Dans un contexte d’interpellations sociales fortes adressées à l’élevage (Delanoue et Roguet, 2015), le projet ACCEPT, financé par le CASDAR sur 2014-2017, vise à permettre aux différentes parties prenantes, en premier lieu les éleveurs, leurs conseillers et représentants, de mieux comprendre les déterminants des controverses et mobilisations collectives autour de l’élevage. Une de ses actions analyse les regards croisés de la société sur l’élevage et des éleveurs sur les attentes sociétales, au travers d’enquêtes, auprès du grand public (Delanoue et al., 2017), de visiteurs lors de portes ouvertes en élevage (Grannec et Roguet, 2017), de militants d’associations et d’éleveurs. Cet article présente les résultats de l’enquête auprès des éleveurs.

Perception and account taken by livestock farmers of society’s perspectives on livestock farming

A survey was conducted among 468 livestock farmers at the agricultural exhibitions “Sommet de l’Elevage” in Auvergne and “Space” in Brittany by students of the agricultural schools of Brioude (Auvergne) and Le Rheu (Brittany). The goal was to better understand how farmers perceive the expectations / criticisms of citizens with regard to livestock farming. The survey had 43 questions, on the farmer, his farm, his perception of societal expectations regarding livestock and the measures he had undertaken to respond. On average, the farmers, including 84% of men, were 44.2 years old and had set up in agriculture 20 years ago on average. They consider animal welfare as the main concern of citizens for livestock farming, almost on equal terms with the price of products. Citizens were seen as sensitive first to housing and slaughter conditions. On the environment, the three issues that most concern citizens, according to farmers, are the pollution of water and soil, GMOs and greenhouse gases. Regarding risks to public health, half the farmers identify the use of antibiotics as the main subject of concern for citizens. Farmers rightly consider pig and poultry as being the productions the most challenged by society, for their impact on the environment, animal welfare and public health. For most farmers, social criticism generates anger, sadness or lack of motivation. Whereas one in six farmers say they are indifferent, one in nine say they are prompted to change their practices. To bring livestock farming into line with society's expectations, most rely on communication, but some consider the types of farming will also have to evolve.

Marie-Laurence Grannec (CRAB) et Christine Roguet (IFIP)., 49es Journées de la Recherche Porcine, Paris, 31 janvier et 1er février 2017, poster

Les filières d’élevages sont confrontées à d’importantes interpellations sociales. A partir d’entretiens avec les parties prenantes, Delanoue et Roguet (2015) ont classé les débats sur l’élevage, à l’échelle nationale, en quatre registres : l’impact environnemental, le bien-être animal, le risque sanitaire et le modèle de production. Au niveau local, l’analyse du déroulement de projets d’élevage révèle que la survenue de tensions est favorisée par la crainte de nuisances et que la perception des projets est impactée par trois déterminants : le type de territoire, l’image de la filière en question et la qualité des relations sociales (Grannec et al., 2017). Parmi les mesures prises par les filières animales pour améliorer leur image dans la société, les portes ouvertes sont l’occasion pour les éleveurs de présenter leur métier et pour les visiteurs de découvrir les conditions d’élevage. Cet article présente les résultats d’une enquête exploratoire réalisée par des étudiants du lycée agricole du Rheu (35), dans le cadre d’une formation-action, auprès de visiteurs lors de portes ouvertes en élevages. L’objectif était d’évaluer leur impact sur la perception de l’élevage.

Evaluation of the impact of open-days on the perception of animal husbandry by the visitors

One hundred and fifteen visitors were surveyed after an open-day in five farms presenting various animal species and systems of production. At the end of the visit, they were invited to answer questions about their socio-geographic profile, their motivations for participating in this visit, their opinion on breeding before the visit, their perception of the living conditions of animals and the environmental impact of the farm they visited, what they learned from it and the aspects judged positively or negatively. Forty percent of the visitors just wanted a family outing but 47% were searching for information about the functioning of the farms or the breeder's job (43%). Their questions were related to animal well-being more than to environmental impact. Furthermore, the positive or negative points they remembered at the end of the visit mainly concerned the animals’ living conditions. They were considered as "very good" or " rather good” by 96% of the visitors. This exploratory survey underlines some limitations of open-days to promote a social positive perception of livestock farming. First of all, they do not enable discussions to take place with very critical citizens because they mainly attract people who are favourably disposed to livestock farming. Nevertheless, by answering the visitors’ questions, they enable them to be reassured and confirm the positive vision they have of livestock farming. Half of the investigated people indicated having received useful information during the visit. A quarter of them left the farm with a better image.

Pork cuts composition measured by scanner as influenced by sex and halothane genotype

Consulter le resumé

Gérard Daumas et Mathieu Monziols, 63e International Congress of Meat Science and Technology, Cork, Irlande, 13-18 août 2017, p. 54-55

The aim of this study was to quantify the main effects influencing the tissue composition measured by computed tomography (CT) of pork cuts. A representative sample of the French pig slaughtering was selected in three abattoirs and stratified according to sex (50% castrated males and 50% females). An ear sample was analysed for Halothane gene (Hal). The left sides were cut according to the EU procedure and the four main cuts were CT scanned. Images were thresholded in order to determine muscle, fat and bone weight. Sex and Hal effects on tissues proportions were analysed by variance analysis. Interaction between sec and >Hal was never significant. Sex was significant on all the tissues proportions in the cuts, except the bone % in ham and loin. Hal was significant on all the tissueds proportions in the cuts, except the fat % in shoulder and the bone % in belly. Sex had a major effect (1 standard deviaiton) on the muscle % in the loin and the fat % in the shoulder. The important effects of sex and Hal on pork cuts composition should be taken into account by pork industry for sorting cuts and carcasses and for selecting suppliers.

Vision versus reflectance technology to estimate pork cuts composition

Consulter le resumé

Gérard Daumas et Mathieu Monziols, 63e International Congress of Meat Science and Technology, Cork, Irlande, 13-18 août 2017, p. 115-116

The objective of this article is to compare the precision of two carcass classification methods to assess the lean meat percentage (LM%) of the major pork cuts. One method is automatic by vision (CSB Image-Meater®, IM) and the other is semi-automatic by reflectance (CGM). A sample of 241 carcasses, comprising 50% of females and 50% of castrated males, was measured by both methods. The left sides were cut according to the EU procedure and the four main cuts were weighed and scanned by X-Ray tomography. Each LM% was regressed on the one hand on the two CGM thicknesses and, on the other hand, on the four IM thicknesses. The thickness M4 of IM was not significant. The hierarchy of the cuts has been preserved in therms of increasing residual standard deviation (RSD): ham, shoulder, loin and belly. The RSDrose about 15% for the limbs and 30-35% for the trunk. The help of carcass classification for directing cutting should turn out to be weakened.

Conséquences of the future EU regulation on pig carcass classification

Consulter le resumé

Gérard Daumas et Mathieu Monziols, 63e International Congress of Meat Science and Technology, Cork, Irlande, 13-18 août 2017, p. 277-278

The aim of this paper was to evaluate the main consequences of the change of the EU regulation on pig carcass classification, in particular the change of the reference lean meat percentage (LMP). A sample of 29 pigs was selected in two abattoirs and stratified according to sex (50% castrated males and 50% females). The left half carcasses as well as the four main cuts were scanned by computed tomography (CT). All cuts were then dissected. CT images were thresholded in order to determine lean meat. The future reference (LP in the carcass) will be 2.8% lowe rthan the present one (LMP in the fourmain cuts), i.E. about 1.7 percentage points. The French CT procedure could be fitted via a multiplicative factor of 0.965. This procedure is robust to the main factors - sex, genotype, fatness - influencing the classification. This would allow to use this scaling factor without new dissections for the future trials for approval of classification methods in France. It could be used too in other countries interested in this CT procedure.

NIR and VIS-NIR spectroscopy to predict PSE-LIKE zones of ham

Consulter le resumé

Antoine Vautier et al., 63e International Congress of Meat Science and Technology, Cork, Irlande, 13-18 août 2017

The aim of the study was to evaluate NitFom´s ability to predict PSE-like zones, a muscle structure defect in ham, which at present can only be detected by visual inspection after deboning. NitFom is an on-line fast device based on NIR spectroscopy dedicated to the meat industry. In comparison with the Vis-NIR Labspec4 spectrometer, the overall misclassification level of the NitFom is higher (13.0% vs 26.1%). However, misclassification of deboned ham deeply affected by PSE-like zones is lower for both devices (25% of false positives for NitFom). This level of accuracy could be satisfactory and useful for the meat industry, considering that the use of NitFom allow sorting of bone-in hams. The NitFom accuracy for PSE-like zone classification might be improved by expanding the range of spectrum analyzed by adding the visible wavelengths.

Prediction of drip loss and ultimate pH in pork Semimembranosus by the Nitfom

Consulter le resumé

Antoine Vautier et al., 63e International Congress of Meat Science and Technology, Cork, Irlande, 13-18 août 2017

Most of the NIR spectrometers available are not suited for on line measurements in slaughterhouses. The aim of the study was to test the ability of a device dedicated to industrial measurement (NitFom, Frontmatec) for prediction of drip loss and ultimate pH. A calibration model fitting was satisfactory (drip loss, R²=0.59 and pHu, R²=0.70) and the prediction accuracy levels for drip loss were similar to calibration results found with the Labspec4, a laboratory Vis-NIR spectrometer (NitFom, rmsecv=1.5% and Labspec4, 1.7%). This study revealed that prediction of drip loss by NIRS could be a good alternative to measurement of ultimate pH for drip loss sorting.

Gérard Daumas, 68th Annual meeting of the European federation of animal science (EAAP), Tallinn, Estonie, 28 août-1er septembre 2017, poster

Entire male is the alternative to pig castration chosen by some groups in Europe and in France by the leader cooperative. Since 2013 the French production of entire males has been increasing. Although the advantage in carcass composition is well known precise estimates are not easily available. Statistics per sex are regularly published by the French regional classification organisations. The aim of this work is to compare the national classification results of entire males with those of castrated males.

En élevage, l’eau d’abreuvement est fréquemment traitée par un biocide désinfectant afin d’en améliorer la qualité bactériologique. Cette eau peut également servir de vecteur d’antibiotiques.

Cependant, la compatibilité entre les biocides désinfectants et les antibiotiques est mal documentée. L’objectif de cette étude est d’évaluer la stabilité des antibiotiques en présence de désinfectants dans l’eau de boisson.

Les antibiotiques administrés aux animaux d’élevage se retrouvent en partie dans leurs déjections. Tant qu’ils sont actifs, ils peuvent favoriser le développement de bactéries résistantes dans le lisier ou ses issues destinés à être épandus sur les sols agricoles. Cette étude vise donc à analyser le devenir de polypeptides, tétracyclines, pénicillines et macrolides, au cours des étapes les plus courantes de la gestion des lisiers.

Accumulation of -hexabromocyclododecane ( -HBCDD) in muscles of fast- and slow-growing broiler

Consulter le resumé

Catherine Jondreville et al., XVIIth European Symposium on the Quality of Eggs and EGG Products, XXIIIth European Symposium on the Quality of Poultry Meat, 3-5 septembre 2017, Edimbourgh, Ecosse, abstract

Hexabromocyclodecane (HBCDD is a brominated flame retard included in some insulating materials used in livestock buildings, which has been detected in meat. The aim of the current study is to investigate the of this lipohilic contaminant in fast- (FG) and slow-growing (SG) broilers. First, an experiment involving FG and SG broilers exposed to HBCDD through feed during 42 and 82 days, respectiively, showed that breast muscle (BM, Pectoralis major) is similary concentrated in HBCDD in the two strains, while leg muscles (LM, thigh + drumstick including intermusclar fat) was 5 and 10 times more concentrated than BM in FG and SG broilers, respectively. Second, a physiogically based pharmacokinetic model was developed and validated using the previous data.
Different compartments (total and lipid weights) were represented : plasma, liver, BM  and LM, adipose tissue and the rest of the animal. After ingested HBCDD was absorbed and one part was eliminated by hepatic metabolism, it was distributed to tissues by the plasma, through a partition coefficient defined as the ratio between their respective neutral lipid concentrations. The model, calibrated for different strains and sex, will be used to assess the risk of meat contamination by HBCDD in different chicken production systems.

Vision versus reflectance technology for deviations for sex and halothane genotype in pig carcass classification

Consulter le resumé

Gérard Daumas et al. 63e International Congress of Meat Science and Technology, Cork, Irlande, 13-18 août 2017, p. 50-51

This work aims to compare the systematic deviations for sex and halothane genotype subpopulations between pig classification methods by automatic vision and semi-automatic relfectance. A sample of 209 carcasses, stratified according to sex (50% castrated males and 50% females), was measured by CSB Image-Meater® (IM) and CGM. An car sample was analysed for halothane gene (Hal). The left sides were cut according to the EU procedure and the four main cuts were weighed and scanned by X-ray tomography in order to detemrine lean meat percentage (LMP). For each device the LMP was regressed on the fat and muscle depths included in the official equations. For each equation were calculated the systematic deviations per level of the sex and Hal factors by mean difference between predicted and observed values. The LMP overestimation for castrated males increased from 0.4% with CGM to 0.7% with IM. The LMP overestimation for non-sensitive homosygotes Hal, not significant with CGM, rose to 0.5%. Systematic deviations for sexual types could be cancelled at least by a differentiated offset in the prediction equation.

Gérard Daumas et Mathieu Monziols, 63e International Congress of Meat Science and Technology, Cork, Irlande, 13-18 août 2017, p. 52-53

This work aims to quantify the systematic deviations for sex and halothane genotype subpopulations in the estimation by automatic vision of pork cuts composition. A sample of 208 carcasses, startified according to sex (50% castrated males and 50% females), was measured on line by the classification method CSB Image-Meater® (IM). An ear sample was analysed for halothane gene (Hal). The left sides were cut according to the EU procedure and the four main cuts were CT scanned  in order to determine the lean meat percentage (LMP) in each cut. These LMPs were regressed on six IM potential predictors and the carcass weight. For each equation were calculated the systematic deviations per level of the sex and Hal factors by mean difference between predicted and observed values. The absolute deviation per sexual types was the lowest (0.5%) in ham and the highest (1.4%) in belly. The deviations per Hal genotype ranged from 0.3% in shoulder to 0.8% in belly. In all models females and Hal heterozygotes were underestimated and vice-versa. The deviations per Hal genotype were about the half than per sex. The deviations per sex could be removed by at least a different intercept in the prediction equations.
