Dietary fibre prevalence and its role in human nutrition
9-13Views:259The role of dietary fibre and its impact on health is increasing. It is worth noting that their beneficial effects on the body are becoming more widely known, but their consumption is still below the recommended daily intake from food. Dietary fibre, as a class of compounds, includes a mixture of plant carbohydrate polymers, both oligosaccharides and polysaccharides. Dietary fibre has been linked to a number of diseases, as its consumption can reduce the risk of cardiovascular disease and type 2 diabetes. They influence the composition of the bacteria present in the human gut. Consuming the right quantity and quality of dietary fibre can play a role in the prevention of certain types of cancer. Nowadays, it is common to produce various fibre-enriched foods, called functional foods, because of the beneficial effects they have previously had on the body. In the present work we want to give a general description of dietary fibre and its role in the body.

Examination of the main parameters of roe deer feed compound on two territories
13-16Views:112It is widespread that roe deer are very choosy. He needs this sorting because the micro organizms, which help the digestion of high fibre plants, are missing in his stomack, that is why they are mostly called „concentrate selectors” Hoffmann, 1985, 1988, 1989).
These animals should mostly eat easily digestable plants with high nutrition level (pulses, buds, sprouts and flowers), and they are able to do this sorting because of their small mouth size. In winter there is a lack of these plants, so the high selectivity occurs only when the feed is in abundance.
Examining the amount and quality of vegetation available on the habitat of roe deer we can identify the species which can satisfy their feed demand. It is known, that roe deer as other large ruminants, from the plant abundance prefer certain plants and plant parts while there are others which are avoided. The identification of the eaten species and the rate of their occurance in the feed is the first step to become acquainted with the interaction between animal and the surroundings. -
Leaf protein analyses in order to utilise the leaf shoot of artichoke
43-47Views:163The constat growth of the Earth’s population brings with itself a higher demand for food and protein not only in human nutrition but also for the feeding of livestock. Currently, the feed industry is mainly built onseed-based protein, wherethebaseplant is soybean, which is large lycovered by imports in Hungary, similar toother European countries. However, the long-term economically sustainable lifestock breeding demandschanges which has also worked out strategies. An alternative protein sources could be green leafy plants.
In current work the Jerusalem artichokes as an alternative source of protein was studied, compared to alfalfa as a valuable protein plant. Our results indicate that fiber fraction ofJerusalem artichoke shootswas 34 to 37% after pressing in the autumn period while alfalfa slightly lower values were obtained (30%). On the other hand extracted green leaf protein concentration was higher in alfalfa than in Jerusalem artichoke. Along with this higher protein content could be measured from the leaf protein concentration of alfalfa and almost each amino acids were more, as well comparing to Jerusalem artichoke.
Overall, the alfalfa proved to be advantageous as expected both in leaf protein extraction efficiency, both regarding the content of the protein in the Jerusalem artichoke. However, considering aminoacid composition and green biomass production, Jerusalem artichokecould be a promisingplant species asplant protein sourceinthefuture.

The effects of drought stress on soybean (Glycine max (L.) Merr.) growth, physiology and quality – Review
19-24Views:217Abiotic stresses are one of the most limiting factors inhibit plant's growth, leading to a serious production loss. Drought stress is one of the most destructive abiotic stresses and is still increasing year after year resulting in serious yield losses in many regions of the world,
consequently, affecting world’s food security for the increasing world population. Soybean is an important grain legume. It is one of the five major crops in the world, an essential source of oil, protein, macronutrients and minerals, and it is known as the main source of plant oil and protein. Harvested area of soybean is increasing globally year after year. However, soybean is the highest drought stress sensitive crop, the water deficit influences the physiology, production and seed composition of this crop. We introduce a review for literatures concerning the changes of the above traits of soybean exposed to drought stress, with past explanations for these changes. -
Volume of Paulownia Shan Tong (Paulownia fortunei × Paulownia tomentosa) plantation in Eastern Hungary: a case study
43-46Views:199Volume tables for tree plantations are not unknown in international practice. In many places, this is due to the uniqueness of the species or variety composition of the plantations and the cultivation technology used. In most cases, this is also justified by specific soil (ecological) conditions. In Hungary, publications on Paulownia have not yet included a volume table. This is the first one we are publishing, thus it can be considered as a gap-filler. The research was conducted in Monostorpályi, a 1.8 hectare, 8-year-old municipal plantation. 8 trees were selected randomly and their parameters were studied.

Effect of raised level α-linolenic fatty acid diet on broiler meat quality
29-33Views:106The aim of our investigation was to determine the effects of increased α-linolenic content in food on the colour, total pigment content, organoleptic characteristics and oxidative stability of poultry meat. The experiment was carried out with 1200 Ross-308 cock chicklings. Birds were fed three-phase diets, contained four different fat sources: lard, sunflower oil, flaxseed oil and soybean oil. According to the experiment, the different oil sources had no effect on growth performance, but the fatty acid composition of diets was reflected in the meat fatty acid profile. We could detect just slight change in colour in the treated meat, which was not caused by the decreased pigment content. The detected change in colour during the storage was not in relation to initial PUFA content. TBA level did not prove the accelerated lipid peroxidation which was expected in case of higher α-linolenic containing the meat. The data obtained in meat storage trial, could not prove clearly the negative effect of the higher α-linolenic content of the meat.

The examination of roe deer feeding on agricultural and woody habitats in winter

On the examined territories there was significant difference between the disembowelled body masses. The does which come from the hunt Nagyszénás weighed 4-5 kilos more than the does from the Csongrád territory. The main feed components were present in different rate in the samples of the territories, in the Nagyszénás samples grain, dicotyledonous herbacous plants were dominant, and were eaten more. The high level of grain in the feed result in better condition and larger body mass.
