“…The detrimental effect of high mucus pH at the time of artificial insemination on conceiving could be due to a direct effect of the pH on the sperm or an alteration of the structure of cervical mucus. In contrast to our findings, some earlier studies (Damarany, 2020;Ningwal et al, 2018) recorded more alkaline pH in the pregnant cow. Correa et al (2001) demonstrated that the pH increases of cervical mucus due to exposure to air when in vitro tests are performed.…”

“…The zero score of fern pattern was not observed both in pregnant and non-pregnant cows. This finding is in agreement with Ningwal et al (2018) who reported that none of the pregnant and non-pregnant animals had nil fern pattern.…”

“…A higher conception rate in spinnbarkeit with a score of three may be due to an increase in the capacity of sperm to penetrate the cervical mucus. These results are in agreement with Ningwal et al (2018) who observed higher spinnbarkeit in cervical mucus of cows that became pregnant than non-pregnant ones. Similarly, Rangnekar et al (2002) notified spinnbarkeit of cervical mucus in the range of 12 to 18 cm in fertile estruses.…”

“…Our study demonstrated that the fern pattern scores of mucus at the time of artificial insemination were positively correlated with probability of conception Ningwal et al (2018) who reported increased pregnancy rate in cows with typical arborisation pattern compared to those atypical patterns. The zero score of fern pattern was not observed both in pregnant and non-pregnant cows.…”

| 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.

“…Bhat et al (2015), Bernardi et al (2016) and Siregar et al (2019) reported that there was a relationship between viscosity of vaginal mucus discharge and conception rate in cows. Ningwal et al (2018), Kumar et al (2019) and Hanumant et al (2019) stated that pH of vaginal mucus discharge affected the conception rate in cows. Atkins et al (2010), Perry et al (2014) and Mogheiseh et al (2019) found a positive relationship between estradiol-17β concentrations and intensity of estrus sings expression in cows.…”

The current research aimed to study the conception rate of Egyptian native cows as influenced by vaginal mucus discharge (VMD). Forty cows were used in the experiment and were followed up after two-week postpartum. Vaginal mucus discharges were divided into three categories according to transparency ( transparent, cloudy and dirty), viscosity (thin and thick) or pH (7-7.5, 7.5-8 and ˃8). The results indicated that the percentage of cows that conceived which have transpa rent vaginal mucus discharge (VMD) during estrus were significantly (P <0.05) higher (73.3%) compared with cows which have cloudy and dirty vaginal mucus (40 and 20%), respectively. The percentage of cows that conceived which have thin vaginal mucus during estrus was significantly (P <0.05) higher (87.5%) compared to those cows which have thick vaginal mucus (25%). The conception rate was significantly (P <0.05) higher (78.6%) in cows which have vaginal mucus pH level at estrus ˃8 compared with those cows which had vaginal mucus pH value ranging from 7 to 8. No significant difference in plasma progesterone concentrations during estrus in cows which have different vaginal mucus pH in pregnant and non-pregnant baladi cows. However, concentrations of estradiol-17βduring estrus in pregnant cows were significantly (P <0.05) higher than non-pregnant cows. Concentration of estradiol-17β at estrus was significantly (P <0.05) higher in cows which have strong estrus intensity expression compared with cows having weak estrus intensity expression. In conclusion, the results clarified that the cows, which had vaginal mucus discharge (VMD): transparent, thin, and pH value at estrus ˃8 recorded higher conception rate. Estradiol-17β concentration was significantly (P <0.05) higher during estrus period in cows, which displayed high estrus intensity.
