To investigate the changes in blood pictures of Korean native goat during gestation the erythrocytes, leukocytes, hemoglobin concentrations, hematocrit values and differential leukocyte counts ware measured and blood was collected from jugular vein, uterine artery and vein in maternal and umbilical artery and vein in fetus. The results were summarized as follows; 1. Erythrocytes and hemoglobin concentration were continuously increased during gestation and hematocrit values until 120 days of gestation were increased just before parturition in maternal. 2. In the fetus, erythrocytes, hemoglobin concentration and hematocrit value were continuously increased during gestation. 3. Total leukocytes was increased after 30 days of gestation according to progress of gestation, the percentage of neutrophil was increased and lymphocyte was decreased. 4. Total leukocytes in the fetuses was not shown difference of the value which the range is 3,300-4,700/㎣. The percentage of neutrophil was suddenly increased, but lymphocyte was decreased during gestation.

Rice straw is the principal forage for Korean cattle. Limited supply of domestic forage forces Korea to depend on imported forage. Utilizing locally available domestic feed as an alternative would lead to self-sufficiency and stability in cattle farm management. Locally available feed can be utilized as forage. The challenge of collecting local feed has been overcome by machines that have been developed to harvest feed. Local feed can be completely consumed in the production regions, thus reducing transportation costs and increasing price competitiveness. Hitherto, studies have focused on feed technologies and price competitiveness, among other factors, while the substitution of forage has not been examined. This study conducts a quantitative analysis to estimate the extent to which local feed can replace existing forage. We find that local feed is cheaper, and abundantly available, and can thus replace high-quality forage.

Stabilizing the supply and demand and price of beef cattle has been an important goal of agricultural policy in Korea. But it seems to be difficult to maintain stable beef cattle price in spite of many efforts. This difficulty mainly due to the complex structure of supply and demand, no practical policy measures, unreasonable distribution structure, and cattle cycle, etc. Nowadays it is very important to protect cattle farmers` income by maintaining stable price in the open economy. Beef cattle price has been decreasing from the second half of 2011 because beef cattle heads have increased significantly since 2002. The purpose of this study is to suggest the policy measures to stabilize supply and demand of beef cattle in Korea. We analyzed the beef cattle policies initiated by government since 1980s including supply and demand, marketing, and promoting production, etc. Major results are summarized as follows. First, it needs to establish preliminary policies to stabilize the supply and demand of beef cattle like Japan. It is very difficult to recover the former price after outbreak of surplus because of slow response of supply. Second, calf price stabilization system should be improved more efficiently to protect beef fattening farms and cow-calf operations together. Third, KREI (Korea Rural Economy Institution) is expected to enhance the prediction function, such as supply and demand, cattle cycle, beef import, and meat consumption trends, etc. Fourth, it is desirable to implement voluntary quota system of beef cattle by the livestock cooperatives. Fifth, public ranch can contribute to stabilize supply and demand of calf through purchasing system.

Agricultural business diversification and integration (ABDI) policy, usually called as a name of the 6th industralization policy in Korea and Japan, has been promoting actively by Korean government. This policy aims to overcome the difficult situation such as market liberalization and rapid aging at the Korean rural area. It is very important to utilize the various seeds in rural area and to catch the changing trends of consumers` needs to succeed the ABDI. Small rural businesses operations should collaborate together by network system. The function and effect of economies of linkage, as well as the economies of scope and scale is very important from the viewpoint of network and collaboration. Korean government has been legislating the Rural Industry Development Act (RIDA) to support the ABDI policy since 2013. In present the dominant types of business composition in the ABDI are processing with direct sale and experiencing tourism type and processing with experiencing tourism type. Rice, vegetables, fruits, herb plants, and livestock products are major raw materials of ABDI. Two big characteristics of Korean ABDI in comparison with Japan are large share of experiencing tourism and small weight of direct sale shops. There are various types of ABDI in Korea now, such as, production-oriented type, processing-oriented type, marketing-oriented type, experiencing tourism-oriented type, farm restaurant-oriented type, and healing-oriented type, etc. Gangwon Province has good infrastructure and many excellent leaders in the rural area because of the Rural Community Renewal Campaign (RCRC) since 1998. Several points were suggested to accelerate the ABDI in Gangwon Province as follows. Firstly, various seeds in Gangwon rural area should be investigated and analyzed in detail. Secondly, it is desirable to link the community businesses of model villages of RCRC to ABDI. Thirdly, it needs to establish the supporting institutions to help and train the ABDI operations efficiently, such as ABDI Support Center, ABDI Business School, and Food Development and Technology Support Center (FDTSC), etc. The main function of the ABDI Business School is to educate and train farmers about the food processing and rural business. Retired experts can help farmers voluntarily.

With the opening up of the market and the over-supply of domestic beef, there has been an occasional decline in the price of beef. This brings an adverse impact on Korean cattle farmers` income and challenges the sustainable development of beef industry. Exporting beef is an effective way to solve this problem. The FTA between South Korea and China will open up the two countries` beef markets and create more opportunities for Korean beef to access the Chinese market. China is a large player in cattle raising with vast resources, but its feeding model is mainly small-scale and based on traditional methods. After 2000, the number of cattle raised by the Chinese has consistently decreased. In terms of variety, production and technology, China still lags far behind developed countries. Furthermore, the quality of Chinese beef is of a lesser quality. With the strengthening Chinese economy, the standard of living has increased amongst its population. This results in more beef being consumed than pork. In particular, during the 21st century the demand for higher quality beef has seen rapid increases, and thus the price increases in line accordingly. This has resulted in foreign-reared beef entering the Chinese market. With this in mind, Korean beef can maximize the opportunity to enter the high-end market to satisfy demand. This paper will analyse the current development and future trends of China`s beef industry and, considering the market and consumption, promote a strategy for the Korean beef to enter the mainland China and Hong Kong beef market.

The characteristics of beef cattle promotion policies in Japan can be summarized as follows. Firstly, various policies have been devised comprehensively to promote beef cattle industry. To begin with stabilizing beef price and supply & demand, Price Stabilization Policy for Meat plays an important role. Besides, Deficiency Payment Policy for Beef Feeder Calves is being implemented to stabilize calf prices. In addition, in order to stabilize feed price and livestock farming, Price Stabilization Program for Formula Feed is also being put in operation. Secondly, beef cattle farming is apt to be influenced in itself by calf price fluctuations and sharp price rise of imported feed grain because of long production period. Then Japanese government has been enforcing the Support Program for Cow-Calf Operations and Special Support Program for Feeder Cattle Operations in order to decrease the management risk of beef cattle farms. Thirdly, beef cattle farmers have been actively participating in raising Price Stabilization Funds. For example, beef cattle farmers are paying a quarter of the Cow-Calf Operators` Reserve in Deficiency Payment Policy for Beef Feeder Calves. Beef cattle farmers are also contributing a quarter of Feeder Cattle Farmers` Reserve which is used in case of bad revenue in the Special Support Program for Feeder Cattle Operations. Moreover, livestock farmers are paying 600 Yen per tonne for Normal Compensation Fund in the Price Stabilization Program for Formula Feed. Lastly, most of Japanese policies for beef cattle promotion are complicated and with high cost structure in spite of their beneficial effects.
