La production de porcs biologiques en France est marginale par rapport à celle des porcs conventionnels (moins de 1% en tonnage) mais en progression constante. La production porcine biologique est fortement encadrée par la réglementation qui impose des contraintes fortes en termes de logement, d'alimentation et de conduite d'élevage. Ces contraintes peuvent influencer les performances, la santé et le bien-être des animaux ainsi que la qualité des carcasses et des viandes. Les données existantes suggèrent une grande diversité des types d'élevages de porcs biologiques et in fine des conséquences du mode de production biologique sur le bien-être et la santé des animaux vivants ainsi que sur la qualité des produits. D'une façon générale, le mode de production biologique offre des atouts pour répondre à l'attente des consommateurs concernant le bien-être animal et la qualité des produits, mais les éleveurs doivent être vigilants en matière de santé des animaux, d'équilibre des rations alimentaires, surtout pour les porcelets et les truies allaitantes, et de qualité des carcasses. ; The importance of organic pig production is very low in France compared to that of conventional pigs (less than 1% of pork production) but increases regularly. Organic pig production is organised by the legislation that imposes numerous constraints in terms of housing, feeding and husbandry. These constraints are likely to influence performances, health and welfare of the pigs as well as the quality of carcasses and meat. Existing knowledge suggests a high diversity in the types of organic pig farms and hence on the consequences of the organic farming on pig welfare and health as well as on the quality of the products. Overall, organic farming offers good opportunities to respond to consumers' wishes regarding animal welfare and quality of food products provided that pig producers pay attention to animal health, nutritional balance of the diets, especially for piglets and lactating sows, and quality of carcasses.

Dry-fermented pork sausages, from Cinta Senese local breed, were manufactured replacing sodium nitrite (NIT) with two mixtures of natural antioxidants consisting of: i) grape seed extract and olive pomace hydroxytyrosol (GSE); ii) chestnut extract and olive pomace hydroxytyrosol (CHE). The effects on physical-chemical, aromatic and sensory traits, as well as the microbiological safety, were tested. Nitrite replacement lowered the pH in GSE and CHE samples and resulted in several differences in physical traits between CHE and NIT samples. Listeria monocytogenes, Salmonella and Clostridium botulinum were not found in any samples. GSE and CHE mixtures showed a slightly lower antioxidant activity. Volatile profile showed a similar aromatic profile among the three treatments with differences mainly to abundance of the single compounds, indicating that replacement of nitrite by natural antioxidants did not affect the overall aroma profile, as outlined by olfactometry results. In addition, the replacement did not affect the overall acceptability, except for color-related traits, underscored in GSE and CHE products. ; The research was carried out with funds from the European Union's Horizon 2020 research and innovation program under grant agreement No 634476 (acronym TREASURE).

Study demonstrates the preliminary results of the evaluation of pork and pork products of local Slovenian (Krškopolje) and Croatian (Turopolje) pig breeds using near infrared spectroscopy (NIRS) conducted in the frame of European Union H2020 project TREASURE. For that purpose samples from meat and products of two local pig breeds were collected, scanned with near infrared spectroscopy apparatus and chemically analysed (for proximate composition, fatty acids composition, proteolysis index, salt content and water activity). Data obtained were added to the database of previously collected samples and prediction models were recalibrated and reassessed. In general NIRS calibration models are considered to be fit for purpose when the requirements (chemometric parameters) for screening purposes are met. In the present study, the quality of recalibrations using the samples from local pig breeds confirmed practical applicability for majority of studied quality traits. Further efforts are needed to enlarge the database with additional samples from local pig breeds to improve the robustness of the models and to test the calibrations on the independent sets of samples (i.e. with external validation).

TREASURE is a research and innovation project of European Union's Horizon 2020 programme which is devoted to traditional genetic resources in pig production with aim to improve their potentials for enhanced use. Studying and improving management of local pig breeds in their production systems is one of the challenges in which we address their performances and nutrition with special attention on locally available feeding resources and innovative practices aiming to improved welfare. For that purpose 15 experiments on 12 breeds were designed in the project, which are hereaft er shortly presented. Their concepts and main objectives with some highlights on already available results are described.
