OBJECTIVE Contamination of feeds with pathogenic microflora and mycotoxins constitutes a serious threat both for animals and humans. The aim of the study was to determine the degree of risk of the occurrence of microscopic fungi, selected bacteria and mycotoxins from the trichothecene group in poultry feeds in western Poland. RESULTS In feed mixtures, the(More)
The effects of lysozyme monomer and thermochemically modified lysozyme on the microflora and sensory attributes of heated and unheated ground pork were investigated in this study. The dimer and trimer fractions of the modified lysozyme were 36.1 and 33.5%, respectively. The modified lysozyme exhibited higher hydrophobicity (40,600 U/mg of protein) and(More)
The aim of the study was to assess the effect of lysozyme monomer and dimer as well as modified lysozyme preparations on the shelf life of chicken carcass elements (breast muscles) cold stored at 3°C±1°C. Total counts of aerobic bacteria were determined and sensory examination of the product was conducted. Analyses showed that surface application of dimer(More)
Ergosterol (ERG) content, being an indicator of fungal biomass, was analyzed in samples of eggshell, egg white, and egg yolk from eggs from farms with intensive management systems of layer hens (i.e., cage and litter housing). Moreover, analogous samples were analyzed from eggs from farms in the western central part of Poland, where layer hens were kept in(More)
Pheasant eggs of different colors differ with regard to physical properties. This study was conducted to ascertain the intensity of infestation by microscopic fungi based on egg color. Settling intensity by microscopic fungi of pheasant egg shells and the content of eggs of different color during a 7-d storage period was investigated. The content of(More)
The aim of this study was to evaluate the effectiveness of ethyl alcohol (75%) disinfection of Japanese quail (Coturnix coturnix japonica) hatching eggs and analysis of microbial contamination of eggs during incubation, depending on their location in the setter. Disinfected eggshells were found to have lower total bacteria (TBC) and fungi (TFC) count.(More)
Bacteriocins are small peptides with antimicrobial activity, that are produced by bacteria. Four classes of bacteriocins produced by lactic acid bacteria have been defined. Class IIa bacteriocins are promising candidates for industrial applications due to their high biological activity and their physicochemical properties. Divercin AS7 is a class IIa(More)
