□ Feeding effect of ruminant protective coating amono-acid and Vit C additives on yearling steers forf Hanwoo beef for export
Studies of Hanwoo beef export possibility to Japan, China and Honkong since 2010, suggested market informations, buyer`s systemic management, domestic slaughtering facility improvement, quarantine and hygiene conditions in the countries. As Hanryu culture is spreading with together Korean foods in the countries, Hanwoo beef export is interested in various divisions. So we surveyed the export conditions of Hanwoo beef and research of exporting customized meat production. The 25 yearling Hanwoo steers were examined to Control for high quality beef production program, Trt. 1. for amino acid + Vitamin C supplement and Trt. 2 for Vitamin C supplement to produce Hanwoo steer quality beef over 1^st grade from 16 to 28 months of age. Intial body weight was 255.9～256.8㎏ and not significant in shipment body weight as 688.1㎏(Trt. 1), 660.3(Con.) and 634.0㎏(Trt. 2), Feed consumption rate of Trt. 2 was 11.19～13.80㎏ higher than other treatment. Backfat thickness in quantity grade at 28months of age shipment was 7.5㎜ in Trt. 2 but, loin area was 85.9㎠ in Trt. 2 more wider than other treatments. Marbling score of quality grade was 4.25 of Trt. 2 and 4.13 Trt. 1 more higher than 2.78 of Control.
□ Feeding effect of ruminant protective coating amono-acid and Vit C additives on meat quality and sensory properties of Hanwoo beef for export
This study was conducted to investigate the physico-chemical meat quality and sensory properties of Hanwoo steers (n=15) which were divided into 3 groups raised with 2 different feeding conditions (control, no additives; T1, ruminant protective coating amino acids and Vit C addives; T2 ruminant protective coating Vit C additives) during 16~28 months old. The animals were slaughtered and evaluated the meat quality and sensory properties of loin and top round muscles. In the free amino acid contents of loin muscle, T1 had significantly higher serine, alanine, lysine, phenylalanine, tryptophane and T2 had significantly higher histidine than the other treatments(p<0.05). T1 had the significantly lower Warner-brazler shear force (WBSF) values than the control and T2, however, there were no significant differences in sarcomere length and water holding capacity(p>0.05). T1 of loin muscle had significantly lower saturated fatty acids and higher total contents of monounsaturated fatty acids than the other treatments(p<0.05). In conclusion, T1 had the significantly lower Warner-brazler shear force (WBSF) values and higher scores of flavor-likeness and overall likeness in sensory evaluation when they were compared with control and T2(p<0.05).
□ Establishment of distribution condition of Hanwoo beef for export
The study was conducted to investigate the export market and establish the distribution condition of Hanwoo beef initially targeted on Hong Kong and China. Loin, striploin, tenderloin and top round muscles produced from 1⁺⁺, 1⁺, 1 grade of Hanwoo steer beef were selected and meat quality changes were determined during 0, 7, 14 days of aging and 0, 3, 6, 9 months of freezing storage. Increasing the aging days, Warner-brazler shear force (WBSF) values of 4 cuts were decreased(p<0.05). Increasing the freezing periods increased, meat color (lightness, redness) and total contents of free amino acids
□ Establishment of Export Strategies of Hanwoo Beef to Major Partner Countries
The necessity of this study was raised based on the fact that the time has come for the policy that confronts the opening of the market in the near future and the stabilization of the Hanwoo Beef industry, as well as search for ways to enter the international market for the stable management of farms. The study for entry of Hanwoo Beef into the international market is in a relatively difficult position due to the quarantine-based import ban resulting from domestic animal diseases and relatively poor price competitiveness, thus calling for the study into the analysis of the local market and establishment of export strategies of Hanwoo Beef. Based on the objective analysis of Hanwoo Beef export policy and business that has been conducted so far, the purpose of the study is to establish export strategies of Hanwoo Beef into both the domestic and international markets, specifically Northeast Asian region(China, Hong Kong, Japan), through the analysis of export condition and feasibility of Hanwoo Beef.
□ Contents and Scope of the Study
Contents and scope of this study are in the following table, as to rank countries that are best suited for Korean beef export, to survey and analyze comprehensively and realistically marketing(4P) and features of individual cities of that coutnry, and to establish strategies for individual cities of major export countries.
Based on the result of the quantitative evaluation of the export environment of Hanwoo beef, it is concluded that high-quality parts of Hanwoo beef are commonly thought to have price competitiveness. Evaluated results that have been drawn suggest priority for cities and parts in which Hanwoo beef has export competitiveness. Also, based on the evaluated results, export strategies of individual cities(Hong Kong, Shanghai, Beijing, Tokyo, Osaka) are suggested.
□ Policy Proposal
First, it is proposed that division of works is to be launched for strategic and systematic execution of Hanwoo beef export, and Control Tower is to be established that has the responsibility to manage and control business promotion system and contents for integrated managenet.
Second, it is proposed that the budget is to be secured for Hanwoo beef export vitalization through revision of current laws regarding animal stock self-funds.
Third, it is proposed that three to four export-specific slaughterhouses are to be designated for each region and to possess highest-quality sanitation level, and systematic management to be carried out for minimization of problems that might arise from the slaughtering process.
Fourth, it is proposed that vitalization of Hanwoo beef export requires integrated certified brand mark, establishment of low-cost, customer-catered production and distribution systems, development of high-quality packing materials and designs, efficiency of export distribution, and other supports from various association and organizations.
