Estrus Synchronization

Estrus management in dairy cows is necessary to achieve predictable breeding and calving seasons.

Objectives:

  • To obtain a calving interval as close to 365 days as possibleright arrowSpontaneous occurrence and/or induction of estrus and insemination of the maximum number of cows as soon as possible postpartum.
  • Maximize milk productionright arrowInduction of estrus and insemination of the maximum number of cows as soon as possible postpartum.
  • Planning of lactation in the herd according to particular market demands (favorable price, seasonal products, etc.)right arrowSynchronization of estrus and breeding of groups of cows.
  • Reduce labor expensesright arrowInduction and synchronization of estrus for fixed time insemination. Reduces or eliminates the need for labor for estrus detection.
  • Management of embryo donors and recipients in embryo transfer programs.
Pharmacological estrus management can be used as therapeutic measure in cases of:
  • Postpartum anestrus
  • Cystic Ovarian Disease
  • Persistent corpus luteum

In cattle with active ovaries, the estrus cycle can be manipulated through:

  1. Prostaglandins
  2. Combination of prostaglandins and GnRH (OvSynch protocol and modifications)
  3. Progestagens (progesterone and progestagens)

In dairy herds with high incidence of ovarian inactivity the following systems are recommended:

  1. OvSynch protocol and modifications
  2. Progestagens (progesterone and progestagens)
