The experiment was performed on 48 crossbred ( Polish Landrace x Duroc) finishing pigs divided into three feeding groups: group I (control) – fed a cereal-soybean diet (diet 1), group II – fed a diet containing 15% oat bran and 3% soybean oil (diet 2), group III – fed a diet containing 30% oat bran and 5% soybean oil (diet 3). The pigs were kept in straw-litter pens (two animals, one gilt and one barrow, in each), and they were fed ad libitum from 70 to 110 kg live weight. A second-stage diet containing 30% oat bran and 5% soybean oil (group III) significantly decreased average daily weight gains and feed conversion efficiency, compared with control group I and group II. Different feeding had no significant effect on the lean meat and fat content of carcasses and the proximate chemical composition of meat. Diet supplementation with oat bran and soybean oil contributed to a significant increase in alpha-linolenic acid concentrations in the lipids extracted from m. longissimus dorsi (m.l.d.). The higher content of crude fiber and crude fat in diets resulted in a highly significant increase in HDL concentrations and a significant increase in triacylglycerol levels in the blood serum of pigs, yet it had no influence on total cholesterol levels in meat (m.l.d.) and liver samples.

The aim of this study was to determine the effect of mixed multi-component fertilizers on spring wheat yield, the content and uptake of macronutrients. A three-year field experiment (2005–2007) was carried out in a randomized block design at the Research and Experimental Station in Tomaszkowo, at the University of Warmia and Mazury in Olsztyn. The experiment comprised three fertilization treatments in four replications: control treatment (simple fertilizers), Amofosmag 3 and Amofosmag 4. The tested crop was spring wheat cv. Eta. The application of Amofosmag 4 significantly increased the yield of spring wheat grain and straw. The concentrations of the analyzed macronutrients in wheat were similar in all fertilization treatments, thus pointing to a comparable effect of the applied fertilizers. More pronounced differences in the chemical composition of wheat plants were observed between successive years of the study. The highest total uptake of nitrogen, phosphorus, calcium and magnesium by spring wheat was noted in plots fertilized with Amofosmag 4, which indicates that the nutrients contained in this product were more readily available to plants.

This study examined the effects of pressure treatment at 50 MPa / 0.5 h and 100 MPa / 0.5 h, at 18 ± 2oC, on the proteolytic activity of edam cheese subject to freezing after week 1, 4, 6 and 8 of ripening. The aim of the study was to test the utility of high pressures in cheese ripening under model conditions. Sensory and chemical analysis was performed on Edam cheeses after varied periods of ripening. The chemical analysis involved determination of active acidity of cheese, water and salt content and the content of different fractions of nitrogen compounds. Subsequently, the cheeses were frozen in a freezer (freezing rate 1 cm h –1 ) or in an alcohol bath (freezing rate 0.1 cm h –1 ), in order to speed up the lysis of starter cells. Extracts of frozen cheeses were subjected to high pressure treatment. Proteolytic activity of enzymes was determined by the Westhoff method in frozen, frozen and pressurised and control cheese samples after 1 and 2 weeks of incubation at 30 o C. The results of the sensory and chemical analysis displayed the normal course of the ripening process. The proteolytic activity of enzymes increased as the cheese ripened. No significant difference was found between the proteolytic activity in extracts from control cheese and in those from frozen and pressurised cheese. Freezing the cheese after 8 weeks of ripening lowered the activity of proteolytic enzymes. The proteolytic activity of enzymes in extracts from frozen cheeses after 8 weeks of ripening, pressurised at 50 MPa / 0.5 h was higher than in those subjected to the pressure of 100 MPa / 0.5 h. Pressure treatment of extracts from frozen cheeses at 50 MPa or 100 MPa did not result in expected acceleration of proteolysis.
本研究考察了50 MPa / 0.5 h和100 MPa / 0.5 h、18±20℃条件下的压力处理对成熟第1、4、6和8周后冷冻的毛豆奶酪蛋白水解活性的影响。这项研究的目的是测试在模型条件下高压在奶酪成熟中的效用。对不同成熟期的毛丹奶酪进行了感官和化学分析。化学分析包括测定干酪的活性酸度、水和盐的含量以及不同组分氮化合物的含量。随后，将奶酪冷冻在冷冻机中(冷冻速率为1 cm h -1)或酒精浴中(冷冻速率为0.1 cm h -1)，以加速发酵剂细胞的裂解。冷冻奶酪的提取物受到高压处理。采用Westhoff法测定冷冻、冷冻、加压和对照奶酪样品在30℃下孵育1周和2周后酶的蛋白水解活性，感官和化学分析结果显示了正常的成熟过程。酶的蛋白水解活性随着奶酪的成熟而增加。对照奶酪提取物的蛋白水解活性与冷冻和加压奶酪提取物的蛋白水解活性无显著差异。将成熟8周后的奶酪冷冻会降低蛋白质水解酶的活性。冷冻奶酪提取物在成熟8周后，在50 MPa / 0.5 h的压力下，酶的蛋白水解活性高于100 MPa / 0.5 h的压力处理。在50 MPa或100 MPa的压力处理下，冷冻奶酪提取物并没有导致预期的蛋白质水解加速。

This study was aimed at determining whether a pesticide tomb affects the ecological status of Lake Szeląg Wielki and to recognize how it affects phytocoenotic diversity of its vegetation. In addition, the results obtained will contribute to a database update and to the evaluation of the usability of a new Polish macrophytic method for the assessment of the ecological status of lakes. Analyses conducted in Lake Szeląg Wielki demonstrated that its ecological status was good, though the pesticide tomb had a modifying effect on the phytocoenotic diversity of aquatic and rush plants.

The purpose of the work was determination the area pollution influence on mineral compounds content in water of north and west part of Dejguny Lake. There was studied total-P, dissolved PO4 –3 (V), NH4 + ,N O 3 – ,N O 2 – , total-Mg, total-Fe, SO4 –2 and Cl– concentration in water. The most compounds content was in I class of water cleanness. The higher content of nitrate compounds was near the recreation area of Kronowo village and, ammonium and nitrate nitrogen, total phosphorus, ortho dissolved reactive phosphates and magnesium(II), near agricultural area depend on their content in water near the forested area. Moreover, in lake near agricultural area water side was higher content of sulphates(VI) in II class of water cleanness.

There was studied total-P, dissolved PO4 –3 (V), NH4 + ,N O 3 – ,N O 2 – , total-Mg, total-Fe, SO4 –2 and Cl– concentration in water. The most compounds content was in I class of water cleanness. The higher content of nitrate compounds was near the recreation area of Kronowo village and, ammonium and nitrate nitrogen, total phosphorus, ortho dissolved reactive phosphates and magnesium(II), near agricultural area depend on their content in water near the forested area. Moreover, in lake near agricultural area water side was higher content of sulphates(VI) in II class of water cleanness.","PeriodicalId":39364,"journal":{"name":"Polish Journal of Natural Sciences","volume":"25 1","pages":"369-375"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68932255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
