(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 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, 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 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.

(Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Łysoń, Ewelina; Biel, Wioletta; Cierniak, Maja; Kavetska, Katarzyna M.; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin; Laboratory of Biology and Ecology of Parasites, West Pomeranian University of Technology, Szczecin; Laboratory of Biology and Ecology of Parasites, West Pomeranian University of Technology, Szczecin
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.

Nutritional Value of Poultry Meat Utilized in the Dogs Diet
(Wydawnictwo Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Biel, Wioletta; Czerniawska-Piątkowska, Ewa; Department of Pig Breeding, Animal Nutrition and Food, West Pomeranian University of Technology, Szczecin, Poland; Department of Ruminant Science, West Pomeranian University of Technology, Szczecin, Poland
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.
