L'intĂ©rĂȘt des races mixtes dans les systĂšmes laitiers : enseignements du projet BlueSel
La « Bleue Mixte » (BM) est une race Ă petit effectif localisĂ©e de part et dâautre de la frontiĂšre franco-belge. MenacĂ©e de disparition, elle bĂ©nĂ©ficie dâun projet transfrontalier BlueSel soutenu par le programme europĂ©en INTERREG IV et les autoritĂ©s françaises et wallonnes. Lâobjectif de ce projet est dâassurer la conservation, la sĂ©lection et la promotion de la BM. Lâun des volets du programme a consistĂ© Ă Ă©tudier la rentabilitĂ© Ă©conomique des troupeaux BM. Il sâest appuyĂ© sur un rĂ©seau de 16 fermes de rĂ©fĂ©rences mis en place fin 2008 jusque mi 2012. La collecte des donnĂ©es techniques et Ă©conomiques sur les 4 annĂ©es comptables de 2007 Ă 2010 a reposĂ© sur la mĂ©thodologie mise en oeuvre au sein du dispositif français des RĂ©seaux dâĂ©levage. Les exploitations BM ont Ă©tĂ© regroupĂ©es selon deux systĂšmes, herbivore et polyculture-Ă©levage, et comparĂ©es aux exploitations laitiĂšres PrimâHolstein (PH) du RĂ©seau dâĂ©levage de Nord-Picardie. Les rĂ©sultats dĂ©montrent la capacitĂ© des Ă©leveurs de vaches BM Ă obtenir de bonnes performances Ă©conomiques malgrĂ© de plus faibles productivitĂ© laitiĂšre (4225 l/VL) et taux (3,70 % de MG et 3,22 % de protĂ©ines), et un moindre prix du lait, grĂące notamment Ă une conduite de troupeaux bien maĂźtrisĂ©e, des surfaces fourragĂšres trĂšs bien valorisĂ©es, et la mixitĂ© lait-viande trĂšs affirmĂ©e de la race qui attĂ©nue les fluctuations du prix du lait. En systĂšme herbivore, les exploitations BM sâavĂšrent Ă©conomes et autonomes avec une excellente valorisation des prairies. En systĂšme de polyculture-Ă©levage, les troupeaux sont conduits de façon Ă peine plus intensive quâen systĂšme herbivore, contrairement aux troupeaux PH.BlueSe

Acute assessment of subjective appetite and implicated hormones after a hypnosis-induced hallucinated meal: a randomized cross-over pilot trial
The use of hypnosis can generate hallucinatory phenomena, which ranged from vivid/auditory imagery to fully developed âhallucinationsâ in selected people. The aim of this pilot trial was investigating the acute effects of a hypnosis-induced hallucinated breakfast (HB) compared to those of a real breakfast (RB) on subjective appetite and appetite-regulating hormones in highly hypnotizable individuals. Eight healthy post-menopausal women were recruited to consume two meals: the HB and the RB in a randomized crossover design. Participants underwent appetite sensations measurements (before meal and each 30-min until 270-min) and blood sample collection (at 0, 20, 60, 90, 180-min). A 3-day food-record was filled after each meal. The adjusted repeated measures ANCOVA did not show any mealĂtime interactions on subjective appetite postprandially. As expected, significantly higher glucose (p < 0.001), insulin (p < 0.001), and lower free fatty acid (p < 0.001) concentrations were found after the RB, but not following HB. Furthermore, RB significantly increased postprandial levels of glucagon-like-peptide-1 and peptide-YY at 20, 60, 90 and 180-min, whereas acylated-ghrelin and leptin levels did not differ. Postprandial neuropeptide-Y and orexin-A values significantly increased at different time-points after RB, but not following HB, while α-melanocyte-stimulating hormone levels enhanced after HB only. Energy intakes were significantly lower after HB on the test-day only (HB = 1146.6 ± 343.8 vs RB = 1634.7 ± 274.2 kcal/d; p = 0.003). Appetite sensation might be modulated by fully developed meal âhallucinationâ induced by hypnosis, likely affecting brain-peptides implicated in the appetite regulation. However, further studies are needed to verify these results obtained in a highly selected group of individuals. NCT03934580
