Mother-offspring bonding revisited: a blueprint for the future of beef cattle farming
Get PDFThis review summarizes the status of the art of cow-calf relationships at birth and during lactation, including the physiological mechanisms throughout suckling/nursing and weaning which can impact on productive and reproductive parameters, social behaviour across the mother-offspring pairs, and the required positive cow-calf welfare approach in beef cattle. The time spent close to the calf after birth, latency to nurse, nursing time, grooming and vocalisations can be considered fair proxies of oxytocin release and maternal care during the neonatal period. Besides, maternal contact during the first days after parturition will be crucial to guarantee the adequate establishment of mother-offspring bonding and the correct social and emotional development of young calf in beef cattle. During lactation, restricted nursing systems have been demonstrated as cost-effective management alternatives to improve reproductive herd performance. As artificial weaning of calves is considered a significant stressor in the lives of beef cattle, the use of a fence-line or the two-step weaning have been proposed, although no clear benefits in reducing cow-calf distress have been found. Modelling the perspective from a productive to a welfare approach in a beef cattle system is required. The ability of cows and calves to engage in voluntary, self-generated and goal-directed behaviour must be considered in the design of tailored management practices that maintain the trade-off between animal performance, cow-calf interactions, and positive mental state. Likewise, social interactions may be considered as part of environmental optimization to provide cow-calf pairs with opportunities for positive experiences and improve cattle welfare. The Five Domains Model is proposed to develop welfare-orientated management strategies considering aspects such as maternal deprivation, behavioural stress and socio-emotional development in beef cattle. This holistic approach of mother-offspring bonding focused on nutrition (Domain 1), physical environment (Domain 2), health (Domain 3), behavioural interactions (Domain 4) and animal’s mental state (Domain 5) will help to improve management decisions and cow-calf welfare state. Some management recommendations and opportunities for future studies to deeply enlarge the welfare perspective in the dyad are discussed.La investigación fue apoyada por las becas EC AIR3-CT94-1124, INIA RZP 2004-08 e INIA RTA 2005-0231 (del Ministerio de Ciencia, Innovación y Universidades de España y los Fondos Europeos de Desarrollo Regional) y el Grupo de Investigación A11 "Sistemas Agro-silvo-pastoriles", Gobierno de Aragón, España) / Research was suported by the grants EC AIR3-CT94-1124, INIA RZP 2004–08 and INIA RTA 2005-0231 (from the Ministry of Science, Innovation and Universities of Spain and the European Regional Development Funds) and the Research Group A11 “Agro-silvo-pastoral Systems”, Government of Aragon, Spain).Publishe

Utility of stabilized nitrogen fertilizers to reduce nitrate leaching under optimal management practices
Get PDFBackground:The inadequate application of nitrogen (N) to crops has increased the reactive N in the atmosphere and in the surface and ground waters. Stabilized N-fertilizers with nitrification (NI) and urease (UI) inhibitors have been proposed to reduce these environmental problems without affecting or even increasing crop productivity. Aim:The objective of this study was to evaluate, in a maize-maize-wheat rotation, if the use of the NI 3,4-dimethylpyrazole phosphate (DMPP) and the UIs N-(n-butyl) thiophosphoric triamide (NBPT) and monocarbamide dihydrogen sulfate (MCDHS) reduces N leaching without compromising yield under optimal management of N and water. Methods:The experiment was conducted in 24 drainage lysimeters with two soil types with contrasting water holding capacity under Mediterranean irrigated conditions. The fertilizer treatments were urea, urea with DMPP, urea with NBPT, and urea with MCDHS. For the maize crop, conventional fertilizer application was split into 6- and 13-leaf stages, whereas stabilized fertilizers were applied as a single application at the 6-leaf stage. All fertilizer treatments were applied at late tillering in the wheat crop. Results:The soil mineral N was measured at the beginning and the end of each crop season, but no differences were found among fertilizer treatments. Differences in the volume of water drained or the cumulative mass of nitrate depending on the fertilizer were not significant (three-year treatment average of 200 L m(-2)and 22 kg N ha(-1)in the Deep soil, and 334 L m(-2)and 40 kg N ha(-1)in the Shallow type, respectively). No consistent significant differences were found in agronomic parameters (chlorophyll measurements, yield, and total N uptake) between the fertilizer treatments. Conclusion:Based on the results, the use of stabilized N-fertilizer could be recommended to reduce the number of N applications in maize without compromising grain yield but with no advantages to reduce nitrate-leaching losses if N rates are managed properly under efficient irrigation management practices.This study was funded by the Spanish Ministry of Economy,

Necesidades de fertilización nitrogenada de la vid: estudio global a través de un metanálisis
Get PDFPara asegurar un adecuado aporte de nitrógeno que satisfaga simultáneamente los objetivos de producción y calidad vitivinícola, así como de sostenibilidad ambiental, se realizan numerosos ensayos de fertilización nitrogenada a lo largo del mundo. Sin embargo, hasta ahora no se había realizado ningún trabajo de análisis conjunto de estos ensayos que permitiera extraer resultados globalmente representativos sin efectos de confusión por diferencias de clima, suelo, material vegetal, manejo, etc. En consecuencia, se llevó a cabo un metanálisis sobre los efectos de la fertilización nitrogenada sobre la producción y calidad de uva para vinificación, cuyos aspectos principales se presentan en este trabajo. Se encontró que para maximizar la producción se necesitan entre 30 y 40 kgN/ha, mientras que para promover la calidad se requieren entre 20 y 25 kgN/ha. Estos valores permitieron establecer recomendaciones de abonado nitrogenado de la vid como función lineal del potencial hídrico de tallo al mediodía. Estas recomendaciones se han integrado en el Sistema de Apoyo a la Decisión WANUGRAPE4.0.El presente trabajo forma parte de los proyectos de I+D+i con referencia PDC2021–121210–C21 y PDC2021–121210–C22, financiados por MICIN/

The Effect of Information on Willingness to Pay for Canned Tuna Fish with Different Corporate Social Responsibility (CSR) Certification: A Pilot Study
Get PDFThe objective of this study was to assess the role of information in consumers' willingness to pay (WTP) for food products with corporate social responsibility (CSR) certification. The item used for the experimental design was canned tuna fish, a product on the market that is already exhibiting various kinds of certification related to social and environmental attributes. Two different kinds of certifications were examined, namely Friend of the Sea, which involves environmental aspects, and SA8000, related to workers' rights and more general social attributes. We implemented experimental auctions, taking into account three information treatments. The initial findings show that the WTP for both CSR labels is higher than the WTP for tuna fish without any CSR certification. Nevertheless, the information provided on CSR certification did not change consumers' WTP among the certification schemes. Our findings could also serve to fine-tune marketing strategies to consumer preferences and determine which CSR activities are worth undertaking.Publishe

Xylem and phloem in petioles are coordinated with leaf gas exchange in oaks with contrasting anatomical strategies depending on leaf habit
Get PDFAs the single link between leaves and the rest of the plant, petioles must develop conductive tissues according to the water influx and sugar outflow of the leaf lamina. A scaling relationship between leaf area and anatomical traits of xylem and phloem is expected to improve the efficiency of these tissues. However, the different constraints compromising the functionality of both tissues (e.g., risk of cavitation) must not be disregarded. Additionally, plants present two main leaf habits (deciduous and evergreen) that may have different strategies to produce and package their petiole conduits to cope with environmental restrictions. In this study, we explore, in a diverse group of 33 oak species, the relationships between petiole anatomical traits, leaf area, stomatal conductance and photosynthesis rate. Results showed allometric scaling between anatomical structure of xylem and phloem with leaf area. We also found how photosynthesis and stomatal conductance at leaf-level are correlated with anatomical traits in the petiole. Nonetheless, the main novelty is how oaks present a different strategy depending on the leaf habit. Deciduous species tend to increase their diameters to achieve a greater leaf-specific conductivity. By contrast, evergreen oaks develop larger xylem conductive areas for a given leaf area than deciduous ones. This trade-off between safety-efficiency in petioles has never been attributed to the leaf habit of the species.Esta investigación ha sido financiada por la subvención PID2022-631 136478OB-C32 financiada por MICIU/AEI/10.13039/501100011033 y por «ERDF A way of making Europe», por la subvención CNS2022-136156 financiada por MCIN/AEI/10.13039/501100011033 y European Union Next Generation EU/PRTR y por el grupo de investigación S74_23R del Gobierno de Aragón.QuercusConductive TissuesLeaf HabitPetiolesWater RelationsXylem TransportUnpublishe
