Changes in fatty acid composition of pork rich in conjugated linoleic acid frying in different kind of fats
31-35Views:90In 1990ys antiatherogen, antioxidant and anticarcinogen effect of conjugated linolacids (CLA) was detected. From this reasons, our aims in this study were producing pork rich in CLA and studying the change of fatty acid composition of the produced pork cooked different kind of fats. For frying palm and sunflower oil and swine fat were used. Thigh was cutted for 100 g pieces. Meat pieces were fried at 160 °C for 1 and 8 minutes. Estimation of frying data it was determined that higher (0.13%) CLA content of pork was spoiled (60-70%) except in case of swine fat cooking,
because it is extremly sensitive for oxidation and heating. Swine fat has higher (0.09%) CLA content than plant oil, protecting the meat’s original CLA content. Cooking in swine fat did not have significant effect on fatty acid composition of meat. Low level of palmitic acid contect of sunflower oil (6.40%) decreased for half part of palmitic acid content of pork (24.13%) and it produced cooked meat with decreased oil acid content. Contrary of above, linoleic acid content of fried meat was increased in different folds as compared to crude pork. If it was fried in sunflower oil with high level linoleic acid increased (51.52%) the linoleic acid content in fried pork. The linoleic acid content of the high level CLA pork increased four times (48.59%) to the crude meat (16.59% and 12.32%). The high palmitic acid content of palm fat (41.54%) increased by 60% the palmitic acid content in fried pork, low stearic acid (4.44%) and linoleic acid content (10.56%) decreased the stearic and linoleic acid content of crude meat. -
Pricing in the pig production
25-29Views:72During my research work I will exame the state of pig production and the pigmeat trade in Hungary as well as in the EU. In this article I am looking at this branch, I plan to ask consumers about this topic. There is no point in importing pork if there is no market for it. The reality is that we like what is new, unusual and different. What lies behind this way of thinking?
Everybody agrees, consumer habits differ culturally, and this is true in European countries as well. I find it interesting to examine what parts of the pig are favoured the most by consumers in certain countries. As habits are different we can say that certain countries prefer pork chops while on other countries’ menus pork knuckles can be found. If we follow this train of thought it becomes apparent that due to these differences the price of pork varies from country to country.
According to figures, it is clear that certain countries are able to produce pork products cheaper. Since market works on the principle of supply and demand, those who offer their products cheaper will have a greater chance of remaining in this sector. Those on the other hand who can only produce their products at a higher price will eventually disappear from the market. The price is determined by the rate of the forint to the euro. Today’s strong forint is leading to the growth in imports. Recently, pork exports have fallen, but if the rate were to be 280 forints as it has been in the past, then it would be more favourable to sell pork products.
As Hungarian prices are high, meat processing companies are forced to import from neighbouring countries, which means a cheaper source of product. This has led to a decrease in the number of pig in Hungary meaning that we are now an overall importer of pork products rather than an exporter. -
The possibility of increasing at the conjugated linoleic acid content in pork
27-32Views:116The composition of fatty acids in food products is a significant factor in human health. Feeding can significantly influence the composition of fatty acids in the animal fat. We analysed the effect of feeding high CLA-content (conjugated linoleic acid) feed on the composition of fatty acids in pork. The animals were grouped according to the following: Group 1) feeding experimental, ghee-mixed feed for 76 days, Group 2) feeding the same feed, but only for 33 days, Group 3) feeding sunflower-oil-mixed feed for 76 days. Ghee contains CLA in high amount. The aim of our experiment is to analyse how the high CLA content influences the fatty acid content of pork. In the end of the fattening experiment the animals were slaughtered, then samples were taken from the loin, ham, abdomen and backfat from 10 animals from each group and analysed the fatty acid content. We found significant differences between the average fatty acid content of the samples. As an effect of feeding ghee-enriched feed, the CLA content significantly increased, compared to the control group. However, the linoleic acid and the arachidonic acid content were lower, and the proportion of fatty acids was also lower when feeding control feed.

Global and national economic importance of pig meat production
13-20Views:303The pork production has changed significant in recent decades. Pig production fell significantly due to the need to adapt to new animal welfare rules in the sector. Furthermore, change in the meat consumption habit had also a negative effect on pig meat production. Hungarian pig sector and meat industry are in a difficult situation. Due to the high feed prices, the average production cost of pig farming has often exceeded the producer prices in recent years, therefore an increase of pig population could not be realised yet. Pig market is characterised by cyclical fluctuations of supply and prices, furthermore the decreasing producer price occurred parallel with increasing feed prices.
Technology is also a critical fact in the Hungarian pig sector because there is a huge gap in the level of technology compared to that of competitive member states. With the development of production methods the efficiency of pork meat production can be improved in an environmentally friendly way. -
Some basic problems concerning world animal production at the beginning of the XXI century
77-80Views:111The author summarizes the main new challenges facing animal agriculture: growing GDP in many countries increasing animal protein demand, bioenergy industry as a new player using potential food or feedstuffs, increasing demand, Growing water and land scarcity, weaking the position of plant agriculture, feed production. Forecasts are summarized regarding the magnitude of meat consumption increases, and the possible plant biomass quantities required additionally in the next 20 years to cover the needs of food, feed and biofuel on a global scale.
Efficiencies of various animal production sectors, poultry, pork, beef, mutton meat, milk and eggs and their environmental footprints are compared, summarizing the most important research results concerning UK, USA, OECD evaluations. Intensive systems using highly productive plant and animal population will play an even more important role in the future especially in poultry, pig, milk and aquaculture production system being efficient users of resources (feed, water, land) and the environmental foot print is smaller per unit product. -
Challenges in the mangalitsa sector – present and future
147-153Views:120The Hungarian mangalitza pig sector has experienced numerous structural changes in the past few decades. The increased demand in the foreign markets for the mangalitza pork, changes in the domestic consumer perceptions have increase the number of sows and breeders. After the European Union’s accession started a significant growth in the sector, which was due to the target programme from the year of 2005 for the keeping of animals representing high genetic value, as the breed is indigenous. From 2008 continuous decline can be observed. The main reason for the decrease was the drastic growth of feed costs because of the drought damage in 2007, and the global economic crisis. Since 2010, a further period of supports has been in place, it extands the willingness to keep mangalitza pigs and the number of sows continuously increasing. On the basis of the average farm size (58 sows/farm) in 2011 it can be stated, that after our EU’s accession the medium-sized farms became stronger. To evaluate the geographic concentration of the mangalitza livestock it was analysed the data of sow number among the years of 2000 and 2011. The geographic concentration of mangalitza stock has a medium value over each year under the survey period, except the years of 2004–2007, when the values of Herfindahl-Hirschman index (HHI) have low degrees. Due to the subvention period of indigenous breeds it was established more mangalitza farms in different parts of Hungary. Despite of the growth since 2000, numerous problems are in the segment. The aim of the study is to find out the sectoral problems, which are completed with the objectives tree and draw up the main activities to solve the problems. After estimating the SWOT-matrix according to the methodology of the strategic analysis and the discussions with the secretary of National Association of Mangalitza Breeders is prepared the sectoral problem- and objectives tree. The core problem of the mangalitza sector is that the origin of mangalitza products are not certified in the domestic markets. The reason of it is that the breeders don’t request the certificates of fattening pigs, so it can appear not real mangalitza product on the markets as mangalitza. To solve the problems it is drawn up different suggestions in the objectives tree. This analysis is an useful tool for the decision makers in the mangalitza sector to evolve strategic plans on behalf of the efficient cooperations among chain actors.

The role of animal breeding with special regard to native pigs of food supply and rural development in Laos
149-154Views:243The present paper explored the influence of breeding native pigs on livelihood conditions and the contribution of native pigs to the rural development and rural poverty reduction in the rural areas of Lao PDR. Pig production plays an important role in meat supply for both urban and rural areas of Laos. It is clear that most of the pig products in the country come from smallholder pig farms, and more than 90 percent of those products are the native pigs mostly raised by farmers in remote areas. In general, livestock production distributed between 15–18 percent to GDP, while most of animal production still remains as the traditional methods. Rural development is always the first priority of the Laos government since its independence in 1975, however, the poverty rate in rural areas remained high at 23% in 2018. It might block the development goal of the government which will lead the country out of the least development status by 2020. The food security and malnutrition in the rural or mountainous areas are considered as the majority issue that both government and several international organizations have been thriving hard to overcome, which researchers showed that more than 45% of children under 5 years of age were stunted, and 28% of them were underweight. Inspired of more than 50 % of the households in the rural areas of Laos reported they consumed chicken and pork at least one day a week. While native pigs play an important role on meat supply, it also constituted around 9–14 % of annual income of the households in rural areas. Therefore, the increase the production of pigs and poultry is one option to promote the meat supply to households in the rural areas of Laos. This paper will be a pathway to guide and identify for the final decision to what experiment will be implemented on Lao native pig in Laos (2021–2023) to complete the comparative study on reproductive physiology and reproductive management methods of Hungarian and Lao Indigenous pig breed. Which found it still needs further afford to research and improve more about native pig performance for all areas of productive and quality management.
