AMS på bedriftsniveau
01/01/2002 - 31/12/2006The prupose is the generate a decision framework for evaluatin the overall effects of impelmenting an AMS system on a dairy farm. Further it is calyfied how deciion support can be improved regarding animal health, welfare and producticity
CEPROS II - Decision support systems pig production
01/01/2003 - 31/12/2006It is the purpose of this project to develop a decision support system for the economics of health management in a pig herd. The system will focus on the interaction among the most important disease complexes in growing pigs and their economic consequences to support health management decisions at herd level.
Kvægproduktion 2010 - DJF
01/01/2003 - 31/12/2007To develop decision support tools for different types of managers
To characterise different dairy herds
To develop strategies for promoting animal health and welfare in dairy cattle herds.
OM-AMS-HOF
01/01/2004 - 31/12/2006The purpose of the project is to develop a monitoring and handling programme based on the HACCP concept and targeted at dairy producers in their first years after introduction of AMS. The project is divided into three phases:
Phase 1: Development of a prototype monitoring system
Phase 2: Testing of the system in AMS dairy herds
Phase 3: Documentation of the system
On-farm animal welfare assessment for farmers and authorities
01/01/2009 - 31/12/2012The purpose of the project is to develop a method for identifying livestock herds which is likely to have severe animal welfare problems and further clarify how a distinction between an acceptable and an unacceptable level of animal welfare problems can be made. The project will search for ways for motivating livestock farmers for cooperating with the authorities aiming at improving animal welfare in their herd. The project will contribute to an elevation of the lower level of animal welfare in Danish livestock production, which will satisfy an important expectation among consumers and strenthen the livestock industry.
Overskudsmælk til kalve
01/01/2006 - 31/12/2007The purpose of the project is to ímprove the health status of the calf in danish dairy production theough development of safe and operational routines for application of waste milk
Prevention and handling of weak sows
01/01/2007 - 01/01/2009The objective of the project is to conduct research targeting an improvement og animal welfare in Danish sow herds through improved prevention and handling og weak sows in systems with loose housed pregnant sows. When the results are implemented we expect that the welfare of the sows are improved in a manner, which will improve farm economy as well. The objective will be achieved through the following goals:
1. Identification of sows with an elevated risk for culling/euthanasia (wakk sows) in systes with loose housed preghgnant sowsand further to obtain increased knowledhge on how the stockman identifies and handle sows with difficulties in these systems
2. To indentify risk factors and to estimate efffetcs of prevalence of weak sows
3. To improve an existing replacement model for sows targeting handling of weak sows
Prevention om lameness in dairy cows through improved housing and management
01/01/2007 - 31/12/2009The obejctive of the project is to evaluate the effect of improved housing and management on the incidence of digital dermititis and laminitis. Acknowledging the complex relationship between housing and management the milk producer will be provided with systems orientated and opretational management strategies, which wil efficiently prevent digital dermititis and laminitis
In the proejct the two main quastions rare:
What is the eeft of diffferent floor and floor hygiene?
What is the relation between housing and hygiene and between hygiene and hoof health in Danish loose housing dairy cattle systems and what is the importance of time budget in relation to hoof health?
QLIF-Quality Low Input Food
01/03/2004 - 28/02/2006(i) To quantify the pathogen transfer risk associated with pigs produced in different conventional (in door and outdoor rearing) and organic production systems taking transport stress and management practices into account.
(ii) To assess whether the use of ELISA tests to identify animals that have been exposed to a pathogen, may provide a false picture of the situation, by overestimating the safety risk from early infections, where the immune system may be able to completely eliminate the pathogens.

Automatic hoof care in dairy cows - development and evaluation
01/08/2007 - 31/12/2010The objective is to develop and evaluate an automatic system for hoof care in dairy cows. The project is expected to increase hoof health among dairy cows. This in turn will have positive effects on animal welfare and farm economics. At the same time, an automatic system will mean less manual work for the dairy farmer.
Bull calf welfare assessment (BCW) - Decision support and documentation
01/01/2006 - 31/12/2008Bull calf producers are challenged with animal welfare problems such as respiratory disease, liver abscess, laminitis, scab and mortality. Commercial bull calf production in Denmark is often conducted in ‘concept systems’ specifying housing conditions and management procedures for animal welfare reasons. Since this aspect plays a major role in marketing the meat these production concepts are vulnerable to public critique on animal welfare. The project aims at developing a management system for improvement and documentation of bull calf welfare at herd level. The project develops a welfare monitoring protocol based on external welfare assessment of animal clinical health and behaviour, housing system and management, as well as data of medical treatments, meat inspection data as well as the mortality rate. The protocol is implemented in 16 specified bull calf herds during 2007-2008. A running feed-back of welfare assessment results to the individual farmer forms the basis of an evaluation procedure of the validity of the management system for decision support and documentation. Further evaluation is focused at estimating the possible correlation between welfare measures and production measures as growth, classification, medicine usage etc.. Finally, the project introduces the management system to the Danish advisory service.
Dairy herds, decision support for herd health consultancy
01/10/2006 - 30/09/2009The purpose of the project is through a new cooperation among veterinarians, researches and Danish Cattle, to develop a decision support system for economic analyses of improved heatlh i dairy herds. I modern dairy herd new management routines are frequently implemented in the individual herd to take advantage of new opportunities for health monitoring and for prevention of those health problems that are present in the herd. The dairy farmer wants to know the health related as well as the economic related consequences of the alternative opportunities before he decide on which of them to implement. The veterinarian, on the other side, has a need to provide a prognosis for the expected use of medication until his next regular visit in the herd. Prototypes are developed by researchers and professionals in software development and the tools are evaluated in practise by veterinarians in routinely herd health consultancy. Based on these results a web-based tool is developed. It is expected that the tool has national and international potential to promote animal welfare and economy in dairy herds.
