per CIDR cow.

    Progesterone suppresses oestrus and ovulation in cycling animals and primes the hypothalamo-pituitary axis in non-cycling (anoestrus) animals. Removal of the insert and the subsequent fall in progesterone level allows a surge in LH pulse frequency, follicle maturation and a predictable oestrus and ovulation to occur.

  • Packaging

    Each pack contains 10 inserts. Each insert contains 1.38g progesterone in an inert silicone elastomer. Store at room temperature. Keep out of reach of children.

    Day -2

    Remove CIDR Cattle Insert and inject LUTALYSE (A3231) prostaglandin (with maiden heifers only a half dose is required).

    Day 0

    Mate to observed heat

    Day +1

    Inject unmated cows with GnRH (e.g. 8 μg buserelin or 100 μg gonadorelin) and perform fixed time AI at same time.

    For administration directions refer to label.

  • Precautions
