“…In our study the mean concentrations of calcium indicated significantly high concentrations in cases of both downer cow syndrome (25.25 ± 8.47 mmol/L) and dystocia (85.50 ± 8.46 mmol/L) in mixed breed cows. On the contrary, the incidence of downer cow syndrome has been linked with low calcium levels (Benzaquen et al 2015:186). However, such associations were not seen in this study, because the concentrations of calcium in most of the cows were within the normal ranges (2.0–2.8 mmol/L).…”

“…In downer cow syndrome, low mean concentration of calcium was observed in Brahman (1.98 ± 9.76 mmol/L) and Charolaise (0.78 ± 11.95 mmol/L) breed cows; however, no significant differences were indicated in the current study. This may be because of a lack of homogeneity in the number of cows within the different breeds, because low calcium is a known indicator for downer cow syndrome (Benzaquen et al 2015:186).…”

Minimising health problems and increasing yield have always been the objectives in livestock agriculture. Hence, increases in incidences of reproductive conditions in cattle farming pose a great threat to productivity and impose undesirable economic implications. This study aimed to examine the concentrations of different biochemical compounds in cows with reproductive conditions. Seventy-seven blood samples were collected from cows at different rural areas around Mafikeng, following cases of downer cow syndrome, dystocia, retained placenta, vaginal prolapse and abortion. Means of serum metabolites across the different reproductive conditions were statistically compared using Pearson’s chi-square test to determine variations of serum metabolites in cows of different breeds. In mixed breed cows, higher than normal calcium concentrations were observed in downer cow syndrome (25.25 ± 8.47) and dystocia (85.50 ± 8.46) cases. It was also observed that cholesterol concentrations were significantly low in abortion (2.52 ± 0.79), retained placenta (3.18 ± 0.61) and vaginal prolapse (2.37 ± 0.97) cases in Afrikaner cows. The study showed that Brahman (43.1%) and Afrikaner (43.1%) breeds were mostly affected by downer cow syndrome. Additionally, the occurrences of downer cow syndrome (53.9%) and abortions (60%) were mostly observed in cows of 1–3 years, in second and first parities, respectively. This study proves that concentrations of calcium, urea or blood urea nitrogen (BUN), magnesium and cholesterol are significantly altered in incidences of reproductive conditions in cows of different breeds. It is also shown that serum biochemistry is affected by reproductive conditions in cows of different ages and parity. This data serves as a tool that could be used to enhance research in animal production and reproduction.

“…Recently, de Boer et al (2015) reported that cows with ≥25% PMN in the uterus within 4 d from calving had decreased time to pregnancy compared with cows with <25% PMN in the uterus. Probably, similarly to dystocia, VLS may lead to a decrease in DMI (Proudfoot et al, 2009), an increase in fat mobilization, and a reduction in blood calcium concentration (Martinez et al, 2012;Benzaquen et al, 2015), which has been associated with reduced PMN function (Hammon et al, 2006;Martinez et al, 2012Martinez et al, , 2014. Therefore, these data indicate that uterine pathogens are present in all cows shortly after calving; however, the response to the pathogens determine disease outcome.…”

The main objective was to evaluate the association between vulvovaginal laceration and uterine diseases in dairy cows. The secondary objectives were to evaluate the association between vulvovaginal laceration and cyclicity, and reproductive performance. The vulvovaginal region of 660 Holstein cows from a 5,000 lactating-cows herd was inspected at 4d in milk (DIM) for the presence of lacerations, and scored (VLS) as follows: 0=no laceration; 1=laceration <2cm at the dorsal commissure of the vulva or lateral walls of the vulva/vagina; 2=laceration ≥2cm at the dorsal commissure of the vulva or at the lateral walls of the vulva/vagina, or both. Vaginal discharge was scored at 4, 6, and 8 DIM for diagnosis of metritis, and then at 32 DIM for diagnosis of purulent vaginal discharge (PVD). Data were analyzed using LOGISTIC and PHREG procedures of SAS. Cows with VLS 2 had greater incidence of metritis than cows with VLS 0 (69.1 vs. 42.4%), and cows with VLS 1 tended to have greater incidence of metritis than cows with VLS 0 (52.0 vs. 42.4%). Cows with VLS 2 had greater incidence of PVD than cows with VLS 0 (56.5 vs. 43.1%). A lower proportion of cows with VLS 2 than VLS 0 were cyclic by 64 DIM (70.0 vs. 86.8%). A lower proportion of cows with VLS 2 than VLS 0 were pregnant at 60 d after first AI (28.7 vs. 33.6%). Proportion of pregnant cows at 60d after AI tended to be lower for VLS 1 than VLS 0 (28.4 vs. 33.6%). Hazard of pregnancy by 300 DIM was not affected by VLS. Hazard of pregnancy was decreased for cows with metritis, PVD, and anovular cows. In summary, vulvovaginal laceration was associated with uterine disease and cyclicity, which were negatively associated with reproductive performance. Vulvovaginal laceration was recognized as a risk factor for postpartum uterine disease.

“…Without timely treatment, this disease will exert great influences on fetus and maternal outcomes, such as maternal systemic failure and fetal death. Mortality rate of dystocia fetuses during the perinatal period is much higher compared with that in normal pregnancy ( 5 , 6 ).…”

Effects of general anesthesia combined with epidural anesthesia on the postoperative cognitive functions in pregnant women with dystocia were investigated. Postoperative cognitive functions of 84 dystocia pregnant women treated with cesarean section were retrospectively analyzed. Patients who received general anesthesia were included in group A (n=42), and those who received general anesthesia combined with epidural anesthesia were included in group B (n=42). Mean arterial pressure (MAP), heart rate (HR) and bispectral index (BIS) at different time-points after anesthesia in the two groups of patients were observed and compared. Recovery of anesthesia such as the recovery time of spontaneous breathing, recovery time of orientation and time of eye opening were observed and compared between two groups of patients. Mini mental state examination (MMSE) scores were obtained and compared between the the groups of patients at different time-points after operation. Three vital signs (MAP, HR and BIS) were not significantly different between group A and B at the same time-point (P>0.05) and the maintenance of anesthesia was satisfactory. Compared with group A, postoperative recovery time of spontaneous breathing, recovery time of orientation and the time of eye opening in group B were all significantly shorter (P<0.05). In addition, MMSE scores of patients in group B, 2 and 12 h after operation were 24.33±1.61 and 26.41±1.83 points, respectively, which were significantly improved compared with those of patients in group A (20.45±1.58 and 22.39±1.72 points, respectively) (P<0.05). In conclusion, recovery of postoperative cognitive functions in pregnant women with dystocia who received general anesthesia combined with epidural anesthesia was shorter to that of those who only received general anesthesia.
