| A "hybrid" spatial price equilibrium model is developed to evaluate changes in production, consumption, and trade of feed and malting barley under alternative domestic and agricultural trade policy regimes. The analysis includes the economic welfare impacts of changes in various farm subsidy programs on the United States, Canada, Australia, and European Union (EU-15) which are the four major barley exporting countries in the world. The actions of competitive U.S. grain traders under the Export Enhancement Program cause feed barley exports to be segmented into two distinct markets. A spatial equilibrium is established in which the Canadian Wheat Board and Australian marketing boards behave as oligopolists in export markets under arbitrage conditions induced... |

| Oats is one of the most important crops in Wisconsin. Its acreage (nearly 2 million acres) is second only to corn of all grain crops. In most of this acreage it is seeded as a companion crop to new alfalfa seedings and the usual practice is to harvest oats for grain. The Wisconsin Department of Agriculture Statistical Service has recently reported a decrease in the acreage of oats along with an increase in the acreage of alfalfa. Since alfalfa is the most important crop in teh strate in terms of acreage, and since some of the disadvantages of oast as companion crop outweigh the advanrages, it appears that this is probably one of the teasons for this acreage decrease. Lodging undoubtedly is the major problem with this grain crop. Up to the present rime,... |

| The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions: absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics.... |

| The NAHMS Cattle on Feed Evaluation (COFE) was designed to provide both participants and the industry with information on the nation's feedlot animal population for education and research. The USDA's National Agricultural Statistics Service (NASS) collaborated with NAHMS to select a statistically valid producer sample (3,214 producers) to provide inferences to the nation's feedlot animal population. Included in the study were 13 states that accounted for 85.8 percent of the U.S. cattle-on-feed inventory as of January 1, 1994. NASS telephone interviewers contacted a total of 3,214 producers by telephone or personal interview from August 1 through September 16, 1994 for Part I. Contact for this paper: David Dargatz |

| O objetivo deste trabalho foi estudar os efeitos de diferentes niveis de volumoso nas dietas sobre as exigencias liquidas e dieteticas de calcio (Ca), fosforo (P), magnesio (Mg), sodio (Na) e potassio (k) de bezerros mesticos (Holandes x Zebu) em crescimento. Quarenta e oito bezeerros mesticos foram alimentados a vontade e distribuidos em cinco grupos de oito animais, de acordo com cada sistema de alimentacao (Tratamentos). Os seguintes niveis de volumoso nas dietas, na base da materia seca, foram usados: T1 = 10%; T2 = 25%; T3 = 40%; T4 = 55% e T5 = 90%. As deposicoes de calcio e magnesio para ganho de peso de corpo vazio (PCVZ) aumentaram, ao passo que as exigencias dieteticas de calcio e fosforo, praticamente, nao mudaram, a medida que o peso do animal... |

| Este trabalho foi conduzido para avaliar o efeito dos diferentes niveis de voloumoso nas dietas sobre o consumo medio diario de materia seca total (CDMST), o ganho medio de peso, a conversao alimentar e o rendimento da carcaca. Trinta e seis bezerros da raca Holandesa puros por cruzamento, com idade media de 60 dias e peso vivo(PV) inicial de 78kg, foram distribuidos em delineamento inteiramente casualizado. Os animais foram alimentados a vontade com dietas contendo niveis de 10,25,40 e 55% de volumoso, na base da MS, usando-se feno de capim coast-cross (Cynodon dactylon), fuba de milho e farelo de soja, os quais constituiram dietas com aproximadamente 16% de PB. Os animais foram pesados a cada periodo de 28 dias, com pesagens mais frequentes para os... |

| The NAHMS Dairy '96 Study was designed to provide both participants and the industry with information on the nation's dairy animal population for education and research. This report contains demographic changes of the U.S. and world dairy industry from a historical perspective from data provided by the National Agricultural Statistics Service (NASS), Census of Agriculture, and Foreign Agriculture Service. Results of two NAHMS national studies overview changes in the U.S. dairy industry in the 5-year period of 1991 to 1996. The 1991 National Dairy Heifer Evaluation Project included herds of 30 or more milk cows and heifer-rearing operations in 28 states representing 83 percent of U.S. milk cows. NAHMS Dairy '96 described dairy production for operations... |
