*5.2.1 Prostaglandin treatment*

Luteolytic agent such as prostaglandin F2α, or an analogue, which causes the regression of the corpus luteum can be used to synchronize estrus [30, 31]. Administration of PGF2α is only effective from 8 to 17 days of the estrous cycle when functional corpus luteum is available in one of the ovaries. Fertility is high after prostaglandin synchronization. Synchronization of estrus and fertility with this product are good in cyclic females but not in non-cycling cows.
