Abstract:

A protocol to make anestrous cows more likely to cycle prior to estrous synchronization would greatly enhance reproductive efficiency. Ease of application, availability, and low cost make feeding melengestrol acetate (MGA) a good choice in such a protocol. MGA, used as a progestin “primer,” has no detrimental effects on cows that are already cycling and reduces the number of cows expressing short cycles.
