Genomic testing is revolutionizing the UK dairy industry, with significant improvements in herd health, productivity, and profitability. In 2024, over 112,000 cows underwent DNA analysis, leading to enhanced genetic selection and long-term sustainability.
The UK dairy industry is experiencing a transformative shift as genomic testing gains widespread adoption, with a record-breaking 112,507 cows undergoing DNA analysis in 2024. This marks a 19% increase compared to the previous year. The initiative, backed by the Agriculture and Horticulture Development Board (AHDB), is helping farmers assess the genetic potential of youngstock with exceptional precision, offering a significant step toward enhancing herd quality and long-term sustainability.
Genomic testing provides a detailed understanding of an animal’s genetic traits, enabling farmers to make informed decisions about which cows to breed. The practice is not only improving herd health and productivity but also delivering substantial economic benefits. According to AHDB data, farms that integrate genomic selection into their breeding programs experience higher productivity and profitability. On average, herds fully engaged in genomic testing have a lifetime profitability index (PLI) of $573 per animal, compared to $319 for farms that test only a portion of their calves.
The potential of genomic testing extends beyond financial gains. Experts highlight how the technology allows for a high level of precision, even identifying superior traits among non-identical twins in a herd. This accuracy enables farmers to enhance herd genetics gradually, leading to improved productivity, better health, and more profitable operations.
The increased adoption of genomic testing aligns with the UK dairy sector’s commitment to long-term sustainability. Farmer contributions to AHDB support this cutting-edge genetic research, which continues to strengthen the dairy industry’s position in both domestic and international markets. By leveraging genomic insights, the UK dairy industry is poised for continued growth, bolstering its competitiveness while improving environmental sustainability.
