We evaluated the conventional acute stress model in mice and investigated the stress-induced changes in concentrations of plasma lipids and hormones such as corticosterone (CORT), insulin, glucagon, triiodothyronine (T3), and thyroxine (T4). Stress induction for 120 min using tape-immobilisation and restraint resulted in an increase in the plasma levels of CORT, insulin, glucose, total cholesterol (TC), and low density lipoprotein-cholesterol compared with unstressed mice. Stress also resulted in a decrease in the concentrations of T3, T4, triglycerides (TG), and high density lipoprotein-cholesterol. However,...

The aim of this study was to investigate a possible effect on thyroid hormone concentrations in peripheral blood in sheep submitted to isolation, restraint and shearing. Circulating T3, T4, fT3 and fT4 concentrations of No. 40 Pinzirita sheep were evaluated under baseline conditions, 24 h before isolation, restraint and shearing (T0), after isolation (T1), and after restraint and shearing (T2), with respect to the influence of a previous shearing experience (just shorn). A control group of 40 sheep was evaluated under baseline conditions (T0). Two-way RM ANOVA showed a significant effect of previous experience...

The effect of adding high or low protein content homologous seminal plasma to boar spermatozoa on the progressive motility of the spermatozoa after storage for three days, and at a 1 : 4 dilution ratio was investigated. A total of 32 ejaculates collected from four boars (eight ejaculates per boar) with high seminal plasma protein content (4%, HH-group) and 32 ejaculates collected from four boars (eight ejaculates per boar) with low seminal plasma protein content (2%, LL-group) were evaluated. The fresh ejaculate samples were centrifuged at 1000 g for 10 min at 4 °C to separate the spermatozoa from the seminal plasma. After centrifugation,...
Screening of antimicrobial resistance and molecular detection of fluoroquinolone resistance mechanisms in chicken faeces-derived Escherichia coli Original Paper

This study was aimed at investigating the resistance to antimicrobial agents and to assess the predominant molecular mechanisms of fluoroquinolone resistance in faecal E. coli strains isolated from chickens farmed in central Poland. Bacterial strains were isolated from faecal samples of chickens reared on four conventional and one organic farm. The disk-diffusion method was applied to assess antimicrobial resistance and the prevalence of particular resistance mechanisms to fluoroquinolones was determined using specific polymerase chain reactions and sequencing of the gyrA and parC genes. Rep-PCR was used to determine the...

This study was conducted to determine the effect of supplementing diets with lactulose on growth performance, carcass characteristics, faecal microbiota, and blood constituents. A total of 324 one-day-old Ross 308 mixed-sex broiler chicks with an average initial body weight of 38 g were used in a 35-day growth assay. There were 18 birds/pen and six pens/treatment with food and water available ad libitum. Treatments consisted of a corn-soybean-meal-based diet with 0, 0.25 and 0.5% of lactulose. The results indicated that body weight gain (BWG) was improved (linear effect, P < 0.05) by increasing the concentration of lactulose in...
Ramification of the celiac artery in the greater flamingo (Phoenicopterus roseus)Original Paper

The purpose of this study was a description of the species-specific characteristics of the celiac artery in greater flamingos (Phoenicopterus roseus). In the greater flamingos examined in this study, it was observed that the celiac artery (a. celiaca) originated from the right ventrolateral surface of the descending aorta (aorta descendens) at the level of the fourth thoracic intervertebral junction. The celiac artery was observed to give off branches to the oesophagus, proventriculus, gizzard, spleen, liver, gall bladder, duodenum, pancreas, jejunum, ileum and caecum. After giving off the dorsal proventricular artery (a....

An eight-year-old, 4.9 kg, intact male mongrel dog presented with progressive weight loss, anorexia, vomiting, diarrhoea, and open-mouth breathing. A thoracic radiograph showed significant pleural effusion. Upon removal of the pleural effusion, an oval-shaped soft-tissue density mass was identified above the heart base. Two months later, the dog's condition worsened severely, and he was euthanised. A complete necropsy showed all intrathoracic structures were encapsulated by a fibrinous material. A large granuloma was attached between the right cranial lung lobe and the trachea. The cytological evaluation of the pleural effusion showed numerous negative-staining...
