Special Issue Information

Dear Colleagues,

Reproductive performance is a key parameter for the economic efficiency of a livestock company. However, fertilization is affected by several seasonal-, environmental- and animal-related factors. Technological tools have been involved in the prognosis of animals’ subfertility to support the good reproductive management of farms. New diagnostic laboratory tests and protocols, imaging, infrared thermography, special software, artificial intelligence, nanotechnology, antibiotic alternatives, sensors to measure animals’ physiological and environmental/climate variables, as well as other modern technological applications are assisting in improving reproductive performance.

The scope of this Special Issue is to make public information about technological applications concentrated on the improvement of reproductive efficiency; fertilizing capacity; and the prognosis of fertility.

We invite you to share your recent findings via this Special Issue.

The primary aim of this study was to investigate the effect of the pelvic dimensions of Holstein cows on the traction forces during parturition. Additionally, the relationship between calf measurements and traction forces was explored. For this purpose, a modified in vitro biomechanical model simulating obstetric tractions was used. For the requirements of the experiment, six bone pelvises of deceased Holstein cows were collected based on their estimated pelvic inlet area (EPA) and prepared. Additionally, six stillborn calves were collected based on their body weight (BW). The parameters of the pelvic inlet and cavity were measured using computed tomography (CT). Using the simulator, every calf was pulled in a random order through all pelvises, realizing a total of 36 obstetrical tractions, and the required forces were documented with appropriate software. In each extraction, three peaks of forces were recorded, with the first peak occurring at the entrance of the elbows into the maternal pelvic cavity, the second peak at the entrance of the thorax, and the third at the entrance of the calf’s pelvis. Logistic regression revealed an exponential relationship between pelvic parameters and traction forces for the entrance of the elbows and the pelvis, with the recorded forces being higher in the two smallest pelvises and stabilizing at a lower level thereafter, while for the entrance of the thorax, the correlations were either exponential or linear. The adjusted coefficients of determination (r2) were generally above the threshold of 0.5 for the entrance of the elbows and pelvis and lower (0.3–0.4) regarding the thorax and were statistically significant (p < 0.05) in all cases. Regarding the relationships between the calf dimensions and the required traction forces, the types of correlations were primarily linear and of lower magnitude. The combination of pelvic and calf parameters in a multivariate model resulted in an r2 of 0.72 for the entrance of the elbows using the pelvic diagonal and calf’s body weight, an r2 of 0.62 using the pelvic area and calf’s thoracic circumference, and an r2 of 0.75 using the pelvic diagonal and calf’s fetlock joint width. In conclusion, under the conditions of the present experimentation, the applied traction forces were mainly influenced by the pelvic dimensions in an exponential manner, whereas the calf body measurements showed a weaker effect. Based on these findings, critical cut-off points exist, different for every pelvic parameter, below which a significant increase in the required traction forces is expected. Full article
