How is estrus synchronized for timed artificial insemination?

At NCSU, Boer does that had kidded at least once before were assigned to either traditional estrus synchronization with AI following heat checking (Heat Check) using the AM-PM rule (if in estrus AM, breed PM, and vice versa) or the ovulation synchronization method with timed artificial insemination (NC Synch).

How is estrus synchronization used in cattle breeding?

Estrus synchronization combined with artificial insemination (AI) is used regularly in cattle and has been useful for breeding management. These technologies would also be useful for goat farmers interested in using AI to increase the genetic merit of offspring.

Why is it important to use estrus synchronization?

Estrus synchronization optimizes labor and time, and improves the ease of using artificial insemination (AI) (Lamb et al., 2009). Use of AI allows access to superior genetics, accelerates genetic change within a herd, and is frequently less expensive than natural service (Johnson and Jones, 2004).

How long does it take to synchronize estrus with natural service?

Based on our current knowledge, if long-term progestin-based protocols are used for synchronizing estrus with natural service, making sure that a window of 16 to 19 days passes prior to the administration of PGF is imperative to ensure adequate fertility.

Why is it important to synchronize estrus in mares?

Synchronizing estrus in mares is necessary or at least highly advantageous in a variety of breeding management circumstances, including shipped cool or frozen semen breedings, scheduling around stallion availability, delaying the first postpartum ovulation, and embryo or gamete transfers, to name a few.
