Faced with the current challenges of the climate emergency and global change, the revaluation of local products, their knowledge, consumption, and distribution is emerging as one of the strategic actions aimed at reducing the carbon footprint. Agritourism, as an activity that values everything that is related to the agricultural heritage and that enables direct contact between visitor and farmer, contributes to positioning and strengthening the local agrifood product in tourist destination areas and becomes another link in the production chains, promoting direct sales and the short distribution circuit of the products. This research aims to measure the presence of the local agrifood product in the context of agritourism developed in the Western Catalan Pyrenees (Spain). To do this, it analyses the presence of the local product and the ways used to incorporate it into the travel experience. It explores (through interviews) the opinions of the owners of agritourism farms/businesses in relation to the repercussions of the producer–consumer connection through food. To reach this goal, secondary sources are reviewed—bibliographical, statistics, and web pages—and a total of 26 interviews are carried out. In terms of the results, we highlight that in the Western Catalan Pyrenees, about 70% of agritourism accommodations include local products in their offer. Additionally, the professional project is strengthened by including the agrifood product in the offer's structure through catering and/or direct sale, generating positive dynamics among the rest of the producers in the area. However, only a small percentage of agritourism accommodations fully diversify their project with the production, consumption, and distribution of their own and local food. A total of four different profiles of agritourism are identified regarding agrifood products. [ABSTRACT FROM AUTHOR]

We study the dynamics of an infinitesimal mass under the gravitational attraction of N - 1 primaries arranged in a planar ring configuration plus the influence of the central mass with a Manev potential (-1/r +e/r²), e ≠ 0, where e is a parameter related to the oblaticity or radiation source (according to the sign of the parameter e). Specifically, we investigate the relative equilibria of the infinitesimal mass and their linear stability as functions of the parameter e and the mass parameter \beta, the ratio of mass of the central body to the mass of one of the N - 1 remaining bodies. We also prove the nonexistence of binary collisions between the central body and the infinitesimal mass. [ABSTRACT FROM AUTHOR]

ABSTRACT: At the onset of lactation in dairy cows, inflammation and oxidative stress may occur and result in a risk of pathologies and lower milk yield. To propose an innovative management strategy for cows during this period, it is essential to better understand these physiological variations. Our objective was to evaluate the metabolic, redox, and immune status of 7 primiparous and 8 multiparous Holstein cows during late gestation and the first months of lactation. Blood samples were collected between 3 wk before calving until 12 wk postpartum. Milk samples were also collected, but only at the time points after calving. The metabolic (nonesterified fatty acids [NEFA], BHB, glucose, urea, calcium) and redox (reactive oxygen metabolites [ROM], oxidative stress index [OSI], glutathione peroxidase activity, vitamin E) statuses were analyzed in plasma or erythrocytes. The expression of genes related to antioxidant functions was determined in leukocytes collected from milk. For immune status, plasma cytokine levels and the production of reactive oxygen species (ROS) in classical and regulatory neutrophils were measured in 2 whole blood ex vivo challenges. The data were analyzed using a mixed model that included the fixed effects of parity and week and their interaction. Milk yield, plasma NEFA, and BHB in wk 2 and 4 after calving were higher in multiparous cows than in primiparous cows, whereas glucose and calcium tended to be lower. Plasma ROM and OSI levels in wk 8 were higher in multiparous than in primiparous cows. Multiparous cows also displayed higher glutathione peroxidase activity in erythrocytes, and antioxidant transcription factor and superoxide dismutase-1 expression levels in milk leukocytes. Moreover, multiparous cows had higher plasma concentrations of vitamin E but lower plasma levels of cytokines CXCL10, CCL2, IL1Rα, and IFNγ. Following ex vivo whole blood stimulation with Escherichia coli, lower IL1α and TNFα levels were measured in multiparous than in primiparous cows. Intracellular ROS production by neutrophils was lower in multiparous than in primiparous cows. These results thus indicated marked physiological changes in wk 8 compared with wk 2 and 4 of lactation. These differences in the physiological status of primiparous and multiparous cows offer interesting perspectives for potential dietary strategies to prevent pathologies which take account of parity and week relative to calving.
