Recently, layer industry shows the decrease in the number of farm and increase in rearing scale in both Korea and Japan. Seventy percent of layer farms in Japan feed more than 50,000 birds per each farm but in Korea, only 19.3% of layer farms are feeding more than 30,000 birds which covers 59% of total chicken number. This tendeney will be more accellerated from now on. Brand egg Production in Japan is developed with the involvement of farmers, sailers feed companies and also the marketing structure of brand egg is well organised in between farmers and consumers. However in Korea, the marketing structure of brand egg is not well settled for this reason the egg price is often decided lower much price than regrnlar price by the intermediate dealers. Under this kind of tough situation, Korean layer farmers are stressed to develop new brand products such as functional egg, settle the sales and distribution network with the good cooperation of farmers, and distributers.

This study was performed to develop brand egg. Forty-four week-old Isa Brown were randomly assigned to 8 treatments and the number of hens were 300 per each group. Experimental period was about 10 weeks. The 8 treatment were as follows : astarich 2%(A), astarich 5%(B), chitch chitosan 2%(C), omega-3 powder 2%(D), pyrogreen 1%(E), greenpia 0.2%(F), hydrogenated soy oil 3%(G) and commercial layer feed(H). Eggs were collected at day 0, 7, 14, 40 and 70 for egg quality analyses. Laying rate was significantly higher in astarich groups(B, C) than ant other group, showing average of 88% of laying rate. In terms of egg factors, whole egg weight was the heaviest in control in control(A) and the lightest in omega-3 powder group(E), while egg yolk weight was the heaviest in astarich group(H). Haugh unit(HU) was the mean of 70 for all treatments and there were no significant differences among the treatments. Egg yolk color was significantly different among treatments during experimental period whenever yolk color was measured. At the day 7 after feeding of experimental diets, the yolk color of astarich 5% group(C) was darker and that of omega-3 powder group(E) lighter. The value of yolk color in astarich 5%(C) and 2%(B) was 14.2 and 12.5, respectively. But the rest of the groups did not show any differences in yolk color, showing mean of 11.5. In terms of shell thickness, shell tended to become thinner, but there were no defferences among treatments during experimental period. The mean value of shell thickness was 0.390mm. In conclusion, astarich groups may seem to produce the best possible quality of brand egg.

According to the importance(production ratio) of special brand eggs, poultry farma can be classified into four types(Types I to IV). A close relation can be observed between these types and farm scale. Special brand eggs used to be the speciality of small-scale, suburban poultry farms. Recently, however, the production of these eggs has been adopted by medium and large farms, too, and is increasing throughout Japan. In particular, small-scale farms specializing in these eggs have attained a high profit and take a characteristic management from as opposed to large-scale poultry farming that adopts the \"small profit and quick returns\" strategy. Because of this, the meaning of special brand egg production to farm management differs according to farm scale. For small poultry farmers, it means securing a high profitability and for medium and large producers, improving the corporate image or meeting the needs for assortment of retailers.

The features of special brand eggs are growing more and more diverse and it is hard to draw a clear distinction between these and ordinary (no-brand) eggs. Special brand eggs range from those with objectively recognizable characteristics to those given only an unsubstantial product image and price differentials are among them great, too. The relation between product features and prices is unclear. Special brand eggs are the commodity whose characteristics are the vaguest of all livestock products. Farm's brand eggs produce a high profitability to producers is they are directly sold to consumers, by, for example, home-delivery service. But if they are sold to supermarkets, etc., producer's (poultry farmer's) income becomes lower by the amount of distributors' margin, reducing the profitability substantially. Thus how to increase the ration of retailing is important for farmers to secure a high profit. The sales strategies of poultry are the combination of two elements, that is, new product development (product differentiation) and creation of new market. But it is difficult for special brand egg producers to develop products with clear characteristics (use value) distinct form ordinary eggs and so these producers depend on the factors of appearance, such as the color of egg shells and package. Special brand eggs manage to keep their marketable value by the combination of the few product features and product image. Thus NB eggs from feed producers have a great market-ability since they can take advantage of the power of patents and TV commercials. However, market differentiation affects profitability much more than product features and price gaps are very wide between directly sold and wholesaled eggs. The producers of special brand eggs have come to the turning point where they have to decide whether they will content with being the subcontractors for NB and PB eggs or they will continue to keep their independence in production and marketing.

Purpose - Eggs are nutritionally complete and one of the most popular natural foods. Moreover, the poultry industry is one of the important food industries. However, early industrialization of the poultry industry on its own did not lead to further development compared to other livestock industries. In this study, we investigate what factors influence consumers' behavior and how consumers' understanding of retail business affects their propensity to consume. This study is different from other studies as it analyzes how the brand names of manufacturers and distribution companies affect the purchasing characteristics or actual purchase behavior of consumers in order to suggest how these manufacturers and distribution companies can increase their competitiveness. Research design, data, methodology - This study conducted a survey of 250 randomly selected egg purchasers in discount stores from January to April 2013. Consumers' purchase tendencies were calculated through frequency analysis. This result was then utilized using cluster analysis to draw a conclusion about which purchase tendency influenced consumers buying three different brands of eggs or whether this tendency really affected consumers. As a result, the outcomes of Hypotheses 2 and 3 were not clear so we drew a conclusion with our analysis of Hypothesis 1. Results - While the outcomes of Hypotheses 2 and 3 did not clearly indicate whether purchasing tendencies affected consumers when buying eggs, our analysis of Hypothesis 1 indicated that consumers were affected by the quality of the eggs rather than exterior factors such as the brand name. Thus, we concluded that it is important to promote the excellence of the quality of the eggs. Usually firms buy eggs from farms and repackage them in order to sell them. In this sense, if consumers were aware of this egg production process, and eggs were fairly distributed to retailers, large retail PB businesses would also be able to enhance their competitiveness. Conclusions - The brand, packaging, retail outlet, and other external features influenced the purchase of eggs to a certain degree, while shelf life, grade of the eggs, cleanliness, and other intrinsic characteristics had more influence. In particular, shelf life was the most important factor influencing purchase. Consumers were influenced not only by intrinsic characteristics of the eggs but also by large-scale producers' brands. Consumers relied upon the brand despite reduced competition because they found it difficult to identify shelf life and/or cleanliness. Small businesses and/or large-scale retailers can remain competitive by maintaining the freshness and cleanliness of the eggs. Further studies need to investigate areas in which consumers' cognition of the product is poor and/or the purchase inclination with regard to less developed industries such as eggs. In this study, the greatest problem was that consumers did not consume in accordance with the current situation as consumers have preferred fresh and clean eggs for a long time compared to purchase decisions based on external brands and/or packaging.

This study was performed to investigate the freshness and nutritive components of eggs from Incheon area. The eggs of 64 brands collected from 7 hypermarkets and 6 brands collected from farms were examined to test the Haugh unit (HU), egg yolk index and specific gravity. HU and specific gravity were higher in farm eggs than in hypermarket eggs (P<0.05), and there was no difference in the egg yolk index. Among hypermarket eggs, HU and egg yolk index were higher in the graded eggs than in non-graded eggs (P<0.05), and specific gravity was not different between them. HU and egg yolk index of the eggs collected in March were higher than those in August (P<0.05). To monitor the bacterial contamination, total coliforms, total bacterial counts (TBC) and Salmonella enteritidis were examined. Salmonella enteritidis and total coliforms were not detected from all eggs. TBC of farm eggs were less than $10^1$ CFU/mL in all samples and TBC of hypermarket eggs were less than $10^1$ CFU/mL in 187 samples, $10^1{\sim}10^2$ CFU/mL in 3 samples and $10^3{\sim}10^4$ CFU/mL in 2 samples, respectively. Antimicrobial residues were not detected from all eggs tested. The vitamin E contents in the vitamin E enriched eggs from 6 brands hypermarket were 1.98~22.96 mg/yolk100 g ($14.04{\pm}8.81$ mg/yolk100g), and those of 5 brands among them were higher than the average of ordinary eggs. In one brand egg, vitamin E content was lower than the average of ordinary eggs. The vitamin E contents of ordinary eggs were 1.75~16.36 mg/yolk100 g (average $5.57{\pm}2.76$ mg/yolk100 g) and there were no price differences between vitamin E enriched eggs and ordinary eggs. In the contents of vitamin E, docosahexaenoic acid (DHA) and cholesterol, there were no significant differences according to the price. These results suggests that egg production, distribution, and management system should be improved for supplying fresh eggs to consumers at reasonable prices.

Livestock products like meat, milk and egg have been principal food sources for human beings since the historic periods of time. Nowadays consumption of these food items have been avoided due to its high contents of SFA, cholesterol and total fat which are major culprits of chronic adult diseases causing major deaths of people. However, the relationship between livestock products and diseases is not always true because the amounts of fat and cholesterol and types of fatty acids in meat and meat by-products depend on the part of the meat and types of animals. Although meat intakes do not always cause mai or adult diseases, still the developmental necessity does exist for animal foods equipped with biologically active properties, which in turn can improve nutritional status and health more than ever Meat with high protein lean part and low fat can be produced by applying synthetic somatotropin and beta-adrenergic agonists like clenbuterol, cimaterol etc. during breeding. This application brings benefits like higher growth rate, lower fat contents and improve feed efficiency ratios. Meats fortified with long chain PUFA($\omega$-3 fatty acids) can also be produced by modulating feed composition.Egg Products have faced the reduced sales annually because of its high cholesterol contents. Recently brand eggs fortified with special nutrients or chemical components having functional proper ties in the human body system are very popular Research Interests have been focused on eggs with low cholesterol and high omega-3 fatty acids. Low cholesterol eggs and high omega-3 eggs can be produced in several different ways, but popular way to increase is feeding the feeds with different oil sources containing high omega-3 and 6 fatty acids such as fish oil, perilla oil, linseed oil and lecithin etc. But proper compositon of feed formula should be found and economically beneficial. Brand eggs fortified with vitamin, mineral, unknown growth factors are also manufactured. Low cholesterol and high $\omega$-3 PUFA milk are marketed recently Cholesterol removal technology is not completely established and has several limitations to be overcome. Milk fortified with $\omega$-3 fatty acids is made by incorporating high &13 fatty acid foods in feed despite of extraordinary way of fatty acid metabolism In cow. All these biologically active products will be very beneficial and useful for human consumption when limitations of manufacturing technology such as safety and lowered sensory qualities are resolved. Furthermore, thorough and precise tests and quality control for these products should be performed to ensure the effectiveness and usefulness in terms of improving health and nutritional status in general. However one caution should be pointed out to lay people informing that these items are nothing but a food and not panacea. Therefore, it is important to remember that the only way of maintaining good health is absolutely through consuming balanced diet.

본 고는 한국상품문화디자인학회 제40호 논문집에서 발췌한 것으로 학회의 동의 아래 게재함을 밝힌다. 최근 무역환경 변화에 따라 경쟁력이 열악한 국내 농산물 시장은 혼란이 가중되고 있으며, 시장이 세분화되고 고객의 욕구가 다양해지며 농산물 제품도 품질, 기능, 가격 등의 경쟁력만으로는 더 이상 시장에서 경쟁력을 확보할 수 없다. 급속도로 변화하는 사회 환경과 시장 변화에서 소비자의 구매 욕구를 충족시키고 기존 농산물과 차별화된 독창성을 부각시키기 위해 농산물 마케팅이 중요 과제로 연구되고 있다. 또한 농업 마케팅 분야에서 포장디자인이 소비자의 구매 욕구를 유발시키는 중요한 요소로 부각되며 제품 경쟁력을 확보하는데 필수적이라는 인식이 광범위하게 확산되고 있다. 본 연구에서는 농업 생산물 중계란 포장디자인 개발을 중심으로 소비자가 기억할 수 있는 브랜드네이밍, 구매 욕구를 유발시킬 수 있는 포장디자인 콘셉트를 제시하고자 한다. 특히 온라인 판매용으로 개발되는 계란 포장디자인은 브랜드네이밍이 매우 중요하며 유통과정에서 제품의 운반, 보호를 위한 기능까지도 고려하여 하기 때문에 조형성, 기능성, 심미성, 합목적성으로 제작, 설계된 디자인 방안을 제언하고자 한다.

본 실험은 경기 북부 일부 지역의 계란에서 미생물 오염도를 측정하여 계란의 위생 상태를 파악하고자 하였다. 조사 자료로서는 대형 마트에 유통 중인 계란 중에서 서로 브랜드가 다른 계란을 대상으로 하였다. 계란의 난각에 존재하는 일반 세균수를 측정하였다. 그 결과 $3.4{\times}10^4cfu/m{\ell}$로 상당히 높은 일반 세균수가 검출되었다. 다음으로는 식중독 지수의 중요한 지표가 되는 대장균 및 계란으로 인한 식중독에서 주요 원인 균으로 작용하는 살모넬라균의 오염 여부를 파악한 결과, 한 브랜드의 계란에서 대장균이 검출되었고, 살모넬라균은 검출되지 않았다. 또한 각 브랜드에 계란에서 검출된 세균을 분리 동정 한 결과, Klebsiella pneumoniae, Pseudomonas mendocina, Alcaligenes xylosoxidans, Alcaligenes faecalis, Enterobacter cloacae 등이 분리되었다. 이 세균들 중 일부는 사람에게 병원성을 나타내거나, 면역력이 약한 노약자나 어린이에게 기회감염 또는 병원 내 감염을 일으키기도 하는 것으로 알려졌다. 계란의 난각에서 분리된 대장균의 병원성 여부를 판정하기 위하여, 대장균의 DNA를 분리하여 PCR을 수행한 결과, 병원성 대장균들에서 특이적으로 나타나는 유전자형을 가지고 있지 않는 것으로 밝혀졌다. 위의 결과들을 종합하여 보면, 시중에 유통중인 계란의 난각에서 비록 살모넬라균과 병원성 대장균은 검출되지 않았지만, 사람에게 감염을 일으킬 수 있는 여러 병원성 세균들이 검출됨으로써 계란의 유통 및 판매에 더욱 철저한 위생관리가 필요할 것으로 사료된다.
