Opis:
Legumes should be considered as an important part of a healthy diet, because of both their nutritional value (high protein and low fat content) and functional properties (Trichopoulou et al. 2014). The functional components include carbohydrates, soluble fiber, vitamins and polyphenols. Epidemiological studies have shown a positive correlation between the consumption of legumes and a reduced risk of cardiovascular diseases, diabetes and certain types of cancer. In the past few years, phenolic compounds have attracted much attention owing to a large variety of biological actions, including anti-inflammatory effects, which they can produce (García-Lafuente et al. 2014). Chronic inflammation is a cause of many serious diseases, including cardiac disorders, allergy, DM 1, Alzheimer’s disease. In the anti-inflammatory food pyramid, pulses were placed at the base (Viveky et al. 2013). The aim of this study was to determine the content of amino acids, fatty acids, carbohydrates, macro- and micro-elements in the common legumes. The total protein content varied from 17.9 to 22.5 g 100 g-1. The mean content of fat varied from 1.1 to 2.0 g 100 g-1 and the soluble sugar content ranged from 4.3 to 7.9 g 100 g-1. The dominant amino acids were glutamic and aspartic acids. Methionine and cysteine composed the lowest percentage of all amino acids. Pulses were characterized by the presence of such fatty acids as a-linoleic, linoleic, oleic and palmitic acid. The mean content of iron varied from 3.3 to 5.3 g 100 g-1. The highest amount of this element was found in small bean, which was also characterized by the highest copper content. The highest amounts of zinc, calcium and magnesium were contained in dark red kidney bean. The analyzed pulses were distinguishd by high nutritive value. The identifed amino acids profile indicates sufficient quantity of lysine and shortage of sulphuric acids. The pulses also had a beneficial composition of fatty acids. The omega-6 to omega-3 ratio was between 1:2 and 4:1.

Opis:
This paper reviews the available literature about the botanical aspects and productivity, properties and applications of fenugreek. The source of this species are seeds and leaves. The high yield of fenugreek is influenced on the environmental and agricultural factors. The unique properties of this species are determined by variety, agricultural technology and habitat conditions, too. One of this species is a crop fenugreek (Trigonella foenum – graecum L.). Fenugreek belongs to the legume plants and is an environmentally friendly plant. The yields of plants depend on the genotype, climate, environmental conditions, cultivation practices, use of fertilizers, irrigation. The seeds are rich in biogenic element such as phosphorus, sulfur, magnesium, calcium but were less abundant in zinc, manganese and copper. Fenugreek seeds and leaves contain biologically active substances (protein, amino acids, biogenic elements, lipids and fatty acids), and they are used in traditional medicine, as functional food and in the cosmetics industry. In traditional medicine, fenugreek is used to prepare infusions, water and alcohol extracts, tinctures, meads, tonics with antidepressant and psychotonic properties, and muscle growth supplements. Fenugreek constitutes high-quality feed for dairy cattle which improves the health status of livestock. The findings presented in this review paper will be useful for consumers hoping to improve their health by incorporating healthy biogenic elements and fatty acids into their diets.

Opis:
Soybean is a member of pulses and probably the most valuable crop in world. Fertilization is one of the main economic and health-promoting factors in crop cultivation. Foliar application during the flowering stage using 4 phosphorus (P) doses (4, 6, 8 and 10 kg ha-1) as experiment-1 and 4 sulphur (S) doses (5, 10, 15 and 20 kg ha-1) as experiment-2 except control in the soybean variety Nova was performed in Konya, Turkey, in two years (2013 and 2014), in a randomized block design with 3 replications. The investigated nutrition parameters were protein (316.5-368.3 g kg-1), mineral components (in mg kg-1): P (6200-7350), K (8141-8302), Mg (951-1267), Ca (1083-1419), Fe (61.20-97.90), Cu (22.10-35.60), Zn (62.30-85.30), Mn (3.600-18.90) and fatty acids (in g kg-1): myristic (0.76-0.81), palmitic (109.3-115.1), stearic (41.32-50.12), oleic (229.4-266.7), linoleic (487.4-520.3), linolenic (70.58-85.32), arachidic (3.77-4.32), gadoleic (2.49-4.05), eicosadienoic (0.43-0.63), eicosatrienoic (3.76-4.11), lignoceric (1.33-1.46), nervonic (0.13-0.58) and docohexaenoic (0.24-0.68) acid. Statistical analysis showed significant levels for Mn (P applied at 5% level), myristic acid (S at 1% level), palmitic (P at 1% level), stearic (P at 1% level), linolenic (P at 1% level), nervonic (P at 5% level) and for docohexaenoic acid (P and S at 5% level). In general, the content of protein, Mg, Mn, palmitic, linoleic and linolenic acids showed an increasing tendency with the increased doses of phosphorus. Additionally, protein, Cu, Zn, palmitic, linolenic, gadoleic, eicosadienoic and docohexaenoic acids showed an increasing tendency with the increased doses of sulphur. Consequently, the response of soybean plants to foliar application of S and especially P during the flowering period entailed significant changes, especially in protein and essential fatty acids. The results can be used in nutritional medicine and by farmers, food companies, breeders, etc.

Opis:
In Poland, whey from the production of traditional mountain cheeses is used to make żentyca, one of several traditional products made from milk from Polish mountain sheep raised in the Polish Carpathian Mountains. Żentyca is produced by heating whey to 90°C, that is the temperature at which the whey proteins coagulate and, by being lighter, they form a tender skin on the surface of liquid heated in the cheese vat. This skin is removed from the surface and with a little of remaining whey it is poured as żentyca into a wooden barrel, where it undergoes fermentation by own natural microflora. Research on this unique product is very rare, so the purpose of our study was to evaluate the nutritional and dietary value of żentyca depending on the production date. The samples were taken in shepherd’s huts located along the “Oscypek Trail”, during the sheep grazing period in the Carpathian Mountains, at the beginning (May) and the end (September) of the period. The tested traditional product was characterized by high mean dry matter content and low pH. The study proved that the month in which żentyca was made had an impact on the product quality. Żentyca made from milk produced at the onset of the grazing period contained more protein, lactose and phosphorus but less fat than the product made in the late grazing period. The production month also had influence on percentages of individual protein fractions, and over 60% of the analysed amino acids had varied shares in the protein depending on the żentyca production date. It was found that żentyca is a product of high nutritional and dietary value which depends on the period of production.

Opis:
The aim of this study was to determine the content of basic nutrients as well as selected macroand micro-elements in the albumen and yolk of eggs produced at large-scale, commercial poultry production farms (10) as well as in organic (8) and courtyard farms (12). Ten eggs were randomly collected 3 times on each farm. For chemical analyses, the eggs were hard-boiled for 15 min and then stored at a temp. of 4°C until analyzed. The albumen and yolk of hard-boiled eggs were assessed for the content of dry matter, total protein, crude fat and crude ash, and for their energy value (net Atwater equivalents) as well as the concentrations of K, Na, Ca, Mg, P, Fe, Zn, Cu, Se and Mn. No differences were observed in the content of dry matter, total protein and crude ash. However, differences were demonstrated for the crude fat content, the highest (P < 0.05) level of which was found in eggs from the organic system (higher by 60% in albumen and by 17% in yolk than in the other eggs), which was accompanied by an increased energy value of these eggs. In all the analyzed eggs, similar concentrations were noted for Mg (egg white) and P (egg albumen and yolk). The albumen of eggs from the organic system was characterized by the highest (P < 0.05) content of K, Na, Ca, Zn, Se and Mn. In turn, the albumen of eggs from large-scale commercial poultry production farms contained the highest (P < 0.05) levels of Fe, Cu and Se. Yolks of the eggs from the organic system accumulated the highest (P < 0.05) levels of K, Na, Ca, Mg and Fe. In turn, the highest (P < 0.05) concentrations of Zn, Se and Mn were determined in yolks of the eggs produced in the homestead system, and that of Cu – in yolks of the eggs from large-scale commercial production. A highly positive correlation between concentrations of minerals in the albumen and yolk of the analyzed eggs was reported for the following pairs: K-Na, Se (0.998, 0.93); Na-Na (0.949); Ca-Mg, Mn (0.994, 0.951); Mg-Ca, Mn (0.986, 0.982); P-Ca, Mn (0.997, 0.961); Fe-K, Mg, P, Zn (0.999, 0.937, 0.988, 0.999); Zn-Ca, Mn (0.999, 0.945); Se-Cu (0.971) and Mn-Ca (0.902), whereas a negative correlation for: Ca-Fe, Cu (-0.974, -0.994); Mg-Cu (-0.921); P-Fe (-0.933); Zn-Fe (-0.912); Cu-Na (-0.951); Se-K, P, Zn (-0.960, -0.910, -0.962) and Mn-Se (-0.979).

Opis:
In Poland, the Welsh onion is still grown on a small scale only, while it is widespread and broadly used in the Far East. Owing to their mild, sweet flavour and delicate consistency, whole Welsh onion plants are used as ingredients in various dishes. Recent years have witnessed the growing popularity of Welsh onions in the Polish cuisine, particularly as a spring seasonal item. A two-factorial field experiment in a randomized block design with replications was performed in 2010 – 2012 in the Experimental Garden of the University of Warmia and Mazury in Olsztyn (NE Poland). Seeds of three Welsh onion cultivars, Long White Ishikura, Parade and Performer, were used. The aim of the study was to determine the effect of Polimag S fertilizer applied at different doses on the yield and the nutritional value of the edible parts of Welsh onion plants. The experimental factors were: (1) Welsh onion cultivars Long White Ishikura, Parade and Performer grown from seedlings, and (2) the application of a mixed fertilizer, Polimag S, at two doses of 0.72 t ha -1 and 1.44 t ha -1. The Welsh onion cultivars analyzed did not differ significantly with respect to yield. The total yield of Welsh onions did not increase significantly as the dose of Polimag S was increased from 0.72 t ha-1 to 1.44 t ha-1, which indicates that increased fertilizer use was economically unjustified. In all the years of the study, the lowest Welsh onion yield was obtained in the control treatments. Welsh onions cv. Performer had the highest dry matter content. Welsh onion cultivars and Polimag S had varied effects on the nitrate accumulation in the plants, but the maximum permissible nitrate levels were not exceeded. According to the current Regulation of the Minister of Health of 22 December 2004 the content of heavy metals in Welsh onion was lower than the normal range.

Opis:
The aim of the study was to assess the effect of different levels of Boswellia serrata supplementation in broiler chicken diet on the basic chemical composition and the Ca, Mg, Cu, Fe, and Zn content in breast and drumstick muscles. The analyses involved 200 Ross 308 chickens divided into 4 groups. The broiler chickens were fed diets containing 0 (C), 3 (BSR3), 4 (BSR4), and 5% (BSR5) of Boswellia serrata resin. In the chicken breast and drumstick muscles, the contents of dry mass, total protein, crude fat, and crude ash were determined and their energy value (net Atwater equivalents) was calculated. Additionally, the Ca, Mg, P, Fe, Zn, and Cu levels were determined. In the present study, there were no differences in the proportion of the breast and drumstick muscles in the carcass or in their dry mass, total protein, and crude ash content. The supplementation of broiler chicken diets with 3% (BSR3) and 4% (BSR4) of Boswellia serrata resin decreased quadratically (P < 0.05) the content of crude fat and the calorific value of the breast and drumstick muscles. An increased level of Ca (control vs. BSR diets, and linear, P < 0.05) in the breast muscles and P (control vs. BSR diets, and quadratic, P < 0.05) in the drumstick muscles was noted in the BSR3 and BSR4 chicken groups. The Mg content in the muscles of the examined broiler chickens remained at a similar level, irrespective of the amount of the supplement added. The BSR supplementation reduced Cu (in the breast and drumstick muscles) (P < 0.05) and Fe retention (in the drumstick muscles) (C vs. BSR, linear, P < 0.05). Further investigations are necessary to elucidate the mechanisms associated with the effect of Boswellia serrata on the level of microelement retention in muscles. In summary, Boswellia serrata can be considered a good feed additive with a positive impact on the dietary value of poultry meat.

Opis:
A field experiment was carried out in 2015-2016 on a private farm in the District of Zamość, Poland. The experimental field was located on soil with the textural composition of clayey silt, having slightly acid reaction, moderate organic matter content (19.4 g kg-1) and moderate content of available phosphorus, potassium and magnesium. The following factors were analysed: I) soybean cultivar: Amandine and Merlin; II) nitrogen fertilisation (kg ha-1): 1) N – 0; 2) N – 30 before sowing; 3) N – 30 at BBCH 73-75; 4) N – 60 (30 before sowing and 30 at BBCH 73-75). The aim of the study was to determine the influence of a cultivar and the level of nitrogen application on the content of basic nutrients in soybeans, and the yield of seeds, proteins and fat per ha of the crop. The research indicates that the soybean varieties Amandine and Merlin grown in the conditions of south-eastern Poland not only produce soybeans with high nutritional value, but also ensure high yields of seeds, protein and fat per ha. The Amandine soybeans had a significantly higher content of crude ash, crude protein and crude fibre than the Merlin cultivar. The highest level of crude protein was noted in the soybeans fertilised with nitrogen at a dose of 30 kg ha-1 at BBCH stage 73-75. This level of nitrogen application also resulted in the highest content of crude fat in the soybeans. The crude fat content was 202.3 g kg-1 in the Amandine soybeans and 217.2 g kg-1 in the seeds of the Merlin cultivar. The smallest proportion of monounsaturated fatty acid and the highest proportion of polyunsaturated fatty acid were noted in the seeds of the Amandine cultivar. The level of nitrogen fertilisation did not affect the fatty acid composition of the soybeans.

Opis:
Sida hermaphrodita as a crop plant could be used as raw material for the production of forage. The aim of this study was to evaluate the overall nutritional value of fresh and ensiled biomass of Sida hermaphrodita, harvested in the bud formation stage. The chemical and amino acid composition, fatty acid profile, concentrations of minerals and polyphenols of herbage and silage were determined. Additionally fermentation products were assessed in silage. Herbage contained crude protein (CP) of 182 g kg-1 dry matter (DM), neutral detergent fiber (NDF) of 375 g kg-1 DM and lignin content in NDF (L/NDF) was 8.88. Nitrogen fractions changed as a result of ensiling (P<0.010), non-protein nitrogen (NPN) from 274 g kg-1 total nitrogen (TN) in herbage to 683 g kg-1 TN in silage, and neutral detergent-insoluble nitrogen (NDIN) from 74.6 g kg-1 TN in herbage to 79.5 g kg-1 TN in silage. Silage was characterized by intensive lactic fermentation (114 g kg-1 DM) and pH of 4.30. It contained CP of 176 g kg-1 DM, NDF of 378 g kg-1 DM, and L/NDF (11.3) was higher than in the herbage. The CP of Sida hermaphrodita silage had a high content of essential amino acids (AAs) Lys, Thr, Val, Leu and Phe (3.98, 4.19, 4.55, 7.14 and 4.00 g 100 g-1 CP, respectively). Sida hermaphrodita silage was characterized by the highest K (6.262 g kg-1DM) content among macronutrients, and the highest content of Fe (40.88 mg kg-1 DM) and Mn (33.01 mg kg-1 DM) among micronutrients. Polyunsaturated fatty acids (PUFAs) predominated in the ether extract herbage and silage, and their proportion was three-fold and seven-fold higher than the proportion of monounsaturated fatty acids (MUFAs), respectively. Herbage had high quercetin content (652 µg g-1 DM), which decreased by 45% during the ensiling. Changes in the chemical composition suggest that this crop plant can be preserved by ensiling. The results of this study indicate that Sida hermaphrodita can be used for producing high-quality silage for ruminants.

Opis:
The test material originated from a field experiment conducted in 2010-2013, at the Experimental Farm in Felin (51°22’ N, 22°64’ E), which belongs to the University if Life Sciences in Lublin. A two-factor experiment was conducted in randomised blocks with 4 replicates. The chemical composition of grain of 4 wheat species was analysed: common wheat (Triticum aestivum ssp. aestivum L.) cv. Tonacja, durum wheat (Triticum durum Desf.) cv. Komnata, spelt (Triticum aestivum ssp. spelta (L.) Thell.) cv. Schwabenkorn, and einkorn wheat (Triticum monococcum L.) line PL 5003 (material acquired from the National Centre of the Plant Gene Pool), grown at different production technology intensity (medium and high level of cultivation technology). The analyses on wheat grain included the content of total protein, crude ash, crude fat, crude fibre, carbohydrates, phosphorus, potassium, magnesium, calcium, copper, iron, manganese and zinc. The results were subjected to an analysis of variance, while the differences were estimated by the Tukey’s test at the significance level of p = 0.05. In order to identify the correlations and relationships between selected grain quality traits, an analysis of multiple correlation was employed and coefficients of variation were calculated (CV, %). Einkorn wheat proved to have the highest levels of protein, fat, ash, phosphorus, potassium, magnesium, calcium, copper, zinc, iron and manganese. Among the remaining genotypes, common wheat had the highest levels of carbohydrates and fibre. Irrespective of the genotype, more intensive chemical weed and pest control and nitrogen fertilisation had a favourable effect on the content of protein and fat, while reducing the levels of fibre and carbohydrates. Most of the macroelements, except phosphorus, and all the microelements reached higher concentrations under the more intensive production technology. In terms of grain quality, the response of the genotypes to the intensification of production technology was only slightly varied.

Opis:
The study presents results of chemical analyses and the nutritional value of silages made from meadow plants exposed to foliar fertilization with silicon (Si doses 46.8 g Si ha–1 – variant I and 74.9 g Si ha–1 – variant II, preparation Optisil®), and data on the milk yield as well as the basic composition and quality of milk produced by cows fed with these silages. Standard methods (AOAC 2005) were used to determine the basic components of silages. pH and organic acids of silages were measured. The feeding trial was conducted on 30 Polish Holstein-Friesian dairy cows. The control group (C) was fed silage from non Si-fertilized meadow plants. The other two groups were fed with the fodder containing silages from Si-fertilized meadow, i.e. group I silage obtained from variant I (46.8 g Si) and group II silage obtained from variant II (74.9 g Si). The cows were fed with total mixed rations (TMR). The silages made from meadow plants accounted for about 26.3 kg of a daily total ration. The cows were also given hay, barley straw and concentrate feed (triticale, barley, and wheat). The share of papilionaceous plants increased and dicotyledonous plants decreased proportionally to silicon fertilization. The study showed no effects of the biostimulator on the crop yield. The silages made from silicon fertilized plants had a higher nutritional value. Feeding dairy cows with silages made from Si-fertilized plants improved their milk productivity. The total solids, protein and fat of milk were higher in the Si groups. The highest milk yield as well as the milk protein and fat content were achieved in the group of cows fed with the silage made from plants fertilized with the highest silicon preparation dose (group II). Milk contained lower total counts of microorganisms (BPC) and somatic cells (SCC). The best results in this area were noticed for milk produced by group I cows fed with variant I silage.

Opis:
The aim of this study was to determine the effect of different vegetable protein sources in complete finisher diets on the fattening performance of pigs, carcass quality and the nutritional value of pork. A feeding trial was performed on 72 finishing pigs divided into 3 experimental groups, which were fed complete finisher diets containing the following sources of vegetable protein: group S – genetically modified soybean meal, group P – low-tannin pea ‘Albatros’ and 00-rapeseed meal, group B - high-tannin faba bean ‘Nadwiślański’ and 00-rapeseed meal. Performance was evaluated based on daily gains and feed efficiency for the fattening period from 65 to 105 kg body weight. Defined indicators for slaughter carcasses, chemical composition and fatty acid profile of m. longissimus dorsi lumborum were assessed. Significant decrease (by 5.1%) in the average daily gain of pigs was observed in group B. Backfat thickness was also significantly higher in the carcasses of group B pigs, in comparison with group S. The intramuscular fat content of m. longissimus dorsi lumborum was significantly lower in group P than in the remaining groups. The replacement of genetically modified soybean meal with low-tannin pea ‘Albatros’ contributed to a decrease in the concentrations of saturated fatty acids (P < 0.05) and an increase in the levels of unsaturated fatty acids in the intramuscular fat of m. longissimus dorsi lumborum. A more desirable UFAs / SFAs ratio and lower total cholesterol was observed in the meat of pigs fed a diet containing mixtures of seed peas and faba bean.

Opis:
The aim of this study was to determine the effect of 20-year-long irrigation of permanent grasslands with potato starch and brewery wastewater on the botanical composition of sward, yield and nutritional value of hay. The experiment was conducted in the center for wastewater treatment and use in Mątwica-Kupiski (668 ha), which has been equipped with facilities for flood irrigation with wastewater since 1965. Potato starch and brewery effluents were mixed in a storage reservoir at a ratio of 1:0.4. Meadow sward was irrigated with wastewater in autumn and after the first harvest, at an annual dose of 200 – 300 mm. On average, wastewater contained (mg dm-3): N – 223, P – 48, K – 285, Ca – 80, Mg – 46, Na – 68. Before the first harvest in 1998, 2003, 2008, 2013 and 2018, the floristic composition of meadow sward was determined on an 11-degree scale by the Klapp method. Yield was determined in trial plots. Based on the percentage of dominant species (above 20% share of the sward), several floristic types of grassland communities were identified. Herbage samples were collected for detailed botanical and chemical analyses according to the floristic composition of the identified grassland communities. Chemical analyses of plant material were performed by standard methods. Longterm irrigation of meadow sward with wastewater contributed to the development of agronomically important plant communities, except for the Agropyron repens community in the western part of the research site. The yield of grassland irrigated with wastewater, regardless of a floristic type, was 2- to 3-fold higher than the yield of non-irrigated grassland. Hay harveste in wastewater-irrigated meadows met the crude fiber, ash and fat requirements of animals. The total protein content of hay remained within the recommended limits for high-quality fodder, except for the Alopecurus pratensis + Agropyron repens community.
