The ED/TEG Indicator for the Identification of Endocrine Disrupting or Toxic Effects on Endocrine Glands of Crop Protection Products Used in Organic and Conventional Agriculture in France.

Studying the human health impacts of pesticides and their endocrine disruptor (ED) effects is a public health concern. The aim of this study is to identify phytopharmaceutical active substances (PAS) that are an ED or are toxic on endocrine glands (TEG), and to propose an ED/TEG effect indicator. Five international official databases were analyzed to identify the occurrence of health outcomes for 458 PAS. Health outcomes targeting seven endocrine systems were selected. For each substance, the level of evidence of the collected information and the number of outcomes were used to affect a level of concern about ED/TEG effects. Among the substances studied, 10% had a global ED/TEG effect classified as ‘high concern’, 55% as ‘medium concern’, 9% as ‘low concern’, and 26% as ‘unknown’. Ten of the high ED/TEG concern substances and 170 medium or low concern substances were licensed in 2018 in France. The outcomes were mainly on the reproductive organs, thyroid, and adrenal glands. Eight of the 41 biocontrol products studied were classified: 5 were ‘high’ or ‘medium concern’ and 3 had ‘unknown effect’. Although the proposed ED/TEG indicator is not an official classification, it can be used as an epidemiological tool for classifying the occupational and environmental risks of substances in retrospective population studies and be useful for occupational health physicians.

Offshore Wind Farms and State Aid Rules - the Case of France

The development of offshore wind farms in France raises some interesting questions related to State aids. As the electricity produced by this technology is not yet competitive on the French market, the national authorities have implemented financial support mechanisms that must be compatible with State aid rules before being granted. As the development of those projects lasts for several years, the identification of the guidelines of the Commission that shall be used to assess the compatibility of the measures regarding state aids is not an easy task. In its recent decision (2019) dealing with the support granted to 6 offshore wind farms, the Commission has applied the 2008 Guidelines. This choice is questionable and the validity of its decision could be at stake. Other questions related to state aid issues such as the choice to cover connection costs with network tariffs are also dealt with in this article.

Conventionalised vs. agroecological practices on organic vegetable farms: Investigating the influence of farm structure in a bifurcation perspective

CONTEXTAccording to the bifurcation hypothesis, a gap may be growing between “agroecological” organic farms, which rely mostly on ecosystem services, and “conventionalised” ones, which rely more on external inputs, related to contrasting evolutions in farm structure (e.g. size, specialisation) and supply chains. OBJECTIVEThe objectives of this study were to 1) analyse the diversity of organic vegetable farming systems in France, 2) investigate the extent to which bifurcation can be observed among organic vegetable farms in France and 3) investigate the extent to which structural factors that can reflect bifurcation (e.g. profiles of “new organic farmers”, marketing channels, farm size) are related to conventionalised or agroecological OF. METHODSWe developed a farm typology based on Factor Analysis of Mixed Data (FAMD) and agglomerative hierarchical clustering (AHC) using information obtained from an online survey with 165 complete answers. We used composite indexes that aggregated primary indicators to compare the biotechnical and socio-economic dimensions of farms among clusters. RESULTS AND CONCLUSIONSThe diversity that exists in organic vegetable farms, with large differences among farm clusters, can be interpreted as a snapshot sign of bifurcation, which is a temporal process, and support hypotheses that relate farming structure to farming practices in this perspective. Our study suggests that 1) the dichotomy that contrasts “agroecological” to “conventionalised” organic farms should be considered as a conceptual perspective with two poles and a gradient of farms between them; 2) farms that were created as organic tended to be more agroecological than farms that were converted from conventional farming; 3) new entrants to organic farming had the best agroecological performances; 4) the best agroecological performances were associated with short supply chains, although good agroecological performances did occur with some long supply chains; and 5) the smallest farms were more likely to implement agroecological practices, but farm size did not have the same influence on all agroecological practices. SIGNIFICANCEThese findings confirm the influence of structural factors that reflect bifurcation of the degree of conventionalisation or agroecology of organic vegetable farming. For a given set of structural factors (i.e. farmer profile, farm size and supply chain), however, agroecological performances varied greatly. This suggests levels of freedom to develop more agroecological organic practices for a given farm size or supply chain that should be further investigated.

Early exit from business, performance and neighbours’ influence: a study of farmers in France

Abstract This article investigates the effects of economic performance and neighbours’ characteristics on farmers’ exit behaviour before retirement age. Using a unique set of social security data describing all French farmers under 50 over the years 2004–2017, we explore how these effects depend on farmers’ characteristics and how they stand relative to their neighbours. Our probit estimations reveal that younger farmers and farmers operating smaller farms are more sensitive to their own and neighbours’ performance than other farmers. Allowing for an asymmetric comparison effect between farmers and their neighbours, we uncover a nonlinear influence of own and neighbours’ profit and size.

Estimation of soil water retention in conservation agriculture using published and new pedotransfer functions

Conservation agriculture has been developed as a means to improve the sustainability of agricultural systems and reduce drawbacks of conventional agricultural practices. Cropping practices can have a large influence on soil properties such as water retention. Proper tools are needed to assess and model effects of conservation agriculture on soil properties. As measuring soil water retention is expensive and time consuming, pedotransfer functions (PTFs) are now commonly used to predict them. The objectives of this study were to (i) present a new dataset of conservation agriculture data, (ii) assess performances of existing PTFs in predicting soil water retention of soils under conservation agriculture and (iii) develop new specific PTFs to predict water retention in conservation agriculture more accurately. We used data collected only in fields under conservation agriculture in France to evaluate several published PTFs with three evaluation criteria (RMSE, prediction bias (ME) and Nash-Sutcliffe Efficiency (EF)). We then developed new PTFs using three methods ― multiple linear regression, regression tree and random forest ― to predict soil water content at matric heads of -100 (θ100, field capacity for sandy soils), -330 (θ330, field capacity for other soils) and -15 000 cm (θ15 000, wilting point). Soil tillage, presence of a cover crop, rotation length and previous reduced/no tillage were used as predictors in addition to basic soil properties for regression trees and random forests. The quality of prediction (RMSE, ME and EF) was calculated for each new PTF using a cross-validation procedure. Generally, predictions of wilting point had lower absolute error than those of sandy-soil field capacity (RMSE = 0.044 and 0.066 cm3/cm3, respectively). EF was usually negative for all water contents. The cross-validation performance of the new PTFs was similar for multiple linear regression (RMSE: 0.028, ME: 0.000, EF: 0.34 for θ100) and random forest (RMSE: 0.027, ME: 0.000, EF: 0.36 for θ100), and generally worse for regression tree (especially EF). Multiple linear regression that did not consider cropping practices performed as well as random forest and thus did not identify any major influence of agricultural management on predicted water content. Future research on developing PTFs should focus on identifying more relevant predictors.

The conditions of emergence of cooperation to prevent the risk of diffuse pollution from agriculture: a case study comparison from France

Groundwater resources are essential for the supply of drinking water in the European Union but significant uncertainties surround their quality. In this context, our article analyzes the factors that influence the cooperation of key stakeholders to prevent the risk of diffuse pollution from agriculture. We built on the institutional rational choice approach and the social-ecological system framework to design our analytical framework and hypotheses. We applied this analytical framework to two cases of cooperation involving drinking water suppliers and farmers in the management of the risk of non-point source pollution from agriculture in France. Our results show that cooperation emerges when the water resource is important for water suppliers to take on the leadership. Our results also characterize the role played by uncertainties and risk in getting stakeholders involved, and finally, suggest that cooperation depends on the size and predictability of the resource system.

Latent Class Modelling for a Robust Assessment of Productivity: Application to French Grazing Livestock Farms

AbstractOur objective is to extend the latent class stochastic frontier (LCSFM) model to compute productivity change, using the robust transitive productivity Färe‐Primont index. The application is to three types of grazing livestock farms in France over the period 2002–2016. The LCSFM identified two classes of farms, intensive farms and extensive farms. Results indicate that productivity change and its components show only small differences between the LCSFM and the pooled model that does not account for heterogeneity. Differences across classes exist, but depend on farm type.

Wind farm revenues in Western Europe in present and future climate

Investments into wind generation may be hampered by revenues uncertainty caused by the natural variability of the resource, the impact of climate change on wind potential and electricity prices, and the regulatory risks. We quantify the uncertainty of the net present value of wind farms in France, Germany and Denmark and we evaluate the cost of support mechanisms needed to guarantee their profitability under present and future climate. We build a localised model for wind power output and a country-level model for electricity demand and prices taking into account hourly variation of wind, load and prices. Our study reveals that support mechanisms are needed at current market prices and current climate, as well as under future climate according to several scenarios for climate change and energy transition. The cost of support mechanisms for a 15-year period is evaluated to 57-172 billion euros in France, 232-397 in Germany, and 18-50 in Denmark.

Epidemiological and Bacteriological Investigations Using Whole-Genome Sequencing in a Recurrent Outbreak of Pullorum Disease on a Quail Farm in France.

Simple SummaryAlthough pullorum disease is endemic in many parts of the world, this avian disease responsible for high economic and commercial losses has been eliminated from organized poultry production in Europe and North America. However, it may still remain in backyards and reappear sporadically on conventional poultry farms. This study presents in detail a recurrent outbreak of pullorum disease on a quail farm. In this case report, we present how epidemiological and bacteriological investigations using molecular sequencing tools were carried out in order to identify the source of contamination. Finally, we identify high-risk sanitary practices, and propose recommendations to manage and control this poultry disease, which has become rare in European countries. Given the development of outdoor farms and the increase in self-consumption family farms, a resurgence of pullorum disease cannot be excluded in the coming years. It is essential to develop effective sanitary barriers to prevent transmission between the two coexisting populations of commercial and non-commercial poultry and to raise awareness among all those involved in the poultry industry to be able to detect any outbreak quickly.An outbreak of pullorum disease causing septicemia and high mortality was diagnosed in 2019 on a quail farm in western France. An initial episode had been detected in another building at the same site eight months earlier. Given the exceptional nature and the extent of the potential economic consequences of pullorum disease, epidemiological and bacteriological investigations using molecular sequencing tools were carried out. Salmonella Gallinarum and Salmonella Infantis were isolated (using the NF U 47-101 reference method) from samples taken from birds at the infected site. A resurgence of the initial episode by horizontal transmission of S. Gallinarum is the most likely hypothesis, supported by whole-genome sequencing (WGS) of the strains isolated during the two episodes. Risk health practices have been identified, including the rearing of animals of different ages and species on the same site. Recurrence is explained by the probable persistence of reservoirs of the pathogen on the site (manure, lesser mealworm beetles). The article also highlights the importance of decontamination measures, including pest control, as a key element in the success of the disease control protocol.

Preliminary Data from Six Years of Selective Anthelmintic Treatment on Five Horse Farms in France and Switzerland.

Simple SummaryToday, anthelmintic resistance (AR) of small strongyles (cyathostomins) against all presently available anthelmintics for equids poses on many horse farms worldwide huge problems with regard to an efficient and satisfactory parasite control. Therefore, alternative parasite control schemes are urgently needed. The so-called selective anthelmintic or targeted selective treatment (SAT) is one of the concepts considered to delay or even to overcome this challenging AR-situation. In the present field study, all 93 equids (90 horses, 3 ponies) from five horse riding farms in France and Switzerland were regularly sampled (spring and autumn) and the feces were analyzed for a period of six years. From a total of 757 fecal samples, only 263 (34.7%) had a fecal egg count ≥200 Eggs per Gram (EpG) (threshold) and consequently needed an anthelmintic treatment. A long-term reduction in the number of anthelmintic treatments can be expected on a herd and on the individual horse level, respectively, when comparing to a conventional (or strategic) twice per year treatment regime.Anthelmintic resistance (AR) of small strongyle populations (cyathostomins) against products of the benzimidazole and tetrahydropyrimidine classes occurs now worldwide and there is an increasing number of reports also regarding macrocyclic lactones. Consequently, and in order to maintain an appropriate horse parasite control, alternative control schemes must be evaluated under field conditions. Here we present a six-year field study on the administration of the so-called selective or targeted selective anthelmintic treatment (SAT) concept. In this study on five horse farms in France and Switzerland, 757 fecal samples from 93 equids (90 horses, 3 ponies) have been taken twice a year (between early and late spring and between early and late autumn) from autumn 2014 to spring 2020 and processed by a McMaster technique. From a total of 757 samples, only 263 (34.7%) had a fecal egg count ≥200 EpG and needed an anthelmintic treatment. This small number of fecal samples ≥200 EpG demonstrates the considerable potential for a long-term reduction of the number of anthelmintic treatments and the anthelmintic pressure by using the SAT-programme.

Can Small French Farms Provide an Opportunity for Employment in the Agricultural Sector?

SummaryThe contributions of small farms to the environment or employment are increasingly recognised. Yet small farm employment receives little support from public policies. Can small farms provide employment opportunities in the agricultural sector? The objective of this work is to contribute to reflections on a better adaptation of public support to the heterogeneity of the contributions of small farms to employment. This article focuses on the example of France, using the 2010 agricultural census data. It proposes a typology of workforce patterns in French small farms.In 2010, labour‐intensive small farms with paid worker(s) accounted for just over 2 per cent of small farms in France. They were managed by trained farmers, sometimes newcomers to agriculture, and had high value‐added activities like agrotourism, short distribution channels and/or organic farming production. We conclude with recommendations for European and national public policies aimed at encouraging the maintenance and/or creation of employment on small farms. They include, for example, specific support for small farms, adapted to their lower investment needs and a lighter administrative burden to enable them to develop labour‐intensive projects; or a better integration of small farms into employers’ alliances.

Natural and Experimental Persistence of Highly Pathogenic H5 Influenza Viruses in Slurry of Domestic Ducks, with or without Lime Treatment.

Infections by A/H5 and A/H7 avian influenza viruses (AIVs) can cause acute disease and are therefore notifiable in poultry and wild birds. During winter 2015-2016, several cases of infection caused by highly pathogenic (HP) AIVs belonging to the A/H5N1, A/H5N2, and A/H5N9 subtypes were detected in southwestern France. Throughout winter 2016-2017, several cases of infections caused mainly by A/H5N8 HP AIV (A/goose/GD/1/1996, clade 2.3.4.4) were detected across Europe. On both occasions, the viruses were widely detected on palmiped farms in France. This study was designed to evaluate the persistence of A/H5 HP AIV in slurry from various duck productions. This was achieved (i) in the laboratory setting by artificially spiking four AIV-free slurry samples with known amounts of A/H5N9 HP AIV and monitoring virus infectivity, with or without lime treatment to achieve pH 10 or pH 12, and (ii) by sampling slurry tanks on five naturally A/H5N8 HP-contaminated farms. Experimental results in artificially spiked slurry suggested virus survival for 4 weeks in slurry from Muscovy or Pekin duck breeders and for 2 weeks in slurry from ducks for foie gras production during the assisted-feeding period, without lime treatment. Persistence of infectious A/H5N9 HP AIV in all slurry samples after lime treatment at pH 10 or pH 12 was less than 1 week. The A/H5N8 HP AIV persisted in naturally contaminated untreated slurry for 7 weeks. The results obtained provide experimental support for the 60-day storage period without treatment or the 7-day interval after lime treatment defined in French regulations for slurry sanitization.IMPORTANCE From November 2015 to July 2017, two successive episodes of H5 highly pathogenic avian influenza viruses (HP AIVs) infections occurred on poultry farms in France, mostly in domestic ducks raised for foie gras production in southwestern France. During the two epizootics, epidemiological investigations were carried out on infected farms and control and biosafety measures were implemented in association with surveillance in order to stop the spread of the viruses. Effluents are known to be an important factor in environmental dissemination of viruses, and suitable effluent management is needed to help prevent the spread of epizootics to other farms or pathogen persistence at the farm level. The present study was therefore designed to assess how long infectious A/H5 HP AIVs can persist in naturally or experimentally contaminated fecal slurry samples from ducks, with or without sanitization by lime treatment.

Carbon footprint and economic performance of dairy farms: The case of protected designation of origin farms in France

This paper assesses the drivers of greenhouse gas emissions and economic performances for a sample of dairy farms Protected Designation of Origin dairy farms in France. Investigating caeteris paribus drivers of performance, we conclude that synergies are rare. Investing in farming equipment, optimizing fuel use or suppressing manure composting can however improve environmental performance by 5 to 13% without impairing profits. In parallel, increasing labor productivity and reducing the share of protein in the diet enhances the economic performance by 7 to 21% without increasing GHG emissions. On the debated merit of intensiveness, our analysis leans towards a negative influence of concentrates, especially protein-rich ones such as soybean cakes, both on economic and environmental performances. This result, consistent with previous studies on extensive systems, could be conditioned by a good know-how and management of grass.

Transition Pathways Toward the Prudent Use of Antimicrobials: The Case of Free-Range Broiler Farmers in France.

Reducing antimicrobial use (AMU) on farms is key for controlling the rise of resistant bacteria that have the potential capacity to infect humans via direct animal contact or via the food chain or the environment. To reduce AMU, antimicrobials must be used in a prudent and rational manner. Extensive efforts have been made recently to identify the cognitive and behavioral barriers to the appropriate use of antimicrobials by various livestock sector stakeholders. However, most studies carried out thus far have only partly captured the dynamic and systemic dimension of the processes involved in changes of practices related to AMU on farms. To shed light on the transition pathways implemented to reduce AMU, a qualitative study was conducted in France based on 28 semi-structured interviews with farmers, technicians and veterinarians from the free-range broiler production sector. Based on the thematic analysis of verbatims, we identified technical improvements which are key contributors to reduced AMU. We also highlighted some gaps in knowledge regarding AMU and antimicrobial resistance. We found that, rather than individual motivations alone, the extent to which farmers are embedded in collective organizations is decisive for changes in practices, and downstream operators (distributors and slaughterers) play a key role in the beginning of AMU transition pathways. As a result, we show that change in AMU requires a global rethinking of the overall socio-technical system rather than modifications of a single element in a farming system. Our results also highlight that transition pathways toward reduced AMU cannot just rely on trigger events, but also involves medium or long-term processes, with actors' experiences and practices being modified on an incremental basis over time. Our study sheds light on the need for multi and trans-disciplinary research involving the social sciences to analyze interactions between stakeholders and the collective actions implemented to tackle the challenge of AMU reduction.

Association of antimicrobial usage with faecal abundance of aph(3’)-III, ermB, sul2 and tetW resistance genes in veal calves in three European countries

High antimicrobial use (AMU) and antimicrobial resistance (AMR) in veal calves remain a source of concern. As part of the EFFORT project, the association between AMU and the abundance of faecal antimicrobial resistance genes (ARGs) in veal calves in three European countries was determined. In 2015, faecal samples of veal calves close to slaughter were collected from farms located in France, Germany and the Netherlands (20 farms in France, 20 farms in the Netherlands and 21 farms in Germany; 25 calves per farm). Standardized questionnaires were used to record AMU and farm characteristics. In total, 405 faecal samples were selected for DNA extraction and quantitative polymerase chain reaction to quantify the abundance (16S normalized concentration) of four ARGs [aph(3')-III, ermB, sul2 and tetW] encoding for resistance to frequently used antimicrobials in veal calves. Multiple linear mixed models with random effects for country and farm were used to relate ARGs to AMU and farm characteristics. A significant positive association was found between the use of trimethoprim/sulfonamides and the concentration of sul2 in faeces from veal calves. A higher weight of calves on arrival at the farm was negatively associated with aph(3')-III and ermB. Lower concentrations of aph(3')-III were found at farms with non-commercial animals present. Furthermore, farms using only water for the cleaning of stables had a significantly lower abundance of faecal ermB and tetW compared with other farms. A positive association was found between the use of trimethoprim/sulfonamides and the abundance of sul2 in faeces in veal calves. Additionally, other relevant risk factors associated with ARGs in veal calves were identified, such as weight on arrival at the farm and cleaning practices.

Economic optimization of feeding and shipping strategies in pig-fattening using an individual-based model

Economic results of pig-fattening systems vary greatly and depend mainly on prices of pork and feeds, and pig growth performance (e.g. feed efficiency, slaughter weight, lean percentage). Previous studies revealed that feeding and shipping strategies are critical factors in the economic outputs of pig production. However, they failed to consider both strategies and the variability in pig growth performance simultaneously. Consequently, we developed a new approach to improve the profitability of pig farms by estimating the best compromise among feeding costs, animal performance, and shipping constraints. We used an individual-based bioeconomic model that simulates the growth of each pig according to its biological traits (e.g. feed intake and protein deposition potential) as a function of different feeding and shipping strategies. The optimization problem is solved using an evolutionary algorithm (CMA-ES, covariance matrix adaptation evolution strategy) that manages the objective function, which is discontinuous, non-convex, nonlinear, and multimodal. Various case studies were constructed to investigate the behavior of the optimization procedure. Effects of pork price on optimal strategies were investigated using three different price scenarios: low (1.173 €/kg), medium (1.314 €/kg), and high (1.662 €/kg) pork prices. Optimizing only feeding strategies improved the gross margin per pig by 5.0% while optimizing shipping strategies improved the mean gross margin per pig by 4.7%. Optimizing both feeding and shipping strategies improved the gross margin per fattened pig by 10% (2.88 €/pig, with medium pork price (1.314€/kg)) compared to the common practice on farms in France. Pork price had a limited effect on feeding decisions when optimized alone, but a strong impact on shipping decisions. Economic optimization of pig fattening inconsistently affected the environmental impacts. However, increasing pork price improved the optimized mean gross margin per pig but increased all environmental impacts. To our knowledge, this is the first tool able to optimize both feeding and shipping strategies while considering effects of variability in growth potential among a batch of pigs. These features allow consideration of the interaction effect of feeding and shipping strategies on the economic outputs of the batch, and investigation of the trade-off between production cost and technical performance. This tool should interest the pig sector since it can identify the best feeding and shipping strategies depending on the economic context. Further work should consider multiobjective optimization with both economic and environmental objectives.

Contracting and Farmers’ Perception of Unfair Trading Practices in the EU Dairy Sector

AbstractIt is commonly asserted that unfair trading practices (UTPs) emerge largely as a result of contract incompleteness. In line with this view it is claimed that making contracts more complete will represent an antidote to UTPs. In this paper we argue that this does not need to be the case. This is because contracts, except for their potential to increase the surplus generated in the transaction, determine how this surplus will be divided. This, in turn, makes it possible for both trading partners to use contractual terms to turn the distributional conflict to their advantage. In the presence of unequal distribution of bargaining power this may lead to a situation in which the stronger party may succeed in tilting the contract in its favour by including UTPs in the contract content. Drawing insights from data collected in 2017 through a field survey among dairy farmers in France, Germany, Poland and Spain, we find support for this argument. Our estimation results show that contract completeness increases the likelihood of farmers reporting that their contracts with processors include the practices that may be considered as UTPs. Further, and also in line with this argument, contract completeness does not seem to affect UTPs during the contract execution or its termination.

Biosecurity risk factors for highly pathogenic avian influenza (H5N8) virus infection in duck farms, France.

Highly pathogenic avian influenza (HPAI) subtype H5N8 outbreaks occurred in poultry farms in France in 2016-2017, resulting in significant economic losses and disruption to the poultry industry. Current evidence on associations between actual on-farm biosecurity risk factors and H5N8 occurrence is limited. Therefore, a retrospective matched case-control study was undertaken to investigate the inter-relationships between on-farm biosecurity practices and H5N8 infection status to provide new insights regarding promising targets for intervention. Data were collected on 133 case and 133 control duck farms (i.e. the most affected species) located in one area of the country that was mostly affected by the disease. Data were analysed using Additive Bayesian Networks which offer a rich modelling framework by graphically illustrating the dependencies between variables. Factors indirectly and directly positively associated with farm infection were inadequate management of vehicle movements (odds ratio [OR] 9.3, 95% credible interval [CI] 4.0-22.8) and inadequate delimitation of farm and units (OR 3.0, 95% CI 1.6-5.8), respectively. Inadequate disposal of dead birds was instead negatively associated with the outcome (OR 0.1, 95% CI 0.0-0.3). The findings highlight that reinforcing farm access control systems and reducing the number of visitors are key biosecurity measures to control farm vulnerability to H5N8 infection and could help setting priorities in biosecurity practices to prevent outbreaks' re-occurrence.

Interreg 2 seas Project: Health For Dairy Cows, H4DC

Cryptosporidium spp. are microbial parasites that infect the gastrointestinal tract of humans and many animals, causing cryptosporidiosis, a disease characterised by acute watery diarrhoea. In dairy farms, C. parvum is the most common species in calves, leading to high mortality rate, stunted growth, and consequently high economic losses. Trade between farms and breeding centres is a major risk factor in the spread of such parasites, posing a threat to other farms worldwide as well as to human health. This problem is aggravated by the lack of good breeding practices, efficient detection tools, and lack of effective anti-cryptosporidial drugs. To address cryptosporidiosis in dairy farms, we have established the ‘Health For Dairy Cows (H4DC)’ consortium in order to tackle some of the aforementioned issues. Herein, we will present preliminary data from a 3-step strategy: 1)Dissemination of pilot farms in France, Belgium, The Netherlands and England. This collaboration will serve to test the effect of new husbandry practices in the occurrence of Cryptosporidium, which will aim to decrease Cryptosporidium incidence and ultimately decrease the economic burden of cryptosporidiosis. 2)These pilot farms will later be used as testing-grounds of the low-cost and easy-to-use in-situ C. parvum detection tool that will be developed during this project. 3)Development of a cell-based drug-screening system which will be used to screen various drugs and compounds for anti-Cryptosporidium activity. Finally, data from these findings will be used to establish model and strategies in order to transfer the developed technologies to both farmers and biotech/pharmaceutical companies.
