International audience ; Unlike in modern breeds, the knowledge on performance and management of local pig breeds is very limited. These are key aspects to be developed for their successful exploitation that requires strategies adapted to their specific productive and metabolic characteristics, quite different from those of modern pig breeds, to ensure their preservation and future expansion, particularly for those more endangered. These are some of the challenges addressed by the project TREASURE. For this purpose, a series of experiments involving 11 European local breeds -differing in the level of development- have been carried out covering various and complementary aspects like nutritional requirements in different productive phases (Cinta Senese, Iberian), feeding practices involving locally available resources (Krskopolje, Schwäbisch-Hällisches, Turopolje, Mangalitsa, Bísaro, Iberian, Gascon), and innovative management and housing practices to enhance product quality or improve animal welfare (Cinta Senese, Alentejano, Bisaro, Iberian, Mangalitsa, Moravka, Krskopolje, Schwäbisch-Hällisches, Black Slavonian). All these activities have been designed to obtain essential information to develop future productive strategies for each of the involved breeds, taking into account to obtain local high-quality products, and seeking for optimum pig performance and high animal welfare conditions in the production systems under consideration. The information provided constitutes a unique and valuable set of data for the management of these breeds and the further development of local pork chains. In some cases it is the first available data for the breeds concerned. A general overview of the developed activities will be presented highlighting some of the achievements obtained.

Autochthonous pig breeds provide products of differentiated quality, among which quality control is difficult to perform and insufficient for current market requirements. The present research evaluates the predictive ability of near-infrared (NIR) spectroscopy, combined with chemometric methods as a rapid and affordable tool to assure traceability and quality control. Thus, NIR technology was assessed for intact and minced muscle Longissimus thoracis et lumborum samples collected from 12 European autochthonous pig breeds for the quantification of lipid content and fatty acid composition. Different tests were performed using different numbers of samples for calibration and validation. The best predictive ability was found using minced presentation and set with 80% of the samples for the calibration and the remaining 20% for the external validation test for the following traits: lipid content and saturated and polyunsaturated fatty acids, which attained both the highest determination coefficients (0.89, 0.61, and 0.65, respectively) and the lowest root mean square errors in external validation (0.62, 1.82, and 1.36, respectively). Lower predictive ability was observed for intact muscles. These results could contribute to improve the management of autochthonous breeds and to ensure quality of their products by traditional meat industry chains. ; This research was funded by the European Union's Horizon 2020 research and innovation program, grant number 634476, for the project with acronym TREASURE.
