- •
Evaluated incorporation of FSH in an estrous synchronization protocol for TAI.
- •
Incorporation of FSH did not affect TAI or overall pregnancy rates of cows or heifers.
- •
Cows expressing estrus before AI had a greater TAI pregnancy rate.
- •
The TAI pregnancy rate in heifers was similar, regardless of estrous response before AI.
