Physical Properties of Cervical Mucus of Repeat Breeder Aceh Cattle (PERUBAHAN FISIK MUKUS SERVIKS PADA SAPI ACEH YANG MENGALAMI KAWIN BERULANG)

Abstract

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.

The Validity of the Scores of Cervical Mucus during Artificial Insemination for Estimating the Probability of Conceiving in Clinically Healthy Cows

“…The cows included in this study had alkaline pH of cervical mucus at the time of artificial insemination. This is well consistent with previous studies (Zaman et al, 2013;Siregar et al, 2017). No significant difference (p=0.1) was found in the mean pH score of their cervical mucus at the time of artificial insemination from pregnant and non-pregnant cows.…”

“…On the other hand, thick, highly viscous (0 th score) of mucus was observed in 8.33% of cows and none of these cows conceived. These results are in agreement with Siregar et al (2017). Increased viscosity adversely affects sperm swimming speeds and survival of spermatozoa (Zimmer and Riffell, 2011).…”

“…Some studies which relates cervical mucus with conception rate have been noticed in cattle (Bernardi et al, 2016;Hanumant et al, 2019). It has been reported that the physical property changes of cervical mucus may be related to lack of pregnancy in cows (Bernardi et al, 2016;Siregar et al, 2017;Parikh et al, 2018). Insemination based on cervical mucus characteristics may increase pregnancy rate (Modi et al, 2011).…”

Detection of carbohydrate distribution in the testis of Aceh bull using periodic acid Schiff staining

“…The population of this cattle tends to decline due to low productivity. To overcome this problem, various research has been carried out to determine the causes of low productivity of Aceh cows, such as repeat breeding disorders as reported by Siregar et al [2], Thasmi et al [3], and Wahyuni et al [4]. Research related to the reproductive potential of Aceh bull which focuses on the spermatogenesis including identification and determination of seminiferous epithelium stages and spermatid development has been reported by Wahyuni et al [5].…”
