This study estimates Korea's livestock energy consumption and GHG emissions from Korean livestock sector. The results show that livestock energy consumption in 2013 is 474 thousand TOE, 19.0% of total energy consumption in agriculture sector. It is estimated that GHG emission of fuel combustion from livestock sector is 956 thousand tons of $CO_2$ equivalent while a total of 4,589 thousand tons of $CO_2$ equivalent is emitted from agriculture sector. The livestock GHG emission as a proportion of the total agriculture GHG emissions (20.8%) is higher than the livestock energy consumption as a proportion of agriculture energy consumption (19.0%). This is because coal and petroleum consumption in livestock sector as a proportion of the total livestock energy consumption is higher than that in agriculture sector.

This study was performed to estimate the daily water consumption for watering livestock and home use, and to organize the water systems in the rural districts of Korea. For these purposes, 560 farms and other 40 urban families were randomly chosen and investigated about their water systems and daily water consumption seasonally from July 20 to August 31, 1973, and other 82 livestock raisers' useful data for watering livestock helped the study to assess the consumption of livestock water and compare it to that of general farms which bred some domestic animals as their sidelines. The results of data showed that the daily consumption of water was varied with the difference of districts and seasons in which the investigations were conducted. The results were summarized as follows. 1. The mean consumption of water for home use was varied with the range of 30.2-48.7 lit./day in summer and 22.4-45.2 lit./day per a person, respectively, in the rural districts, which showed that the water consumption in summer was more than in autumn. 2. The mean consumption of livestock water in the general farms approached to about 15.8-37.1 lit./day per cattle, 3.87-16.45 lit./day per a pig, and 0.19-1.03 lit./day per chicken, but it was slightly reduced in autumn; 10.89-37.09 lit./day per cattle, 3.87-12.63 lit./day per a pig, and 0.06-0.94 lit./day per chicken. The ratio of livestock water consumption to home use amounted to the range of 10-25%. 3. The mean consumption of livestock water used at the livestock raisers amounted to 134 lit./day per dairy cow, 67.4 lit./day per cattle, 43.29 lit./day per a horse, 13.24 lit./day per a pig, 0.438 lit./day per a layer, and 0.177 lit./day per a broiler, which showed that the daily water consumption for larger livestock was about two times as much as the farms, but it was approximately of the same for small ones. 4. The factors affecting the amount of water consumption for home use were statistically analyzed to find the kind of water sources and the class of water systems by the factorial arrangement method to the fundamental experimental unit, Suwon area of 100 of families, in which the former was very significant while the latter was significant. However, the standard of living and their interactions were not significant. 5. Almost 83.24% of the sampled farms used some kinds of wells as their water sources, of which 32.06% was of hard water, and of which 11.l% or 2.6% contained much of iron or organice materials, respectively, examining them by a simple technique of sensibility, 6. The resulting chart of the farm water systems was summarized as Fig. IV-6. Observating the safe distance from contamination sources, the ratio of 42.4% of sampled farms whose water sources were wells, confronted highly to the danger of contamination to their water sources. And other dangerous sources of contamination such as toilets, stalls, and compost heaps were situated nearly to the water sources, and most of them were able to make their spoiled water infiltrated into the ground. Thereafter, it was recommended to develop some protecting methods and to install some suitable faculties to clean water.

In Korea, the industry and marketing of livestock has grown because of increases in consumers' income and changes in food consumption trends. Livestock production and consumption increased tenfold from 1970 to 2018, and this rise will continue. However, the quality of marketing information for Korean livestock has remained low. The Korea Institute for Animal Products Quality Evaluation (KAPE) operates programs that provide marketing information on livestock, but the social benefits of these programs have not been objectively evaluated. The purpose of this study was to estimate the social benefit of the programs offering marketing information on Korean livestock. Survey and analysis using an economic model (double-bounded dichotomous choice contingent valuation model), revealed a few findings. First, the users of the marketing information programs offered by KAPE recognized the value of these programs and demonstrated their willingness to pay for this marketing information. Second, the social values of the programs offering marketing information on livestock were estimated as 1.1 billion won (marketing information on main livestock) or 5.3 billion won (price information on poultry), and these social values were 2 or 6 times greater than the cost to operate the programs for offering information. Finally, the program that provides marketing information on domestic livestock provides sufficient social benefits, so KAPE should expand these programs.

Estimation of food consumption details, such as portion size and frequency of consumption, is needed for exposure assessment step in microbiological risk assessment. This study investigated the amounts and frequencies of 50 kinds of consumed livestock products. A quantitative survey was performed by trained interviewers in face-to-face interviews with 1,500 adults aged over 19, who were randomly selected from seven major provinces in Korea. Respondents received a picture of one serving size for each of the 50 livestock products, including meats, processed meat products, milk and dairy products, and eggs and processed egg products. A t-test and general linear model were carried out using SPSS statistics. The most important factor affecting consumption of livestock products was residence area. The most frequently consumed food was milk (2.6 times/week), followed by pork (1.4 times/week), liquid yogurt (1.3 times/week), rolled omelet (1.2 times/week), semisolid yogurt (1.0 times/week), steamed egg (1.0 times/week), ice cream (0.9 times/week), chicken (0.8 times/week), low fat milk (0.7 times/week), and beef (0.6 times/week). In the case of consumption amount, people living in a city consumed meat (beef, pork, chicken, and duck) 1.5 times more than those living in a village, whereas milk and dairy products and eggs and processed egg products were consumed more frequently by people living in a town. When people eat meat, they consume twice the amount of one serving size. Students consumed livestock and processed livestock products more frequently with greater portions all at once. People living in Seoul, Incheon/Gyeonggi, and Busan/Ulsan/Gyeongnam consumed livestock products more frequently in large amounts. Data from this study can be used for risk assessment of livestock and processed livestock products as well as education for safe consumption of livestock products.

This study was conducted to determine recognition of Chikhanwoo, promote its market competitiveness, and vitalize its uses in Korea. This research was carried out on 465 people, including 264 of the general public and 191 livestock farmers. For awareness of Chikhanwoo, 53.6% of the general public and 86.9% of livestock farmers recognized Chikhanwoo (P<0.001) through TV, Internet, news, magazines, and others. For consumption behaviors of Chikhanwoo meat, 4.3% of the general public and 1.9% of livestock farmers have purchased Chikhanwoo meat in the past. Most of them hinted at their intention to repurchase and highly intimated their wish to purchase on whether Chikhanwoo tastes better, is more nutritious and is safer than Hanwoo. In addition, they thought country of origin and price were the most important factors for purchasing (P<0.001). For recognition of the Hanwoo grading system, they preferred $1^{{+}{+}}$ and $1^+$, significantly (P<0.001). For need for quality certification, most respondents thought that the government should introduce a quality certification system for Chikhanwoo. For importance factor of prevalence of Chikhanwoo meat, marketability value had the highest degree of importance, followed by taste, quality, tradition and cooking methods (P<0.001). Results of this study show that domestic consumption of Chikhanwoo can be boosted by supplying Chikhanwoo meat with a differentiated taste and a safety assurance to the general public. There is also need to enhance genetic resources and improve brand value of Chikhanwoo. Continuous research and efforts should be made for the development of the livestock market.

Influences on the environment from the consumption of livestock have increased drastically during the last 50 years in Korea. Reduction of bovine meat consumption is one of the alternatives as sustainable food supply. The consumption of bovine meat and the ecological footprint (the sum of the cropland, grazing land, and carbon footprint) from the consumption of bovine meat have increased over 13 and 12 times over the last 50 years. Especially, the consumption of imported bovine meat and the ecological footprint from the consumption of imported bovine meat have increased significantly about 346 and 369 times over the last 40 years. If the consumption of bovine meat decreased by half in Korea in 2023, the ecological footprint from the consumption of bovine meat would be reduced by 40~65% depending on the scenarios. The supportable population number for the consumptions of environmental resources (food (crops, livestock, and fish), energy, forest, and built-up land) and the crops were 0.57~1.56 million and 3.42~6.83 million, respectively, depending on the scenarios and the nationality of the supported people.

There are approximately 250,000 organic livestock farming in the world. The total retail value of organic food sales in the world is $ 27 billion. The organic livestock products such as milk, lamb and beef are marketed mostly in Europe and the USA. The market share of organic food is about 2% in total food marketing value of worldwide and of the organic food marketing value, organic livestock products portioned 17% in the USA. The organic livestock products are primarily marketed at Supermarket(Europe), Health and Natural Food store(USA). Concerning international trade, it is very little. But it is increasing among the developed counties of Europe. In the future, the production of organic livestock products will be rapidly increased in South America, Middle East and Oceania, but the growth rate will be limited due to its expensive price, lack of marketing-infra and different regulation system. Most of developed countries drive organic farming policy strongly as the strategic means of rural development, diversifying agriculture system and environmental improvement.

The pale, soft, exudative (PSE) syndrome lowers storage quality and consumers acceptability in the particular meat. With the increase in the consumption of parted chickens in Korean meat consumption trade, a parallel increase in the concern over the PSE status of chickens have been noticed. The present study focused on the PSE status of broiler's breast to investigate the effects of different degrees of PSE on its quality and storage characteristics. A total of 46 broiler chickens of 35 days old averaging 1,251-1,350 g were selected for the study. Breast separated and skin was removed. The breast meat was stored at $4^{\circ}C$ for 3 days and were analysed for pH, lightness, yellowness, redness, shear force, water-holding capacity (WHC), cooking loss, Thiobarbituric acid reactive substances (TBARS) and Volatile basic nitrogen (VBN) on day 1 and 3 during the storage. Increase in the degree of broilers breast PSE during storage caused fall in pH and shear force and increase in lightness, cooking loss, TBARS, VBN. Broilers breast PSE status confirms the actual pale soft and exudative nature of meat.

The demand for livestock and poultry products including beef, pork, chicken, egg and milk whose income elasticities are relatively higher than other staple foods, has been increased significantly during the past two decades in response to the remarkable increase in per capita GNP. This trend will be continued during the fifth and the sixth five year economic development plan period beginning with 1982. The annual GNP growth rate will be 7.5% on the average during the next 10 years. It is greatly needed to estimate the demand for beef, pork, chicken egg and milk and to study the feasibilities of domestic production of livestock products for the formulation of adequate policies in order to equate the consumption and the production during the 1980s. So this study reviewed the possible changes in the food consumption patterns during the 1980s, estimated the demand for beef, pork, chicken, egg and milk by using empirical demand functions and finally made suggestions for the formulation of long term price stabilization policies for each livestock, poultry and dairy products through the equilibrium of the quantity of demand for and supply of the products. There are many factors affecting the demand for meats, but this study considered own price, prices of supplements and substitutes and per capita income as the independent variables in the demand equations. It was found that it's own price and income were most significantly affecting factors among others and the degree of substitution effects were remarkably different among the products. According to the meat demand derived in this study, per capita consumption of beef, pork and chicken in the base year 1982 was 11.2kg for total meat, 2.5kg beef, 6.0kg pork and 2.5kg chicken, 106 pieces egg, 15.1kg milk respectively, while those in 1991 were 19.3kg for total meat, 4.8kg beef, 9.6kg pork, 4.9kg chicken, 133pieces egg and 44.1kg milk. It is also predicted through this study that, when the level of production costs be maintained, the domestic production of pork and chicken will meet the demand for them during the fifth and sixth five year economic plan period. However, there will be chronic shortage of beef supply during the coming years. The annual import requirement will be 30,000tons to 40,000tons during the period. In order to stabilize the domestic livestock and poultry and dairy products market, the government should introduce measures to curb the increase in beef consumption by encouraging the consumption of pork and chicken. For this, the livestock production policy measures should be concentrated on : 1) the improvement of infrastructures of beef production by introducing advanced feeding and management technology, subsidies for the establishment of facilities and price support programs for farmers : 2) the development of dairy beef : 3) the reinforcement of the forecast systems for pork and chicken production and consumption.

Recently, the importance of livestock statistics is increasing because of the food consumption pattern in Korea is changing. We compare the old sample design based on the 1995 National Agriculture Census with the new sample design based on the 2000 National Agriculture Census. We present some considerations to improve the efficiency of the sample design in livestock sector survey.
