Opis:: The present experiment was designed to demonstrate differences in the degree of fodder contamination with benzoquinones at various Tribolium confusum levels, the impact of infested feed on the beetle population and the impact of infested feed on the health status of rats. The feeding studies were done on female rats divided into 3 groups: a control group and two experimental groups. Experimental groups were fed with a fodder infested by 150 individuals of T. confusum per kg (group D1) and 300 individuals of T. confusum per kg (group D2). The insects were grown in the fodder for 5 months and the contaminated fodder was given to the laboratory animals for 8 weeks. After that period the rats were sacrificed, blood was drawn for morphological, biochemical and immunological analyses, as well as the samples of internal organs were taken for histopathology. Regardless of initial degree of infestation, after 5 months incubation period the content of benzoquinones in fodder reached the maximum level that reduced beetle population. The resulting concentration to benzoquinones had no effect upon feed intake nor growth of rate, whereas caused the presence of these substances in feces, urine and also in tissues which was indicated by pathological lesions observed in the study. The results obtained point to the possibility of the benzoquinones accumulation in the organisms of farm animals fed fodder containing pests.

Opis:: Humans and animals come into contact with various compounds in their natural environment. Most of the encountered substances are neutral, yet some may carry adverse health effects. The ingested food may be a source of harmful substances, including benzoquinones which, as shown by research results cited in this paper, demonstrate toxic, carcinogenic and enterotoxic activity. This group of compounds is inclusive of 2-methyl-1,4-benzoquinone (MBQ) and 2-ethyl-1,4-benzoquinone (EBQ), defensive secretions of the confused flour beetle (Tribolium confusum J. du V) and the red flour beetle (Tribolium castaneum Herbst). Benzoquinones have a carcinogenic effect, they are inhibitors of growth of various microorganisms, they produce a self-defense mechanism in threat situations and affect population aggregation. As noted by the referenced authors, the properties of benzoquinones have not been fully researched to this date.

Opis:: The aim of this study was to determine the effect of fish-based feed materials, as a source of readily available protein contained in fish broth and essential polyunsaturated fatty acids (PUFAs) found in fish oil, on the health of piglets and rearing results. The experiment was conducted on a commercial pig fattening farm. The study involved a total of 80 weaners with an approximate body weight of 15 kg. The experiment was carried out over a period of 40 days. Feed samples were subjected to laboratory analyses. Blood samples were collected from experimental group animals to determine serum biochemical and immunological parameters. The body weight gains of weaners, mortality rates and average feed intake per animal were calculated for the entire experimental period. The addition of fish broth and fish oil significantly improved the n3:n6 fatty acid ratio in diets. The presence of EPA and DHA in the experimental diet could have had a positive health effect on piglets, comparable with that exerted by therapeutic doses of zinc often administered to pigs of this age group. During the experiment, feed conversion ratio (FCR) gain was considerably reduced in the experimental group, with similar daily gains in the control and experimental group.

Opis:: Celem pracy było zbadanie wpływu dodatku mokrego młóta browarnianego na parametry jakościowe ekstrudatów kukurydzianych. Do badań zastosowano dwuślimakowy ekstruder laboratoryjny współbieżny Evolum 25 firmy Clextral z matrycą o średnicy dyszy wylotowej 4 mm. Uzyskane próbki ekstrudatu poddano analizie i oznaczono: gęstość (D), wskaźnik ekspansji radialnej (REI), wskaźniki wodochłonności (WAI) oraz rozpuszczalności w wodzie (WSI), aktywność wody (WA) oraz zawartość białka w produktach (PC). Stwierdzono, że zmiany parametrów procesu ekstruzji oraz zastosowane proporcje mieszanek kaszki kukurydzianej i młóta browarnianego miały istotny wpływ na zmiany parametrów jakościowych uzyskanych ekstrudatów. Zwiększenie udziału młóta w mieszance powodowało poprawę własności ekstrudatów, o czym świadczyły wzrost wskaźnika WAI i obniżenie wskaźnika WSI oraz wzrost zawartości białka.
The aim of the study was to investigate influence of wet brewer’s spent grain addition and process condition on the selected physical parameters of corn extrudates. The extrusion trials were performed with Clextral Evolum 25, co-rotating twinscrew extruder. The extruder was fitted with a circular die with a diameter of 4 mm. The ingredients used for extrudates preparation were: corn grid (12% moisture content) and wet brewery spent grain (WBSG) with 78% moisture. The extruded mixtures were prepared with 0%, 5%, 10%, 20% addition of WBSG. The fresh WBSG was received from Brewery in Łomża. The extrusion conditions were: feed rate of 5 kg·h–1, mixture moisture: 13, 16, 19,5, 26%, screw speed of 200, 250, 300 rpm, respectively. The barrel temperature profile were as: 60°C at feed entry, 80, 110, 110°C at the middle sections and 110°C at the die exit. During each experiment response parameters were constant. The extrudates which leaved the die were cut on approx. 3 cm long pieces and left to cool at room temperature to moisture stability (13%) until analyzed. One of the advantages of WBSG adding is that we can reduce energy consumption used to drying WBSG without quality loses. The quality of corn-brewery spent grain (BSG) extrudates were estimated by some parameters: density (D), radical expansion index (REI), water solubility index (WAI), water activity (WA) and protein content (PC). The results indicated that the density of extrudates increased with the increase of BSG content in the mixture and reached the highest value at 20% proportion BSG. Although the speed of extruder screws had a statistically significant effect on this parameter, changes were minor. Increasing the BSG level to 20%, increased the WAI value up to 600%, and decrease WSI index 4 times, from 40% down to 10%. It is not without significance for the growth of WAI seems the fiber contained in BSG influence. The fiber is able to store water inside of the extrudate particles. Fiber caused a reduction of starch degradation, which further with the increase insoluble fiber contain in the extrudate meant that the WSI value was decreased. Changes in the extrusion process parameters have also influences on changes other qualitative indicators, which are water activity and protein content of the extrudates. It was found that the water activity significantly increased with the increase in the BSG proportion in the mixture, while the impact of the extruder screws speed was low.
