This research was undertaken in order to obtain basic data for systematical pig management through analysis of management size of pig industry, wholesale price, the appearance ratio of carcass grade, consumption of total meat, the number of pigs imported and exported during about 10 years in Korea. These data collected from recent secondary raw data. The results obtained were abstracted as follows; 1. The number of raising pigs have tendency to increase gradually with about 7,060,000 pigs, while the number of farm household have tendency to gradually with 28,000 household on September, 1997. Accordingly, the farm sizes are charging with large scale of average of 257 pigs. 2. The farm price of alive pig at 100kg was high one with 176,000won in 1991. However, that of pig had been maintaining with slight value of 176,000won in 1996. The carcass price per 1kg is highest with average of 2,697won in 1991, but a little low with average of 2,485won in 1996. 3. The appearance ration by grade of pig carcass of A, B, C, D, and E was 18.2%, 30.5%, 27.2%, 20.0%, and 4.1%, respectively, on Oct. 1997. This result showed increment of grading with increment of year. 4. The wholesale price per 1kg by grade of pig carcass was 2,418won, the differences between A and E grade were 1,283won. Accordingly, the difference of the average of wholesale price per 1kg of pig carcass was approximately 257won. 5. The total of meat consumption per capital have been increasing with 28.80kg in 1996. The pork of meat consumption was 54 percentage. Accordingly, the pork has been important sources of meat, from now on. 6. The live pigs imported had been increased gradually up to 1995, however, decreased with 2,480 heads in 1996. These pigs imported have been mainly utilized as breeding animals for effective reproduction. 7. The pork imported has been showing rapid increment since establishment of WTO. In end of 1996, most porks were imported from Denmark, United States, United Kingdom, Canada, etc. 8. The pork exported showed increment of 158 percentage with 36,842ton in 1996 as compared with that in 1995.

This study was carried out to compare serum Ca, P, Fe, Mg levels in 20 chronic alcoholics and 30 normals. Analysis for serum Ca, P, Fe, Mg of the subjects were performed by fasting venous blood sampling before anthropometry. The mean systolic blood pressure in normals and chronic alcoholics were 113.0 ± 16.9 mmHg and 125.5 ±13.4mmHg respectively. The differences between the two groups was high significant ( P < 0.01 ). Average drinking period in alcoholics was 14.1±8.8 years, alcohol intake level was 24.8±6.0% in total calories. Serum calcium level in alcoholics( 10.21±1.82mg/dl)was higher than non alcoholics(8.86±0.47mg/dl) ( p < 0.01 ). Serum phosphorus and iron levels in alcoholics were higher than non alcoholics ( P< 0.05, P< 0.01 ) but serum magnesium level was lower in alcoholics than non alcoholics ( P < 0.001 ). Because alcoholics were lived in hospital in regular period, they could eat normal diet and abstinent, and then maybe I think that serum calcium, phosphorus, iron levels are higher in alcoholics than non alcoholics. We will make plan ahead about abstinence period influenced of mineral metabolism in alcoholics.

These experiments were carried out to investigate genetic polymorphisms of serum protein such as Albumin(Al) and Post-albumin(Pa), and to establish preservation plan of pure pedigree in Korean Native Goats(KNG). Their sera were collected and examined from the total of 74 KNG that raised in Tangjin district, Chungnam province. They were biochemically analyzed hby polyacrylamide gel(7.5%) electrophoresis (PAGE) in order to estimate the frequencies of genotypes and alleles existing on each trait locus. The results obtained were summarized as follows; 1. In the serum Albumin(Al) locus, the frequencies of genotypes for heterotype AB and homo type BB observed were 55.4% and 44.6%, respectively. While homotype AA was not found in the Al locus. The frequencies of gene in ?? and ?? were 0.723 and 0.277, respectively. Accordingly, the Al loci were assumed to be controlled by alleles like ?? and ??. 2. The frequencies of genotypes for homotype AA, BB, CC, and heterotype BC observed in post-albumin(Pa) locus were 9.5%, 51.3%, 10.8%, asnd 28.4%, respectively. Whereas, heterotype AB and AC were not detected in this Pa locus. The gene frequencies of ??, ??, and ?? were 0.095, 0.655, and 0.250, respectively. Therefore, the serum Pa loci were considered to be controlled by alleles like ??, ??, and ??. Key words: serum protein, PAGE, polymorphisms, locus, Al, Pa, gene, alleles, genotypes.

This research was undertaken in order to survey and analyze the current status of raising pigs. Furthermore, this paper was analyzed for getting a systematical improvement method by means of mating type of sow and boar. These data used were collected from recent secondary raw data. The results obtained from this research were abstracted as follows; 1. The number of raising pigs has tendency to increase gradually. On the other hand, the number of farm household has tendency to decrease gradually, therefore, the farm size are changing with large scale of average of 168.5 pigs. 2. The farm price of pig at alive 90kg was high one with 176,000won in 199. However, that of pig had been maintaining with low value of 155,000won in 1995. 3. The meat consumption per Capita was 27.75kg in 1995, the pork of total meat consumption was 54 percentage. Accordingly, the pork has been important resources of meat from now on. 4. The alive pigs imported had been increased gradually up to 3,696 heads of various breeds from different countries in 1995. Most of the animals imported alive have been utilized as breeding pigs. 5. The pork imported will show an increment according to establishing WTO. In end of 1995, the pork was imported from Denmark, United states, United kingdom, etc. 6. The international competive productivities have to be enhanced with the focus of economy of feedstuff cost and automatic machine. Therefore, economy of production cost in our farm will be required. 7. The pyramid pattern is required in population of pigs. So to speak, the nucleus herd shall be located in the top part of whole population. On the other hand, fattening commercial herd will be utilized for pork production with low location of whole population construction. 8. The excellent characteristics obtained from breeding sow and boar have to be maintained continually for improvement of breeding animals by means of public test station, and individual performance test station. 9. The hybrid will be obtained with the help of the mating types of prolific and superior animals. The three-way crossbreds have been used for fattening pig production. 10. Our farms have to secure the resources of breeding animal. And then, the study for improvement of prolific performances by utilizing Meishan dam from china will have to be continued. 11. The dam and sire with the negative genotype against stress susceptibilities have to be secured in order to produce genetically excellent pig. In addition, in order to get high equality meat, improvement of meat qualities has to be made through reconstruction of system feeding feedstuffs.

This research was undertaken in order to obtain the technological skill and good information on the feeding and raising of ostrich in Korea. Ostrich meat have been confirmed with edible meat in Korea since May, 2000. Ostrich meat contains reddish color, which is low calorie, high protein, and low fat. Most of people preferred to high protein meat contained plenty of nutrients except high fat including high cholesterol. We could utilize as edible and palatable foods such as pure meat, large egg, bone including bone extraction, and fur. Therefore, this animals could be called as an economical poultry. Ostrich husbandry, in the future, should be maintained with environmental agriculture. Without our desirable environment, we as well as animals also could eventually be destruction. The characteristics of raising ostrich as well as duck is the use of remains of extra food as a recycling. Especially, ostrich eats very well voraciously everything to be edible. Especially, ostrich, in poultry, grows very well in early stage in course of growth. On the other hand, it is difficult for most of farmer to market and to improve the strategy of high qualities of meat. Accordingly, many farmers who are raising ostrich try to improve and to enhance feeding skill as well as reproductive and genetic breeding. And then, we should establish logical and systematical marketing strategy through good management including improvement of meat.
