Abstract

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

Abstract

Accurate determination of estrus status in an animal based on an appropriate estrus detection method can guarantee the cows' pregnancy after mating. This study aims to determine the estrus status of Aceh cows using the van Eerdenburg estrus behavior scoring method. This study was conducted from 22 January to 12 February 2021, at the Technical Implementation Unit for Animals of the Faculty of Veterinary Medicine, Universitas Syiah Kuala, Banda Aceh, Indonesia. The sample used was eleven Aceh cows aged 4-6 years old. Parameters observed were the number of cows exhibiting signs of estrus using the estrus behavior scoring method. The accuracy of estrus detection was confirmed by palpation per rectum to detect the presence of uterine tone. By observing signs of estrus using the method studied, 90.9% (10/11) of the cows were determined to be in estrus. Confirmation by the presence of uterine tone showed a 100% accuracy rate. The most effective sign of estrus was the passivity of the cow when being ridden by another cow or bull. This study concluded that estrus status in local cows could be determined using the estrus behavior scoring of the van Eerdenburg method.

Abstract

Twelve healthy and not pregnant local cows, aged 3-6 years, 1-3 parity. The cows were synchronized using the PGF2α of 5 ml/cow intramuscularly, twice at 11 days intervals. The Estrus detection based on the scoring of van Eerdenburg was conducted 24 hours after the second prostaglandin injection three times daily for three days. The changes in cervical dilatation were observed at 0, 6, and 12 hours from the onset of estrus. The result showed that 8 of 12 cows were estrus after twice PGF2α injection. All the estrus cows showed mild cervical dilatation with liquid and transparent mucus (opening cervix score 1) at 0-hour observation. Six hours later, 62.50% of cows remained at opening cervix score 1, and 37.50% changed to opening cervix score 2 (optimum cervical dilatation with thick and transparent mucus). At 12 hours after the onset of estrus, 25% of estrus cows had cervical closure (opening cervix score 0, closed cervical with thick and turbid mucus), and 75% changed to opening cervix score 2. In this study, 75% of the cows experienced an optimum open cervix at 12 hours from the onset of estrus. It could be concluded that opening the external cervical canal of local Aceh cows reaches optimum at 12 hours from the onset of estrus.
