  • The study was attempted to scrutinize the normal osmotic fragility of erythrocytes in domestic poultry such as chicken, quail and duck making a comparison with that in domestic mammalia such as dog and pig. Osmotic fragility of erythrocytes was determined on blood samples from 10 healthy adult animal in each species. Optical initial hemolysis of erytyrocytes occurred at $0.395{\pm}0.03%$ Nacl for chicken, $0.410{\pm}0.03%$ for duck, $0.440{\pm}0.02%$ for quail, $0.470{\pm}0.05%$ for dog and $0.560{\pm}0.03%$ for pig. Optical complete hemolysis of erytyrocytes occurred at $0.270{\pm}0.02%$ Nacl for chicken, $305{\pm0}.03%$ for duck, $0.360{\pm}0.02%$ for quail, $0.370{\pm}0.03%$ for dog and $0.455{\pm}0.03%$ for p. In other words, erythrocytes of poultry have stronger resistance to osmotic Iysis than that of mammalia, showing the strongest resistance In chicken among the tested poultry.

  • Poultry is one of the three major meats in Korea and is a representative source of protein. The annual per capita consumption of chicken has been showing steady growth trends, with an increase of approximately 89% in 2018 compared to that of 2005. In this study, we investigated the domestic chicken production and consumption, and conducted an overall study on the domestic chicken industry. By using consumer panel data, we analyzed the characteristics of consumers buying chicken. Specifically, poultry was categorized into two types: traditional raw chicken and processed chicken, which emphasizes convenience. The purchase of raw chickens has generally been on the decline. From these, however, the proportion of native Korean chicken and chicken cuts is on the rise. Processed chicken, on the other hand, continues to grow, especially online. After examining the consumption characteristics of consumers who buy chicken, it was found that the purchase share increased with increasing age of native Korean chickens, whereas the purchase share increased with decreasing age of processed chicken. Based on these results, we confirmed that it is necessary to establish differentiated marketing and promotion strategies for each consumer target for the growth of chicken market.

  • The cafeteria of university is one of the largest consumption point for the chicken meat of university students. However, few papers conducted research to analyze the consumption behavior of university students. The object of this paper is to conduct survey analysis about the students' behavior for consumption of chicken meat at the cafeterias of university and to measure WTP (Willingness-to-pay) for food cooked with domestic chicken meat. The results present that most of students show higher preference of domestic chicken meat and that they can pay 4,426 Korean won for food cooked with domestic chicken meat.

  • The poultry industry in Korean has expanded considerably during the last 15 years. While the number of chicken farms of commercial scale has decreased steadily during the period average farm size increased rapidly. Though the gross national product per capita increased 4.5 folds during ten years period, consumption of chicken meat, like other meats, recorded only 2 folds increase during the period. When domestic market for chicken meat had been open for two years on the basis of minimum market access quotas, importation remained at levels below the quota during the first one and half years. Nevertheless, during the last six months and thereafter, chicken meat importation recorded a steep increase, threatening the domestic industry. Poor productivities of the commercial chicken farms might be the main cause for the inferior competitiveness. For the sustainability of the industry some suggestions were made.
