| The objective of this work was to select surviving breeders of Litopenaeus vannamei from white spot syndrome virus (WSSV) outbreak, adapted to local climatic conditions and negatively diagnosed for WSSV and infectious hypodermal and hematopoietic necrosis virus (IHHNV), and to evaluate if this strategy is a viable alternative for production in Santa Catarina, Brazil. A total of 800 males and 800 females were phenotypically selected in a farm pond. Nested-PCR analyses of 487 sexually mature females and 231 sexually mature males showed that 63% of the females and 55% of the males were infected with IHHNV. Animals free of IHHNV were tested for WSSV, and those considered double negative were used for breeding. The post-larvae produced were stocked in nine... |

| As part of the National Animal Health Monitoring System (NAHMS ), USDA:APHIS:Veterinary Services conducted a national study of beef production, the Beef Cow/Calf Health and Productivity Audit (CHAPA). This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. The National Agricultural Statistics Service (NASS) collaborated with USDA:APHIS:VS to select a producer sample that was statistically designed to provide inferences about the nation's cow/calf population. Data for Part IV: Beef Cow/Calf Breeding Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between July 1 and July 30, 1993. These 18 states... |

This study was designed to provide both participants and the industry with information on cow/calf health, productivity, and management practices. Data for Part III: Beef Cow/Calf Health & Health Management were collected by federal and state veterinary officers (VMO's) in 18 of the largest cow/calf producing states between January 4 and February 28, 1993. These 18 states represented 70 percent of the U.S. beef cow inventory. Participating producers had five or more beef cows or beef replacement heifers and fifty percent or more of their 1992 calf crop... |

| The National Animal Health Monitoring System (NAHMS) is sponsored by the USDA:APHIS:Veterinary Services (VS). The NAHMS Equine '98 Study was designed to provide information about the nation's equine population. Twenty-eight states were included in the study. The USDA's National Agricultural Statistics Service (NASS) collaborated with VS to select a statistically-valid sample such that inferences could be made to all equids and operations with equids in the 28 states. For the purposes of the study, equids included domestic horses, miniature horses, ponies, donkeys/burros, and mules. For Part III of the study, data were collected by Federal and State Veterinary Medical Officers and Animal Health Technicians between March 16, 1998, to April 10, 1998, from... |

| This report presents a modeling framework in which epidemiological model results are integrated with an economic model of the U.S. agricultural sector to enable estimation of the economic impacts of outbreaks of foreign-source livestock diseases. To demonstrate the model, the study assessed results of a hypothetical outbreak of foot-and-mouth disease (FMD). The modeling framework includes effects of the FMD episode on all major agricultural products and assesses these effects on aggregate supply, demand, and trade over 16 quarters. Model results show a potential for large trade-related losses for beef, beef cattle, hogs, and pork, though relatively few animals are destroyed. The swine and pork sectors recover shortly after assumed export restrictions end,... |

| The need for timely collection and analysis of epidemiological data is becoming of primary importance, e.g., for bioterrorism detection or epidemiological surveillance. Web-based information systems (WISs) may provide the needed technological support. Thus we present the WeeW (workflow-enabled epidemiological WIS) system—i.e., a WIS that helps epidemiologists, through workflow management, to effectively select remote centers, collect, and process the received data to produce conclusive technical reports. In detail, we show the functionalities of the WeeW system, its architecture, and particularly Stata’s role in executing statistical analyses and producing graphs. Furthermore, we discuss the performance of the WeeW–Stata interface. Finally, we outline... |

| This paper examines the economics of farm decisions to prevent and control infectious livestock disease. In the case of diseases with costly control tolerating some level of disease is often rational to the producer. Public policy intervention is based on future value and public good aspects of disease control which can lead to a discrepancy between private and public action thresholds. Producer incentives for disease management can be changed through new technologies that lower the cost of prevention or control, subsidies or cost sharing of control measures, or on the consumer side, a change in public desire for disease risk-free products that changes relative prices. Economists can incorporate appropriate epidemiology of a given disease in economic... |
