AbstractExhaust air treatment systems (EATS) are used in animal husbandry to reduce emissions. However, EATS are associated with high acquisition and operating costs. Therefore, a plant technology is being developed that integrates a recuperative heat exchanger into a biological air scrubber. The overall aim is to reduce total costs of livestock buildings with EATS by saving heating costs and to improve animal environment. In this study, a special pilot-plant on a small-scale, using clean exhaust air, was constructed to evaluate the heating performance on laboratory scale. Three assembly situations of the heat exchanger into trickle-bed reactor were part of a trial with two different defined air flow rates. In all three assembly situations, preheating of cold outside air was observed. The heating performance of the assembly situation with the sprayed heat exchanger arranged below showed an average of 4.4 kW at 1800 m3 h−1 (outside air temperature range 0.0–7.9 °C). This is up to 18% higher than the other two experimental setups. The heating performance of the pilot-plant is particularly influenced by the outside air temperature. Further research on the pilot-plant is required to test the system under field conditions.

Abstract The aim of the study was to assess the quality of shallow groundwater on the site pens and runoff from livestock manure heaps, in three selected farms involved in animal production and vegetable crops in the area of Plateau Proszowice. The analysis mainly included water from farm wells and effluents from manure. Additionally, water from drainage ditch running nearby farms was collected, before inflow of effluent (i.e. ditch water without manure effluent) and below inflow of effluent from heap of manure (i.e. ditch water containing manure effluent). Samples of the research material were collected from April 2012 to March 2014 at monthly intervals and analysed for the content of NO3-N, NH4-N, PO4-P, K, Na and Cl. Based on the obtained results it was found that water from the farm wells near the livestock buildings and from manure storage sites, was heavily polluted by the majority of these contaminants. The highest concentration of these pollutants, except for the NO3-N, was found in manure effluent – it exceeded a few dozen to a few hundred to any standards for water quality. There was also a significant deterioration in the quality of drainage ditch water because of the penetration of contaminants into ditch water from heaps of improperly stored manure. The water of the farm wells was characterized by excessive concentrations of NO3-N which disqualified it for drinking purposes.

When importing cattle from Hungary, Germany, Holland and Australia, many violations of veterinary rules for cattle management for the purpose of its reproduction, rearing and sale were noted. Pathogens of a number of infectious diseases penetrate livestock farms with the cattle purchased. Cases of infection of imported pedigree cattle with tuberculosis were noted. Scientists, together with practical experts of the Republic of Kazakhstan and the Russian Federation, conducted a series of surveys of livestock farms, where pedigree cattle was imported from abroad. The imortance of the veterinary-sanitary treatment of premises prior to the delivery of breeding livestock was highlighted. Feeding regime of such animals in the summer and winter periods was taken into account. Particular attention was paid to preventive diagnostic studies of imported livestock and local animals in contact with them. For more effective diagnosis, several diagnostic tests were used – from the usual intradermal tuberculin test with PPD tuberculin for mammals – to the palpebral and intravenous tuberculin tests as well as the “booster effect” method. In the diagnosis of tuberculosis, a special role was assigned to the results of autopsy and laboratory studies of biomaterial taken from animals killed for diagnostic purposes. In the complex of diagnostic studies for a final decision on the animal tuberculosis and a general epizootic assessment of the herd for animal tuberculosis, a diagnostic assessment of the intradermal fold of 5 mm and over was proposed. Comprehensive intravital diagnostic measures, post-mortem diagnostics of animals reacting to tuberculin, proper veterinary and sanitary measures in livestock buildings were carried out, contact of animals brought from abroad with local cattle and other domestic animals, as well as poultry, was excluded. Comprehensive measures can reliably prevent and diagnose cases of tuberculosis both in imported and local livestock when placing it in specially prepared livestock buildings.
