Developing a Mastitis Pattern Analysis Tool
A mastitis pattern analysis tool was designed and tested. The tool ensures that data are analysed in a structured, consistent and accurate way, based on herd somatic cell count as well as clinical mastitis records. It produces a mastitis pattern report that allows farmers and vets to assess and prioritise the key management areas and potentially detect emerging problems.
• If use of the Mastitis Pattern Analysis Tool facilitates a reduction in clinical and subclinical mastitis of only 3% per year for a dairy farm with 150 cows and average levels of clinical and sub-clinical mastitis, this would result in a net financial return of £900 per year or £4,500 in 5 years.
• Reduced culling rates and waste milk as a result of reducing mastitis will result in environmental benefits via reduced greenhouse gas emissions.
• Reducing mastitis levels will also improve animal welfare, and enhance industry image.
About this project
In recent years, the AHDB Dairy Mastitis Control Plan (DMCP) has had a significant positive impact on-farm, with an estimated >15% of GB cows receiving mastitis control through the plan. Despite this excellent performance, the first stage of the plan, making a ‘herd diagnosis’ is particularly difficult. This is an essential first step because control measures later identified are dependent upon a correct diagnosis at this point.
- To create a fully automated method of making a herd mastitis diagnosis so that mastitis issues can be identified, quantified and prioritised to enable effective targeting of control measures
- To evaluate the new automated method of herd mastitis diagnosis by assessing it against 50 dairy herds in which a known herd diagnosis has been made by an experienced Dairy Mastitis Control Plan Deliverer
