Reduce antibiotic use is a major issue for pigs production because of World Health Organization recommendations and meat consumers concerns.
In order to reduce the needs of medication, one way is the early individual disease detection for isolate and treat only the sick animal. The subclinical
symptoms with the feeding and drinking behaviour can have a diagnostic value. A first automatic warning system has been built based on a statistic model who use data from automatic feeders, connected bowl drinker and connected scale.

Livestock farming systems and the French society: key controversies

Consulter le resumé

Elsa Delanoue, sociologue (Idele, Ifip, Itavi), 70th Annual Meeting of the European Federation Animal Science (EAAP), 26-30 août 2019, Ghent, Belgique, p. 614

For several years, French livestock farming has been frequently questioned by society. Those questions concern its environmental impact, sanitary risks or animal treatment and ask, more generally, livestock farming’s place among a society that is more and more concerned about its alimentation. To understand this phenomenon, analyse representations on livestock farming that coexist within the society and enlighten agricultural actors on those social evolutions at work, the project ACCEPT, funded by the CASDAR and led by the French Pork and Pig Institute (IFIP), has been carried out between 2014 and 2018. With the aim of identifying the subjects of controversy about breeding in France, all animal productions considered, and to describe the diversity of actors and arguments, both qualitative and quantitative studies were conducted: around seventy interviews were conducted, in France and five other UE countries, with the main stakeholders (livestock farming professionals, farmers, companies, journalists, NGOs, consumers) and more than 2007 French citizens were questioned on a online survey. The analysis of discourses led to classify the debates on the French livestock farming in four major areas: environmental impact, animal welfare, risks to human health and socioeconomic model of livestock farming. It reflects expectations for different types of system: some want a gradual disappearance of intensive farming systems for the benefit of under official quality signs or implementing alternative practices; others want the development of intensive farming to produce more and become more competitive; and between them many want a gradual improvement in the intensive system, with stronger environmental and animal welfare requirements. We consider that we face a global controversy on livestock farming: indeed, beyond specific controversies on practices, debates regarding the very legitimacy of livestock farming or the consumption of animal products gather all the different topics, and are linked with larger society problematics (consumption habits, growth models, globalization, etc.). This feature may complicate the resolution of the controversy and make it hazardous and longer.

Development of a quantative PCR method coupled with PMA to quantify viable Salmonella spp. cells in the pork supply chain

Consulter le resumé

Sabine Jeuge et al., 13e SafePork, 26-29 août 2019, Berlin, Allemagne

In 2017, Salmonella spp. was implied in 30% of foodborne diseases in France (SPF, 2019). Few data on the contamination levels of Salmonella spp., are available along the pork supply chain. The protocol of the standard method (ISO/TS 6579-2:2012) is time-consuming and culture-based methods using chromogenic media are less efficient for matrices with high levels of back ground flora, and for recovering stressed cells. Along the food chain, the cells may be impacted by various stresses (e.g. chemical or thermal), which may lead to physiological changes and the emergence of viable but non-culturable cells (VBNCs).

Salmonellosis is a major cause of foodborne outbreaks caused by bacteria in Europe. In 2014, the European Commission reinforced the survey of this contaminant in the pig and pork industry by the competent authority. In this context, French General Directorate for Food required a new system to centralize regulatory own-checks results for Salmonella in pig carcasses.

Solène Lagadec (CRAB) et al., 70th Annual Meeting of the European Federation Animal Science (EAAP), 26-30 août 2019, Ghent, Belgique, p. 484, poster

Livestock contributes to the emission of particles in the atmosphere. Literature shows drastic differences between emission factors by animal category related to the measurement methodologies applied. Based on this observation, a project involving research and development organizations has been developed in order to develop a measurement protocol strictly adapted to pig building conditions. The project is organized in 3 steps: (1) identification of specific conditions related to pig building; (2) analysis of metrology equipment able of adapting to these conditions; and (3) development of a protocol adapted to the equipment identified in the previous step. Conclusions of the first step (1) are the following ones: ammonia concentration inside piggery vary between 0 and 50 ppm, relative humidity between 70 and 100% and temperature between -10 and +40 °C. TSP, PM10 and PM2.5 should be measured continuously in the ambience, in the extracted duct and outside. Massic concentrations but also concentration in number of particles per volume unit should be measured. In order to analyse morphology of particles, sampling should be possible.
Analysis of measurement equipment – step (2) – led to choose the optical measurement methodology applied in the GRIMM 1.109 (Intertek). Nevertheless, in order to validate collected data, gravimetric method with simple filter will also be applied. For particle measurements, 24 h sampling period should be achieved in the middle of the corridor (1-1.50 m high). This duration has been chosen in order to integrate diurnal and nocturnal changes inside piggeries.
To calculate the emission factor per fattening pig, three periods (between 14-18 days, 45-50 days and 78-82 days) were identified for measuring particles. The project is currently in progress with the second phase consisting of the implementation of this protocol in commercial pig farms in Western France.

Monitoring antimicrobial usage in pig farms is a key element of a reduction plan. The objective of this study was to analyse the antimicrobial usage evolution in the same farms between 2010-2013-2016 and to identify the factors of variations. The study monitored antimicrobial usage by weight group in 2016 in 33 farrow-to-finish farms in the West of France. The antimicrobial usage had ever been registered twice for 23 of them in 2010 and 2013 and once for 10 of them in 2013. It was quantified by the number of Course Doses per produced pig per year (nCD/pig). Farmers were asked about the factors that could explain the evolution between 2013-2016. On average, antimicrobial usage significantly decreased over six years (-38%). However, a high variability of individual evolutions was observed: among the 23 farms with three annual data, 43% decreased their use between 2010-2013 (-3 nCD/pig on average) but had a stable use between 2013-2016 (-0,2 nCD/pig). 26% decreased their use between 2010-2013 (-4 nCD/pig on average) and also between 2013-2016 (-2 nCD/pig). 9% increased then decreased their use during the two periods (+4 then -7 nCD/pig). One farm had the opposite trajectory (-9 then +2 nCD/pig) and another always increased its use (+2 then +5 nCD/pig). Among the 33 farms with data in 2013-2016, 36% decreased their use (-2 nCD/pig on average), 39% had a stable use and 24% increased their use (+3 nCD/pig). For sows, suckling piglets and fattening pigs, most of the farms had stable usage between 2013-2016. Only antimicrobial usage for weaned piglets was more frequently reduced. Increases were explained by occurrence of sanitary problems (mainly urogenital, digestive and respiratory problems on sows, piglets and fatteners respectively). Decreases were explained by vaccination, stop of preventive treatments and improvement of herd management. This study highlights the variability of individual trajectories in antimicrobial usage, due to sanitary issues that may be different according to each weight group. It usefully complements the monitoring of average evolution at the country level.

Early disease detection is one of the key to effective disease control in farms and reducing antibiotics usage. A batch of 153 weaned piglets was used to test a first machine learning algorithm in order to predict the individual health state of each animal. In order to build the early disease detection algorithm, nine boxes of 17 piglets has been set up with automata. In real time within this section we knew the number of times each animal went to the drinker or the feeder, the quantity of water and feed it took and its weight. As the golden standard to know either a piglet seems healthy or not, the clinical signs will be observed by trained operators on each pig every workday and recorded on a standardized grid (diarrhoea, cough, lameness…). Then, data collected from this batch of 153 piglets were used to create an algorithm with the software R, based on bagging and random forest machine-learning method. The database was split into learning (70%) and testing (30%). We obtained a global success of 86% of good prediction. 
In order to validate the accuracy of the model, a second batch of 153 piglets was used. Every day, a list of predicted sick pigs was printed automatically, indicating the individual identification of the animal, and its pen. Then, the results of these predictions were compared with the golden standard (observations of clinical signs by trained operators). Out of 3,437 observations (including predictions that the piglet is not sick), the algorithm correctly predicted the status of the piglets 2,462 times. Artificial intelligence has made 72% of good predictions. Regarding the true positive results, 96 alerts out of 117 were actually associated with observations of animals suffering mainly
from diarrhoea within two days (82% of success). Now, the aim is to improve this algorithm in different ways: to test accelerometers to check the activity of each piglet; to be more accurate on recording cough by a microphone (SOMO, Soundtalks); to test if some trajectories of behavioural change are linked to specific diseases (lameness, digestive or respiratory disease) and not only to generic disease. These studies will be part of the Healthylivestock project (EC funded H2020 research project).

The objective was to test the effects of a positive biofilm formation on the surfaces of post-weaning piglet facilities.
In total, 494 piglets were used in two experiments using a sanitary challenge. 48 h (d-2) before introduction of piglets, 2 identical rooms of 14 pens were sprayed either with water (Control) or a mix (LP) of selected bacteria strains.
Rooms were exchanged between Exp.1 and Exp.2. In Exp.1 rooms were sprayed again at d 15 and in Exp.2 at d 5, 12, 19, 26 and 33. Environmental challenge for piglets was stronger in Exp.1 than in Exp.2. Wiping samples indicated significantly (P<0.05) higher loads of aerobic bacteria (Lactobacillus spp., Bacillus spp.) in LP pen surfaces in Exp.1 at d 0, 5, and 14 and at d 0, 5, 7 and 35 in Exp.2, suggesting the development of the positive biofilm. Percentage of piglets with regular consistency of faeces was continuously higher in LP rooms in Exp.1 (from d 8 to 21) and Exp.2 (from d 5 to 28). Furthermore, mean scores were significantly improved at d 8 in Exp.1 (3.13 vs 4.50; P<0.01) and in Exp.2 at d 9 (2.19 vs 3.19; P=0.01) and 28 (2.03 vs 2.50; P<0.01). Disease outbreaks occurred two days later in Exp.1 (d 9 vs 7) and five days later in Exp.2 (d 12 vs 7) in LP rooms. However, total numbers of deaths from diarrhoea were similar in both treatments in Exp.1 and 2. In Exp.1, LP piglets had numerically better overall ADFI (794 vs 781 g/d; P>0.10) and ADG (510 vs 499 g/d; P>0.10), and had slightly higher weight at d 42 (29.8 vs 29.4 kg; P>0.10). In Exp.2, ADFI (259 vs 219 g/d; P<0.001) and ADG (211 vs 154 g/d; P<0.001) were significantly increased in the LP treatment in phase 1 (d 0 to 15). Weight was significantly higher for LP piglets at d 15 (11.9 vs 11.0 kg; P<0.001), although it was similar at d 41 (P>0.10). In conclusion, the spraying of a beneficial flora on surfaces may result in a protective positive biofilm that would help the piglets to deal better with the weaning challenges.

Control of biotrickling filter efficiency on NH3 emitted by piggeries

E. Dumont (IMT Atlantique) et al., 70th Annual Meeting of the European Federation Animal Science (EAAP), 26-30 août 2019, Ghent, Belgique, p. 319, poster

Ammonia emitted by piggeries can be removed using biotrickling filtration. As ammonia is a very soluble compound in water, removal efficiency (RE) around 70-80% can be expected. However, the accumulation of nitrogen salts in water leads to a decrease in RE. Consequently, there is need to improve the management of equipment by controlling the amount of water which has to be discharged and replaced by fresh water in order to limit the accumulation of nitrogen salts. Such an improvement is based on the knowledge of the nitrogen mass balance between the gas phase and the liquid phase. The objective of this study was to establish the nitrogen mass balance of a pilot-scale biotrickling filter treating ammonia emitted by a pig house. The experiment was carried out for 14 weeks on a French pig farm.
The biotrickling filter installed to treat the polluted air generated by 54 fattening pigs was filled with a structured plastic packing WAT NET 150 NC 20/48 (0.9×0.9×0.45 m). The airflow rate was of 1,350 m3/h corresponding to an Empty Bed Residence Time (EBRT) of 1 s. In the gas phase, temperature, relative humidity, ammonia and nitrous oxide concentration were hourly measured. In the liquid phase, temperature, pH, electrical conductivity, and concentration of nitrogen salts (NH4+, NO2-, NO3-) were weekly measured. Results showed that nitrogen mass balances carried out on both phases are in agreement (5% difference). A steady transfer rate of ammonia from the gas phase to the liquid phase was obtained (3.22 gN/h corresponding to 10.0 gN/pig/week). From the measured concentrations of nitrogen salts in the liquid phase, it was calculated that the nitrogen mass transfer was 9.5 gN/ pig/week. Moreover, it was also evidenced that the amount of nitrogen salts dissolved in water could be correlated to the water conductivity. As a result, the measurement of this parameter could be a useful tool to determine the amount of ammonia removed from the gas phase.

Nathalie Quiniou et al., 70th Annual Meeting of the European Federation Animal Science (EAAP), 26-30 août 2019, Ghent, Belgique, p. 414, poster

A model has been used to assess both direct and indirect consumption of energy by growing pigs fed ad libitum, housed in fattening rooms with various insulation characteristics, and under different outdoor temperatures. This model combines a growth model and a bioclimatic model. It simulates thermal exchanges at the room level, based on interactions between the insulation of the room, available equipment (fans, heaters…), the parameters of the climate control box, the characteristics of pigs, and the feeding strategy. Heat sources are the animals (sensible heat) and heaters when available. Heat losses are due to insulation characteristics of the room and air renewal. The model has been evaluated from data collected simultaneously on pigs, diets, indoor and outdoor temperature (T) during a trial, and the error of prediction of indoor T was below 0.5 °C on an hourly basis. Thereafter, simulation will be performed, based on the same population of pigs and feeding strategy under different outdoor T, different heater powers in the room combined with different insulation level of wall material. For this purpose, four time series of outdoor T have been collected over 12 months (one in France and three from South to North in Sweden), as well as building characteristics in both countries (heater power: from 0 to 26 Watt/fattening place; 1 or 3 insulated layers).

For each combination of climate and building, indoor T and pig performance will be simulated as well as total energy consumption and its partition between direct and indirect components. This research was part of the Pigsys ERA-Net project, co-funded under European Union’s Horizon 2020 RI program (from SuSan, www.era-susan.eu,Grant Agreement n°696231) by the French ANR (grant n°ANR-16-SUSN-0003-02).
