Opis:
This paper presents the physiological activity of the cerebral cortex in sheep in electroencephalographic findings. The study was performed to evaluate and improve understanding of brain monitoring methods in freely moving animals without the use of any anaesthetic methods during the acquisition stage. The aim of the study was to determine the physiological activity of the cerebral cortex in animals in a sheep model (using clinically healthy Polish Merino rams, aged 1 yr.) to determine its clinical EEG protocol. The EEG was registered using an in-lab EEG device as well as ambulatory systems (Holter EEG). The bioelectrical activity of the sheep cerebral cortex was recorded using gold disc and needle electrodes placed on experimentally determined locations on the scalp. The main finding of this study was the rhythmic EEG activity of the sheep brain in wakeful and conscious states (eyes open). The rhythm was bilaterally synchronous and determined a basic pattern in the registration of physiological activity of the cerebral cortex. The acquired rhythm may correspond to the theta rhythm in humans, which is a normal activity controlled by the hippocampus. This background activity comprised intermittent episodic slow waves and synchronous beta waves.

Opis:
Haemophilus parasuis belongs to opportunistic microorganisms of undefined virulence. The purpose of the studies was to compare suitability of PCR/RFLP in our modification and ERIC PCR for epidemiological study of domestic strains of H. parasuis. The results were evaluated taking into account two different aspects: suitability of the tests for isolating the highest possible number of clone groups and subjective evaluation of the method judged with respect to the following criteria: difficulty, availability of equipment and reagents as well as time and cost of the study. The results obtained in the present study show that the two methods used for typing of H. parasuis had high discriminatory power. Taking into account this parameter it can be concluded that ERIC PCR is more suitable than PCR/RFLP. This justifies the use of ERIC PCR for routine epidemiological analyses of mentioned pathogen. Taking into account the complexity of method used, ERIC-PCR based on random amplification of DNA, proved to be comparable to PCR/RFLP. The last mentioned technique is relatively less expensive and labour-consuming, especially when diagnostic PCR method is used for the epidemiological studies.

Opis:
The experimental material consisted of 42 sows divided into 3 feeding groups, each containing 14 sows fed complete compound feed varying in protein content. Protein and amino acid content of the feed fed to the control group was in compliance with Polish standards. Protein content in the experimental groups was reduced by 10% and 20%, respectively. At the same time, lysine, methionine, threonine and tryptophane content was supplemented to the level of the control group. All pregnant and lactating sows were fed individually. The condition of the sows was determined by measuring the thickness of backfat at the P2 position on days 30 and 105 of pregnancy and on day 25 of lactation. The data analyzed in the study included: the total number of piglets born, their body weight gain, milk composition, weaning-to-estrus interval and the farrowing rate. Protein content of the compound feed did not have a significant impact on the increment in backfat during pregnancy and losses during lactation. The sows fed compound feed with reduced protein content gave birth to 0.7 and 0.6 less piglets per litter than the control animals. However, due to lower losses, they bred 0.3 and 0.4 more piglets than the control sows. Average body weight of a piglet on day 21 was 0.5 kg lower in the experimental than in the control group. Dry matter, protein, fat and lactose content of the sow’s milk did not depend on protein content of the feed. The weaning-to-estrus interval in the experimental groups was one day longer than in the control group. The reproductive rate accounted for 86% and was comparable in all the groups.

Opis:
The aim of this study was to collect production data of Polish swine herds, with special emphasis on the production parameters in farrow to finish pig herds. Another goal was to determine differences in the production performance of swine herds with different sizes, various status with regard to biosecurity, and with different veterinary expenditure. For this purpose, questionnaire surveys were carried out in 96 polish farrow to finish pig herds. The data concerning production parameters (e.g. the number of pigs born per sow per year, litters per sow per year, pre- and post-weaning mortality), farm size (small, medium, large), management (all in-all out by room or building), veterinary expenditure (including medication) and the percentage of pigs under medical treatment, were collected. The data obtained in the present study indicate that in general, the efficiency of swine production in evaluated farms was relatively low. It was also found that in large swine farms the efficiency was better than that in small ones and that the proper biosecurity positively influenced the performance of the swine farms. However, only in 10.4% facilities, the biosecurity rules and methods, including the principle “all-in all-out”, were implemented and kept. It seems that inefficient swine production on the majority of Polish farms results from poor basic knowledge on pig production and understanding of fundamental economic rules of swine breeding.

Żelazny Most tailings pond
Opis:
The study was carried out on the Cu and Zn content of plant material (wheat grain, hay and potato tubers) and animal food products (cow’s milk, hen’s eggs and chicken meat) collected in the vicinity of the Żelazny Most waste treatment tailings pond (Lower Silesia, Poland). The samples for the study accomplished in 2016-2018 were collected from the places located in the nearest vicinity of the tailings pond (6 farms within a distance shorter than 4 km – zone I) and those located further away (6 farms within a distance from 4 to 10 km from the tailings pond – zone II). Copper and Zn concentrations were measured on a Varian Spectra AA220 Fast Sequential atomic absorption spectrophotmeter. The mean values of Cu noted in wheat grain harvested in the years under investigation ranged from 3.87 to 5.27 mg kg-1 DM, while the maximum value was 6.97 mg kg-1 DM. The highest accumulation of Cu and Zn was in hay (max. 10.10 and 99.04 mg kg-1 DM, respectively), while the lowest values were noted in milk and eggs. The zinc content of cow’s milk was found within the range from 2.64 to 4.01 mg kg-1 FM and the highest amount was 6.32 mg kg-1 FM. It was also found the mean Cu concentrations in poultry meat varied from 0.53 to 1.55 mg kg-1 FM and the maximum value was 3.50 mg kg-1 FM. No significant differences between zones I and II were observed (p≤0.05). The current results are comparable with those obtained in 2007 and 2013. With only a few exceptions, the biomonitoring studies did not show that the levels of the two metals in the biological material tested exceeded data reported in the Polish and international literature. Nowadays, there is no reason to consider the Żelazny Most tailings pond to be an toxicological threat to the natural and agricultural environment regarding Cu and Zn, but its periodic biomonitoring is necessary due to the chemical properties of these two elements and their potential effect on some environmental factors.

Opis:
W pracy przedstawiono wyniki badań próbek kompostu pobieranych w kolejnych fazach jego produkcji metodą pryzm napowietrzanych poprzez okresowe przerzucanie. Surowiec do kompostowania stanowiły odwodnione mechanicznie, częściowo ustabilizowane osady ściekowe z oczyszczalni ścieków komunalnych w Słupsku. Prezentowane wyniki są związane z tematem badawczym dotyczącym opracowania modelu matematycznego do oceny stabilności biologicznej kompostu w trakcie jego produkcji. Podstawowym celem modelowania numerycznego będzie stworzenie praktycznego narzędzia, umożliwiającego ocenę stabilności kompostu w czasie rzeczywistym (on-line), w oparciu o wartość prognozowanego wskaźnika AT-4. Monitorowane w trakcie kompostowania wskaźniki fizykochemiczne, stanowiące zmienne niezależne, to temperatura i stężenie tlenu w porach kompostu oraz sucha masa, substancja organiczna, OWO i azot ogólny.
The paper presents the results of analysis of compost samples collected in successive phases of compost production that relies on forming windows aerated by periodical shifting. Partially stabilized and mechanically dehydrated sludge from municipal sewage treatment plant in Slupsk was an essential raw material for composting. The presented results are related to the topic of research on the development of a mathematical model to assess the biological stability of compost during its production. The primary objective of the numerical modeling will be to create a practical tool for assessing the stability of compost in real time (on-line), based on the projected value of the indicator AT-4. Indicators treated as independent variables, monitored during the composting process, were temperature and oxygen concentration in the pores of compost, dry matter, organic matter, TOC and total nitrogen.

Opis:
Metoda oznaczenia zawartości substancji humusowych zastosowana w badaniach jest powszechnie używana do oznaczania stężeń wspomnianych związków w kompostach. Celem przeprowadzonych badań wstępnych pracy była ocena przydatności metody ekstrakcji za pomocą roztworu 0,5 M NaOH w materiałach pobranych z kolejnych faz kompostowania w celu określenia stopnia dojrzałości produktu. Próbki do badań pobrano z miejskiej oczyszczalni ścieków Przedsiębiorstwa „Wodociągi Słupsk” o średniodobowym przepływie docelowym wynoszącym około 28 200 m3 ścieków. Wsadem do kompostowania były odwodnione i przefermentowane osady ściekowe zmieszane ze słomą, korą i zrębkami. Uzyskane w badaniach wyniki w przypadku materiałów z fazy gorącej były obarczone dużym błędem. Na tej podstawie uznano, iż ekstrakcja substancji humusowych za pomocą roztworu NaOH może być metodą zalecaną jedynie dla dojrzałego produktu kompostowania.
The research method which was used in these studies is commonly used to determine concentrations of humic acids and humin acids in the soil. The aim of this study was to evaluate the usefulness of NaOH extraction method of materials taken from the first and last phase of composting. The samples were taken from wastewater treatment plant, which flow target was approximately 28 200 m 3 of sewage. The feedstock for composting was dehydrated and fermented sewage sludge mixed with straw, bark and wood chips. Five samples were tested; compost from the second week of composting - hot phase of composting (the sample 1), compost from the fifth week of composting (the sample 2) - end of the hot phase of composting, mature compost (the sample 3) - and of the maturing phase, compost prepared to further use, the dehydrated and fermented sewage sludge and the straw. The sample 1 contained 5.24 g/kg dry matter of the carbon of the humic acids and 3.38 g/kg dry matter of the carbon of the humin acids. The sample 2 contained 5.85 g/kg dry matter of the carbon of the humic acids and 3.52 g/kg dry matter of the carbon of the humin acids. The sample 3 contained 4.53 g/kg dry matter of the carbon of the humic acids and 3.11 g/ kg dry matter of the carbon of the humin acids. The sample 4 contained 6.34 g/kg dry matter of the carbon of the humic acids and 3.29 g/kg dry matter of the carbon of the humin acids. The sample 5 contained 6.56 g/kg dry matter of the carbon of the humic acids and 6.14 g/kg dry matter of the carbon of the humin acids. The humic substances, and also the lignin, the cellulose and the hemicellulose were extracted in this method. For this reason, the results of the materials taken from the hot stage may be obviously erroneous. Because of the fact that the mineralisation in the maturing phase of the composting was ended, it can be concluded, that the humic acids have dominated in the final compost. This indicates that the composting was successful. This results suggested, that the NaOH extraction of the humic substances may be recommended only for the mature product of composting - compost.
