In de praktijk wordt dit op heel verschillende manieren ingevuld. Het verstrekken van ruwvoer aan leghennen is een geschikte manier om aan verschillende welzijnsdoelen invulling te geven. Het verstrekken van ruwvoer draagt bij aan een betere verdeling van hennen over het huisvestingssysteem, biedt hennen een functionele, en qua tijd substantiële, extra tijdsbesteding aan en kan een positieve bijdrage leveren aan het functioneren van het maagdarmstelsei van de hen. Ruwvoerverstrekking is ook voor de gangbare bedrijfsvoering interessant. Het aanbieden van ruwvoer aan gezonde hennen had positieve effecten op ontwikkeling en gedrag, ook in de opfok. Hierbij werd echter vastgesteld... Tipo: Book chapter Palavras-chave: Feeding and growth; Health and welfare; Poultry. Ano: 2011 URL: http://orgprints.org/20789/1/2541.pdf Practical implications of increasing 'natural living' through suckling systems in organic dairy calf rearing Organic Eprints Wagenaar, Jan-Paul; Langhout, Jos. The introduction of suckling systems in organic dairy calf rearing has the potential to enhance animal welfare in terms of ‘natural living’ and to live up to consumers’ expectations about organic agriculture. This study describes the implications of suckling systems in a practical organic dairy context. Results show that farmers can successfully develop and implement a suckling system in calf rearing. The consumption of mothers’ milk resulted in high weaning weights at 3 months of age. No immediate animal health problems linked to suckling systems occurred. Compared with traditional bucket feeding of milk, suckling systems resulted in increased natural behaviour such as calf cow bonding, natural sucking behaviour and care-taking behaviour. Some farmers... Tipo: Journal paper Palavras-chave: Dairy cattle; Feeding and growth.

Organic Eprints Spoolder, Hans; Biavati, Bruno; Borgsteede, Fred; Davies, David; Klocke, Peter; Maurer, Veronika; Nagel, Philip; Nicholas, Phillipa; van Krimpen, Marinus; Mejer, Helena; Modesto, Monica; Strozzi, Gian Paolo; Thamsborg, Stig Milan; Vermeer, Herman; Wagenaar, Jan-Paul; Zollitsch, Werner; Sundrum, Albert. The QLIF project has targeted a variety of issues to make organic animal production (dairy cattle, pig, poultry) more safe, develop alternative methods to promote animal health and improve product quality. This workshop will discuss these aims as well as the QLIF achievements to date. It will also address our way of assessing the quality of our organic farms. We ask the question what the advantages are of doing this by looking at the output of a farm, such as yield, animal welfare and environmental issues. Alternatively, we also want to know what benefits there are in looking at how the farm is organised, via input factors such as housing design, nutrition, management quality. Two invited speakers will state their preference. Legislation, certification and... Tipo: Conference paper, poster, etc. Palavras-chave: Health and welfare.

Farm-level factors that could be associated with feather pecking of layers kept in organic farming systems were monitored in 63 flocks from 26 farms located in different areas of The Netherlands. Data on housing and management practices were collected and plumage damage as a measure of feather pecking was scored at 50 weeks of age or older. No or little plumage damage was found in 18 (29%) flocks, moderate damage in 12 (19%) flocks and severe damage in 33 (52%) flocks. A high percentage of hens in the flock using the outdoor run, a young age at purchase and an increasing number of cockerels present in the flock were found to significantly decrease feather pecking damage at 50 weeks or older. Factors associated with increased usage of the outdoor run were... Tipo: Journal paper Palavras-chave: Health and welfare; Poultry.

Generell sind die Richtlinien für die Kälberaufzucht in der biologischen Milchviehhaltung minimal. Säugesysteme haben potentielle Vorteile bezüglich Gewichtszunahme, Wertsteigerung von Milch und Tieren, die andernfalls ausgesondert werden müssten sowie Tiergerechtheit und Natürlichkeit. Die Vorteile der Aufzucht von Kälbern mit Kontakt zur Mutter können genutzt werden, während die Nachteile solcher Systeme durch die Verwendung von Ammenkühen reduziert werden können.

Leverbotinfecties zijn in toenemende mate een knelpunt in de diergezondheid van melkvee en andere herkauwers. Door de complexe infectiecyclus, weinig inzetbare geneesmiddelen, geringe beschikbare diagnostiek en incomplete terugkoppeling van informatie (afkeur lever), kan leverbot de gezondheid negatief beïnvloeden waardoor ook vaak productieverliezen kunnen optreden. Voor vee dat melk produceert voor menselijke consumptie zijn nagenoeg geen middelen meer toegestaan om leverbot te bestrijden. Resistentie tegen de beschikbare middelen, indien diercategorieën wel behandeld mogen worden, neemt toe. Veehouders hebben behoefte aan kennis en mogelijkheden ter preventie van leverbotbesmettingen, en aan alternatieven voor een effectieve bestrijding van de leverbot...

This report was presented at the UK Organic Research 2002 Conference. This paper positions experiential science as a new discipline in science with its own characteristics and principles. New elements in experiential science are the recognition of unique patterns in relation to previous actions and the reflection on intuitive, unique actions. There is a need for a new vocabulary to develop experiential science as a novel discipline. Tipo: Conference paper, poster, etc. Palavras-chave: Research methodology and philosophy.

Since 2009 a small scale breeding and selection project started on a biodynamic farm in The Netherlands. The overall goal is to breed stronger hens that do well under organic conditions and show lower rates of mortality and at the same time have roosters that can be reared for meat production. In this paper results concerning egg and meat production are given, as well as thoughts about economic aspects. Tipo: Conference paper, poster, etc. Palavras-chave: Breeding and genetics; Poultry.

In semi-natural grasslands, plant diversity has shown to correlate with increased primary production and reduced weed invasion. If such positive effects also apply to low input agricultural grasslands, the resource-use efficiency could be improved. To investigate whether other grassland species and diverse grassland mixtures could be more productive, a grassland on a shallow sandy soil in the south of the Netherlands was sown in April 2009 with seven non-leguminous grassland mixtures. Though some sown species vanished quickly, diverse mixtures proved less susceptible for invading species three years after sowing (p<0.05). Yields in 2010 and 2011 were 11% higher for mixtures with two functional groups of grassland species compared with mixtures with...

Organic dairy farmers in The Netherlands, supported by the Louis Bolk Institute, developed a calf rearing system in which newborn heifer calves suckle their mother or a nurse cow up to three months of age. Consumers played an important role. Their critical questions made farmers take the initiative to investigate and develop an alternative way (more animal friendly) to raise organic dairy calves. Increased animal welfare and health were the focus of system development, but the practical and economic feasibility of the rearing system also received attention. Farmers implementing a suckling system aim to raise well-developed dairy cows that fit easily into the dairy herd and are adapted to the existing farming conditions. Natural bonding between calves and... Tipo: Conference paper, poster, etc. Palavras-chave: Dairy cattle; Feeding and growth. Ano: 2009 URL: http://orgprints.org/17254/4/17254.pdf Suckling as an alternative rearing system for replacement calves on dairy farms Organic Eprints Langhout, Jos; Wagenaar, Jan-Paul. The aim is to develop an alternative calf rearing system for replacement calves that will improve animal welfare on dairy farms and meets the requirements of farmers in terms of practicality and cost. On the dairy farms that make use of a suckling system are calves suckled by their mother or a nurse cow, for a duration that ranges from three days up to three months. Compared to artificial calf rearing, suckling systems are beneficial to the welfare of calves. The calves will be nursed by their mother, suckled with milk, learn to eat roughage at a younger age, have social contact with other calves and cows and have space enough to exercise and play.
