The research objective was to determine the degree of microbial contamination of the soil from a silver fox farm and animal feces in accordance to the season of the year and sampling location. The air temperature and relative humidity as well as sample moisture at the sampling sites were also evaluated. The studies were performed from October until September. Soil samples were collected from under the cages (GI), between the rows of the cages (GII) and at a distance of 30 m from the cages (GIII), whereas fox feces were taken from under the cages (KI), between the rows of the cages (KII) and 45 m from the cages (KIII). The soil and feces samples underwent qualitative and qualitative microbial assessment. The total count of mesophilic, psychrophilic, proteolytic bacteria, actinomycetes, from the group of coli and E.coli was established, according to the Polish Norms. The qualitative evaluation included genus identification of bacteria from the family Enterobacteriaceae in compliance with commonly applied procedures. The highest bacterial count under study was found in October in the soil samples from under the cages (GI). Bacteria E. coli and Salmonella rods were recovered from the soil (GI) and (GII) throughout the year, while Enterobacter spp. and Citrobacter spp. were isolated only from some GI samples. The highest average number of bacteria in fox feces was also established in the samples collected from under the cages at the turn of December and January. It was found that increasing relative humidity significantly decreased the count of all the bacteria studied in fox feces, whereas elevated air temperature contributed to declining numbers of psychrophilic bacteria and from the coli group. In the feces samples taken throughout the research period E. coli, Salmonella spp. and Shigella spp. bacteria occurred, while Klebsiella spp., Enterobacter spp. were isolated in single samples. The growth of all the studied bacteria was affected by relative humidity and sample moisture, whereas psychrophilic bacteria and from the coli group by air temperature. Microbial contamination of the environment is substantially influenced by the season of the year and the pertaining atmospheric conditions, as the largest bacterial load in soil and feces was determined in autumn and winter. The highest bacterial numbers occur in soil and feces collected from under the cages, which is associated with increased organic matter (feces and feed leftover) content and medium moisture optimal for bacteria. Therefore, it is recommended to undertake preventive measures within the sanitary-veterinary supervision aiming at improvement of the state of health of fur bearing animals.

W rejonie Pomorza Środkowego wykazano niedobór miedzi w glebie, paszach i surowicy krwi krów. Zawartość miedzi w organizmie krów zależała od ich stanu fizjologicznego oraz od poziomu tego pierwiastka w glebie i paszach, stosowanych w żywieniu. Deficyt miedzi w badanych stadach krów wymaga zwiększania jej podaży w dawkach pokarmowych.

The aim of the paper was to evaluate the copper content in soil, feeds and the blood serum of cows in the region of Central Pomerania. The research results obtained show that the shortage of copper occurred in the analysed region. The copper content in the blood serum of cows depended on their physiological state and the level of this element in the soil and feeds applied in cow nutrition. The successive lactation weeks and the lower content of copper in soil and feed reduced the concentration of this microelement in the blood serum of cows. The copper deficiency in the studied cow herds should be reduced by the addition to the feed rations of mineral supplements which include copper.

The studies aimed to evaluate the pathomorphological changes induced by various management conditions in arctic foxes. Healthy pups aged about eight weeks were randomly assigned to two groups, 20 animals each. The foxes of the control group were housed on a farm, while the experimental group comprised of foxes raised in a confined space. Throughout the rearing period, air quality monitoring of the environment of both groups was performed. During the autumn slaughter (the experiment lasted for 7 months), sections of the liver, kidneys, lungs, ovaries, and uterus obtained from all the foxes were evaluated pathomorphologically. Pathological changes were observed in lung sections collected from the animals of the experimental group. During the air monitoring, higher concentrations of pollutants were identified in the experimental group environment.

The investigations were carried out on the grounds of data supplied by the State Sanitary Epidemiological Station in Lublin and focused on the occurrence of salmonelloses in humans from Lublin. The incidence analysis was made regarding age and sex groups. The percentage of each serovar of Salmonella rods as well as seasonality of salmonellose morbidity was also considered. In the years 1995-2005 2894 cases of salmonelloses were recorded in the city of Lublin, with the peak in 1995 (386). The morbidity rate varied according to year, seasonality, age and sex. The dominant serovars isolated in the diseased human organisms appeared to be S. Enteritidis as well as S. Hadar and S. Virchow. The highest morbidity rate was shown in the youngest age groups, i.e. from 0-4 years and generally higher percentages were recorded for women as opposed to men.

Clinically healthy Polish Holstein-Friesian calves were divided into two groups: a control group (12 individuals) and an experimental group (12 individuals). The experimental group calves received a mixture of 20% water herbal extracts prepared from Urtica dioica, Hb., Hypericum perforatum, Hb., Melissa officinalis, Fol., Chamomillae recutita Anth., Calendula officinalis, Flos, and Plantago lanceolata, Fol. The mixture was given from the 2nd to 14th week of their life. Control calves received no addition of herbal extracts to their diet. Red blood cell count, white blood cell count, haemoglobin concentration, haematocrit value, and mean corpuscular volume were determined in the 4th, 9th, and 14th week of the experiment. The beneficial effect of the herbal mixture on the level of the examined haematological parameters was demonstrated in all tested weeks. In the calves from experimental group, a significantly higher red blood cell count, haemoglobin concentration, and corpuscular volume, and lower white blood cell count were found. There were no statistically significant differences in the haematocrit values between both groups.

The aim of bacteriological examinations was to evaluate soil and manure taken from dairy farms at different times and sampling sites. The study was conducted from September to October. Soil samples were collected directly at the wall of the barn (GI) and at distances of 15 m (GII) and 45 m (GIII) from the livestock facilities. Manure was collected inside the building, at the entrance (KI) and at 1/4 (KII) and ½ (KIII) of its length. Air temperature, relative humidity and the moisture content of the samples were recorded at the sampling sites. The soil and manure samples were subjected to quantitative and qualitative bacteriological examinations conducted in accordance with Polish Standards. Statistical analysis of the results was performed by a one-way analysis of variance and Duncan’s multiple comparison test. The highest number of bacteria in the soil was found at the wall of the barn. Most mesophilic bacteria, actinomycetes, coliforms and E. coli were found in late April and early May, most psychrophilic microorganisms in June, and most proteolytic bacteria at the end of December and in early January. The microbiological contamination of the soil was low (coli titer ≤ 0.01), amounting to 0.001, and it was detected only at the wall of the barn. The qualitative study of soil revealed only E. coli bacteria. The highest number of microbes in manure was found in samples from the middle of the barn (KIII) taken at the end of April and at the beginning May. Out of the bacteria examined in this study, E. coli and Enterobacter spp. were found in manure samples throughout the study period. While analyzing the impact of selected parameters, such as microclimate and humidity, on manure samples tested for bacteria, a correlation was observed between the presence of all microbes and sample moisture. The bacterial contamination of soil and manure was the biggest during the spring period, which was probably due to climatic and microclimatic conditions. However, the contamination was negligible owing to the absence of pathogenic bacteria and a high soil index. This proved that proper zoohygienic conditions were maintained on the farm.

The aim of the present study was to determine the levels of selected hematological and immune indices in growers transported from the rearing unit to the fattening facility. Blood samples were analyzed for the white blood cell count and the leucogram profile. IgA, IgM, and IgG immunoglobulin contents as well as lysozyme concentration were determined in serum. The hematological evaluation indicated a significant impact of the transfer to the fattening unit on the WBC picture. In fatteners aged 11 weeks, an elevated level of neutrophils with a concomitant decline in lymphocyte numbers was observed. A higher concentration of dust as well as chemical and microbial contaminants determined in the air of the fattening unit also affected immunoglobulin concentration and lysozyme content.
