The study focuses on the consumption of beverages in Czechoslovakia in the 1950s when it evaluated the consumption of alcoholic and non-alcoholic beverages in a broader perspective. At the same time, it analyzes the consumption of milk and hot drinks, especially coffee and tea. The text is based on professional scientific articles published on the pages of Výživa lidu (People's Nutrition) and Průmysl potravin (Food Industry) in the period 1951 - 1960. While milk consumption declined, beer consumption continued to grow. Alcohol consumption was clearly dominated by traditional beer which showed increase despite expert complaints. Wine was generally consumed very little. Other alcoholic beverages, with the exception of spirits, also grew, but not as much as the beer mentioned, promoted musts, juices and mineral water did not become a suitable alternative. Consumption of coffee and tea increased slightly, while in the period under review did not exceed pre-war consumption. In general, we can say that there were still differences between the Czech and Slovak parts of the Socialist Republic, where beer consumption predominated in the west and wine and spirits in the east.

Modern milking machines need some additional studies to meet the requirements as to milking equipment. An imperfect design of a teatcup results in an incomplete milking of cows. The availability of devices for milk flow stimulation promotes an increase in a cow milk yielding capacity. But here arises a problem of an un-controlled axial motion of a teatcup on a teat. As a result, a full milkflow is reduced, particularly at the final stages of milking. There is an effect of an increase in an inner diameter of a liner barrel, which causes that teatcups fall down. A scientific problem of the mitigation of some negative developments with the view to improve the efficiency of a teatcup arises. In a teatcup shell a liner is in a detended position during milking and resting periods. Thus, it under constant stretching. It results in a loss of elasticity irrespective of the material, as well as in reduction ofthe period of service maintenance. The use of a device for supporting a liner which is in a stretched state only during the milkflow, will result in an increase of a teatcup efficiency. The suggested automatic pneumatic mechanism releases a liner from the load during the resting period. The dependence of a tension force of a liner from the surface area of an annular membrane has been established. It has been proven that the membrane surface of 0.00065 m2 provides tension for a mechanism performance irrespective of operating vacuum pressure. The regression equation which connects geometrical parameters of an operating system with the efforts directed at the opening of a leading membrane has been received. A suitability of operation of using a pneumatic tightening device has been substantiated. An insignificant axial motion of a liner during a cycle of milking creates a stimulating effect. As a result, a completeness of miliking increases by 3-8%. [ABSTRACT FROM AUTHOR]

The oral food challenge remains the most reliable method for confirming or excluding food allergies. The most trustworthy variant is double-blind placebo-controlled food challenge (DBPCFC). In DBPCFC, both the patient and the investigator do not know which sample contains placebo and which is the active sample (verum). DBPCFC should be prepared in such a way that the concentration of the allergen tested in the food administered to the patient is as high as possible, while remaining imperceptible to the patient, and the same ingredients should be used in the active sample and placebo. In addition, meal ingredients, other than those tested, must not cause hypersensitivity symptoms in the patient and the taste, consistency, smell and colour of the food must make it impossible to identify which sample is active and which contains placebo. Self-preparation of recipes for active sample and placebo allows to blind virtually any allergen, but unfortunately it is often fraught with the error of insufficient concealment of the allergen. If the patient recognizes the content of a given food, then the DBPCFC conditions are not met. To avoid setbacks, reduce the preparation time of the sample and increase the likelihood of effective food blinding, one of the validated recipes for active sample and plecebo developed by the research teams can be used. The work presents general guidelines according to which allergens should be blinded. Strategies for the preparation of active and placebo sample are provided, as well as examples of validated recipes available in scientific publications. [ABSTRACT FROM AUTHOR]

Le mot désignant la première boisson de notre vie paraît peu original comme objet d’intérêt. Mais puisqu’il est des plus courants et connu de tous, nous présentons son fonctionnement dans le sens premier et dans d’autres acceptions dans le registre standard, dans la langue technique, dans le sens figuré ; nous observons les formations dérivées et composées et les expressions phraséologiques françaises et polonaises avec lait / mleko. Nous évoquons le lien entre le lait et le vin, présent uniquement en français et visible à travers quelques expressions. Nous essayons d’en tirer une image sémantique du mot et son emploi dans les expressions à partir des dictionnaires anciens et modernes français et polonais. Ce substantif concret, pouvant être compté parmi les universaux de la langue, ne présente pas de champ synonymique développé mais seulement quelques emplois métonymiques et métaphoriques qui nous paraissent néanmoins mériter une réflexion relative aux deux langues.

In order to examine the variability of production performance traits (lactation duration, milk yield for the whole lactation, milk yield in standard lactation, milk fat content, milk fat yield in standard lactation, protein content and yield in standard lactation), 954 cows, domestic and imported Simmental populations, were included in the study, with a total of 3641 completed lactations. Cows were located in the area of Toplica district, reared on individual farming households (tied system) and on the farm with intensive farming (free system). Based on the rearing method and origin, animals were divided into four groups: Group 1 (domestic animals reared by individual agricultural producers on individual farming households); Group 2 (imported animals reared by individual agricultural producers on individual farming households); Group 3 (domestic animals reared on the farm) and Group 4 (imported animals reared on the farm). The fourth group of studied cows showed the highest yield and protein content, while the cows of the third group had the longest lactation and the highest milk fat content. All production performance traits varied highly significantly (p=0.001) under the influence of the combined factor of housing/rearing method and origin. [ABSTRACT FROM AUTHOR]

There is gradually increasing body of informations, especially on web, that many diseases or not well being of people can be accounted to the either intolerance or allergy to some components of nutrition with special respect on gluten and cow milk. To enhance well being of people it is frequently recommended to eliminate these components from food. In majority of cases this elimination of nutritionally very significant components of our food is not evidenced. Their evidenceless elimination is significantly influencing the composition of food with numerous negative impacts on human health. Persons with true intolerance of gluten or cow milk or allergy to components of grains or milk could be identified properly using both clinical and laboratory investigations. Using the results of these investigations appropriate recommendations could be given to those patients with intolerance or allergy which can significantly improve the quality of life of these patients.

Background/Aim. Recently, there has been an increased interest in novel dietary antioxidants, including omega-3 fatty acids and bioactive proteins present in milk. The aim of this study was to examine potential antioxidant effects of four-weeks long fish-based and milk-based diets in female Wistar rats. Methods. Four-months old rats were divided into three groups receiving either: control diet, diet enriched with fish meal, or diet enriched with milk. The activities of antioxidant enzymes: glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT), and concentration of thiobarbituric acid reactive substances (TBARS) were determined in liver homogenates obtained at the end of the treatment period. Results. Statistically significant higher activities of GPx (3.52 ± 0.73 U/mg) and CAT (147.25 ± 15.93 U/mg) were detected in rats fed with fishbased meal in comparison with both the control (GPx: 1.93 ± 0.11 U/mg; CAT: 99.37 ± 10.03 U/mg) and the group fed with milk-based diet (GPx: 1.72 ± 0.52 U/mg; CAT: 104.18 ± 37.49 U/mg). Despite somewhat lower concentration of TBARS in the milk-treated group (0.88 ± 0.23 nmoL/mg), no significant differences were detected in comparison with other groups (the control group: 1.00 ± 0.08 nmoL/mg; the fish-based diet group: 1.13 ± 0.15 nmoL/mg). Conclusion. Diet enriched with fish could improve one's oxidative status by enhancing activities of antioxidant enzymes in the liver tissue. On the contrary, we failed to obtain results suggesting that milk could serve as a source of dietary antioxidants. [ABSTRACT FROM AUTHOR]

Objectives: To evaluate the iodine content of milk from market sources in Prague. Methods: Using the Sandell-Kolthoff reaction, iodine was analyzed in 26 different types of milk (full-fat, semi-skimmed, skimmed, fresh and long life) from seven retail chains operating in Prague. Milk was supplied by eight dairies identified by the CZ registration number. Results: The mean ± standard deviation (range) iodine concentration in milk samples was 234 ± 56 (125-364) μg/L. This result is close to the recommended limit of 200 μg/L. Semi-skimmed milk had a statistically insignificantly higher (p = 0.085) iodine content of 250 ± 52 μg/L compared to 217 ± 62 μg/L in whole milk. In contrast, the iodine concentration of 251 ± 57 μg/L in fresh milk was statistically significantly higher (p = 0.015) compared to 201 ± 41 μg/L in long life milk (p = 0.015). The iodine content in the milk from individual dairies with their collection areas differed significantly in a number of cases. Conclusions: The iodine concentrations of 234 ± 56 (125-364) μg/L found in market milk from the Prague area are close to the recommended iodine content in milk of 200 μg/L. [ABSTRACT FROM AUTHOR]

The aim of the study was to evaluate the energy-protein balance of feed rations for Montbeliarde cows on the basis of protein and urea content in their milk. In 2016 the herd numbered 319 cows, with mean yield 9,374 kg of milk. The cows were housed in a free-stall barn on deep litter and fed Total Mixed Rations (TMR), the composition of which was balanced according to Deutsche Landwirtschafts Gesellschaft (DLG) norms. The data used in the study were obtained from milk performance evaluations. It was found that only 22.9% of milk samples indicated that the cows were appropriately supplied with protein and energy. Excess protein (>3.6%) was observed in 41.4% of cases of optimum urea content, which suggests an energy surplus in the feed rations. In 3.9% of samples optimal urea content was accompanied by an insufficient protein level (25 kg) the tendencies were reversed, i.e. a higher percentage of samples were indicative of excessive protein (21.5-34.1%) and fewer suggested a deficit (1.6-6.7%). In the case of optimal protein and urea levels in the milk (group 5), the daily yield of the cows was 37 kg of milk. It contained 3.7% fat, 3.43% protein, 4.87% lactose and 12.6% dry matter. The cows producing milk with protein and energy levels indicating a deficiency of energy and an excess of protein in the feed rations were much more productive (group 3). Daily yield of cows whose milk had an insufficient level of urea (groups 1, 4 and 7) was much lower than in the case of the cows whose milk had too much urea (groups 3, 6 and 9). The lowest daily yield (19.5 kg), accompanied by the highest content of protein (4.02%) and dry matter (13.5%) and one of the highest levels of fat (4.16%), was noted in the group in which the protein and urea levels in the milk suggested a protein deficiency and an excess of energy in the feed. It can be concluded from the analysis that the results of milk performance evaluations regarding protein and urea levels in the milk should be given greater consideration in composing TMR feeds for various feeding groups.

W pracy analizie poddano nakłady pracy ogółem, powierzchnię użytków rolnych i wartość majątku trwałego w gospodarstwach specjalizujących się w chowie bydła mlecznego i prowadzących rachunkowość rolną FADN. Ponadto przedstawiono zmiany badanych cech dla gospodarstw w regionach FADN UE13. Z badań wynika, że powierzchnia UR w gospodarstwach prowadzących rachunkowość rolną FADN i zajmujących się chowem bydła mlecznego uległa zwiększeniu w badanym okresie. Podobne tendencje wzrostowe zaobserwowano w przypadku wartości majątku trwałego. Z badań wynika, że najwyższą wartość majątku trwałego odnotowano w 2014 roku w regionie FADN Pomorze i Mazury spośród czterech regionów Polski i była na poziomie 295,4 tys. EUR na gospodarstwo rolne specjalizujące się w chowie bydła mlecznego. Z kolei najniższy poziom wartości aktywów trwałych 46,3 tys. EUR wystąpił w 2006 roku w regionie FADN Małopolska i Pogórze.

The study included a total of 127 sheep milk samples from two different areas (Livno and Travnik) in summer feeding period (July, August and September). Fatty acids in milk were determined by gas chromatography (GC). The animals were marked with the appropriate number of ear tags on the basis of which we always took samples from the same animals through different periods. Fatty acids in milk were determined by gas chromatography and the following fatty acids composition: butyric acid, caproic acid, caprylic acid, capric acid, stearic acid, oleic acid, linoleic acid, arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, rumenic acid. The fatty acid content of sheep's milk in this study showed a tendency of variation, both within and between sampling areas, and characterized by its relatively high content of saturated fatty acid (SFA) during the period of harvest.

W pracy analizie poddano produkcję mleka w Polsce oraz czynniki ją determinujące na tle UE. Z analiz wynika, że produkcja mleka w Polsce po akcesji do UE wzrosła. Przyczyn tego zjawiska należy upatrywać w zmianach, jakie zaszły na rynku mleka i związane były z integracją europejską, systemem kwotowania i dostosowaniu do standardów unijnych w zakresie dobrostanu zwierząt. W analizie wyników badań wykorzystano metody tabelaryczne, graficzne i opisowe. W pracy przeprowadzono analizę statystyczną, z której wynika, że głównym czynnikiem decydującym o produkcji mleka w Polsce jest kurs euro-złoty.

Opracowanie przedstawia zmiany w produkcji mleka na świecie w latach 2000-2016. Przedstawiono zmiany ogółem oraz u największych producentów. W badanych latach produkcja mleka ogółem zwiększała się przeciętnie w roku o 15 mln ton, tj. w tempie 2,18%. W 2016 r. udział mleka krowiego w produkcji wynosił 82,6%, bawolego 13,9%, a mleka koziego, owczego i wielbłądziego wynosił 3,4%. Zmiany produkcji u największych producentów mleka były zróżnicowane co do kierunków i skali. Zróżnicowane były również kierunki zmian zużycia krajowego mleka. Na tej podstawie wyodrębniono trzy grupy krajów: o rosnących nadwyżkach rynkowych, o rosnących niedoborach rynkowych i o spadających nadwyżkach rynkowych mleka. W największej skali rosły nadwyżki rynkowe mleka w USA, Nowej Zelandii i krajach UE. Z tych krajów w 2016 r. pochodziło prawie 80% światowego eksportu mleka i jego produktów. W mniejszej skali nadwyżki rynkowe zwiększały się także w Argentynie i Turcji. Rosnące niedobory rynkowe mleka i jego produktów w największej skali występowały w Chinach i Rosji, a także w mniejszej skali w Meksyku, Brazylii i Pakistanie. Tendencja spadkowa w nadwyżkach rynkowych występowała w Australii, Ukrainie a także w Indiach. Polska charakteryzowała się rosnącymi nadwyżkami rynkowymi mleka i jego produktów, co powodowało wzrost eksportu. Na rynkach zagranicznych niezbędne było zagospodarowanie 2/3 przyrostu produkcji mleka w Polsce.

Acne vulgaris is one of the most common dermatoses among teenagers and young adults. Recent data from multi-centre studies indicate that the average prevalence of acne in the 15-24 age group is 58% in Europe and 42% in Poland. The aetiopathogenesis of acne is complex, involving inflammatory, immunological, genetic, hormonal and environmental factors (cosmetics, medications and the so-called Western pattern diet). Recent survey studies show that diet is commonly considered to be an acne-exacerbating factor. As many as 70% of respondents report introducing various dietary modifications to improve their skin condition. However, the link between diet and acne is controversial and studies to date are insufficient to formulate any evidence-based dietary guidelines for acne prevention and treatment. The best documented finding is the adverse effect of milk and foods with a high glycaemic index on the skin of patients with acne vulgaris. Although the role of chocolate (cocoa) consumption is controversial, the most recent randomized trials point towards its potential pathogenetic involvement in inducing acne exacerbation.
