Synchronization of estrus and fertility in Zebu beef heifers treated with three estrus synchronization protocols

open access: yesTheriogenology, 1999
The effects on estrus and fertility of 3 estrus synchronization protocols were studied in Brahman beef heifers. In Treatment 1 (PGF protocol; n=234), heifers received 7.5 mg, i.m. prostianol on Day 0 and were inseminated after observed estrus until Day 5.
