A 371 agricultural households from 26 different communities in South Korea was subjected on a study of food taboos in January of 1966. To the pregnant women, those to whom a high protein diet is particurally important, as many as 14 different kinds of foods, mostly portein rich foods, were avoided to eat. It is believed that if duck is eaten while pregnant her baby may walk like a duck in later life. Some mother have a strong aversion to the rabbit meat that her unborn baby must be a harelip. It is feared to eat chicken, shark or carp by the pregnant mother for her baby may get a gooseflesh appearance, or fish scale-like skin in later life. It is thought that if mother eats soup made of meat borns, especially chicken bones, a disfigured baby may be born. Some area informed that if mother eats crab meat her future baby will always bubble. To the child-bearing mothers 13 different kinds of foods were avoided to eat. Some believe that if raddish kimchi, soybean curd, squash are eaten while dilivery that mother may get dental decay or to lose all her teeth. Other think that highly spiced raddish kimchi cause delivery difficult. To the lactating mothers 7 different items of foods were not recommended to eat. It is a common belief that eating green vegetables, especially fresh lettuce, are restricted that her baby may stool greenish. It is said that eating ginsen-chicken soup, or ginsen tea during lactating reduces breast milk secretion. To the weaning babies 7 different kinds of foods were prohibited to fee. Eggs are not eaten because mothers think her babies will start to talk very late. Eight different items of foods in cases of gastro-intestinal diseases, 5 items for liver disease, 7 items for high blood pressure as well as for paralysis were respectively restricted. It is said that meats including pork, beef, and chicken are neither desirable for the patients of high blood pressure nor those of paralysis. To the measles children 10 varieties of foods were restricted. Especially soybean products and meats were not encouraged to use for avoiding asecond attack of measles. For the common cold 8 different kinds of foods were aversed and men think that eating of soup of undria delays a recovery. For the tuberculosis 4 kinds of foods were prohibited to eat. It is said that wine, red pepper and ginsen will stimulate lung bleeding. Many mothers had a strong aversion to fermented shrimp and fish in case of style. and 5 different items of foods were restricted. In case of menstration not so many foods were restricted as other cases, but meat soup is not eaten in this condition in some areas. Majority of food taboos in Korean villages are neither based on tribal nor religious factors. But no one knows how, since what ages, from where, these food taboos have been transmitted and spread over the country. This survey found a great variety of food taboos, aversions, traditional beliefs and prohibitions latent unknown reseasons, or non-scientific conceptions, or completely different ideas from the modern medical aspect, or somewhat fallacious and superstitious beliefs. For the vascular disease contrasting approach were found between modern the oritical therapy and popular remedy among the rural populations who largely depend on the eastern medication. Further scientific study on either side should be done to lead the patient proper way. Many restricted foods such as rabbit, duck, chicken and fish are best resources of protein rich foods which are available in the village. Emphasis should be laid upon breaking down fallacious and supersititious food taboos through the extended nutrition education activities in order to improve food habit and good eating pattern for healthier and stronger generations of Korea.

The aim of this study was to determine the chemical traits of duck meats with different rearing periods(45 70 days). The content of protein was 21.3 and 19.61% in the breast and leg at 70 days post hatched, respectively. Group at 70 days showed high protein composition than those of 45 days group. The content of fat was slightly increased with the rearing periods. The composition of Ca, mineral compound, was not showed the difference between leg and breast meat. However, it was increased with the rearing periods. The composition of Fe was not significantly different in the breast meat. However, there was a significant increase in the leg (p<0.05). It was compared 14.6 ppm at 45 days group to 27.5 ppm at 70 days group. The content of methionine was significantly increased in the breasts due to the increasing rearing periods (p<0.05), but not in leg meat. There was no significant difference between parts, but glutamic acid content was significantly decreased along with the increasing rearing periods (p<0.05). The content of collagen at 70 days(0.77 g/100 g) was higher than those of 45 days(0.65 g/100 g). It was affected by the rearing periods In the wing-removed skit, it was 0.15 g increases at 70 rearing period group. The cholesterol content was significantly increased in the leg but not in the breast. With the rearing periods, it was significantly increased in the leg (p<0.05).

In order to obtain the basic information for new food product development from pheasant, wild duck(chhungdung), and Ogol fowl, which are called as special poultry, general components,fatty acid amino acid and minerals composition were analyzed. 1). The general compositions were 71.2-74.1% of water, 23.3-26.4% of protein, 1.0-2.4% fat, and 1.1-1.4% of ash in the pheasant, 73.8-76.4% of water, 18.6-19.6% of protein, 2.7-6.8% of fat, and 0.8-1.6% of ash in the wild duck, and 71.4-72.3% of water, 20.8-22.7% of protein, 1.9-6.3% of fat, and 1.0-1.2% of ash in the Ogol fowl, repectively. 2).In the pheasant and wild duck meat, the composition of unsaturated and saturated fatty acid were 60-64%,36-40%, respectively, and olec, palmitic, linolec, and stearic acid were most abundant in this order. But, in Ogol fowl, 72-76% and 24-28% were belong to the unsaturated fatty acid, respectively. 3). Amino acid contents in its order of relative amount were glutamic acid, alanine, aspatic acid, and glycine for the pheasant, glutamic acid, glycine, alanine, and aspatic acid for the wild duck, and lysine, glutamic acid, and aspatic acid for the Ogol fowl, repectively. 4).The mineral composition in the pheasant and wild duck were potassium, phosphorus, sodium, magnesium, and calcium, but in the Ogol fowl, potassium, sodium, magnesium, phosphorus, calcium were the most abundant in this order, repectively.

Foreign body (FB) ingestion is commonly seen in the ear nose and throat (ENT) field, with different presentations and sequelae. FBs can arrest in the upper aerodigestive tract or continue further down into either the airway tract to the bronchus or the digestive tract to the intestines. The pathway of an FB depends on the size and shape of the FB and how sharp its edges are. Since the 20th century, the use of disposable stainless-steel needles in the oral cavity has proven to be an effective and safe method for performing various intraoral procedures like dental infiltration or a root canal wash. Complications from their use are rare. Generally, dental needle breakages are caused by patients biting the needle, incorrect injection techniques, or inadequate preventative measures. The sudden movement of a patient during a procedure is one of the most common causes of breakage. Occasionally, needles are swallowed during dental procedures such as a root canal. Here, we report a case of a patient that swallowed a broken needle during a dental procedure. A few days later, the patient presented with neck pain, swelling, and a FB sensation. When the patient presented, she claimed that her symptoms had onset after consuming a meal containing duck meat. Initially, the patient was diagnosed as having ingested a duck bone. However, intraoperatively, the FB was discovered to be an injection needle that had migrated from the throat to the neck.

An experiment was conducted to evaluate feeding values of food and other organic wastes, and to determine their dietary effects on performance and carcass yield in ducks. A total of 156 meat type ducklings at the age of 25 days were housed in 12 pens and assigned to 4 treatments, in which the birds were fed for 21 days. One of 4 diets, commercial duck feed, raw food waste (RFW), fermented food waste(FFW) and mixture of 50% RFW and 50% FFW (R+FFW). Feed consumption was significantly higher (p＜0.05) in the RFW groups. Body weight gain showed no significant differences between the control and other treatments. The feed consumption ratio was significantly higher in the RFW groups (p＜0.05) than that of the other groups. Carcass yield was significantly higher in the R+FFW groups (p＜0.05) than the other groups. The weight of liver per live body weight showed significant differences among the treatment groups (p＜0.05). The length of intestine was significantly different from those of the treated groups(p＜0.05).

This study was conducted to investigate the cause of a new duck disease occured in southern part of Korea. A meat type duck farm located in Kangjin, Chonnam Province had experienced outbreaks of septicemic disease at around 20 days of age in nearly every batch of ducklings from early spring to early summer in 1989. Main symptoms of the birds were eye and nasal discharge, depression, inappetence, diarrhea and nervous signs such as tremor and ataxia. Some birds died suddenly without any signs. Mortality reached from 20% to 80% in severe cases. The autopsy findings of the affected ducklings revealed consistantly severe airsacculitis, fibropericarditis, perihepatitis and occasionaly enteritis and distended ureter with urate deposit. A rod shaped gram-negative bacterium was isolated purely from brain and liver of the diseased ducks by culturing the specimens on blood agar for 48 hours in candle jar. The isolate neither produced hemolysis nor grew on MacConKey Agar. It formed colony relatively slowly being recognizable at least 36 hours after culturing, reaching colony size of about 1mm in diameter at 48 hours culture. The colony looked iridescent under oblique light and had muddy odor. The isolate did not ferment carbohydrates tested but produced gelatinase, hippuricase and oxidase which were considered as characteristics of P anatipestifer. The isolate induced similar signs and lesions when infected experimentally into ducks of 3 to 38 days age via intraperitoneum or intratrachea. However it did not produce any clinical signs wen inoculated via intranasal route. It produced only mild signs in chicken just injected with a very large dose. The bacteria did not produce any signas or lesions in mice. It was concluded through biochemical and physiological tests and animal inoculation tests that the new disease was caused by P anatipestifer.

Apolipoprotein H (APOH) primarily engages in fat metabolism and inflammatory disease response. This study aimed to investigate the effects of APOH on fat synthesis in duck myoblasts (CS2s) by APOH overexpression and knockdown. CS2s overexpressing APOH showed enhanced triglyceride (TG) and cholesterol (CHOL) contents and elevated the mRNA and protein expression of AKT serine/threonine kinase 1 (AKT1), ELOVL fatty acid elongase 6 (ELOVL6), and acetyl-CoA carboxylase 1 (ACC1) while reducing the expression of protein kinase AMP-activated catalytic subunit alpha 1 (AMPK), peroxisome proliferator activated receptor gamma (PPARG), acyl-CoA synthetase long chain family member 1 (ACSL1), and lipoprotein lipase (LPL). The results showed that knockdown of APOH in CS2s reduced the content of TG and CHOL, reduced the expression of ACC1, ELOVL6, and AKT1, and increased the gene and protein expression of PPARG, LPL, ACSL1, and AMPK. Our results showed that APOH affected lipid deposition in myoblasts by inhibiting fatty acid beta-oxidation and promoting fatty acid biosynthesis by regulating the expression of the AKT/AMPK pathway. This study provides the necessary basic information for the role of APOH in fat accumulation in duck myoblasts for the first time and enables researchers to study the genes related to fat deposition in meat ducks in a new direction.

Recently, duck meat consumption has been rapidly increased because consumers recognized duck meat for healthy food. In relation to this, Korean duck industry need to develop Korean native duck (KND) breed for both conservation perspective and self-sufficient of the breeding stocks. In this study, 24 microsatellite (MS) markers were investigated for classification of KND and commercial duck (CD) breeds in the Korean market. Using these MS markers, the calculated number of alleles (K), expected heterozygosity (He) values and polymorphic information contents (PIC) were 1~16, 0~0.865 and 0~0.841, respectively. Also, the expected probability of identical values in random individuals (PI), random sib ($PI_{sib}$) and random half-sib ($PI_{half-sib}$) were estimated as $1.64{\times}10^{-16}$, $2.60{\times}10^{-7}$ and $1.30{\times}10^{-12}$, respectively. The results indicated that the expected probabilities of identity powers were enough for the individual identification. However, KND and CD breeds were not fully discriminated well using the 24 MS markers, which may CD and KND has shared same origin or crossbred. Therefore, further studies will be ultimately needed for developing a genetically pure line of KND breed even though the DNA markers used. Finally, these results will provide useful information for individual traceability system in ducks.

Chicken has been one of the most useful animals for life. They have been not only one of the most economical and adundant sources of valuable nutrients, but also the very good experimental animal to develop modern sciences. In Japan, eggs laid by the chickens have long been good sources of cash income for farmers and in many cases even for Samurais. Although nearly 50 millions of chickens were raised and they were of considerable importance in Japanese agricultre before the World War II, the industrialization or specializatin started after the War, Substantiallysince the 1960s. Among other spcies of poultry then chickens, ducks and Japanese quails are of some importane in Japan. Duck meat is often used in various cuisines at higher class restaurants and Japanese quail eggs are widely used. Hower those those species of commpared with chickens.
