The Korean dairy industry has been developed continuously for the past seventy years both in quality and quantity; now the total amount of dairy products accounts for 13 percent of that of livestock production - a remarkable turnover. Korea now stands at the 13th economic power around the world and it is inevitable that we must pursue an open-door policy at a global level; the dairy industry should also strengthen its potentialities in the long term in order to compete with advanced dairy countries. It is predicted that the impact of DDA agreement and FTA negotiations on the domestic dairy industry will be great; so it is urgently needed that we should reconsider the current status of the dairy industry and comprehensive mesures for dairy industry development to improve its international competitiveness. Such measures comprise the three aspects: first, reforming the policy of dairy industry-related systems, second, improving the productivity and third, expanding the consumption of dairy products. In terms of the system reforming, the most important things are, above all, the planned production relevant to market needs, the milk supply and demand management, and the raw milk transaction method. Secondly, the appropriate scale of management is important for the enhancement of productivity together with the modernization of dairy facilities. Thirdly, step-up effort is needed to expand the milk consumption; especially, more milk should be provided to the students by improving the standing milk ration system in middle and senior high schools. The government should make more effort to support and develop new dairy products tuned to consumers' taste, accelerating the publicity of diverse and steady milk consumption together with related organizations.

Animals produce important co-products such as meat, milk, and egg. Higher consumption and urbanization asked for more animal products and the demand was so strong that lager livestocks are now being raised densely in small farm. Large production of excreta and maldor is an inevitable consequence of condensed breeding. If this malodor couldn't be controlled, it could be chief obstacle to development of both livestock industry and environment of future. Major odor produced from livestock environments could be subdivided into four major sections: volatile fatty acids, ammonia and volatile amine, indole and phenols, and sulfur compounds. More than half of nitrogen excreted urea, so low protein feeding, synthetic amino acid feeding and supplementing with digestive enzyme, microbial agents and/or probiotics are methods for reducing nitrogen excretion. A lot of studies about feeding and probiotics, co-feed have been researched to improve environment and/or productivity in livestock industry.

Rendering, is attracting attention as a technology that can stably and quickly process livestock carcasses. However, large amounts of livestock carcass solid residues are discharged in this process and limited methods are available for recycling them. In this study, rendered animal carcass solid residues were pyrolyzed to produce carbonized materials (350℃; RACR-C) and their chemical properties were investigated. Further, RACR-C were applied to cabbage cultivation for investigating their crop growth characteristics and soil improvement effects. RACR-C contained large amounts of fertilizer components such as nitrogen and phosphorus, and showed no toxic effects on the seedling growth of crops. The content of water-soluble nutrients released from RACR-C under the reaction time increased rapidly within 30 min, but was insignificant compared to the total content. Thus, most fertilizer components in RACR-C were not readily soluble in water. The optimal application amount for applying RACR-C to cabbage cultivation based on the changes in cabbage growth, inorganic content, and soil chemistry was 200 kg/10a. Overall, pyrolysis of solid residues after rendering livestock carcass to produce carbonized material as a soil improver is an effective method to recycle the waste discharged from the rendering process.

Healthy living is an essential element of human happiness. Quality eating provides the basis for life, and the health of livestock, which provides meat and dairy products, has a direct impact on human health. In the case of calves, diarrhea is the cause of all diseases.In this paper, we use a sensor to measure calf 's biometric data to diagnose calf diarrhea. The collected biometric data is subjected to a preprocessing process for use as meaningful information. We measure calf birth history and calf biometrics. The ontology is constructed by inputting environmental information of housing and biochemistry, immunity, and measurement information of human body for disease management. We will build a knowledge base for predicting calf diarrhea by predicting calf diarrhea through logical reasoning. Predict diarrhea with the knowledge base on the name of the disease, cause, timing and symptoms of livestock diseases. These knowledge bases can be expressed as domain ontologies for parent ontology and prediction, and as a result, treatment and prevention methods can be suggested.

With the demand for free-range products increasing and the pressure on the intensive poultry industry to improve poultry welfare especially in western countries, the number of free-range poultry farms has increased significantly. The USA, Australia and European countries have developed Codes of Practice for free-range poultry farming which detail the minimum standards of husbandry and welfare for birds. However, the performance and liveability of free-range birds needs to be improved and more knowledge is required on bird husbandry, feed supply, disease control and heat wave management. This review examines the husbandry, welfare, nutrition and disease issues associated with free-range poultry systems and discusses the potential of incorporating free-range poultry into a crop-pasture rotation system.

Genetic modification enables modification of target genes or genome structure in livestock and experimental animals. These technologies have not only advanced bioscience but also improved agricultural productivity. To introduce a foreign transgene, the piggyBac transposon element/transposase system could be used for production of transgenic animals and specific target protein-expressing animal cells. In addition, the clustered regularly interspaced short palindromic repeat-CRISPR associated protein 9 (CRISPR-Cas9) system have been utilized to generate chickens with knockout of G0/G1 switch gene 2 (G0S2) and myostatin, which are related to lipid deposition and muscle growth, respectively. These experimental chickens could be the invaluable genetic resources to investigate the regulatory pathways and mechanisms of improvement of economic traits such as fat quantity and growth. The gene-edited animals could also be applicable to the livestock industry.

Mongolian herders rely significantly on grazing their animals, such as goats, sheep, cattle, horses, yaks, and camels, in broad rangelands throughout the year. The availability of appropriate forage, the amount of hay and forage to be kept, and whether the animals will acquire physical strength from the pasture to make it through the impending cold season are all determined by the meteorological conditions of the year. Herders' principal source of income is animals, therefore preventing mortality is a top priority. In Mongolia, meadows are a major element determining cattle live weight. However, in the summer of 2022, Mongolia faced a drought, which resulted in inadequate pastures and starved cattle. Livestock might lose weight in these situations due to a lack of supplemental feeding.

The competition between countries became internationalized in the market. However, a situation in which globalization is concerned is important to domestic corporates. Corporate strategy to survive in the domestic market are also juggling the limit of survival. Technology transfer and commercialization at this point has important implications now. The same applies to the national level. Public-to-private technology transfer has been more important, in order to overcome the international competitions. Although various studies have been made to promote technology transfer, in the livestock sector rarely attempted. Taking into account that few previous research and theory development has been achieved, the paper explored the technology transfer phenomenon in the sector employing the grounded theory approach by Strauss & Corbin(1998). Corporates that licensed in technologies through the Foundation of Agri. Tech. Commercialization & Transfer, were targeted as informants or interviewees. Finally, eight informants were selected sequentially utilizing theoretical sampling technique to the saturation point. As the result of open coding and axial coding of the interview data using NVivo10 by QSR International, 77 concepts, 20 sub-categories, and 7 categories were derived while paradigm model was established. Through selective coding, 'the factors affecting technology transfer in livestock sector' was identified as core category. The story line about the core category was developed based on four main categories. Finally, it is expected that the concepts, categories, and the relationship between them can be an important basis for further research.

Ticks cause economic losses to the deer industry by decreasing the growth and production of the farmed animals. The mediation of ticks affects humans and animals by causing contagious disease both directly and indirectly. Blood from farmed deer from the areas near Jangsu branch was collected for screening of infectious protozoa and rickettsial disease. Seventy deer blood samples were collected from 30 different deer farms located in Jinan, Jangsu and Muju. This blood samples were used for blood slide smear examination and hematological analysis. DNA from these samples was extracted and was used for PCR analysis for detection of gene fragments of Theileria spp, Babesia spp, Anaplasma spp and Ehrlichia spp. In the blood slide smear examination and PCR analysis all samples did not show presence of protozoal and rickettsial diseases. Eight blood samples showed anemia, 1 sample showed iron deficiency and 7 samples showed regenerative anemia. Results for PCR analysis showed 2 samples were positive for T orientalis. All DNA samples were negative for Babesia spp, Anaplasma spp, and Ehrlichia spp.
