GRAZING MANAGEMENT, AMMONIA AND NITROUS OXIDE EMISSIONS: A GENERAL VIEW R.C. Suelo Nutr. Veg.
Núñez,Pedro; Demanet,Rolando; Matus,Francisco; Mora,Maria de la Luz.
The grazing management of grassland has a direct effect on nitrogen (N) recycling. This is an important reason why management has become an alternative to improve the grassland production and quality, in turn to make it more suitable for the environment. However, the livestock system intensification induces changes in the natural dynamics of the N cycle, accelerating gas emmisions (e.g. ammonia, NH3 and nitrous oxide, N(2)0) and leaching losses from soil under grazing. When the amount of N in the environment increases, there is an impact on smog episodes, global warming, stratospheric ozone depletion, acid rain and eutrophication of fresh water. There are different techniques to evaluate the gases emitted from the soil. This klonowledge is useful to design...

Human Resource Management in Beef Cattle Farms at Triangulo Mineiro Region AgEcon
Pereira, Mariana de Aragao; do Vale, Sonia Maria Leite Ribeiro; Mancio, Antonio Bento.
The marketing pressures for economically viable, socially fair and ecologically correct production systems have required the farmers to adopt new management practices, aiming to increase the production scale, improve the quality of the products, and reduce costs. The historical utilization of abundant, cheap and disqualified labor in the rural sector has been a barrier to the adoption of technology. This study is an attempt to describe the human resources management that have been used by beef cattle farmers, as well as to analyze the management performance in labor and technical areas during the 2000/2001 year. Three-hundred and twenty questionnaires were sent by mail to farmers in the Triangulo Mineiro region. All of them were registered in the Brazilian...

Impact of the South Korea-U.S. Free Trade Agreement on the U.S. Livestock Sector AgEcon
Fabiosa, Jacinto F.; Hayes, Dermot J.; Dong, Fengxia.
The recently signed Korea-U.S. Free Trade Agreement (KORUS FTA) grants the U.S. livestock industry with preferential access to South Korea's import market. This study evaluates the likely impacts of the KORUS FTA on the U.S. livestock sector. Using the Food and Agricultural Policy Research Institute's modeling system, we find that livestock prices increase by 0.5% to 3.8% under the agreement. And together with an expansion by 381 to 883 million pounds in meat exports, the value of U.S. exports increase by close to U.S.$2 billion, or a 15.2% increase. Because of differential baseline starting market shares and differential rates and staging specifications, the beef sector results are primarily driven by trade diversion impacts, while a combination of...

Impacts of Regulating Greenhouse Gas Emissions on Livestock Trade Flows AgEcon
Kim, Hyun Seok; Koo, Won W..
The policies that regulate greenhouse gas emissions would provide a significant burden to emission industries as well as final consumers, which can lead to a strong influence on international trade flows of commodities. This study examines the impact of regulating greenhouse gas emissions on livestock trade flows using a commodity specific gravity model approach. This study finds that regulating greenhouse gas emissions has a negative effect on livestock trade flows from countries restricting greenhouse gas emissions to unrestricting countries, from restricting to restricting countries, and from unrestricting to restricting countries.

Implications of the Biofuels Boom for the Global Livestock Industry: A Computable General Equilibrium Analysis AgEcon
Taheripour, Farzad; Hertel, Thomas W.; Tyner, Wallace E..
In this paper, we offer a general equilibrium analysis of the impacts of US and EU biofuel mandates for the global livestock sector. Our simulation boosts biofuel production in the US and EU from 2006 levels to mandated 2015 levels. We show that mandates will encourage crop production in both biofuel and non biofuel producing regions, while reducing livestock and livestock production in most regions of the world. The non-ruminant industry curtails its production more than other livestock industries. The numerical results suggest that the biofuel mandates reduce food production in most regions while they increase crude vegetable oils in almost all regions. Implementing biofuel mandates in the US and EU will increase croplands within the biofuel and...

Incremento en el precio del maíz y efectos sobre la oferta de carne de res a nivel de granja. Colegio de Postgraduados
Hernández Zarco, Alfonso.
La actividad pecuaria es de gran importancia socioeconómica para el país; la ganadería, en específico la producción de carne, es la actividad más diseminada en el sector rural. Se estima que la superficie aprovechada por la ganadería es superior a 110 millones de hectáreas, aproximadamente 60% del terrritorio nacional (SAGARPA, 2000). En el presente trabajo se estiman los efectos que se tiene sobre las cantidades ofrecidas de carne de res a nivel de granja ante un incremento en el precio del maíz, sorgo y pan. Los incrementos utilizados sobre los precios de los granos fueron del 5%, 10% y 15%, estos son ingredientes básicos en la dieta de bovinos. De igual manera, se realizo un cuestionario verbal con engordadores de Coatlinchan Texcoco edo. de México...

INSURING EGGS IN BASKETS AgEcon
Hart, Chad E.; Hayes, Dermot J.; Babcock, Bruce A..
The vast majority of crop and revenue insurance policies sold in the United States are single-crop policies that insure against low yields or low revenues for each crop grown on a particular farm. This practice of insuring one crop at a time runs counter to the traditional risk management practice of diversifying across several enterprises to avoid putting all of ones eggs in a single basket. This paper examines the construction of whole-farm crop revenue insurance programs to include livestock. The whole-farm insurance product covers crop revenues from corn and soybeans and livestock revenues from hog production. The results show that at coverage levels of 95 percent or lower, the fair insurance premiums for this product on a well-diversified Iowa hog...

Invasin gimB found in a bovine intestinal Escherichia coli with an adherent and invasive profile BJM
Matter,Letícia B.; Spricigo,Denis A.; Tasca,Caiane; de Vargas,Agueda C..
The invasin gimB (genetic island associated with human newborn meningitis) is usually found in ExPEC (Extraintestinal Pathogenic Escherichia coli) such as UPEC (uropathogenic E. coli), NMEC (neonatal meningitis E. coli) and APEC (avian pathogenic E. coli). In NMEC, gimB is associated with the invasion process of the host cells. Due to the importance of E. coli as a zoonotic agent and the scarce information about the frequency of gimB-carrying strains in different animal species, the aim of this study was to investigate the presence of gimB in isolates from bovine, swine, canine and feline clinical samples. PCR was conducted on 196 isolates and the identity of the amplicons was confirmed by sequencing. Of the samples tested, only E. coli SB278/94 from a...

Invasive Species Management: Foot-and-Mouth Disease in the U.S. Beef Industry AgEcon
Zhao, Zishun; Wahl, Thomas I.; Marsh, Thomas L..
A conceptual bio-economic framework that integrates dynamic epidemiologicaleconomic processes was designed to analyze the effects of invasive species introduction on decision-making in a livestock sector (e.g., production and feeding). The framework integrates an epidemiological model, a dynamic livestock production model, domestic consumption, and international trade. The integrated approach captures producer and consumer responses to, and welfare outcomes of, livestock disease outbreaks, as well as alternative invasive species management policies. Scenarios of foot-and-mouth disease are simulated to demonstrate the usefulness of the framework in facilitating invasive species policy design.

Investing in Livestock Development in Water-Scarce Semi-Arid Watersheds: Technological, Institutional and Policy Dimensions AgEcon
Puskur, Ranjitha.
Watershed Development Programmes (WDPs) in India were conceived as tools for correcting the regional imbalances in agricultural development created by Green Revolution, through investments in soil and water conservation (SWC) and natural resource management (NRM) in rainfed areas. Though the overall impact of WDPs has been positive and significant, with increase in physical and economic access to groundwater, landless and marginal households hardly benefited from watershed development. Recent evidence points out that in many watersheds inequities increased, since for non-land owning and -well owning households access to drinking water, grazing lands and other natural resources decreased. This paper is based on a research project carried out by the...

Livestock and water interactions in mixed crop-livestock farming systems of Sub-Saharan Africa: Interventions for improved productivity AgEcon
Descheemaeker, Katrien; Amede, Tilahun; Haileslassie, Amare.
Focusing on mixed crop-livestock farming systems of sub-Saharan Africa, this review brings together the available knowledge in the various components of the livestock and water sectors. Through an analysis of livestock-water interactions, promising strategies and interventions to improve Livestock Water Productivity are proposed. In the biophysical domain, the numerous interventions relate to feed, water and animal management. These are interlinked with interventions in the socio-political-economic domain. The paper identifies critical research and development gaps in terms of methodologies for quantifying water productivity and integrating different scales, and also in terms of institutions and policies.

Livestock in China: Commodity specific total factor productivity decomposition using new panel data AgEcon
Rae, Allan N.; Ma, Hengyun; Huang, Jikun; Rozelle, Scott.
Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China employing the stochastic frontier approach, and decompose productivity growth into its technical efficiency and technical progress components. Efforts are made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical innovation in...
