Purpose of estrus synchronization

  • Group females for parturition:

a) decrease labor, decrease calving period

b) reduce calving season

c) More uniform weaning weights.

  • Reduce or eliminate estrus detection.
  • Needed for artificial insemination

 

Cattle

  • Prostaglandins – Regression of CL

o Lutalyse, estrumate

  • Progestins – Prevents estrus and ovulation

o CIDR, MGA

o Combined with prostaglandins

  • GnRH – Ovulation, terminate follicular wave

o Combined with prostaglandins in Ovsynch
