1. Planned production of a number of ova from the one cow at the same ovulation period is an essential part of the technique of bovine embryo transfer. Can be effected with a single injection of PMSG or for better results, with FSH and LH in a 5:1 ratio, twice daily for 5 days. Called also multiple ovulation.
2. Can occur accidentally when cows are treated with large doses of FSH as a treatment for no visible estrus.
