    Sea buckthorn is used in the world primarily for its high nutritional value and unique healing properties. It is a plant with a small climate and soil requirements. The study was conducted to determine changes mineral compounds in leaves of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), depending on the substrate type and the passage of time and assessment of the potential for sea buckthorn growth on saline and degraded soil. The determined the amounts of nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, sodium, molybdenum, chromium, lead, and cadmium. Shrubs of sea buckthorn (Hippophae rhamnoides L. ssp. rhamnoides), of which leaves were collected in June 2015, were located in four sites in Szczecin. The soils, on which sea buckthorn bushes grow are alkaline. The different sites of the growing shrubs of sea buckthorn (Hippophae rhamnoides L.) and the applied fertilization resulted in the differentiation of P, K, Ca, and Mg in leaves of the plant, but no change in N content was observed. Leaf samples collected a year earlier contained more N and P and less Ca and Mg. Leaves of sea buckthorn growing on the banks of the Odra river contained over ten times more Na, twice as much Fe, three times as much Mn as leaves of shrubs growing elsewhere. There was no difference in the amount of Mn in the leaves over the years, while those collected a year earlier contained more Fe. No presence of Mo, Pb, Cr and Cd was recorded in the leaves of sea buckthorn (Hippophae rhamnoides L.). Uptake of large amounts of Na, Ca, and Mg by sea buckthorn indicates the possibility of its growing on saline and degraded soils and the passage of time.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2023) Kazimierska, Katarzyna; Kępińska-Pacelik, Jagoda; Biel, Wioletta; West Pomeranian University of Technology in Szczecin, Department of Monogastric Animal Sciences, Szczecin, Poland; West Pomeranian University of Technology in Szczecin, Department of Monogastric Animal Sciences, Szczecin, Poland; West Pomeranian University of Technology in Szczecin, Department of Monogastric Animal Sciences, Szczecin, Poland
    Arthrospira (Arthrospira platensis, trade name spirulina) is commonly called “green meat” due to its high protein content (up to about 80% of dry matter). It is used in many countries as an additive in human and animal nutrition because of its high nutritional value. Arthrospira protein is of high quality due to the optimal composition of exogenous amino acids. Additionally, Arthrospira is a good source of fatty acids (including GLA, EPA, and DHA). It is used in formulas for complete and complementary pet foods. It can be a valuable source of complete protein for dogs. Its addition can significantly delay the process of lipid oxidation and reduce the number of undesirable microorganisms in the product. The pro-health properties of Arthrospira have been demonstrated in numerous scientific studies, including its effects on hypercholesterolemia, hyperglycemia, cardiovascular diseases, anemia, inflammatory diseases, cancer, and viral infections. The aim of this study was to characterize the nutritional values, health-promoting properties and the possibility of using Arthrospira as an additive in dog nutrition, based on a review of scientific literature.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Hury, Grzegorz; Stankowski, Sławomir; Makarewicz, Artur; Sobolewska, Magdalena; Biel, Wioletta; Opatowicz, Natalia; Department of Agronomy, West Pomerania University of Technology, Szczecin; Department of Agronomy, West Pomerania University of Technology, Szczecin; Department of Agronomy, Siedlce University of Natural Science and Humanities; Department of Agronomy, West Pomerania University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomerania University of Technology, Szczecin; Department of Agronomy, West Pomerania University of Technology, Szczecin
    The material for investigation were grain samples obtained from an experiment conducted in 2009–2011 at the Agricultural Experimental Station in Lipnik, near Szczecin. The study compared 3 factors: two systems of soil tillage (reduced and conventional), 4 nitrogen doses (0, 50, 100 and 150 kg · ha–1) and 3 winter spelt cultivars (‘Franckenkorn’, ‘Oberkulmer Rothkorn’, ‘STH 12’). The quality and farinograph traits of grain, flour and dough were estimated. Soil tillage systems – reduced and conventional – practically had not effect on grain and flour quality. Significant difference was observed only for gluten content. Nitrogen fertilization influenced significantly most of the quality traits. The optimal nitrogen level was 100 kg N · ha–1. Only for gluten index and gluten weakening the highest values have been observed at control variant without nitrogen fertilization. There was no interaction between cultivars and nitrogen fertilization except for gluten index. Mean values of this trait for cultivars ‘Oberkulmer Rothkorn’ and ‘Franckenkorn’ was on the same level at different nitrogen dose. Gluten index for cultivar ‘STH 12’ decreased significantly at higher doses. The results of farinograph analyses indicate that cultivar with the best baking quality was ‘Oberkulmer Rothkorn’, while with the worst quality – ‘Franckenkorn’.

    The effect of tillage system and nitrogen fertilization on nutritional value of winter spelt wheat cultivars
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Biel, Wioletta; Hury, Grzegorz; Jaroszewska, Anna; Sadkiewicz, Józef; Stankowski, Sławomir; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of the Food Technology, University of Science and Technology, Bydgoszcz; Department of the Food Technology, University of Science and Technology, Bydgoszcz
    The field experiment was carried out at the Agricultural Experimental Station of the West Pomeranian University of Technology in Szczecin, in Lipnik near Stargard Szczeciński in 2009−2011. The experimental factors consisted of: tillage systems (simplified and plow), selected cultivars and strains of spelt (‘Frankenkorn’, ‘Oberkulmer Rotkorn’, ‘STH 8’, ‘STH 11’, ‘STH 12’), and nitrogen fertilization levels (control – 0, 50, 100, 150 kg N . ha–1). Material for the study included samples of grain obtained as an average for the experimental combinations. In samples of grain were determined the basic chemical composition and fiber fractions. The research indicates that there are opportunities to shape the size of nutrient levels, which determines the use of spelt grain in the food industry by agronomic factors. Higher nitrogen fertilization significantly increased content of total protein (154 g . kg–1). Cultivar and strain factor had significant effect on the content of total protein (154 g . kg–1), crude fat (19.3 g . kg–1) and crude ash (20.8 g . kg–1) as well as neutral-detergent (114 g . kg–1) and acidic-detergent dietary (33.3 g . kg–1) fiber fractions.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Łysoń, Ewelina; Biel, Wioletta; Sobolewska, Magdalena; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin, Poland; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin, Poland; Department of Agronomy, West Pomeranian University of Technology, Szczecin, Poland
    Four winter wheat (Triticum aestivum L.) cultivars (Akteur, Adler, Discus, JB Asano) derived from organic and conventional production systems carried out in 2010–2011 at Gülzow (Germany) were evaluated. The wheat samples were analysed for content of dry mass, protein, fat, crude fibre, total carbohydrates and fibre fractions (NDF, ADF, ADL, HCEL, CEL). Grain originated from organic system had on average the crude protein 27% lower than that from conventional one (p < 0.05). It was found, that the winter wheat grain from organic system contained the higher level of total carbohydrates (p < 0.01) and crude fibre than that from conventional one (p < 0.05). The examined cultivars also significantly differed in the content of crude fiber and dietary fiber fractions. The conducted research did not allow an unequivocal determination of the crop production system that would have more beneficial influence on nutritious value of winter wheat grain.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2020) Kazimierska, Katarzyna; Biel, Wioletta; Department of Monogastric Animal Sciences, Division of Animal Nutrition and Food, West Pomeranian University of Technology in Szczecin, Poland; Department of Monogastric Animal Sciences, Division of Animal Nutrition and Food, West Pomeranian University of Technology in Szczecin, Poland
    Sporting dog owner should realize that proper nutrition is one of the most important factors influencing the sports results achieved by the dog. In addition to the increased demand for energy and basic nutrients, particular attention should be paid to the adequate supply of vitamins and minerals, as well as dietary supplements. Therefore, the aim of the study was to characterize the importance of minerals, vitamins and functional additives in the nutrition of sporting dogs. The significant elements in the sporting dogs nutrition are calcium, phosphorus, potassium, sodium and magnesium. Micronutrients such as copper, iron, manganese, selenium and zinc are also very important. Of the vitamins in the sporting dogs nutrition, vitamins with antioxidant properties (vitamin E, vitamin C) are crucial, as well as vitamin D and B-group vitamins. Moreover, the diet of a sporting dog can also be enriched with functional additives that support the function of joints, muscles and circulatory system, as well as plants with an adaptogenic effect that improve the dog's immunity. Selecting the right amounts of individual additives so they fulfill their planned functions and are completely safe may be a problem. Since it should be remembered that both the deficiency and the excess of nutrients can be dangerous for the body.

    The field experiment was carried out in the years 2010–2013 at the West Pomeranian University of Technology Experimental Agricultural Station in Lipnik, near Stargard Szczeciński (Poland). The research included the determination of an impact of two weed control methods (mechanical and chemical) and three sowing densities on the yield of selected winter spelt and common wheat cultivars, the yield components and their physiological parameters. The application of a chemical herbicide did not significantly influence grain yielding in 2011 compared to a mechanical weed control method, and increased it in the years 2012 and 2013. An increase in sowing density from 300 to 500 grains per m2 increased the yielding, the number of ears and at the same time, decreased the grain number in an ear. The mass of 1000 grains was similar regardless of sowing density. The highest mean yields in the three years were observed in common wheat Tonacja, lower in spelt cultivars of Plant Breeding Strzelce and the lowest in Oberkulmer Rotkorn spelt cultivar. The responses of spelt various cultivars to different weed control methods and to various sowing densities were similar.

    The influence of soil differentiation on chemical composition of sea buckthorn (Hippophaë rhamnoides L.) leaves as feed material
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2016) Jaroszewska, Anna; Biel, Wioletta; Jurgiel-Małecka, Grażyna; Grajkowski, Józef; Gibczyńska, Marzena; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of General and Ecological Chemistry, West Pomeranian University of Technology, Szczecin; Department of Agronomy, West Pomeranian University of Technology, Szczecin; Department of General and Ecological Chemistry, West Pomeranian University of Technology, Szczecin
    Due to the fact that sea buckthorn leaves could be a supplement to animal feed and food products, the present research aimed at determining the content of such elements as nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, lead, cadmium, nickel and copper in sea buckthorn leaves as well as establishing the relation between the elements content and soil composition. The leaf samples were collected in June 2014 from wild sea buckthorn shrubs (Hippophae rhamnoides L. ssp. rhamnoides) localised in four spots in Szczecin Poland. The data concerning the content of macronutrients (N, P, K, Ca, Mg) and micronutrients (Fe, Mn, Zn, Ni, Cu, Pb, Cd) in leaves of wild sea buckthorn (Hippophae rhamnoides L.) indicate that the leaves can be considered good animal feed material, comparable to grass and legumes. The fact that content of lead and cadmium in wild sea buckthorn leaves do not exceed the accepted norms for these elements is an another argument confirming its usefulness as an animal feed material.

    Feeding dogs is not a simple matter. Dogs are one of the most diverse animal species in the world. Thousands of years of evolution of the species of domestic dog (Canis lupus familiaris L.), have resulted in the fact that nowadays there are hundreds of dog breeds that differ not only in color, type of coat or character, but above all in size. No domestic animal has had a richer history of evolu tion in direct human contact than the domestic dog. Due to the growing awareness of the caregivers, the pet food market is changing dynamically. Foods are produced that are adapted to the dog’s age, lifestyle, physical activity and breed size. Despite this, often the animal’s diet is inadequate balanced. The caregivers make the mistake of choosing a food that is not adapted to the age and size of the dog. A common problem, for example, is to give puppy food to adult dogs of small breeds, although representatives of these breeds reach maturity more quickly than large breed dogs. Furthermore, the current nutritional guidelines do not provide recommended minimum and maximum amounts of any given nutrient based on the breed size of the dog. The purpose of this article is to characterize the most important nutrients, especially important in the nutrition of large and giant breed puppies.

    Nutritional problems of large and giant breed dogs. Part II. Adult dogs
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2023) Kępińska-Pacelik, Jagoda; Biel, Wioletta; Department of Monogastric Animal Sciences, Division of Animal Nutrition and Food, West Pomeranian University of Technology in Szczecin, Poland; Department of Monogastric Animal Sciences, Division of Animal Nutrition and Food, West Pomeranian University of Technology in Szczecin, Poland
    The subject of dog nutrition is gaining popularity due to the growing awareness of the caregivers. Although there are foods dedicated to dogs of different breeds available on the market, caregivers relatively rarely wonder what they really differ from each other and what significance it has for animals. Many dogs are fed the same food for extended periods of time. The product designated as a complete/maintenance food is, according to legal regulations, balanced in such a way that it can be the only source of food for the animal, without leading to nutrient deficiencies. A dog’s digestive tract has not changed for hundreds of years, but the physiology of dog nutrition depends on the size of the breed. Dogs of small, medium, large and giant breeds, despite the fact that they belong to one species, have different nutritional needs. These differences must be taken into account in order to meet the needs as best as possible. The smaller the dog, the greater the digestive volume, and vice versa. The diet of large and giant breed dogs should be enriched with functional additives supporting the work of the joints. This need results from the fact that representatives of large and giant breeds, due to their size and large body weight, are particularly exposed to excessive strain on the elbows and hips.

    One of the most popular methods of feeding dogs is giving them complete commercial feeds. When a decision is made to feed the dog with a dry food, selection of feed should not be made based on its price but in the first place on its quality. The research material consisted of 9 commercial maintenance feeds for adult dogs. The feeds tested were in granular form. Basic chemical composition in dry matter was determined for each feed (total protein, crude fiber, crude fat, crude ash and nitrogen-free extracts). Obtained results were compared with data provided by the manufacturers on labels of testes feeds. Metabolisable energy was calculated for each feed, based on the calculated chemical composition. All tested feeds satisfied minimal demand for total protein and crude fat. Three of them did not, however, meet minimum standard for adult dog feeds with respect to the level of metabolisable energy. Comparison of data on nutritional value provided by the manufacturers with results of own analyses showed that in several cases the manufacturers over- or underestimated content of particular nutrients. In 6 out of 9 feeds the manufacturers declared significantly higher content of protein. In one case the manufacturer declared significantly lower fat content that the one resulting from performed chemical analyses.

    Poultry meat is an important source of energy and nutrients, ensuring high quality of protein in the diet of dogs. The aim of the research was to determine the quality of broiler chicken meat. The experimental material of the paper were broiler chickens ROSS 308 reared in controlled environmental conditions up to 42 days of age. The content of basic ingredients and the amino acid profile were determined in breast and thigh muscles. Based on the research, it was found that the breast muscles contain more protein and less fat than the thigh muscles. The femoral muscles were characterized by a higher content of intramuscular fat, which influenced their higher energy value. Poultry meat has a high protein nutritional quality, is a good source of essential amino acids, which is beneficial in terms of nutrition.

    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2020) Tsyuk, Oleksiy; Marchenko, Dmutro; Shuvar, Ivan; Biel, Wioletta; Department of Agriculture and Herbology, National University of Life and Environmental Scienсes of Ukraine; Department of Agriculture and Herbology, National University of Life and Environmental Scienсes of Ukraine; Agriculture and Livestock Department, Lviv National Agrarian University, Dubliany, Ukraine; Department of Monogastric Animal Sciences, Division of Animal and Food, West Pomeranian University of Technology in Szczecin, Poland
    This work presents the results of the study of changes of the potential contamination of soybean agrophytocenosis in grain-row crop rotation by using different systems of farming and typical black soil tillage. It was established that in the upper 0–5 cm layer of soil there are on average 393–671 million pieces of weed seeds. which is 33.6–43.0% of the total number in the layer of soil 0–20 cm. It was established that the use of periodical moldboard and superficial basic soil tillage had no impact on reducing the potential contamination of typical black soil compared to the variant of differentiated tillage. During subsurface plowing the total number of seeds in the soil layer 0–20 cm increased by 13.5–25.8% compared to differentiated tillage. In the variants of ecological and biological farming systems the number of weed seeds in the layer 0–5 cm was 11.3–19.6% higher compared to the intensive farming system. Based on monitoring of the species composition of the weed seeds bank it was established that in the arable layer of the soil the largest share are annual dicotyledonous – 48–62%. annual monocotyledonous – 30.2–44.6%. perennial – 0.9–3.3% of the total number. It was proved that under the intensive system of farming the yield of soybean variety Silesia increased on average from 10.2 to 147% compared to the ecological and biological system of farming. During the biological system of farming soybean yield did not exceed 1.0–1.8 t/ha. Therefore. the industrial and ecological system of farming had the greatest impact on reducing the potential weediness of the soybean agrocenosis during the growing season. During the biological system of farming crop yields decrease due to the accumulation of weed seeds in the topsoil and formation of high actual weediness of the soybean agrocenosis.
