dc.description.abstracteng | The prevention of animal health problems
is crucial in organic livestock farming: this may be achieved by
choosing appropriate animal housing conditions as well as suitable
breeds and, offering high quality feedstuffs, allowing grazing or
outdoor-running, and considering proper stocking densities. To
date, relatively little is known about the specific dairy health
situation under the conditions of organic husbandry and specific
preventive concepts are hardly known to most organic milk
producers. The objectives of the present thesis were, first, to
assess the status quo of the animal health situation in organic
dairy farming through a survey in a representative sample of farms;
secondly, to develop a concept for farm-individual herd health
plans; and, thirdly, to apply such health plans in the course of
intervention studies on organic dairy farms. Additionally, studies
of inter-observer agreement regarding locomotion scoring and a
survey, which evaluated the acceptance of herd health plans by the
farmers, were carried out. The thesis consists of an introduction
to the topic followed by five chapters and a concluding summary.
The first chapter contains results from an investigation which
analysed the status quo of the animal health situation of organic
dairy farming in Germany. On-farm surveys with regard to cow
health, medicine use and milk recording data in 50 (year 2002/
2003) and 43 (2004/ 2005) representative farms revealed that
production diseases such as clinical mastitis, lameness and
metabolic disorders seriously affect organic dairy farming.
Prevalences and incidences (e.g. mastitis) were similar in range to
those found in conventional dairy farming and specific concepts for
prevention were hardly known. A lameness intervention study in
organic dairy farming is in the focus of the second chapter. The
aim of this study was to develop and validate a preventive animal
health concept, taking lameness as an example, and to demonstrate
that it can successfully be implemented into practice.
Farm-individual catalogues of measures were developed in
cooperation with the farm manager and implemented on 21
intervention farms. The lameness situation was then recorded during
regular farm visits over a period of four years (2005 - 2009) and
compared with the situation on 19 control farms, where no measures
were in effect. Results showed that lameness prevalence was
significantly and consistently reduced on the intervention farms by
more than 50%. This was also the case, when the baseline situation
was considered in the statistical model. The prevalence of limb
injuries (here: swelling of the carpal joint) was also reduced by
introducing specific measures to improve cow comfort of the lying
surface. In our studies, animal related parameters were recorded
using subjective assessment protocols, e.g. locomotion scoring,
which can be easily applied on-farm and do not require technical
equipment. These assessments are suitable for on-farm surveys
provided that an acceptable level of inter-observer reliability can
be assured. In the third chapter we therefore evaluated the
training effect for an observer in using a five-point locomotion
scoring system. The agreement between an experienced and a na | de |
