Determination of estrus duration based on cervical mucus characteristics in Aceh cattle using camera-equipped artificial insemination endoscope

This study aimed to determine the length of estrus period in Aceh cows based on changes characteristics cervical mucus observed using a camera-equipped artificial insemination (AI) endoscope. used twelve healthy and reproductively sound aged 4-6 years. All were synchronized prostaglandin F2α (PGF2α) injected intramuscularly twice, 11 days apart. Estrus detection was conducted 24 hours following second injection PGF2α three times daily for 30 minutes, respectively. Estrous then subjected examination their at 0, 6, 12, 18 after beginning estrus. showed that out 12 samples, only eight exhibited signs. Characteristics 0 6 transparent. At estrus, five transparency, remaining cloudy mucus. Meanwhile, all sampled regarded as end That means this 15.75 ± 3.11 hours. It can be concluded determination duration carried an AI endoscope with camera. For further research, it is suggested apply technique implementation pregnancy rate.
