Introduction
I am a veterinarian, an animal husbandry engineer, and a data scientist. My primary area of research is dairy cattle health and herd health management, with a particular focus on the transition period. I am currently delving into the functionality of the innate immune system in dairy cows, studying conditions such as metritis, as well as subclinical and clinical endometritis. Additionally, I am exploring the effects of metabolic diseases on reproduction. Concurrently, I am developing a platform

Background
Actinobacillus pleuropneumoniae is a prevalent respiratory pathogen causing substantial economic losses in swine production worldwide. The bacterium's ability to rapidly develop antimicrobial resistance (AMR) poses a significant challenge to effective treatment and control. In Poland, limited data on A. pleuropneumoniae serotype distribu...
Background
Elevated BHB levels are hypothesized to influence hepatic antioxidant enzyme expression and activity, contributing to oxidative response. However, the impact of BHB between 0.8 and 1.2 mmol/L on these mechanisms remains unclear. We hypothesized that elevated serum BHB levels would influence the hepatic expression of antioxidant genes (SO...
Embryo implantation in the mare occurs just over one month after fertilization, coinciding with the production of chorionic gonadotropin. The factors that regulate this late implantation in the mare, and whether they are unique to horses or shared with more invasive embryo implantation in other species, remain poorly understood. This study aimed to...
Background
Porcine respiratory disease complex (PRDC) significantly impacts the swine industry worldwide, leading to economic losses due to poor growth performance, reduced feed efficiency, higher medication costs, and adversely affecting pig welfare by causing clinical symptoms such as fever, cough, loss of appetite, lethargy, and dyspnea.

Probiotic feed additives have attracted considerable research interest in recent years because the effectiveness of probiotics can differ across microbial strains and the supplemented macroorganisms. The present study was conducted on 16 lambs divided equally into two groups (C—control and E—experimental). The examined lambs were aged 11 days at th...
Simple Summary
The concept of the cardio–renal axis is based on the assumption that kidney dysfunction is a secondary consequence of heart disease, a mechanism observed in dilated cardiomyopathy (DCM). Traditional serum markers are not always effective, especially in the early stages of kidney disease. Thus, there is a need to find more sensitive m...

Simple Summary
The transition period for high-yielding dairy cows, marked by calving and the onset of lactation, presents a substantial risk of oxidative stress. This stress can have adverse effects on cow health and milk production yield. Our research aimed to assess the effectiveness of selenitetriglycerides as an oral supplement for alleviating...
During the transition period, the cow's body activates adaptive mechanisms aimed at adjusting to the changing demand for energy and nutrients, which are necessary for the growing fetus and the subsequent start of milk production. This time is also associated with an increased risk of metabolic diseases and reproductive disorders. Our study aimed to...
