    In a simple and short-lasting pilot study it was determined whether laying hens prefer to dustbath in either small coconut fibres, grinded wheat straw, sawdust (fine) or peat moss. Peat moss has been included because it is a preferred dustbathing substrate for laying hens. The study was performed in two units on a commercial laying hen farm. In each unit, all four substrates were tested. Video recordings were made during the afternoon and analysed during four days. This pilot study indicated that an equal number of hens showed dustbathing in peat moss and coconut fibres, whereas grinded wheat straw and sawdust were hardly used for dustbathing.

    Review : Synergy between mechanistic modelling and data-driven models for modern animal production systems in the era of big data

    animal production - digital agriculture - hybridization - machine learning - mechanistic modelling

    Mechanistic models (MMs) have served as causal pathway analysis and 'decision-support' tools within animal production systems for decades. Such models quantitatively define how a biological system works based on causal relationships and use that cumulative biological knowledge to generate predictions and recommendations (in practice) and generate/evaluate hypotheses (in research). Their limitations revolve around obtaining sufficiently accurate inputs, user training and accuracy/precision of predictions on-farm. The new wave in digitalization technologies may negate some of these challenges. New data-driven (DD) modelling methods such as machine learning (ML) and deep learning (DL) examine patterns in data to produce accurate predictions (forecasting, classification of animals, etc.). The deluge of sensor data and new self-learning modelling techniques may address some of the limitations of traditional MM approaches - access to input data (e.g. sensors) and on-farm calibration. However, most of these new methods lack transparency in the reasoning behind predictions, in contrast to MM that have historically been used to translate knowledge into wisdom. The objective of this paper is to propose means to hybridize these two seemingly divergent methodologies to advance the models we use in animal production systems and support movement towards truly knowledge-based precision agriculture. In order to identify potential niches for models in animal production of the future, a cross-species (dairy, swine and poultry) examination of the current state of the art in MM and new DD methodologies (ML, DL analytics) is undertaken. We hypothesize that there are several ways via which synergy may be achieved to advance both our predictive capabilities and system understanding, being: (1) building and utilizing data streams (e.g. intake, rumination behaviour, rumen sensors, activity sensors, environmental sensors, cameras and near IR) to apply MM in real-time and/or with new resolution and capabilities; (2) hybridization of MM and DD approaches where, for example, a ML framework is augmented by MM-generated parameters or predicted outcomes and (3) hybridization of the MM and DD approaches, where biological bounds are placed on parameters within a MM framework, and the DD system parameterizes the MM for individual animals, farms or other such clusters of data. As animal systems modellers, we should expand our toolbox to explore new DD approaches and big data to find opportunities to increase understanding of biological systems, find new patterns in data and move the field towards intelligent, knowledge-based precision agriculture systems.

    The AGRI committee of the European Parliament requested EFSA to assess the welfare of rabbits farmed in different production systems, including organic production, and to update its 2005 scientific opinion about the health and welfare of rabbits kept for meat production. Considering reproducing does, kits and growing rabbits, this scientific opinion focusses on six different housing systems, namely conventional cages, structurally enriched cages, elevated pens, floor pens, outdoor/partially outdoor systems and organic systems. To compare the level of welfare in the different housing systems and rabbit categories, welfare impact scores for 20 welfare consequences identified from the literature were calculated, taking their occurrence, duration and severity into account. Based on the overall welfare impact score (sum of scores for the single welfare consequences), obtained via a 2-step expert knowledge elicitation process, the welfare of reproducing does is likely (certainty 66–90%) to be lower in conventional cages compared to the five other housing systems. In addition, it is likely to extremely likely (certainty 66–99%) that the welfare of kits is lower in outdoor systems compared to the other systems and that the welfare is higher in elevated pens than in the other systems. Finally, it is likely to extremely likely (certainty 66–99%) that the welfare of growing rabbits is lower in conventional cages compared to the other systems and that the welfare is higher in elevated pens than in the other systems. Ranking of the welfare consequences allowed an analysis of the main welfare consequences within each system and rabbit category. It was concluded that for reproducing does, as well as growing rabbits, welfare consequences related to behavioural restrictions were more prominent in conventional cages, elevated pens and enriched cages, whereas those related to health problems were more important in floor pens, outdoor and organic systems. Housing in organic rabbit farming is diverse, which can result in different welfare consequences, but the overall welfare impact scores suggest that welfare in organic systems is generally good.

    Welkom bij de cursus "Stressvrij omgaan met de koe". Als je stressvrij en makkelijk met koeien werkt, ervaar je als veehouder meer plezier. Minder stress en angst zorgen ervoor dat het welzijn van de koe toeneemt. Het gevolg is een goede algemene gezondheid en klauwgezondheid. Dit kan weer leiden tot een hogere melkgift en een betere bevruchting. Dat levert een veehouder al snel duizenden euro's per jaar op.Maar hoe krijg je dit voor elkaar? Hoe zorg je voor makkelijk vee? Wat heeft de koe nodig om rustig en voorspelbaar te zijn? Waar zie je de verschillen tussen situaties, bedrijven en mensen? En wat is jouw rol hierin?In deze cursus 'Stressvrij omgaan met de koe' combineren we kennis uit de literatuur en praktijk.

    De positie van het dier in onze maatschappij verandert. De opstelling van de mens als heerser over dieren maakt geleidelijk plaats voor een houding die gekenmerkt wordt door betrokkenheid bij dieren en acceptatie van hun eigenheid. Inbreuken op dierenwelzijn worden steeds minder geaccepteerd. We bewegen naar een nieuw verbond tussen mensen en dieren. Dat stelt de Raad in zijn rapport 'De Staat van het Dier'.
