Organic Livestock: Animal Health, Welfare and Husbandry Assessment of existing knowledge and production of an advisory resource compendium(OF0162)

1. A compendium of animal health and welfare information relevant to organic livestock production has been produced by the Organic Livestock Research Group (OLRG), Veterinary Epidemiology and Economics Research Unit (VEERU), Department of Agriculture, the University of Reading. The compendium is supported by full scientific abstracts taken from the CAB International information database. 2. The objective of the project was to: - Create a database and archive of information on animal health, welfare and husbandry relevant to livestock production under organic standards; - Assess the database and its relevance to organic livestock production; - Develop a series of compendia of advisory resource materials on CD-ROM and in printed format, in consultation with relevant sector bodies, the veterinary profession and organic livestock producers. 3. The compendium has been produced in a CD ROM format and is internet accessible (http://www.organic-vet.reading.ac.uk/). The compendium has been reviewed by specialist veterinarians, advisors and farmers. For copyright purposes, the internet accessible version has been produced without scientific abstracts 4. The aim of the compendia is to serve as a resource material for advisors, inspectors and veterinarians who work with organic or converting farmers in the UK. It is also envisaged that the compendia could be used as a training tool for advisors and veterinarians learning about the issues related to general and specific animal health and welfare aspects of organic livestock production. In addition, the material will provide a useful resource material for the sector bodies and policymakers in the development of organic livestock production standards and regulations. 5. Each compendium is divided into four sub-compendia: Cattle, Sheep, Pigs and Poultry. Each is further divided into two sections. An introductory section, Health and Welfare, outlines general health and welfare issues related to the specific organic production system. Emphasis is placed on the requirements of organic standards in the approach to health and welfare problems. A second section, accessible via the Disease Index, deals in detail with the specific conditions affecting the species in question. Each disease is indexed alphabetically, and by the veterinary and common terms normally applied. 6. The Disease Section describes a range of specific condition is divided further into sub-sections on causes, symptoms, treatment, control, prevention, welfare implications, good practice based on current knowledge and guidelines for the conversion period. The poultry compendium does not contain a sub-section on the conversion period as there is little technical information available to support this. 7. In total, the compendium covers 45 cattle, 44 sheep, 32 poultry and 27 pig diseases and conditions. 8. Each section is supported throughout by references to scientific literature and other publications. These references can be accessed directly from the text by using text links to scientific abstracts, scanned-in advisory materials and reference or reading lists. 9. The compendium has Help and Search facilities. 10. At the time of publication. the compendium contains over 1700 scientific references and more than 50 full advisory documents. It is intended that this particular feature of the compendia will prove useful when in-depth information is sought, or the compendia are used as a training tool. 11. It should be emphasised that the compendium is not intended as a diagnostic or self-help tool for animal health management on the farm. For this reason, diagnostics are not covered in any depth, and the treatment sections usually only suggest potential treatment categories and discuss the urgency and need for treatment from an animal welfare perspective. The authors wish it to be known that diagnosis should always be carried out by a veterinary surgeon, in response to problems seen on a farm. 12. The compendium have been reviewed by members of the advisory team at the Organic Advisory Service on Elm Farm Research Centre in Berkshire, by specialist veterinarians and by organic farmers. 13. In light of the rapid developments within organic farming and research, it is proposed that the information contained within the compendium will require frequent updating, probably on an annual basis. A proposal for the maintenance and expansion of the compendium has been included within the final proposal. The main component of this proposal is the development of a “stakeholder club” of interested parties, whose function would be to raise financial support, to supply technical information and to provide a practical link to the organic farming, advisory and administrative sectors

Implementation of farmer groups for animal health and welfare planning considering different contexts

This paper reflects some of the discussions that took place during the ANIPLAN workshop where participants discussed the special farming and farmer characteristics, needs and conditions in their own country in relation to farmer discussion groups, as well as more generic issues to consider when taking a farmer group approach to animal health and welfare planning. Farmer discussion groups are not unique, and there are examples of different approaches to, and aims of, farmer groups worldwide. Perhaps an important starting point when analysing the successes and characteristics of these groups is to consider their original purpose. The starting point of the discussion in the ANIPLAN project has been the so-called Danish Stable Schools (Vaarst et al., 2007; Vaarst et al. 2008; mentioned in Vaarst ibid.), as well as existing approaches within the other participating countries, such as the Dutch Caring Dairy groups (Smolders, ibid.). A major feature of the Danish Stable Schools has been the time limited intensive working towards a common goal based around equal participation within the group. This is quite a different approach to other examples, such as the so-called ‘erfa-groups’ in Denmark (‘erfa’ as an abbreviation of ‘erfaring’, which in Danish means ‘experience’) that have worked for decades on dissemination of new knowledge and ideas to and among farmers, focusing on separate themes at each meeting, such as approaches to parasite control, winter feeding strategies, or the use of body condition scores. Similar focused dissemination programmes exist in many countries. What characterises the ANIPLAN project is that the focus is on a rather more systematic animal health and welfare planning process which is meant to be continuous at the farm level

The ANIPLAN project: Reflections on the research approaches, methods and challenges

The objective of the ANIPLAN project is to ‘investigate active and well planned animal health and welfare promotion and disease prevention as a means of minimising medicine use in organic dairy herds’. The basic idea lying behind this objective is that the active development of plans at the farm level to improve herd health and welfare will enable individual farmers to practically achieve the organic principles with regard to the health and well-being of organically-farmed animals. To fulfil the objective, the project needs to be carried out in close collaboration with farmers and conducted in real farm situations. This means that the research is being carried out in an environment which is not under control the control of researchers. This, in turn means that there are inevitable methodological issues which will arise during the course of the study. This paper describes some of the issues arising during the first part of the study i.e the setting up of the project and the first year of data collection. One major challenge for the research team involved in this project is to identify research methods which can describe and document the planning process as well as the disease, production and medicine use on study farms. This documentation will enable the researchers as well as the end-users of the research to evaluate the approach and the effect of animal health and welfare planning on herds. This includes the process of animal health and welfare planning, which can be regarded as an iterative social and individual human development process. The transformative learning process (Vaarst, ibid.) leading to a change of perceptions and priorities of those involved should be expected before actual changes are implemented in the herds. Again, there are methodological issues to consider in this respect

Organic Farming in Cornwall: Results of the 2002 Farmer Survey

A detailed survey of organic farming in Cornwall was completed duing the period August 2002 to February 2003. One of the main objectives of the survey was to describe current practices and constraints to organic production so as to aid the Organic Studies Centre in developing a research and training strategy that meets the needs of Cornish organic farmers. all 130 registered producer members of the Soil Association Certification Ltd (SACert) and Organic Farmers anf Growers Ltd (OF&G) were contacted. Of these, 120 were farming and 119 were interviewed. Data collected through closed questioning reflected a wide range of land-use, enterprise, marketing, husbandry, management, certification, income and environmental issues. Comments from farmers, recorded through open-ended questioning, are quoted and para-phrased throughout the report. The survey has provided the first detailed description of organic production in Cornwall. These data will be used by the Organic Studies Centre at Duchy College to form the basis of a strategy for organic farming research and development relevant to Cornwall. The information gathered will also be used to inform other parties concerned with development of the organic sector in the UK generally, at the south west of England specifically. A second follow-up survey will be conducted during 2005. This survey would not have been possible without the considerable efforts of the data collectors and the goodwill, time and expertise ofthe participating farmers. These contributions are gratefully acknowledged

The productivity of organic dairy herds

This report was presented at the UK Organic Research 2002 Conference. Organically managed ruminant systems place particular emphasis on maximising production from forage. Therefore, it is important that efficiency measures take full account of forage inputs. The Livestock Production Efficiency Calculator (LPEC) calculates the total metabolisable energy (ME) required by livestock and estimates forage inputs as the difference between total requirement and that supplied by other measured feeds. Productivity is expressed in terms of output (£) minus other valued inputs (£) per unit of forage ME. Estimates of production parameters were used to produce productivity indices for thirteen organic dairy herds. The productivity of herds was compared, and sensitivity analyses were conducted to examine the potential impact of a number of economic and production scenario. The relationships between yield, fertility, culling and herd productivity were examined. The advantages of this productivity analysis of organic production systems is that full account is taken of the most important input i.e. grazed and conserved forage and that all of the determinants of productivity and their interactions are considered

Fertility and fertility management in thirteen well-established organic dairy herds in the UK

This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR). Milk production and breeding records from thirteen organic dairy herds were collected between January 1997 and December 1999. Mean lactation yields in the herds ranged from 5127 kg to 7031 kg. Whilst seasonality of calving varied widely between herds, a majority of them (6/13) were autumn calving. Mean calving to first service interval was 80 days (range 68 to 97), and mean calving interval was 385 days (range 370 to 413). The mean number of services per conception was 2.3 (range 1.6 to 3.1). Overall culling rates and culling rates for fertility related problems were at 15.8% and 5.4%, respectively. A preliminary study of selected breeding periods of cows that had a subsequent calving revealed no significant differences in calving interval between high or low yielding cows or between cows with different calving month or parit

A Dose of Reality: Overcoming Usability Challenges in VR Head-Mounted Displays

We identify usability challenges facing consumers adopting Virtual Reality (VR) head-mounted displays (HMDs) in a survey of 108 VR HMD users. Users reported significant issues in interacting with, and being aware of their real-world context when using a HMD. Building upon existing work on blending real and virtual environments, we performed three design studies to address these usability concerns. In a typing study, we show that augmenting VR with a view of reality significantly corrected the performance impairment of typing in VR. We then investigated how much reality should be incorporated and when, so as to preserve users’ sense of presence in VR. For interaction with objects and peripherals, we found that selectively presenting reality as users engaged with it was optimal in terms of performance and users’ sense of presence. Finally, we investigated how this selective, engagement-dependent approach could be applied in social environments, to support the user’s awareness of the proximity and presence of others

The mechanosensitive ion channel TRAAK is localized to the mammalian node of Ranvier.

TRAAK is a membrane tension-activated K+ channel that has been associated through behavioral studies to mechanical nociception. We used specific monoclonal antibodies in mice to show that TRAAK is localized exclusively to nodes of Ranvier, the action potential propagating elements of myelinated nerve fibers. Approximately 80 percent of myelinated nerve fibers throughout the central and peripheral nervous system contain TRAAK in what is likely an all-nodes or no-nodes per axon fashion. TRAAK is not observed at the axon initial segment where action potentials are first generated. We used polyclonal antibodies, the TRAAK inhibitor RU2 and node clamp amplifiers to demonstrate the presence and functional properties of TRAAK in rat nerve fibers. TRAAK contributes to the leak K+ current in mammalian nerve fiber conduction by hyperpolarizing the resting membrane potential, thereby increasing Na+ channel availability for action potential propagation. We speculate on why nodes of Ranvier contain a mechanosensitive K+ channel
