World Soybean Demand: An Elasticity Analysis and Long-Term Projections

Soybeans are one of the most valuable crops in the world and are characterized by their multi-purpose uses: food, feed, fuel and other industrial usages such as paint, inks, and plastics. Out of 183.9 million tons of world supply/demand of soybeans in 2001-03 year, about 10% of them were directly consumed as food (5.9%) or feed (3.8%) but 84.2% of them were crushed into soyoil and soymeal. Soyoil is mainly processed to vegetable oil for human consumption and recently used as a biodiesel feedstock. Soymeal is used not only as feed for livestock (especially for pork and poultry due to its low fiber level) and aquaculture, but also as a good source of protein for the human diet in a variety of forms in different cultures. This paper analyzes the relationship of the demand for soybeans with economy at country and international levels. We use the county level domestic demand quantities with GDP data and apply an error correction mechanism (ECM) to estimate the long-term elasticities of demand for soybeans in the market/economy. Using the estimated long-term elasticities, the demands for soybeans are projected through 2030.soybean demand, elasticity, error correction mechanism (ECM), projection, Agribusiness, Crop Production/Industries, Demand and Price Analysis, Marketing, C22, C53, Q11,

Breast Cancer with Cartilaginous and/or Osseous Metaplasia Diagnosed by Lymph Nodal Metastasis:A Case Report

Breast cancer with cartilaginous and/or osseous metaplasia is a type of metaplastic carcinomas and is a rare disease. We report the case of a 49 year-old female who underwent right mastectomy for a large breast tumor. Histological examinations revealed a mixed tumor with both stromal and epithelial elements;the stroma showed poor differentiated spindle-shape and multiform cells with a massive osseous matrix, and atypical epithelial cells, which mainly existed on the surface of the cysts, showed nucleic atypia. The tumor was diagnosed as a malignant phyllodes tumor with osteosarcomatous differentiation;it was not identified as a metaplastic carcinoma because of the lack of proof of a cancerous component. Two years after a mastectomy, swelling of the axillary lymph nodes was found and a biopsy was performed. Histological findings for the lymph node indicated a metastasis of the invasive ductal carcinoma. The primary tumor was re-examined and was considered to be the origin of the lymph nodal metastasis. Lymph nodal metastasis of cancer proved that the primary tumor had cancerous potential, and the pathological diagnosis was altered to a breast cancer with cartilaginous and/or osseous metaplasia.</p

Abdominal wall and thigh abscess resulting from the penetration of ascending colon cancer.

An unusual case is described in which an abdominal wall and thigh abscess was an initial symptom of ascending colon cancer. A 76-year-old woman was referred to our hospital for investigation of fever and abdominal and thigh swelling. Computed tomography revealed a right abdominal wall, retroperitoneal, psoas and thigh abscess formation suspected to be caused by colon perforation. Due to the patient's poor general condition, local drainage of the abscess was performed on the following day of hospitalization. Histological examination of necrotic tissues removed form the retroperitoneal cavity demonstrated adenocarcinoma of the colon. The patient subsequently underwent right hemicolectomy with lymph nodal dissection after 19 days of the drainage procedure and was transferred to another hospital on the 49th day following the second surgery.</p

World Soybean Production: Area Harvested, Yield, and Long-Term Projections

Soybeans (Glycine max) serve as one of the most valuable crops in the world, not only as an oil seed crop and feed for livestock and aquaculture, but also as a good source of protein for the human diet and as a biofuel feedstock. The world soybean production increased by 4.6% annually from 1961 to 2007 and reached average annual production of 217.6 million tons in 2005-07. World production of soybeans is predicted to increase by 2.2% annually to 371.3 million tons by 2030 using an exponential smoothing model with a damped trend. Finally, three scenarios and their implications are presented for increasing supply as land availability declines. The scenarios highlight for agribusiness policy makers and managers the urgent need for significant investments in yield improving research

NSRL Soybean Specialty Grain Survey: Iowa

In 2007, the National Soybean Research Laboratory in collaboration with the Iowa Agricultural Statistical Service conducted a survey of the specialty soybean and corn activities in the State for the 2006 crop year. Out of 55,879 corn and soybean farmers in Iowa, 5,000 farmers were randomly selected and 2,369 farmers, responded, for a response rate of 47.4%. A key objective of the survey was to better understand, and then assess the state of differentiated or enhanced soybean and corn production in Iowa. The goal is to help farmers capture more value. This report is chiefly about soybean specialty crops, but a few points of comparison with corn specialty crops will be of interest. There is a companion report chiefly about corn that can be downloaded at the ageconsearch website

China's Meat and Egg Production and Soybean Meal Demand for Feed: An Elasticity Analysis and Long-Term Projections

China is a large meat and egg producer and correspondingly a large soybean meal consumer. Dual forces affect the derived demand for soybeans; rising livestock production to meet consum-er demand for protein and the shift to commercial feed by the livestock industry. We employ a unique elasticity approach to estimate these dual forces on soybean meal demand over the next 20 years. We then discuss the implications of these forecasts with respect to the modernization of China’s feed industry, land use changes in South America, and the need for yield research to reduce pressure on increasingly scarce land resources
