This study aimed to investigate the physical property changes of cervical mucus in repeated breeder Aceh cows. Six cows consisting three normal (K1) and three repeat breeders (RB) (K2) of adult Aceh cows were used. The characteristics of K1 group were at > 2 months post parturition, successful pregnancy following once insemination, and twice regular estrus cycle twice. The K2 were cows with normal estrus but failed to be pregnant after three times artificial inseminations. Cervical mucus samples (50 ml each) were collected by aspiration using a sterile catheter and disposable syringe. The comparisons of the physical properties of cervical mucus between fertile and repeat breeder cattle were as follows.. Cervical mucus unavailability/in small quantity was 0.00 vs. 66.67%, cloudy color was 0.00 vs. 66.67%, thick consistency was 0.00 vs. 100%, fern pattern was 0.00 vs 66.67%, spinnbarkeit was 5.16±1.60 vs. 2.83±2.02 cm and pH values was 7.33±0.57 vs 9.33±1.52. in conclusion, the physical properties of cervical mucus in repeat breeder Aceh were less in quantities, more cloudy, higher in viscosity, and higher pH as compared to normal fertile cows.

Penelitian ini dilakukan untuk mengetahui diameter folikel dan intensitas estrus pada sapi bali yang mengalami silent heat di kelompok ternak Sistem Pertanian Terpadu (SIPADU) di Kecamatan Mengwi Kabupaten Badung Provinsi Bali yang laksanakan pada bulan September – Oktober 2019. Sapi bali dikelompokan menjadi 2 (dua) kelompok yaitu yang mengalami silent heat dan yang mengalami estrus. Hasil penelitian menunjukkan rata – rata intensitas estrus kelompok sapi bali yang mengalami silent heat menunjukkan perbedaan yang bermakna (p<0,05) yaitu suhu vulva (37,68 + 0,32oC ), diameter vulva (27,64 + 4,28 mm), warna vulva (merah jambu, pembuluh perifer tidak terlihat) dan lendir vulva (tidak ada lendir sampai sedikit ada lendir), dibandingkan dengan kelompok sapi bali yang mengalami estrus yaitu suhu vulva (37,96 + 0,51oC), diameter vulva (31,19 + 5,66 mm), warna vulva (merah terang  sampai merah tua dan percabangan pembuluh perifer terlihat jelas) dan lendir vulva (kental transparan menggantung). Hasil penelitian dapat disimpulkan bahwa ada perbedaan antara itensitas estrus pada sapi bali yang mengalami silent heat dengan sapi bali yang menunjukkan estrus normal.
