“…Cervical mucus secretion is influenced by estrogen. There was a negative relationship between Na and both of K and Cl concentrations in the current results, which agreed with the findings of Abd-El-Hafeez et al (2020), could be clarified by Coppock et al (1982), who reported that chloride is absorbed more efficiently than sodium in the posterior section of kidney and intestine. According to some studies, Na content was the only mineral that changed significantly during the 3 days preceding estrus (Cowan and Larson, 1979).…”

“…The cervical mucus properties at the moment of service/insemination affect pregnancy in cows, it is generally known that physicochemical alterations in cervical mucus occur during erectile ovarian steroids, aiding sperm penetration. While the determination of specific parameters such as spinnbarkeit, crystallization pattern, electrical conductivity, dry matter contents, and rheological values have been utilized to predict the optimum time for cattle insemination (Joshi et al, 2017;Ondho et al, 2019;Siregar et al, 2019;Abd-El-Hafeez et al, 2020).…”

“…Examination of fluids secreted in the female genital tract to determine fertility has become a major concern and cervical fluid is also involved in sperm survivability and delivery to the uterus (Kumar et al, 2012). Characteristics of CM can be utilized as a sign to detect the exact moment of artificial insemination and can be utilized as an indicator of reproductive health connected to estrous behavior, also, play a major influence in pregnancy success; thus they will boost the conception rate (Tsiligianni et al, 2000;Benbia et al, 2011;Verma et al, 2014;Joshi et al, 2017;Ondho et al, 2019;Siregar et al, 2019;Abd-El-Hafeez et al, 2020).…”

Alteration of the biophysical and biochemical characteristics of cervical mucus (CM) due to differences in steroid hormones through the estrus cycle leads to different pregnancy rates. This investigation aims to study the possible relationship between CM properties with biochemical profiles, macro-mineral levels, and steroid hormones concentrations, in reference with pregnancy rates of Egyptian Baladi cows. Fourteen Baladi cows were used and synchronized. The model log-likelihood ratio was highly significant (P=0.0009), and reported that the spinnbarkeit (SPK), electrical conductivity (EC), and crystallization (CRS) had significant effect on pregnancy rate. The 3 rd level of SPK (>13.5 cm) and EC (>15 mS/cm) showed significantly the highest effect (P=0.0016 & 0.0517, respectively) and a clear positive of estimate marginal effect (20.2543 & 10.6192, respectively) attitude towards the pregnancy rate. However, in case of the CRS, the significant effect was in the first two levels (P=0.0321 & 0.0425, respectively) with pregnancy rate, reverse the last 2 levels. Total proteins, cholesterol, glucose, potassium, and chloride levels, and estradiol concentrations were increased with increasing levels of SPK and EC, and appearance of typical fern patterns (first two levels of CRS), in contrast to sodium level and progesterone (P4) concentrations that decreased with elevating levels of SPK and EC and appearance of atypical fern patterns (last two levels of CRS). There was a close correlation between CM properties and steroid hormones (P4 & E2). So, alterations in CM properties, especially SPK, EC, and CRS, can be utilized to foresee estrus time and, as a result, insemination time.

“…A possible explanation for these differences could be the different times between the two measurements. Furthermore, it is notified that heat stress leads to changes in the physical and biochemical properties of cervical mucus at the time of insemination (Abd-ElHafeez et al, 2020). This can also be related to whether the cows are under heat stress.…”

| Cervical mucus is a biological environment that affects sperm survival and determines the ability of cows to become pregnant. Insemination based on cervical mucus characteristics may increase pregnancy rate. Therefore, this study's aim is to evaluate the extent to which the scores specific to the changes in physical properties of cervical mucus predict the probability of conception at insemination time. Cervical mucus in 36 clinically healthy Holstein cows was evaluated scoring system based on the five variables (colour, viscosity, spinnbarkeit, ferning and pH) describing appearance and characteristics of cervical mucus collected. Each parameter was graded from 0 to 3. Comparison of cervical mucus score including all parameters demonstrated a significant (P < 0.0001) increase between conceived cows' mean score (13.47) and non-conceived cows' mean score (10.59). All parameters of the cervical mucus score for non-conceived cows were reduced, with the change in viscosity (P < 0.05), spinnbarkeit (P < 0.01) and fern pattern (P < 0.01) being a significant. The highest conception rate was achieved in score 3 for all parameters of the cervical mucus. 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. In our study, mucus colour, viscosity, and ferning properties were found to be the important factors, which establish the fitness of cervical mucus for the occurrence of pregnancy in cows.

“…The estrus phase showed fewer microbes in the cervical mucus (Nur et al, 2020). The more cervical mucus produced, the higher the level of the lysozyme enzyme; thereby, the cervical mucus looks liquid and transparent due to the decreased number of bacteria (Abd-ElHafeez et al, 2020).…”

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.
