ANTUNAC: The influence of live yeast cells (Saccharomyces cerevisiae) on the performance of grazing dairy sheep in late lactation. AbsTrACT A feeding trial was conducted in order to evaluate the influence of live yeast cells (saccharomyces cerevisiae) on milk production and composition, and on blood parameters in late lactation. The experiment was performed(More)
Immunoprophylaxis of porcine postweaning colibacillosis (PWC) caused by enterotoxigenic Escherichia coli (ETEC) expressing F4 fimbriae is an unsolved problem. Just as ETEC strains can exploit intestinal microfold (M) cells as the entry portal for infection, their high transcytotic ability make them an attractive target for mucosally delivered vaccines,(More)
Colidiarrhea and colienterotoxemia caused by F4(+) and/or F18(+) enterotoxigenic E. coli (ETEC) strains are the most prevalent infections of suckling and weaned pigs. Here we tested the immunogenicity and protective effectiveness of attenuated F18ac(+) non-ETEC vaccine candidate strain against challenge infection with F4ac(+) ETEC strain by quantitative(More)
Enterotoxigenic Escherichia coli (ETEC) infection is the most common type of porcine postweaning colibacillosis (PWC). Among fimbriae of porcine ETEC strains the best studied family of fimbriae are the members of F4 adhesins, existing in at least three variants: ab, ac, ad. Active immunization against porcine PWC is difficult due to: i) ETEC strains are(More)
Immunohistological identification/localization of immunomodulating neuropeptides [vasoactive intestinal polypeptide (VIP) and substance P (SP)] and enzyme nitric oxide synthase (NOS) as well as histomorphometric analyses of kinetics of their release and development of respective nerve fibers density during postnatal ontogenesis of porcine intestinal mucosal(More)
The objectives of this study were to examine the influence of body condition of cows on metabolic and antioxidative status, as well as to investigate the relationship between metabolic indicators of lipid mobilization and oxidative stress during transition period. The study was conducted on 24 Holstein-Friesian dairy cows divided into 2 groups according to(More)
One of the major post-parturient complications in dairy goats is the retention of foetal membrane (RFM), which negatively influences their health, reproductive efficacy and welfare. The aim of this study was to compare the efficiency of intrauterine either ozone (OZ) or antibiotic (AB) treatments to establish the use of OZ as a novel and potential(More)
Ozone therapy has been in use since 1896 in the USA. As a highly reactive molecule, ozone may inactivate bacteria, viruses, fungi, yeasts and protozoans, stimulate the oxygen metabolism of tissue, treat diseases, activate the immune system, and exhibit strong analgesic activity. More recently, ozone has been used in veterinary medicine, particularly in(More)
The aims of this study were to determine the presence and quantities of antioxidative status and oxidative stress (OS) variables in the seminal plasma and spermatozoa of bulls of varying age during cold and warm periods of the year, and to establish the correlation of these variables with semen quality parameters. The study was conducted on two groups each(More)
