Opis:: Diets high in saturated fatty acids (SFAs) and n-6 polyunsaturated fatty acids (PUFAs) at the expense of n-3 PUFAs have been shown to increase the risk of cardiovascular disease, obesity and cancer. Animal fat is considered to be the major source of unhealthy saturated fats. However, beef fat has a high nutritional value owing to the presence of minerals, PUFAs, vitamins and selected protein fractions. The aim of this study was to determine the effect of fattening intensity on the fatty acid profile and mineral content of meat from Holstein-Friesian bulls. Holstein-Friesian bulls aged 11 to 19 months were fattened under semi-intensive (SI, 10 animals) and intensive (I, 10 animals) systems. The bulls were fed maize silage, rapeseed meal and premix ad libitum. The diets for group I animals were supplemented with 2.5 kg ground triticale provided in an automatic feeding station. Meat samples were collected from m. longissimus dorsi (MLD). The samples were mineralized and assayed for mineral content. Fat was extracted from each sample, and the fatty acid profile of beef was determined by gas chromatography. Dietary supplementation with ground triticale increased the average daily gains of bulls and carcass dressing percentage, and contributed to higher carcass conformation and fat cover scores. Beef was found to be a rich source of valuable mineral compounds. The meat of group I animals was characterized by higher potassium levels and lower sodium levels, which points to its higher nutritional value. Semi-intensive (SI) fattening increased PUFA concentrations and decreased the n-6/n-3 PUFA ratio in beef.

Opis:: Cow’s milk has the highest share of total milk production and consumption in the world, including Poland. Milk is the most important source of readily available minerals, particularly calcium, in the human diet. The chemical composition of milk varies depending on genetic, environmental and physiological factors. Changes in the composition and physicochemical properties of milk affect its biological value and processing suitability. The objective of this study was to determine the effect of age of high-yielding Polish Holstein-Friesian (PHF) cows and lactation day on the calcium (Ca) and magnesium (Mg) content of milk. The average milk yield increased significantly during three consecutive lactations. The age of cows had a significant effect on the average Ca and Mg content of milk throughout lactation. Milk from younger cows had higher concentrations of the analyzed macronutrients. The concentrations of Ca and Mg in milk varied considerably depending on the stage of lactation. A substantial decrease in the milk Ca content was noted in the first stage of lactation. The calcium concentration in milk stabilized in the second month post partum, and it remained stable until the end of lactation. A decrease in the Mg content was noted until day 30 of lactation in milk from primiparous cows and cows in their second lactation. The oldest cows produced milk with the lowest Mg concentration, which resulted from a steady decrease in the milk Mg content until the fourth month of lactation. The Mg content of milk continued to increase from the fourth month until the end of lactation, regardless of a cow’s age. The Ca and Mg content of milk from the analyzed high-yielding cows was below the normal ranges (by approximately 24% and 6%, respectively). This is the reason why dairy products are often fortified with minerals.

Opis:: Beef has a high nutritional value owing to the presence of minerals, vitamins, polyunsaturated fatty acids (PUFA) and selected protein fractions. The objective of this study was to investigate the influence of calving and nursing on the fatty acid profile and the content of minerals and vitamins in the meat of crossbred (Limousine x Polish Holstein-Friesian) once-calved heifers in comparison with the meat of maiden heifers. At 15 months of age, once-calved heifers were inseminated with the semen of Limousine bulls. After calving and lactation, they were slaughtered. Meat samples were collected from m. longissimus dorsi (MLD). The fatty acid composition was determined with the use of a gas chromatograph. The content of 5 minerals (potassium, sodium, magnesium, zinc, iron) was determined by atomic absorption spectrometry. The content of vitamins A and E was determined by high-performance liquid chromatography. Gestation and nursing had a negligent effect on the content of functional components in the meat of oncecalved heifers, in comparison with the meat of heifers. The meat of heifers contained more vaccenic acid (TVA) (C 18:1 T10+11), arachidonic acid (AA) (C 20:4) and docosahexaenoic acid (DHA) (C 22:6), whereas the meat of once-calved heifers was more abundant in oleic acid, zinc, iron and vitamin E (P ≤ 0.01). Commercially crossbred heifers can be included in once-bred heifer production systems, which create a possibility of producing additional offspring plus higher body weight of heifers with no adverse effect on the functional properties.

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 objective of this study was to determine the effect of parity on the fatty acid profile of milk from 42 high-yielding cows, including 15 primiparous cows, 15 cows in their second lactation and 12 cows in their third lactation. Milk yield was evaluated and milk samples (462 in total) were collected between lactation days 6 and 60, at five-day intervals. The concentrations of 43 fatty acids were determined by gas chromatography in extracted fat. Cows in their third lactation were characterized by the highest milk yield – over 305-day lactation, they produced 13,160 kg of milk on average. Milk from primiparous cows had the most desirable fatty acid profile. It contained more (by ca. 12–17%) n-3 fatty acids and less (by 2.89–5.46%) fatty acids that adversely affect human health, compared with the other groups. Among essential fatty acids, differences were noted with respect to CLA (+9.5–9.8%), LNA (+12.7–18.7%) and DHA (+21–23%) to the advantage of the milk fat of primiparous cows.
Celem podjętych badań było określenie wpływu kolejnej laktacji na profil kwasów tłuszczowych tłuszczu mleka 42 wysokowydajnych krów: 15 pierwiastek, 15 w drugiej laktacji i 12 w trzeciej laktacji. Oceniano ich wydajność mleczną i od 6. do 60. dnia laktacji co pięć dni pobierano próbki mleka (łącznie 462), a następnie ekstrahowano tłuszcz i metodą chromatografii gazowej określano profil 43 kwasów tłuszczowych. Krowy po trzecim wycieleniu charakteryzowały się najwyższą wydajnością i wyprodukowały w laktacji 305-dniowej średnio 13 160 kg mleka. Pierwiastki produkowały natomiast mleko o najkorzystniejszym profilu kwasów tłuszczowych. Zawierało ono więcej o 12–17% kwasów z grupy n-3 oraz o 2,89–5,46% mniej kwasów o negatywnym oddziaływaniu na zdrowie człowieka. Spośród funkcjonalnych kwasów tłuszczowych różnice na korzyść tłuszczu mleka pierwiastek dotyczyły głównie CLA (+9,5–9,8%), LNA (+12,7–18,7%) i DHA (+21–23%).

Opis:: Wolce, w porównaniu z buhajkami, wolniej przyrastają i gorzej wykorzystują pasze, ale ich mięso zawiera więcej tłuszczu śródmięśniowego, jest jaśniejsze, bardziej kruche i charakteryzuje się większą wodochłonnością. Celem podjętych badań było określenie wpływu intensywności opasu oraz wieku zwierząt w momencie uboju na wartość rzeźną wolców mieszańców mięsnych uzyskanych z krzyżowania krów rasy polskiej holsztyńsko-fryzyjskiej z buhajami rasy limousine. Wolce opasano intensywnie do wieku 15 lub 18 miesięcy i półintensywnie do wieku 18 lub 21 miesięcy. Najcenniejsze tusze uzyskano z wolców opasanych intensywnie do wieku 18 miesięcy. Charakteryzowały się one najwyższą masą tuszy (321,1 kg) i dobrym jej uformowaniem (klasa R systemu EUROP) oraz największą masą pięciu najcenniejszych wyrębów (104,69 kg). Mięso tych zwierząt zawierało najwięcej tłuszczu śródmięśniowego (4,71 %), co odpowiada zmieniającym się preferencjom konsumentów. Ponadto wykazano, że opas wolców do wieku 21 miesięcy wiąże się ze wzrostem otłuszczenia tusz i znaczącym zmniejszeniem udziału najcenniejszych wyrębów w tuszy.
Steers, in comparison with bulls, grow slower and poorer covert feed, but their meat contains more intramuscular fat and its colour is lighter; it is more tender and characterized by a higher water-holding capacity. The objective of this research study was to determine the effect of fattening system and age at slaughter on the slaughter value of 46 crossbred beef steers produced by mating Polish Holstein-Friesian cows with Limousine bulls. The steers were fattened intensively to the age of 15 or 18 months, and semiintensively to the age of 18 or 21 months. The most valuable carcasses were produced from steers fattened intensively to the age of 18 months. They were characterized by the highest weight (321.1 kg), the best conformation (R class in the EUROP system), and the highest weight of their five most valuable cuts (104.69 kg). The meat of those animals had the highest intramuscular fat content (4.71%), and this fact meets the changing preferences of consumers. In addition, it was proved that the fattening of the steers to the age of 21 months was associated with an increase in the carcass fatness and with a significant decrease in the per cent content of the most valuable cuts from carcass.

Opis:: Grass silage is the basic component of diets for winter or year-round feeding of beef cattle in Central and Northern Europe, but its quality can vary considerably. The aim of this study was to determine whether the quality of silage influences the fattening performance of crossbred steers and whether higher intake of supplementary concentrate improves performance in steers fed silage of lower quality. The experiment was conducted on 52 crossbred steers with the initial body weight of 300 kg, produced by crossing Polish Holstein-Friesian dairy cows with Charolais, Limousin and Hereford bulls. The animals had ad libitum access to one of two types of grass silages (of higher and lower quality), and silage intake was recorded individually. Supplementary concentrate consisted of crimped triticale grain (785 g kg-1), rapeseed meal (190 g kg-1) and a mineral-vitamin premix for beef cattle (25 g kg-1). Concentrate was administered at two levels of 1.9 and 2.4 kg dry matter per day. The animals were housed in a free-stall system and feed intake was recorded individually. The fattening period lasted 65 days. Live weight gains were higher (P < 0.0001) in the group of steers fed high feed value grass silage than in the group administered low feed value grass silage. Steers fed silage supplemented with a higher level of concentrate were characterized by higher live weight gains (P < 0.0001) than those receiving silage with a lower level of concentrate. Average daily gains were similar in steers fed lower-quality silage with a higher level of concentrate and in those offered higher-quality silage with a lower level of concentrate (0.972 and 0.975 kg, respectively). It can be concluded that a comparable level of fattening performance can be achieved in steers fed low feed value silage supplemented with a higher amount of concentrate and in animals receiving high feed value silage supplemented with a lower amount of concentrate.

Opis:: The objective of efficient management in the public sector is first of all the rational use of limited resources that sector has. It is only possible when the performance of activities is entrusted to qualified managers specializing in the management of public sector organizations. It also depends on the implementation of modern management methods, for example procedures which enforce the efficient use of material (especially financial) resources: it is so-called management technology. Health protection and the management of public health care system units is one of the key elements of the state policy carried out as part of its constitutional duty regarding the common good. Within the system of managing these resources, territorial self-governments, particularly communal self-governments, are responsible for performing the activities which have the fundamental importance for citizens. The problem discussed in this article is first of all the clarity of planning in self-governmental independent health care centers and the availability of information on the management of public financial resources. It presents the results of research carried out in selected independent public health care centers in Warmia and Mazury region. Apart from drawing certain conclusions, the aim of the article was to propose changes in the financial management system of self-government health care units, especially planning which involves the performance budget execution system of the revenue and expenditure plan.

Opis:: Background. A commune local government is formed by inhabitants holding power through their representatives selected to the commune council and to positions of the executive body. Successful local growth is ensured by collaboration among all entities while fulfilling tasks specified by the state law and arising from inhabitants needs. In this paper an entity refers to inhabitants because this choice stems from the conviction that inhabitants co-participate in performing tasks and thus bear the consequences of management which, in the case of finance management, may lead to ill-considered expenditures and excessive indebtedness. Therefore, the research investigates inhabitant’s knowledge about financial economy, specifically the scale of the commune’s debt and related ramifications. Research aim. The aim of the studies conducted is to propose a model for finance man-agement in the commune local government, including management under conditions of debt bondage, where local potentials are used for acquiring larger financial resources from the commune local government’s members. Method. The research method used for the studies was a diagnostic survey. The survey rested on the method of questionnaire surveys and interview. The fragment of extensive empirical research carried out in all 118 communes across Warmia and Mazury Region was harnessed in the paper. Direct questionnaire surveys and interviews covered more than 5,000 persons, including councillors, officials, and principally inhabitants. 215 persons were randomly selected out of the whole base of questionnaires. Key finding. The research subject outlined reveals a primary research problem addressed in the studies. This refers to the knowledge among the commune local government’s members about the magnitude of debt in the commune, knowledge about individuals responsible for this indebtedness and, finally, implications of the debt for inhabitants.
