Abstract. In the last decades, a global warming trend was observed. Along with temperature increase, modifications in humidity and wind regime amplify regional local impacts on livestock husbandry. Direct include occurrence of climatic stress conditions. Europe, cows are economically highly relevant mainly kept naturally ventilated buildings that most susceptible to climate change. The high-yielding particularly vulnerable heat stress. Modifications housing management main measures taken...
Synthetic nitrogen (N) fertilizer and field application of livestock manure are the major sources ammonia (NH3) volatilization. This N loss may decrease crop productivity subsequent deposition promotes environmental problems associated with soil acidification eutrophication. Mitigation measures have side effects such as decreased (e.g. if is reduced), or release other reactive compounds N2O emissions incorporated). Here, we present a novel methodology to provide an integrated assessment best...
Gas emissions from broiler production have been the subject of intensive research. However, little experimental information exists for farms under particular management and environmental conditions European Mediterranean area. In this study, ammonia, carbon dioxide, methane, nitrous oxide concentrations were measured in a commercial farm located Spain. using photoacoustic gas monitor, whereas ventilation flow was evaluated by controlling operation status each fan. Two rearing periods...
Broiler production in modern poultry farms commonly uses mechanical ventilation systems. This requires an amount of electric energy and a high level investment technology. Nevertheless, broiler is affected by periodic problems mortality because thermal stress, thus being crucial to explore the efficiency. In this article, we analyze cross-mechanical system focusing on air velocity distribution. way, two methodologies were used indoor environment livestock buildings: Computational Fluid...
Heat stress plays a role in livestock production warm climates. conditions impair animal welfare and compromise the productive reproductive performance of dairy cattle. Under heat conditions, cattle modify their behavior. Thus, assessment behavior alterations can be an indicator environmental or physiological anomalies. Moreover, precision farming allows for individual constant monitoring behavior, arising as tool to assess welfare. The purpose this study was evaluate effect on cows using...
Abstract Understanding the environmental consequences associated with dairy cattle production systems is crucial for implementation of targeted strategies emission reduction. However, few studies have modelled effect tailored mitigation options across key European systems. Here, we assess single and combined six practises on selected case Europe through Sustainable Integrated Management System Dairy Production model. This semi-mechanistic model accounts interacting flows from a whole-farm...
European dairy cattle production systems (DPS) are facing multiple challenges that threaten their social, economic, and environmental sustainability. In this context, it is crucial to implement options promote the reconnection between crop livestock as a way reduce emissions enhance nutrient circularity. However, given sector's diversity, successful implementation of these lacks an evaluation framework jointly considers climatic conditions, farm characteristics, manure management mineral...
In this paper we develop a mathematical model combined with machine learning techniques to predict shade-seeking behavior in cows exposed heat stress. The approach integrates advanced features, such as time-averaged thermal indices and accumulated stress metrics, obtained by analysis of data from farm Titaguas (Valencia, Spain), collected during the summer 2023. Two predictive models, Random Forests Neural Networks, are compared for accuracy, robustness, interpretability. Forest is...
Among the factors influencing dust production on farms, animal activity is probably least studied. Animal strongly affected by circadian rhythms and it altered rearing conditions, especially management of light feeding strategy. In this study, a broiler flock was evaluated until 35 d age with general objective studying dust, particularly effect activity, as lighting program. an experimental room, 2 daily dark periods 6 4 h 158 birds divided in 12 groups, reared wood shavings, were evaluated....
Carbon dioxide balances are useful in determining ventilation rates livestock buildings. These need an accurate estimation of the CO(2) produced by animals and their litter to determine flows. To estimate daily variation flow, it is necessary precisely know pattern production, which mainly depends on animal activity. The objective this study was explore applicability for flows broiler More specifically, work aimed quantify amount litter, as well broilers, a function productive parameters,...
The microclimatic conditions in dairy buildings affect animal welfare and gaseous emissions. Measurements are highly variable due to the inhomogeneous distribution of heat humidity sources (related farm management) turbulent inflow (associated with meteorologic boundary conditions). selection measurement strategy (number position sensors) analysis methodology adds uncertainty applied technique. To assess suitability different sensor positions, situations where monitoring direct vicinity...
Defining the composition and properties of manure in livestock production is critical order to minimise possible environmental impacts stemming from its management. In this study, a nitrogen balance was carried out during two identical fattening periods (Experiments 1 2) growing rabbits weaning (age 28 d live weight about 0.6 kg) slaughter 61 1.8 kg). The breeding conditions were typical for Spanish rabbit production. objectives quantify total excreted by animals estimate average efficiency...
Milk production in Europe is facing major challenges to ensure its economic, environmental, and social sustainability. It essential that holistic concepts are developed the future sustainability of sector assist farmers stakeholders making knowledge-based decisions. In this study, integrated assessment by means whole-farm modelling presented as a valuable approach for identifying factors mechanisms could be used improve three pillars (3Ps) context an increasing awareness economic...
