The presented study demonstrates the influence of lunasin, a bioactive peptide isolated from seeds of winter triticale, on the proliferation of neoplastic cells. In order to conduct investigations, 2S fraction low-molecular-weight albumin proteins were extracted. SDS-PAGE electrophoresis separation of extracts indicated the presence of a 5 kDa pept...

The investigation was performed on 75 of Golden Retriever puppies. Faecal samples were collected on the 42 day of the puppies life (control). Probiotic preparation was administered on 43 day of the puppies life and 10 days after the application of the probiotic, faecal samples were collected again (on 53 day of puppies life). All isolates of Campyl...

The aim of this study was to check the influence of low temperatures 4° C on the frequency of occurrence of these bacteria in poultry meat. Samples of poultry meat (n = 300) were collected randomly from selected slaughterhouses. Identification of C. coli was performed using an API test and PCR reaction. It was found that the chilling effect of redu...

This study was conducted to determine the prevalence of Campylobacter spp. isolated from dogs’ faecal samples. From June 2012 to June 2013, a total of 210 faecal samples from pet dogs living in different kennels (n = 210) were collected by the owners in Greater Poland Voivodeship, Poznań District, Poland. The study revealed that 105 out of 210 faec...

Salmonelloses are among the most common animal-borne infections. The most frequent causes of their occurrence are contaminated chicken eggs. For this reason, the control of bacteria from the Salmonella genus living in the cloaca of laying hens can contribute to the reduction of spreading levels of infections with these bacteria. The most popular me...

Making good alfalfa silage is troublesome because alkaline products of protein degradation neutralise organic acids during the ensiling process. In order to improve the course of fermentation, it seems appro-priate to add preparations which facilitate ensiling, e.g. additives that contain in their composition propionic and formic acids (16). When f...

Numerous studies have shown that consumption of soybean products decrease the risk of cancers in humans. Experiments at the molecular level have demonstrated that in most cases proteins and peptides are responsible for the anticancer properties of soybeen. Special attention should be paid to lunasin — a peptide described for the first time 16 years...

The investigations were conducted on 60 Holstein-Friesian dairy cows (at age 3 year and weight 590 kg) kept in tie-stall barn. The animals were divided into 3 groups of 20 heads each. The control group (K) was fed diets without probiotics, group (EM) – was fed diet with the addition of EM probiotic (dose of 150 ml · t −1 TMR) and group (T) – was fe...

Abstract. The investigations were conducted on 60 Holstein-Friesian dairy cows (at age 3 year and weight 590 kg) kept in tie-stall barn. The animals were divided into 3 groups of 20 heads each. The control group (K) was fed diets without probiotics, group (EM) – was fed diet with the addition of EM probiotic (dose of 150 ml × t–1 TMR) and group (T)...

Streszczenie. Escherichia coli stanowi ważny czynnik powstawania biegunek sekrecyjnych u prosiąt. Istotna okazuje się lekooporność szczepów tych bakterii na stosowane w leczeniu tej grupy zwierząt antybiotyki. Prowadzone badania miały na celu określenie wybranych cech feno-typowych izolatów E. coli izolowanych od prosiąt wykazujących biegunkę oraz...

Streszczenie. Sorgo, będąc rośliną dnia krótkiego, nie tworzy w warunkach Polski dojrzałych nasion, wytwarza jednak obfity plon zielonej masy. Z tego względu wykorzystuje się tę roślinę na kiszonkę uzupełniającą obok kiszonki z kukurydzy. Cel pracy dotyczył analizy składu chemicz-nego kiszonki z kukurydzy i właściwości antagonistycznych mikroorgani...

Summary. Being a short day plant, in Polish climatic conditions, sorghum does not produce mature seeds, although it yields high forage harvest and, therefore, plans are made to utilise this plant as maize substitute. The aim of the performed analyses was to assess chemical composition and antagonistic properties of microorganisms present in the sil...
