“…Te fndings of this research also demonstrated a signifcant association between cattle parity and the prevalence of dystocia, with monoparous cattle being fve times (OR � 5.2; P < 0.05) more likely to have dystocia than pluriparous cattle (Table 5). Tis could be attributed to the smaller size and slower growth of the young heifers' pelvic dimensions [64]. Tis result is in agreement with the results of Hiew [65] and Benti and Zewdie [21], who stated that dystocia is more prevalent in monoparous cattle than pluriparous cattle.…”

Reproduction is a basic requirement for efficient cattle production to continue or cease; whereas, reproductive disorders are the leading cause of economic loss in the cattle industry. To determine the prevalence and associated risk factors of major reproductive disorders in cattle in the Tole district, a cross-sectional study design was conducted from October, 2020, to October, 2021. To identify potential risk factors for cattle reproductive disorders, a multivariable random effect logistic regression analysis was used. A total of 400 randomly selected cows were examined, and 37.8% of them had at least one reproductive disorder. The three main reproductive disorders observed in the study area were abortion (17.8%), stillbirth (4.8%), and dystocia (3.3%). Risk factors for reproductive disorders in the study area included the calving season (OR = 3.7, 95% CL-1.37–7.18) and the accessibility of dogs to cattle (OR = 2.5, 95% CL-1.64–3.85). Accessibility of dogs to cattle in the study areas was also a risk factor for abortion (OR = 7.5, 95% CL-3.59–15.54). The present study also identified parity (OR = 5.2, 95% CL-1.05–26.04) as a risk factor for dystocia in cattle in the study areas. This demonstrated that losses in cattle production in the study areas are significantly attributed to reproductive problems. Hence, it is essential to increase public awareness of how reproductive disorders affect cattle production and to develop and implement appropriate control measures for these disorders. The causes of abortion and dystocia in various areas should be precisely identified and described through further research.

“…However, the herd-level prevalence of perinatal calf mortality is positively skewed [4] and can vary between 0 and 30.6% in dairy herds [5]. Important risk factors for PM include age at first calving [6], breed of dam, breeding method, calving management, fetomaternal health status, length of gestation [7], gestational nutrition, calf sex, and sire [8]. While many risk factors for PM are not under management control (year of calving, month of calving, twin calving, primiparity, previous perinatal mortality, and fetal gender) [2], many others are modifiable [8].…”

Bovine perinatal mortality due to infection may result either from the direct effects of intrauterine infection and/or the fetal response to such infection, leading to the fetal inflammatory response syndrome (FIRS). Both intrauterine infection and FIRS, which causes multi-organ damage and involution of immune organs, compromise fetal survivability, sometimes fatally. Organ injury associated with FIRS may, in addition to causing fetal mortality, irreversibly compromise extrauterine adaptation of the neonate, a recognized problem in human fetuses. Diagnosis of intrauterine infection and of FIRS requires related, but independent analytical approaches. In addition to detection of pathogens, the immune and inflammatory responses of the bovine fetus may be utilized to diagnose intrauterine infection. This can be done by detection of specific changes in internal organs and the measurement of antibodies and/or elements of the acute phase reaction. Currently our ability to diagnose FIRS in bovine fetuses and neonates is limited to research studies. This review focuses on both the fetomaternal response to infection and diagnostic methods which rely on the response of the fetus to infection and inflammatory changes, as well other methods which may improve diagnosis of intrauterine infection in cases of bovine perinatal mortality.

“…In Poland the mean PM rate was 8.1 and 4.8% in first and later calvings, respectively [5]. Important risk factors for PM include age at first calving [6], breed of dam, breeding method, calving management, feto-maternal health status, length of gestation [7], gestational nutrition, calf sex and sire [4].…”

Infection exposure, detection and causes of death in perinatal mortalities in Polish dairy herds

et al. 2017

The objective of this study was to determine the prevalence and types of infections in perinatal mortality (PM) cases from Polish dairy farms and the relevance of the presence of infection to the cause of death. This prospective longitudinal study was carried out on 121 PM and 21 control calves with a gestation of ≥260 days. Six control calves were euthanized and examined using the same protocol as for PM calves. Material was collected over a 20-month period between November 2013 and June 2015. The PM and control calves were collected from 29 to 5 herds, respectively. Blood samples from calves were tested for antibodies to Neospora caninum, glycoprotein B of BoHV-1, BVDV and SBV using ELISAs and Leptospira hardjo and Leptospira pomona with the microscopic agglutination test. Brain and kidney samples from all PM and six euthanized control calves were tested using real time PCR to detect Neospora caninum, pathogenic Leptospira spp., BoHV-1 and SBV; brain was examined histopathologically for detection of N. caninum cysts. Samples from eight inner organs from all PM and six control calves were cultured aerobically, anaerobically and microaerobically. Ear samples from all PM and control calves were tested for BVDV using an antigen ELISA. In total, 21.5% of PM calves were infected (antigen and/or antibody-positive) in utero; none of the control calves were infected. Direct evidence of infection (culture, Ag-ELISA, PCR, histopathology) was detected in 9.1% of PM calves. Gestation length in infected singletons was shorter than in uninfected singletons (274 ± 8 vs. 279 ± 7 days; P < 0.01). The odds ratio for diagnosis of infection in single pregnancies ≤275 days was 3.75 (95% CI:1.2-12.1), (P < 0.05). Infection was the cause of death in 10% of calves. The most common infections detected in these Polish PM calves were parasitic (11.6% of PM cases), viral (7.4%) and bacterial (5%). This study demonstrated that indirect evidence of infection is detected more frequently than direct, coinfection is rare, infection is rarely accompanied by gross lesions and is rarely a cause of death in cases of PM.
