Factors Affecting Milk Productivity, Milk Quality and Dairy Cow Health.

Milk and dairy products are considered important sources of nutrients in human nutrition due to their content of high-quality protein, minerals, vitamins, and energy [...

Simultaneous Presence of Antibodies against Five Respiratory Pathogens in Unvaccinated Dairy Calves from South-Western Poland.

Bovine Respiratory Disease (BRD) poses a significant threat to cattle welfare worldwide, affecting their respiratory system and causing substantial economic losses. BRD is multifactorial in nature. This research aimed to investigate the serological profile of calves for the five main bovine respiratory pathogens.

Comparison of Antibiotic Use and the Frequency of Diseases Depending on the Size of Herd and the Type of Cattle Breeding.

Diseases are responsible for losses in livestock production by increasing animal mortality and reducing productivity. The administration of antibiotics can help mitigate these negative effects. However, inappropriate use can lead to severe complications, such as raising antibiotic resistance.

Milk Odd- and Branched-Chain Fatty Acids as Biomarkers of Rumen Fermentation.

Cow's milk and dairy products are the primary sources of OBCFAs, which have beneficial health properties. The goal of this study was to identify the factors that influence the content of OBCFAs in cow's milk and to indicate which OBCFAs can serve as biomarkers for fermentation processes. The content of OBCFAs in milk depends on the species of ruminants, with studies showing that this varies between 3.

Genetic Evaluation of Bovine Papillomavirus Types Associated with Teat Papillomatosis in Polish Dairy Cattle with the Report of a New Putative Type.

Teat papillomatosis is reported to be one of the factors causing mastitis and milk losses in dairy cattle. Little is known about bovine papillomavirus (BPV) circulation in the European cattle population, and no reports can yet be found about its prevalence in Polish herds. In this study, 177 BPV-like lesions were collected from teats of 109 slaughtered cows.

Evaluation of Suitability of New Bedding Material Obtained after Straw Biogasification for Dairy Cows.

This study aimed to compare the biomass obtained via the biogasification of straw with the classic bedding material, wheat straw. It was divided into two stages. In the first stage, a laboratory evaluation of the bedding materials was carried out, taking into account dry matter, pH, and water absorption.

Application of , and Mixture Extracts in a Rabbit Model with Experimentally Induced Infection.

The study evaluated the anti-colibacteriosis efficacy of herbs in experimental infection by rabbit pathogenic strain of O103 . It also studied the effects of herbal mixture added to feed or water on blood parameters. This animal model was used since some strains pathogenic for rabbits are similar to the strains that are pathogenic to humans.

Update of the helminth fauna in Eurasian lynx (Lynx lynx) in Poland.

The Eurasian lynx (Lynx lynx) is a strictly protected species of large carnivore in Poland. It inhabits forest complexes in north-eastern Poland and the Carpathian region in southern Poland. The status of the lynx within Poland requires special attention because its range decreased between 1980 and 2001 and has not yet recovered.

Antimicrobial Susceptibility and Genotypic Characteristic of Campylobacter spp. Isolates from Free-Living Birds in Poland.

Campylobacter spp. is the most commonly reported, bacterial cause of human foodborne infection worldwide. Commercial poultry and free-living birds are natural reservoirs of three particular species: Campylobacter jejuni, Campylobacter coli, and Campylobacter lari.

First molecular characterization of Sarcocystis tenella in Tatra chamois (Rupicapra rupicapra tatrica) in Poland.

In this study, sarcocysts from three Polish Tatra chamois were isolated and identified using morphological and molecular methods for the first time. Six cysts were found in the latissimus dorsi muscle and another two in the diaphragm. No sarcocysts were detected in the myocardium, tongue, and esophagus.

Molecular characterization of Sarcocystis species from Polish roe deer based on ssu rRNA and cox1 sequence analysis.

Sarcocysts from four Polish roe deer were collected and examined by light microscopy, small subunit ribosomal RNA (ssu rRNA), and the subunit I of cytochrome oxidase (cox1) sequence analysis. This resulted in identification of Sarcocystis gracilis, Sarcocystis oviformis, and Sarcocystis silva. However, we were unable to detect Sarcocystis capreolicanis, the fourth Sarcocystis species found previously in Norwegian roe deer.

Crystal chemistry and physical properties of the nonmagnetic Kondo compound HfAs1.7Se0.2.

Single crystals of HfAs(1.7)Se(0.2) are grown by chemical transport reaction and their chemical composition characterized in detail by various analytical methods.
