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.

Identification of salmonellosis-infected commercial poultry flocks has become a pivotal component of efforts to reduce incidence of egg-associated transmission of S. enteritidis and S. typhimurium to humans. As a basic study for sanitary control of S. enteritidis and S. typhimurium, main food-borne pathogenic bacteria in eggs produced by domestic hens, commercial egg samples were tested for specific antibodies to whole cells of S. enteritidis and S. typhimurium and outer membrane protein(OMP) of S. typhimurium by ELISA to detect infection of S. enteritidis and S. typhimurium in various groups of hens. When the antibody titers of yolks from three commercial brand eggs were tested after diluting in the ratio from 1:100 to 1:1,600 with double dilution method, ELISA values of the specific antibodies could be shown as differences in dilution patterns by comparing with negative control egg. When the antibody titers of the yolks from two commercial brand eggs were tested after diluting in the ratio of 1:200 and 1:1,000, ELISA values of specific antibodies were different among same brand eggs. When the antibody titers of yolks from five eggs sampled randomly from twenty one commercial brand eggs were tested after diluting in the ratio of 1:1,000, ELISA value of the specific antibodies were shown generally high. ELISA values of 28.5, 30, and 28.5% of yolks from 21 brand eggs were shown low and similar to negative control egg in antibody titers to whole cells of S. enteritidis and S. typhimurium and OMP of S. typhimurium, respectively. The results demonstrated that ELISA test of egg yolk antibody could provide a highly sensitive indicator to detect contamination of S. typhimurium and S. enteritidis in poultry, and could be used effectively to reduce incidence of S. typhimurium and S. enteritidis infection in poultry.

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.

Microorganisms or their toxins can be transferred to eggs and cause food poisoning in humans. Therefore, this study was conducted to detect microbial contamination of eggs and to identify microorganisms in any contaminated eggs. Four different brands of eggs were collected from hypermarkets in the northern Gyeonggi area. The total bacterial counts on the shells of the eggs varied greatly between brands. In addition, various bacterial species including Klebsiella pneumoniae, Pseudomonas mendocina, Alcaligenes xylosoxidans, Alcaligenes faecalis, and Enterobacter cloacae were identified on eggshells. Furthermore, mean of total bacterial counts of four brands was $3.4{\times}10^4 cfu/m{\ell}$ and E. coli was detected on the eggshell of one brand egg. However, Salmonella was not identified on all brands of collected eggs. We also demonstrated that the E. coli isolated from the eggshell was not pathogenic based on the absence of pathogen-specific gene expression patterns. Taken together, the result of this study indicate that strict quality control and improved distribution controls are required to decrease microbial contamination and improve human health.
