Reproductive Behavior’s: Audiovisual detection of oestrus after synchronization using Prostaglandin F2 Alpha (PGF2α)

Artificial insemination program to increase production is affected by oestrus. Breeders generally identify cows in oestrus based on their behavior. Currently, can be predicted and scheduled due PGF2α synchronization. This study aims determine the detection of after synchronization, more specifically distinguish audio-visual The six used were synchronized using PGF2α. Descriptive methods include (mean, standard deviation). Test. Chi-square was for qualitative data comparison. observed variables onset lust behavior (looking at audiovisual characteristics, video Audio Spectrum Monitor (ASM) application. results showed that response appeared 30 hours synchronization 5 cows. visual appears a lot Mounting activity, Mucus Exit, Vulva Swelling, Restlessness Vocalization duration. ASM recordings show frequency are between 405 Hz -485 injection. In conclusion, shows state oestrus, ready artificial insemination.
