THE RELATION BETWEEN CONCENTRATIONS OF PROGESTERONE, ESTRADIOL AND OVULATION AFTER PGF2α INJECTION AT VARIED DAY OF AFTER OVULATION IN SHIBA-GOAT

摘要：

There are several systems available to dairy producers to help improve heat detection rate or the number of cows submitted for breeding at the proper number of days after calving.Some systems termed estrous synchronization programs are designed to cause cows to come into heat over a short period of time so they can be inseminated in a timely manner. Heat detection is required for these programs. The newer systems, timed artificial insemination (TAI) or appointment breeding named Ovsynch, are designed both the onset of heat (estrus) and ovulation are induced so cows can be inseminated at a specific time without heat detection.
