Which of the following is/are induced (reflexive) ovulators?

Correct Answer: All the above (Camel, Cat, Rabbit)

Induced (reflexive) ovulators are species in which ovulation is triggered by the mechanical stimulus of mating (coitus), not by an endogenous LH surge tied to a fixed cycle.

Induced vs Spontaneous Ovulators

• Induced ovulators: Ovulation ONLY occurs after mating stimulus → LH surge triggered by coital stimulation → ovulation follows in 24–36 hours. Examples: Camel, Cat, Rabbit, Ferret, Mink, Llama
• Spontaneous ovulators: Ovulation occurs automatically during estrus regardless of mating. Examples: Cattle, Buffalo, Mare, Sheep, Goat, Sow, Bitch

Significance for AI in Induced Ovulators

• In induced ovulators, AI or hormonal injection (hCG/GnRH) must be used to trigger ovulation since natural mating is not occurring.
• In camel AI programs, ovulation is induced with GnRH or hCG at the time of insemination.

Memory Tip

'Camels, Cats, and Rabbits need a trigger (CCR — must be Coitally Cued for Reproduction)'
