Swine manure post-treatment technologies for pathogenic organism inactivation
Provedor de dados: 70
Autores: Bilotta,Patrícia; Kunz,Airton.
Swine manure agricultural use is a common practice in Brazil. Their physic-chemical characteristics favor its use as biofertilizer, but the presence of pathogens may become a risk to human health. This research presents a qualitative study of the main alternatives of pig manure disinfection, analyzing efficiency, advantages and limitations of each procedure. The disinfection studies reported in literature are based on the following treatments: alkaline, thermal, biological, chemical, and physical. The greater efficiencies are in thermal treatment (&gt; 4 log: 60 °C), chemical treatment (3 to 4 log: 30mg Cl- L-1; 3 to 4 log: 40 mg O3 L-1) and physical treatment (3 a 4 log: 220 mJ UV radiation cm-2). The biological treatment (anaerobiosis) also promotes the...

Development of the shrimp industry in the Western Indian Ocean - a holistic approach of vertical integration, from domestication and biosecurity to product certification
Provedor de dados: 5
Autores: Le Groumellec, Marc; Rigolet, Vincent; Panchayuthapani, Duraisamy; Vandeputte, Marc; Rao, Vemulapalli Manavendra.
The shrimp farming industry in the western Indian Ocean started with Aqualma’s project in 1989, and now several companies farm shrimp in the Mozambique Channel. Despite the remoteness of these projects and their high investment and operating costs, they compete in the global marketplace by efficiently producing high value quality products. To address sustainability and biosecurity issues, Aqualma developed domesticated specific pathogenfree (SPF) broodstock of Penaeus monodon from western Indian Ocean stocks, which have been its exclusive source of post-larvae since 2003. Specific molecular diagnostic tools have been developed for each endemic pathogen detected since 1996, and these are used for routine surveillance of Aqualma’s shrimp stocks along with...

During a survey of Phytophthora diversity in natural ecosystems in Taiwan six new species were detected. Multigene phylogeny based on the nuclear ITS, ß-tubulin and HSP90 and the mitochondrial cox1 and NADH1 gene sequences demonstrated that they belong to ITS Clade 7a with P. europaea, P. uniformis, P. rubi and P. cambivora being their closest relatives. All six new species differed from each other and from related species by a unique combination of morphological characters, the breeding system, cardinal temperatures and growth rates. Four homothallic species, P. attenuata, P. flexuosa, P. formosa and P. intricata, were isolated from rhizosphere soil of healthy forests of Fagus hayatae, Quercus glandulifera, Q. tarokoensis, Castanopsis carlesii,...

A Case Control Study of Bovine Viral Diarrhea Virus (BVDV) Persistent Infection (PI) in Betsukai, Hokkaido, Japan
Provedor de dados: 19
Autores: KADOHIRA, Mutsuyo; TAJIMA, Motoshi; 門平, 睦代.
The Betsukai town office implemented bovine viral diarrhea virus (BVDV) preventive activities (i.e., vaccination and surveillance) in 2006. Using bulk tank milk screening followed by individual blood tests using a Reverse Transcription-Polymerase Chain Reaction (RT-PCR) method, persistent infection (PI) cattle were detected and eliminated from the population. Based on data for PI cattle detected between 2006 and 2007, we conducted a case control study to find risk factors associated with the presence of PI cattle. Significantly associated farm level factors for increasing risk of producing PI cattle include; 1) no recent purchase of cattle (between 2004 and 2007) and 2) no prevention of people/animals entering the premises. This study suggests that not...

Impact de la proliferation massive des upogebia dans le canal d'alimentation sur la biosecurite d'une ferme de crevette ( cas de l'aqualma - Besalampy)
Provedor de dados: 20
Autores: PATRICK, Voriasy.
Depuis l’assec du canal d’alimentation en 2004 après le passage du cyclone Gafilo, on a constaté une augmentation massive de la densité d’Upogebia spinimanus au sein de la ferme de l’AQUALMA-Besalampy. En cas d’apparition d’une nouvelle maladie des crustacés, ce phénomène constituerait un grand risque en favorisant sa transmission chez les crevettes élevées, voire les consommateurs. Une nouvelle méthode d’approche installée par le laboratoire centrale de l’AQUALMA s’intéresse sur la prévention des risques de maladie liée à la biosécurité, en même temps des crevettes, des consommateurs et de l’environnement. Par conséquent, durant ce 5 mois de stage, des pratiques sur terrain et en laboratoire au moyen de différentes expériences à noter le suivi...

Animal Disease and the Industrialization of Agriculture
Provedor de dados: 31
Autores: Hennessy,   David A.; Wang,   Tong.
The industrialization of animal agriculture has fundamentally transformed animal health markets while animal health innovations have promoted this industrialization. The subtlety of these interactions shows how little we know about agricultural industrialization. To illustrate, we consider three stylized features of industrialized animal agriculture. These are the closing off of production activities from external effects, emphasis on control, and use of biosecurity measures. We find that animal disease externalities should lead to higher stocking on any given farm, and also to deficient entry into animal production. Eradicating the disease in a region increases both the stocking rate per farm and the number of farms. We show that antibiotics as a control...

Benefit cost analysis is a tried and tested analytical framework that can clearly  communicate likely net changes in social welfare from investment decisions to  diverse stakeholder audiences. However, in a plant biosecurity context, it is often  difficult to predict policy benefits over time due to complex biophysical interaction between invasive species and their hosts. In this paper, we demonstrate how benefit cost analysis remains highly relevant to biosecurity decision-makers using the example of a plant pathogen targeted for eradication from banana growing regions of  Australia, banana bunchy top virus. We develop a partial budgeting approach using a stratified diffusion spread model to simulate the likely benefits of eradication to the banana...

A new biosecurity investment decision framework to promote more efficient biosecurity policy
Provedor de dados: 31
Autores: Smith,   Harley; Webster,   Stewart.
Australian governments spend millions of dollars each year on pre border, border and post border biosecurity programs. While the resourcing of some of these programs is determined by existing deeds of agreement, others, particularly in relation to environmental and social pests and diseases, fall outside of existing decision frameworks. This paper presents a new biosecurity investment decision framework based on economic principles that aims to produce more objectively determined decisions. It determines whether a role for government exists in relation to a specific problem through the application of market failure tests and then guides the user to the most efficient cost recovery mechanism. The framework is presently under active consideration for use by...

Area-Wide Management of Fruit-Flies: What are the Costs and the Benefits?
Provedor de dados: 31
Autores: Florec,   Veronique; Sadler,   Rohan; White,   Benedict.
Increasing volumes and speed of agricultural trade and the opening of new markets for agricultural products create greater challenges to systems established to protect countries from invasive organisms that can be harmful to human and animal health, crops and natural environments. In reaction to the threat of exotic pests and diseases, the World Trade Organization recognises the right of country members to protect themselves from the risks posed by exotic pests and diseases through the application of Sanitary and Phytosanitary (SPS) measures. One possible response from exporting countries facing SPS trade barriers is to obtain pest-free area (PFA) certification. While large benefits can potentially be achieved from greater access to world markets through...

Contracts for Grain Biosecurity and Grain Quality
Provedor de dados: 31
Autores: Abougamos,   Hoda; White,   Benedict; Sadler,   Rohan.
The export of grain from Western Australia depends upon a grain supply network that takes grain from farm to port through Cooperative Bulk Handling receival and storage sites. The ability of the network to deliver pest free grain to the port and onto ship depends upon the quality of grain delivered by farmers and the efficacy of phosphine based fumigation in controlling stored grain pests. Phosphine fumigation is critical to the grain supply network because it is the cheapest effective fumigant. In addition, it is also residue free. Unfortunately, over time, common stored-grain pests have evolved to develop resistance to phosphine and there is a risk that phosphine will become less effective and may need to be replaced with more expensive alternative...

Optimal Control of Spreading Biological Invasions: For How Long Should We Apply the Brake?
Provedor de dados: 31
Autores: Carrasco,   Luis Roman; MacLeod,   Alan; Knight,   John D.; Baker,   Richard; Mumford,   John D.
Identifying the optimal switching point between different invasive alien species (IAS) management policies is a very complex task and policy makers are in need of modelling tools to assist them. In this paper we develop an optimal control bioeconomic model to estimate the type of optimal policy and switching point of control efforts against a spreading IAS. We apply the models to the case study of Colorado potato beetle in the UK. The results demonstrate that eradication is optimal for small initial sizes of invasion at discovery. High capacity of the agency to reduce spread velocity for several years leads to smaller total overall costs of invasion and makes eradication optimal for larger sizes of initial invasion. In many cases, it is optimal to switch...

Autores: Ambarawati,   I Gusti Agung Ayu; Prasetyo,   Bugie Kurnianto; Patrick,   Ian.
This paper measures the cost of implementing biosecurity on broiler and layer farms in Bali. Farmer investment in biosecurity is analysed to determine if there is any difference in the implementation of biosecurity between broiler and layer farms. Data is taken from a survey of 60 layer and 60 broiler smallholder farmers in Bali in 2009. While secure boundary fencing and farm gate locks are more common on layer farms, broiler producers are more likely to have a footbaths at the shed door. In this analysis, biosecurity investments include the quality of fencing and gates, presence of locks on gates, management changes required to minimise staff and visitor movement onto and in the farm, costs of minimising vehicle entry, use of vaccination and disinfectant,...

Coordinating to Eradicate Animal Disease, and the Role of Insurance Markets
Provedor de dados: 31
Autores: Hennessy,   David A.
Farmed animal production has traditionally been a dispersed sector. Biosecurity actions relevant to eradicating infectious diseases are generally non-contractible, and might involve inordinately high transactions costs if they were contractible. If an endemic disease is to be eradicated within a region, synchronized actions need to be taken to reduce incidence below a critical mass so that spread can be contained. Using a global game model of coordination under public and private information concerning the critical mass required, this paper characterizes the success probability in an eradication campaign. As is standard in global games, heterogeneity in private signals can support a unique equilibrium. Partly because of strategic interactions, concentrated...

Re-examining the economic options for import risk assessments
Provedor de dados: 31
Autores: Adamson,   David; Cook,   David C.
The economic impacts of altering quarantine policies are divided into two main areas: trade evaluations, utilising a partial equilibrium approach to determine the benefits of market liberalisation; or pest management economics, used to determine the on-ground impacts of introduced species. This paper rationalises why these approaches need to be brought together within the policy framework of import risk assessments to provide a greater understanding of the benefits and risks from market liberalisation.

Economic Aspects of Agricultural and Food Biosecurity in the United States
Provedor de dados: 31
Autores: Hennessy,   David A.
Concerns about biosecurity in the food system raise a variety of issues about how the system is presently organized, why it might be vulnerable, what one could reasonably do to better secure it, and the costs of doing so. After presenting some facts about US agriculture and food, this paper considers three economic aspects of the general problem. One is the global problem, or the way biosecurity measures can affect how countries relate to each other and the global consequences that result. Another is how to best manage the immediate aftermath of a realized threat in order to minimize damage. The third is how to seek to prevent realization of the threat. Some policy alternatives are also presented.

Autores: Nunn,   Mike J.
Australia’s very good animal health status faces a wide range of biosecurity challenges that will arise during the next decade from changes in disease risk, ecosystems, technology and the policy environment in which animal producers operate. An understanding of these challenges should help enable producers to adopt management strategies to make their enterprises more resilient, as well as help policy-makers make better-informed choices to maintain and improve the health of Australia’s animals and animal industries.

Using involvement to understand responses to biosecurity
Provedor de dados: 31
Autores: Bewsell,   Denise; Bigsby,   Hugh R.; Cullen,   Ross.
The effectiveness of biosecurity measures at national borders is influenced by the behaviour and levels of involvement of travellers. Involvement is the importance or relevance of an object or situation to an individual. Involvement helps regulate the way in which people receive and process information and thus influences the extent of information searching for decision making, and information processing and persuasion. In this study, we drew on the concept of involvement to investigate the response of individuals to New Zealand biosecurity requirements. A range of people associated with the agricultural and food processing sectors were surveyed using a five item scale of involvement to measure their level of involvement in biosecurity. The results...

Behavioral Incentives, Equilibrium Endemic Disease, and Health Management Policy for Farmed Animals
Provedor de dados: 31
Autores: Hennessy,   David A.
We develop a dynamic capital valuation model in which each farm can take an action with farm-varying cost to increase the probability of not contracting a disease. In the presence of infection externalities, circumstances are identified under which multiple equilibria exist and where the one involving the most extensive set of action takers is socially optimal. It is suggested that costly capital markets are one factor in determining the extent of endemic disease in a region. The introduction of frictions, such as dealing with a cumbersome veterinary public health bureaucracy, can enhance social welfare by encouraging precautionary biosecurity actions. Some technical innovations can reduce social welfare. The model is also extended to study a voluntary...

Establishing a benefits transfer database for biosecurity decision making an indigenous biodiversity
Provedor de dados: 31
Autores: Bell,   Brian A.; Cudby,   Charlotte; Yap,   Michael.
An imbalance of quantitative information on pest and disease impacts hampers biosecurity decision-making; there is relatively good information about impacts on industry, but relatively poor information about how society values the impacts on indigenous biodiversity. A benefits transfer process based on a database of choice experiments could help to redress this imbalance. This paper: briefly reviews four choice experiments that will be the foundation of a database; reviews benefit transfer literature; and sets out framework ideas for a Decision Support System (DSS), which will incorporate biodiversity values via a process for benefit transfer to facilitate more informed biosecurity decisions.

Autores: Bell,   Brian A.; Menzies,   Sharon; Yap,   Michael; Kerr,   Geoffrey N.
This paper reports on a case study to establish dollar values for loss of biodiversity in the New Zealand coastal marine environment. The study uses the European Shore Crab (Carcinas maenas) as the example alien invasive species and the Pauatahanui Inlet, Wellington, New Zealand, as the ecosystem representative of the coastal marine environment. Choice modelling is the stated preference tool used to elicit marginal dollar values for these various attributes of the inlet. Reallocation of existing government expenditure is used as the payment mechanism. Results indicate a wide range of dollar values for the marginal losses to the environment, with no clear trend on a distance-decay relationship. The probability distributions of the dollar values of the...

Technical Barrier Effects of a Food Safety Measure – a Case of Finnish Salmonella Control Program
Provedor de dados: 31
Autores: Niemi,   Jyrki S.; Peltola,   Jukka; Simola,   Antti.
In this paper, indirect costs of Finnish Salmonella Control Program (FSCP) due to its trade effects are evaluated. FSCP is a part of Finnish biosecurity policies intended to shield Finnish food supply and consumption chain from salmonella outbreaks. The program directly increases costs of importing by e.g. requiring costly certificates for imports. Additionally, it may cause anxiety to suppliers of imports as there are added uncertainties in the import process. As similar requirements apply to domestic suppliers, the program should not be thought of as a technical trade barrier (TBT), however, it may affect trade flows indirectly and effects may be assessed in a similar manner as those of TBT’s. The evaluation of the trade effects is performed using a...

Measuring the benefits of farm animal health
Provedor de dados: 31
Autores: Stott,   Alistair W.; Brulisauer,   Franz; Fraser,   Fiona; Gunn,   George J.
A methodology is described to establish the relative financial benefit of farm animal disease prevention (biosecurity). This methodology is demonstrated using the example of bovine viral diarrhoea virus (BVDV) incursion on beef suckler farms in Scotland. A random sample of 276 herds was taken and a proportion of young stock on each farm tested for previous exposure to BVDV. There was evidence that 0.4 of herds had been exposed over one year prior to sampling. All herds completed a questionnaire about their biosecurity practices. The influence of these practices on relative risk of BVDV was subjected to a Chi squared test and practices ranked accordingly. Most important risk factors were animal buying in strategy, farm size and a single farm boundary. The...

SWINE '95 PART II: REFERENCE OF 1995 U.S. GROWER/FINISHER HEALTH AND  MANAGEMENT PRACTICES
Provedor de dados: 31
Autores: Bush,   Eric J.
This report is the second of a three-part release of national information from the second National Animal Health Monitoring System (NAHMS) swine study, the Swine '95 Grower/Finisher. The 1990 National Swine Survey focused on farrowing sows and preweaning piglets. For the Swine '95 Study, the USDA's National Agricultural Statistics Service (NASS) collaborated with Veterinary Services (VS) to select a producer sample that was statistically designed to provide inferences to the nation's swine population. Data collected for the study represented the top 16 pork states and nearly 91 percent of the U.S. hog inventory, as well as nearly three fourths of the nation's pork producers. Data for this report were collected from 418 producers whose operations had 300 or...

A Rule of Thumb for Controlling Invasive Weeds: An Application to Hawkweed in Australia
Provedor de dados: 31
Autores: Kompas,   Tom; Chu,   Long.
We use a bang-bang optimal control model to derive a rule of thumb for an optimal management of invasive weeds, in terms of the marginal benefits and costs of various control actions. Instead of determining the size of infestation under an optimal surveillance measure, the rule specifies the types of land where an invasive weed should be first prevented from establishment, and under what conditions control should be initiated. The types of land are modeled via the heterogeneous vulnerability of land to the weed and likely infestation. This easy-to-use rule is applied to determine how hawkweed should be controlled in Australia, across three potential control strategies: containment, eradication and no action. We investigate this rule-of-thumb in both...

Economies of Feedlot Scale, Biosecurity, Investment, and Endemic Livestock Disease
Provedor de dados: 31
Autores: Hennessy,   David A.
Infectious livestock disease creates externalities for proximate animal production enterprises. The distribution of production scale within a region should influence and be influenced by these disease externalities. Taking the distribution of the unit costs of stocking an animal as primitive, we show that an increase in the variance of these unit costs reduces consumer surplus. The effect on producer surplus, total surplus, and animal concentration across feedlots depends on the demand elasticity. A subsidy to smaller herds can reduce social welfare and immiserize the farm sector by increasing the extent of disease. While Nash behavior involves excessive stocking, disease effects can be such that aggregate output declines relative to first-best. Disease...

The Costs of Biosecurity at the Farm Level: the Case of Finnish Broiler
Provedor de dados: 31
Autores: Siekkinen,   K.-M.; Heikkila,   Jaakko; Tammiranta,   N.; Rosengren,   H.
In the European Union, the animal health and food safety strategy includes managing biosecurity along the entire production chain. Farm-level biosecurity provides the foundation for this. However, the farm-level costs of preventive biosecurity have rarely been assessed. Yet many risk management practices are in place constantly regardless of whether there is a disease outbreak or not. We contribute towards filling this information gap by studying the costs incurred in preventive biosecurity by the Finnish poultry farms. In a preliminary analysis, we find that the cost of biosecurity is some 3.55 cents per bird for broiler producers and 75.7 cents per bird for hatching egg producers. The results indicate that work-time devoted to biosecurity represents some...

Valuing indigenous biodiversity in the freshwater environment
Provedor de dados: 31
Autores: Bell,   Brian A.; Yap,   Michael; Cudby,   Charlotte.
Biosecurity incursion response decisions require timely, high quality information involving science and economics. The value of the impact on indigenous biodiversity is a key aspect of the economics typically involving cost-benefit analysis. The hypothetical incursion of Biosecurity New Zealand’s top priority weed hydrilla (Hydrilla verticillata) in a typical New Zealand lake (Lake Rotoroa otherwise known as Hamilton Lake) elicits dollar values of impacts on indigenous biodiversity in a freshwater environment. Using the stated preference tool, Choice Modelling, the experimental design was maximised for efficiency of Willingness to Pay (WTP) estimation. The survey method of community meetings of four population samples at varying distances to the incursion...

Allocating Vote: Biosecurity - Towards an "Economics-Based" Approach for Setting Priorities for the Importation of Risk Goods
Provedor de dados: 31
Autores: Ryan,   Michael.
The New Zealand government (through its agency the Ministry of Agriculture and Forestry, MAF) seeks to mitigate the potential negative impacts of importation through requiring commodities that may pose a risk to New Zealand's primary production systems, human health, indigenous flora, fauna or biodiversity to have an import health standard. Given, potential import opportunities exist in a wide variety of commodities from many different countries, the demand for import health standards far outweighs MAF's available resources to develop them. Therefore MAF must have a framework that prioritises which import health standards will be developed. This paper briefly presents the framework MAF is currently using to undertake the prioritisation of import health...

Security Analysis for Agroterrorism: Applying the Threat, Vulnerability, Consequence Framework to Developing Countries
Provedor de dados: 31
Autores: Linacre,   Nicholas A.; Koo,   Bonwoo; Rosegrant,   Mark W.; Msangi,   Siwa; Falck-Zepeda,   Jose Benjamin; Gaskell,   Joanne; Komen,   John; Cohen,   Marc J.; Birner,   Regina.
In some developing countries the potential exists for agroterrorism to cause widespread disruption through loss of sustenance, income and production. Defense of agriculture may also be problematic because of the lack stability and basic biosecurity infrastructure for the detection and prevention of diseases or invasive species. Currently new methodological approaches for terrorism risk assessments are being actively explored for resource prioritization. One such methodology for risk based allocation of resources is Threat, Vulnerability, and Consequence (TVC) Analysis. A qualitative application of the TVC framework is used to analyze the risk of agroterrorism in developing countries relative to industrialized countries. The analysis suggests that evidence...

Epidemiology of Avian Infectious Laryngotracheitis with Special Focus to South America: an update
Provedor de dados: 89
Autores: Parra,SHS; Nuñez,LFN; Ferreira,AJP.
ABSTRACT Avian Infectious laryngotracheitis (AILT) is a respiratory tract disease of great importance because it causes significant economic losses in the poultry industry around the world. It is caused by a Gallid herpesvirus type 1, a member of the genus Iltovirus. The target system for Avian Infectious Laryngotracheitis virus (AILTV) infections is the respiratory system, and the main organ in which the virus remains latent is the trigeminal ganglia. However, the virus has demonstrated tropism for other organs besides the respiratory tract. The main transmission routes are ocular and respiratory. Infected birds with clinical symptoms are main sources of transmission, but birds with latent infections, litter, and contaminated fomites may also transmit the...

Infectious laryngotracheitis: a review
Provedor de dados: 89
Autores: Hidalgo,H.
Infectious laryngotracheitis (ILT) herpesvirus continues to cause outbreaks of respiratory disease in chickens world-wide. Sporadic cases of ILT occur in all classes of birds, including hobby/show/game chickens, broilers, heavy breeders, and commercial laying hens. These epornitics of ILT tend to occur where there are large populations of naïve, unvaccinated birds, i.e., in concentrated areas of broiler production. ILT virus can be transmitted through (a) chickens with acute upper respiratory tract disease, (b) latently infected "carrier" fowls, and (c) fomites and contaminated persons. Chicken flocks which are endemic infected with ILT virus occur only in some regions of countries or even in particular multiple-age production farms. In these cases...

ABSTRACT The objective of this study was to investigate the influence of two cleaning and disinfection programs on broiler performance and on the microbiological status of the facilities. This trial was an observational study of comparative character. Two experiments were conducted, with 960 birds each. Both experiments were carried out in a positive-pressure broiler house. Broilers were distributed in pens equipped with a bell drinker and a tube feeder each. In the first experiment, new wood shavings were used as litter material, and in the second, reused wood shavings were used. Two treatments with16 replicates of 30 birds each were evaluated. The regular treatment consisted of dry and wet organic matter removal, followed by washing. The European...

Design and validation of a mobile air filter testing laboratory for animal agricultural applications
Provedor de dados: 111
Autores: Smith, Benjamin; Ramirez, Brett; Hoff, Steven; Harmon, Jay; Stinn, John.
The US swine industry is shifting towards filtered fresh-air ventilation systems that use pleated filters to improve breeding herd health and reduce airborne disease outbreak frequency. Loaded filters reduce airflow causing a poor environment and elevated energy use. Typical axial fans cannot efficiently maintain the rated differential pressure (DP; 100 Pa) for pleated filters; hence, a lower design filter DP (37 Pa) is used and consequently, more filters are required to achieve design maximum ventilation. Large, common filter banks for multiple staged fans presents significant challenges in using continuous DP measurement to assess filter life, making it impossible to separate filter loading DP from overall airflow DP. A mobile air filter testing (MAFT)...

This study aimed to develop a Geographic Information System (GIS), for storage of information and geographic location of apiaries in eight counties in western Paraná; study the local flora; the land used; and the honey productivity in the harvest of 2010 in two of these areas: Marechal Cândido Rondon and Santa Helena. In order to do so we used the software SPRING, delimiting a radius of action of bees of three kilometers around the apiaries. We interviewed and registered 126 beekeepers with 383 apiaries. By using the images we selected areas with greater and lower overlap of hives in Marechal Cândido Rondon (144 and 44 hives, respectively) and Santa Helena (165 and 40 hives, respectively), in a three kilometers radius, selecting 15 colonies in each area,...
