Studies on the food-safety of pheasant and mallard, which belong to wild fowl as new meat resources. were carried out. The results were summarized as follows : 1. Food poisoning bacteria including Salmonella spp, was not detected from the inspections of small intestine, cecum, and rectum. 2. Parasite inspection tests on blood, feces, digestive organ, and thoracic organs were negative. 3. Antibiotic residues from the carcass muscle by simplified disk methods were not detected. 4. Seven different pesticide residue tests, such as DDT and BHT, on the muscle and liver were negative. 5. Four different kinds of toxic heavy metals such as Cd were much lower than the permissible concentration. Studies on the food safety tests and inspections from the pheasant and mallard were revealed that from taking this new food resources, the toxicities would be very low for the human health by the direct influences.

The objective of this study was to investigate the effects of hatch and sex on the body weight and shank length of growing pheasant. Least squares means of body weight at the age of 0, 4, 8, 12, 16 and 20 wks were 17.9, 96.0, 296.4, 563.4, 709.0 and 757.4 g for female, and 18.3, 104.4, 349.1, 728.5, 1001.4 and 1101.6 g for male, respectively. The hatch effect on body weight was significant at the age of 4, 8, 12 and 16 wks (P＜0.05), but the effects on shank length were significant at the age of birth and 8 wks only. There was no significant hatch effect on both the body weight and shank length at the age of 20 wks(P＞0.05). Least squares mean differences between female and male were significant(P＜0.01) over all wks of age except at hatch.

This study was carried out to estimate the heritability and genetic correlation for body weight, shank length and shank width at various wk of age in growing Korean pheasant. All the measurements were done from one day to 20 wk of age with 4 wk interval. The heritability estimates for body weight were in the range of 0.54~0.59 for male and of 0.49~0.81 for female from 4 to 20 wk of age. The heritability estimates of male and female were in the range of 0.38~0. 82 and 0.41~0.67 for shank length, and of 0.48~0.88 and 0.49~0.71 for shank width, respectively. Genetic and phenotypic correlation coefficients between the measurements at different ages in each trait of body weight, shank length and shank width were medium to high positive values. Because the estimates of heritabilities and genetic correlations were high, the genetic gain for body weight is expected by either a direct selection or an early selection based on the record of early growing stage.

We have developed an electromagnetic generator to bury in subcutaneous area or abdominal cavity of the birds. As we can't use a solar battery, it is extremely difficult to supply a power for subcutaneous implantation such as biosensors under the skin due to the darkness environment. We are aiming to test the antigen-antibody reaction to confirm an avian influenza. One solution is a very small generator with the electromagnetic induction coil. We attached the developed coil to chickens and pheasants and recorded the electric potential generated as the chicken walked and the pheasant flew. The electric potential generated with physical simulator is equal to or exceeds the 7 V peak-to-peak at maximum by 560/min of flapping of wings. Even if we account for the junction voltage of the diode (200 mV), efficient charging of the double-layer capacitor is possible with the voltage doubler rectifier. If we increase the voltage, other problems arise, including the high-voltage insulation of the double-layer capacitor. For this reason, we believe the power generated to be sufficient for subcutaneous area of birds. The efficiency, magnetic 2 mm in length and coil 15mm in length, if axial direction is rectified, the magnetic flux density given to the coil could calculated to 7.1 % and generated power average 0.47mW. The improvements in size and wire insulation are expected in the future.

This study was undertaken to investigate ultrastructural changes according to the radiosensitivity in the spermatogenic cells and Sertoli cell of the seminiferous tubules in Korean native pheasants. During spermatogenetic period, testes were collected from male adult Korean native pheasant and they were used as experimental and control birds. The experimental group was divided into a single-dose whole body irradiation group (400, 600, 800 and 1,000 rads) and a split-dose whole body irradiation groups(400/2, 600/2, 800/2 and 1,000/2 rads). The experimental birds were sacrificed at 24 and 72 hrs after irradiation and the control pheasants were sacrificed at the same time. Ultrastructural changes of Sertoli cells and spermatogonia were investigated by ultrathin section with electron microscope. The results obtained are summarized as follows; 1. The apoptosis was observed after 72 hrs group of the single-dose irradiation of 400 rads. 2. The cytoplasmic organelles of spermatogonia were severely damaged more than that of sertoli cell in 72 hours group of split-dose irradiation of 800 rads. 3. The cytoplasmic organelles of Sertoli cell were severely damaged except the nuclear membrane of Sertoli cells in 72 hrs group of split-dose irradiation of 1,000 rads.

A study was conducted to determine the effect of live weight of pheasants on egg production and egg quality characteristics. A total of 48 ring-necked pheasants were divided into control, heavy, middle and light BW groups. Live weights of the control were 1,187 g, 1,352.92 g for heavy group, 1,247.92 g for middle group and 1,003.33 g for light group. Egg production of groups were found as 47.32, 42.82, 45.79 and 46.51% respectively, in 10 weeks of period. There were no statistical differences on egg production among the groups. The effect of live weight on egg weight, shape index, specific gravity, shell weight, shell thickness, Haugh Unit, yolk weight and albumen weight were found statistically significant (p<0.05). The effect of live weight on albumen index, membrane weight and membrane thickness were found not important (p>0.05). On the other hand, other important factors to be effective on the egg quality of pheasants should be investigated. As a result of this study, live weight of pheasant hens is not an important factor to obtain high egg production in pheasants. But, body conformation of breeding materials should be in good conditions.

To investigate the response of egg production to the artificial light to induce early egg laying. and the changes of egg weight and egg shape during the egg laying cycle, 30 Korean ring-necked pullets and their 1,284 eggs layed under artificial light control were used in this study. The first egg was ohserved at the age of 31 wk, after 4 wk of stimulating light(16 hour light: 8 hour dark). Egg production rate during seven 2-wk periods from the begining of the first egg was 43.7% and a clear peak egg production(61.7%) was shown at the 4th 2-wk period. The effects of egg production period and pullet on the egg weight, egg length, egg width and egg shape index(width/length) were significant(P<0.01). In the egg production cycle. egg weight, egg length and egg width increased steadly with time. but the value of egg shape index increased up to the 3rd 2-wk period and then decreased. Repeatabilities from intraclass correlation for the egg weight, egg length. egg width and egg shape index were 0.61. 0.53, 0.49 and 0.48, respectively.

To analyze wedding feast dishes of royal prince (1651, 1696) of Choson Dynasty, studied Gare Dogam Euigwae. Historic book 'Gare Dogam Euigwae' discribed wedding feast dishes of king‘s Choson Dynasty. The results obtained from this study are as follows. Dishes were arranged in four kinds of table, the first one called the main table, the second the right side table, the third the left side table, the fourth the confronting side table. Dishes of main table were oil and honey pastry, and fruits (pine nuts, orange, dried persimmon, torreya nuts, dried chestnut, jujube). Dishes of the second table and the third table were oil and honey pastry, and small cake made of honey and rice with patterns pressed in it. Dishes of the fourth table were cooked vegetable (wild ginseng, platy-codon, radish, white gourd melon, ginger), dried slices of meat seasoned with spices (abalone, octopus, shark, pheasant), cooked meat (wild goose, fowl, egg, pheasant, abalone), and fried fish (roe deer, fish, duck, pigeon, sparrow). The main table (同牢大宴床) and the second table (右挾床) stand as a symbol for integrity. The third table (左挾床) symbolize longerity. The fourth table (面挾床) symbolize bearing many young and connubial felicity.

The purpose of this study were to analyze the consumption patterns of animal foods during the sixteenth century through Shamirok. There were eleven animal foods : beef, pork, chicken, pheasant, deer, roe, lamb, bear, fox, sparrow, and horse. The most frequently consumed were in the order of pheasant, doe, and chicken. There were 44 fish consumed, including flatfish, hairtail, mackerel, flounder, kumlin fish, bass, null fish, codfish, and red snapper, as well as four mollusks and six shellfish. Eggs and fish egg were also consumed. These foods were cooked as Tang(湯), Gui(灸), Po(脯), Hoe(膾), and Sookyook(熟肉), or processed after being dried or salted. The animal foods were mostly consumed as Po and Tang in daily eating and for formal dishes. Fish were mostly consumed as Jockgal or Shikhae. The foods were primarily acquired by donation from local officials or relatives ; secondly by independent poultry farming, fishing, or hunting, along with the production of grain and thirdly through barter with rice and textiles. Food were sometimes traded for profit, but such acts of trading while living ; as wartime refugees was a meager means for living.

To evaluate the storage characteristics of pheasant meat products, contents of aerobic, anaerobic and food poisoning bacteria as well as VBN were measured during storage at various temperatures. 1. During the storage Escherichia coli and food poisoning bacteria including Salmonella, Shigella and Staphylococcus were not detected from any of the pheasant meat products. 2. Total plate counts of aerobic and anaerobic bacteria increased with storage temperature, showing more than $10^6CFU/g$ of most pheasant meat products within 5~10 days of storage at $20^{\circ}C$ and $30^{\circ}C$. However, frank sausage, loin ham, pressed ham and salad showed less than $10^5CFU/g$ in 20~30 days of storage at $20^{\circ}C$. 3. When stored at $10^{\circ}C$, smoked product, electric roasted product and pressed ham showed the bacterial counts of more than $10^4CFU/g$ within 10 days of storage. Frank sausage, loin ham and salad, however, showed less than $10^3CFU/g$ in 10 days of storage at $10^{\circ}C$. 4. VBN contents of smoked product, electric roasted product and frank sausage exceeded edible limit of 20 mg%, showing more than 40 mg% and 80 mg% within 5 days and 10 days, respectively, of storage at $10^{\circ}C$. In contrast, loin ham, pressed ham and salad had the VBN of less than 20 mg% in 10 days of storage at $10^{\circ}C$. In summary, while pheasant meat products in general appear to be prone to microbial growth, loin ham and salad are thought to have a longer storage period than others, showing about 10 days of preservation at $10^{\circ}C$. Products other than loin ham and salad are suggested to be stored frozen or refrigerated at below $10^{\circ}C$.
