The ability of milk to coagulate is crucial for cheese production. We have previously shown that 31% of milk from SR cows has problem to coagulate: 13% is poorly coagulating and as much as 18% is non-coagulating, which are alarming high figures. The problem with non-coagulating milk at national level corresponds to an amount of milk that has an economical value of 600 million SEK per year. The aim of the project is to identify markers and candidate mutations for non-coagulating milk in order to select against this undesirable property. Establishing the foundation for a breeding program to reduce the occurrence of non-coagulating milk will strengthen the competitiveness of the red breed and provide multifunctional milk suited for all dairy products. This will contribute to an increased growth and more profitable and sustainable production for the Swedish agricultural and dairy industries and stakeholders.
