Abstract. Spelt samples were derived from the plot trials carried out in 2008 at the Lipnik Experimental Station near Szczecin. The treatments were: 4 nitrogen fertilization rates: 0, 40, 80 and 120 kg N·ha^–1 and 2 spelt wheat varieties: Franckenkorn, Oberkulmer Rotkorn. Samples of spelt were analyzed for concentration of chemical composition, dietary fibre, minerals and amino acids. It was shown that spelt grain is rich in such nutritional ingredients. A statistically significantly higher content of protein and a lower value of crude fibre were observed in Oberkulmer Rotkorn cv. compared with Franckenkorn. The protein of spelt was characterized by a favorable amino acid composition of high quality protein which can be confirmed by the EAAI values. The first amino acid limiting the nutritive value of protein was lysine in all samples. Increased nitrogen treatment significantly decreased levels of lignin (by 1.6 g·kg^–1 DM) and ADF fraction (by 4.0 g·kg^–1 DM). The most beneficial content of essential amino acids was determined in Oberkulmer Rotkorn (32 g 16 g^–1 N).

Abstract. The aim of the present study was to evaluate dynamic changes in the concentration of albumin, and selected protein fractions with higher and lower molecular weight in comparison to albumin. The percentage of these fractions of the total blood plasma protein was also examined. The experiment was carried out on 7 calves during their first seven days of life. Additionally, changes with age of the albumin and high and low molecular weight protein concentration and percentage of the total blood plasma protein were also determined. During the first week of life mean albumin concentration in the blood plasma varied between 29.22–31.72 g · l^–1. The percentage of these fractions of the total blood plasma protein decreased from 38.14 to 29.43%. The concentration of high molecular weight fraction rose (from 8.43 to 14.47 g · l^–1). Average percentage of these proteins of the total protein varied between 10.71–13.22%. Both low molecular weight protein concentration (from 18.73 to 36.60 g · l^–1) and their percentage of the total protein (from 24.10 to 31.64%) increased during the first four days of life.

Abstract. The purpose of this study was to evaluate the wheat from the next two years, the harvest of wheat and other cereal products. The favorable comparison was the 2007 wheat harvest, as characterized by a higher content of crude protein and lower content of crude fiber, lignin and cellulose. The amino acid is limiting the nutritional value of wheat and wheat product was lysine and threonine. Nevertheless, the second limiting amino acid, according to the standard for man was threonine (2007) and isoleucine (2008). Furthermore, the protein of wheat in 2008 was characterized by a higher nutritional value compared to the 2007 wheat protein expressed by the rate of Oser (EAAI), respectively, in 2008, according to the MH (95.6) and EC (65.9) and in wheat in 2007MH (83.5) andWE (57.5), comparable to the petals (MH – 85.3 andWE – 64.9). The lowest nutritive value was characterized by a flour, while the highest germ.

Abstract. The aim of this study was to determine selenium content in selected tissues of roe deer (Capreolus capreolus) from Wielkopolska region and soil collected from the area of roe deer living. Research material included liver and kidney samples obtained from 23 roe deer (Capreolus capreolus). Animals were shot during the hunting season in summer 2009 in compliance with the hunting limits set. Soil samples (0–20 cm) were taken from 18 sampling sites in 2009. Selenium concentration in samples was determined spectrofluorimetrically using 2,3-diaminonaphtalene (DAN). Selenium concentration in soil ranged from 0.00–0.57 μg · g^–1 d.m. average 0.19±0.11 μg · g^–1 d.m. The mean Se content in livers and kidneys was 0.06 μg · g^–1 w.w. and 0,33 μg · g^–1 w.w., respectively. We observed positive statistically significant correlation (r = 0.7583; P = 0.00003) between these organs. Low selenium concentration in roe deer tissues and in soil indicates that examined area is deficient in selenium.
