Análise funcional de genes candidatos para características de interesse econômico em bovinos da raça Canchim. Repositório Alice
SOUSA, I. N..
Sabe-se que a qualidade de um produto é o fator fundamental para que o mesmo possa ser inserido no mercado e o setor brasileiro de carne bovina tem se preocupado não só com o aumento da produção, mas também com a qualidade da carne produzida. No entanto, produtores enfretam dificuldades para obter a melhoria de características como a quantidade de gordura subcutânea e entremeada, ganho de peso, além da pelagem e da circunferência escrotal. Diversas metodologias foram desenvolvidas no intuito de obter resultados mais rápidos e mais acurados, como o uso de genes candidatos e análises individuais e adjacentes de SNPs que controlam a manifestação de características de interesse econômico, assim como estudos que visam elucidar a arquitetura biológica e...

Avaliação das mudanças na política de garantia de preços mínimos: período de 1997 a 2004 AgEcon
Del Bel Filho, Egmar; Bacha, Carlos Jose Caetano.
This paper evaluates the main changes that happened in the Brazilian policies of agricultural minimum price since 1997, paying attention to operational issues and discrepancies among regions and products that occurred when implementing those policies. In 1996, Brazilian Federal Government created two new programs, Prêmio de Escoamento de Produto (PEP) and Contratos de Opções de Venda de Produtos Agropecuários (COVPA), in addition to other two traditional programs (Aquisição do Governo Federal, AGF, and Empréstimos do Governo Federal, EGF). However, the new programs only were implemented one year after. Since then, these four Federal programs of minimum prices have had different performances. This paper evaluates those differences, highlighting unequal...

Characterization of the Brazilian vegetable brassicas production chain Horticultura Brasileira
Melo,Raphael AC; Vendrame,Larissa PC; Madeira,Nuno R; Blind,Ariel D; Vilela,Nirlene J.
ABSTRACT Brassica crops worldwide provide the greatest diversity of products used by man derived from a single genus. Collectively, leafy, flower and root vegetables can be eaten fresh, cooked and processed. The production of these vegetables in Brazil has been growing exponentially in the last decades, due to its economic importance, with major production volumes in several states and a quick monetary return for growers in areas considered of small acreage. With expansion, a number of aspects, including demands for quality and safety of these foods introduce themselves, strictly attached to the forms of production, logistics and their appearance. To meet the challenges and list the trends within the activities of different agents, a multiple case study...

CHINA'S FOOD AND AGRICULTURE: ISSUES FOR THE 21ST CENTURY AgEcon
China's impact on world agricultural markets in coming decades will depend on many factors. Growing income and transition to modern urban lifestyles will increase demand for all foods, but demand will shift toward meat and high-value products. WTO accession may increase openness of China's agricultural trade and allow more imports. An understanding of geographic variations of consumption, production, trade, and policy is critical to understanding the vast China market. Development of transportation infrastructure and market channels will make it easier for food products to reach consumers. China's approach to biotechnology and its reform of institutions for allocating land, labor, and water inputs have important implications for agricultural productive...

Effects of agri-environmental measures and changes in EU single farm payments on Dutch agriculture AgEcon
Helming, John F.M.; Schrijver, R.A.M..
Part of the Health check of the Common Agricultural Policy (CAP) of the European Union in 2008, will be a discussion of the linkage between direct payments to farmers and the contribution of agricultural production to social important values. The objective of this paper is to analyse the economic and environmental effects of extra region specific environmental measures and a redistribution of direct payments to the Dutch agricultural sector in 2020. In doing so a chain of models is used from the dairy farm level to the regional sector level in the Netherlands to the European sector level. From the dairy farm model it is found that the extra-environmental measures result in a decrease in the number of dairy cows per ha and a decrease in the gross margin per...

KRAM - A Sector Model of Danish Agriculture - Background and Framework Development AgEcon
Wiborg, Torben.
A model of the Danish agricultural sector named KRAM (KVL's Regionalized Agricultural Model) is developed in this paper. KRAM can be described as a spatial, dynamic, nonlinear, programming sector model. KRAM's purpose is to make policy analysis in the complex market conditions Danish agriculture is working under today. In order to do this in the best possible way the model optimizes the production functions on a very disaggregated level. This allows for analysis of changes in physical constraints to production, as well as price changes. The model is capable of calculating some environmental effects of agricultural production, and provides detailed spatial description of the agricultural economy and production. The time horizon is 10 years, and the model...

Monitoring regional economies in Australia: why and how AgEcon
Chapman, Paul; Coelho, Bruno.
Economic activity is inherently variable and monitoring it is a major challenge, especially in regional economies where resources are fewer and activity is more variable. Using a recent study of the Riverland region, the authors set out the information available, its limitations and means by which it may be extended. It is argued that monitoring must respond to specific needs and extend to information beyond the scope of the merely economic. It is not simply a matter of tracking commonly used economic variables but of understanding specific economic challenges and using that understanding to target economic and social information.

REFERENCE OF 1996 U.S. REGIONAL SHEEP HEALTH AND MANAGEMENT PRACTICES AgEcon
Wineland, Nora.
In 1995, the National Animal Health Monitoring System (NAHMS) collaborated with the Research and Education Division of the American Sheep Industry Association (ASI) in developing a needs assessment tool to identify the most important health and productivity factors for the sheep industry. In collaboration with the USDA's National Agricultural Statistics Service (NASS), a statistically designed producer sample was selected to provide estimates for the United States sheep population in the 48 contiguous states. The NAHMS/ASI questionnaires were mailed to 19,807 sheep operations in January 1996; data were received and summarized from 5,174 respondents. It was estimated that in the 48 contiguous states, there were approximately 8,433,400 sheep as of January...

Returns to Migration, Education, and Externalities in the European Union AgEcon
Rodriguez-Pose, Andres; Tselios, Vassilis.
Relatively little attention has been paid to the role that externalities play in determining the pecuniary returns to migration. This paper addresses this gap, using microeconomic data for more than 100,000 individuals living in the European Union (EU) for the period 1994-2001 in order to analyse whether the individual economic returns to education vary between migrants and nonmigrants and whether any observed differences in earnings between migrants and locals are affected by household and/or geographical (regional and interregional) externalities. The results point out that while education is a fundamental determinant of earnings., European labour markets – contrary to expectations – do not discriminate in the returns to education between migrants and...
