Abstract

Nowadays it‘s more and more important for food consumers, to consume food of high quality. At the same time the economic pressure on the food industry increases. A quality defect of produce can mean losses in processing. A substandard qualitiy of produce can negatively affect the economic situation of the producing farmers. To produce high quality milk, it’s necessary that the production and surveillance form part of a quality assurance system. This system works as an early warning system. Deficiencies in udder health and milk production can be detected early by regulary controlled so called Critical Control Points and Control Points and can so be remedied and prevented. The aim of this study was to find Control Points and Critical Control Points as parts of a quality assurance system (QAS) for the control areas of milk quality and udder health in Dairy herds. This quality assurance system was finally implemented in the Veterinary Herd Controlling System (VHC-System) as a part of the Integrated Veterinary Herd – Health Advisory System (IVAS). Based on the research of national and international literature, a quantity of direct and indirect Control Points and Critical Control Points was collected. To be put in the VHC-system the Control Points have to meet certain demands. If they don’t meet these demands, further investigation or some action of improvement has to occur. Critical Control Points are examinations, which are indispensable for the maintenance of udder health. They are placed on level of the Status quo-assessment. Their controlling has to be cost-effective and practical for monitoring routine. Control Points are continuative examinations or actions, which are performed if Critical Control Points oder superior Control Points exceed their thresholds. So called “Direct“ Control Points are referring directly to animal health or performance. “Indirect“ Control Points serve the controlling of animal environment. For each Control Area an intensity pyramide was constructed. So the activities can be fit in the VHC-System following Status quo assessment, aimes and situation of each dairy farm. The found Control Points and their indicators were implemented in a flow chart to be used by the veterinarian as a tool for the Status quo assessment and the herd health advisory in the control areas milk quality and udder health. Due to the dynamic it is possible to adapt the system to the needs and possibilities of each dairy farm. The implementation of the QAS in the VHC-System of the Integrated Veterinary Herd – Health Advisory System enables to control, discuss and if necessary to improve the control areas udder health and milk quality. This effects an improvement of udder health and guarantees the fulfillment of the requirements to milk quality on the part of the consumers, the law and dairy industry.
