Adapting to the changing world of genetics in dairy farming: the search for the ‘Invisible Cow’

Andrew Thompson, Consultant, Preston

Introduction

The dairy farming industry is undergoing a significant transformation, largely driven by advances in genetic research and breeding technologies. As farmers seek to optimise production, improve herd health, and increase sustainability, they are confronted with a new challenge: navigating the evolving genetics landscape.

The search for the ‘invisible cow’ – a term that represents the ideal dairy cow of the future – has intensified as industry stakeholders recognise the crucial role genetics plays in shaping the future of dairy production. This paper explores the changing genetics industry, the impact of these changes on dairy farmers, and how they will need to adapt to remain competitive and sustainable.

The Genetics Revolution in Dairy Farming

Over the last few decades, the genetics industry has revolutionised dairy farming practices, offering farmers unprecedented opportunities to improve herd performance. Conception rates, for instance, have improved significantly, with an average conception rate now standing at 39% (Hanks et al. 2024, University of Reading), a remarkable 7-point increase over the past 14 years. This surge in fertility is attributed to a combination of factors: more intense breeding strategies, healthier herds, better farm environments, and advances in semen technology. These developments have led to faster genetic progress, higher yields, and a more efficient farming process. However, while these advancements have brought about a more productive industry, they have also created new challenges, particularly for genetics businesses. The more efficient breeding process has reduced the overall number of straws of semen needed to be sold to maintain herd size, thus diminishing the revenue for genetics companies.

This 22% reduction in semen sales, through fertility alone, has resulted in a significant income loss for the genetics industry, with estimates showing that the reduction in income from genetics businesses could be in the tens of millions of pounds globally, for each of those who market on a global basis.

While farmers benefit from improved dairy cow performance, greater income from beef calves, and improved animal well-being, genetics businesses are seeing shrinking margins and a shrinking market. This economic discrepancy signals a major shift in the market, with genetics businesses facing increased consolidation as they strive to remain profitable.

The Role of Genetics Businesses in the Changing Landscape

The changing dynamics of the dairy industry have prompted genetics businesses to rethink their strategies. As the demand for more efficient dairy herds continues to grow, genetic companies are faced with the difficult task of staying relevant in an increasingly competitive marketplace. To achieve this, they are focusing on cost savings, particularly in field operations, as well as pushing for greater investment in research and development (R&D) to continue advancing genetic progress. However, these innovations come at a steep cost.

For global genetics companies, market penetration and strategic alignment with international breeding standards are critical for survival. Companies must decide which ‘race’ they want to run – whether to prioritise genetic progress in high-volume markets like the US or to target the rapidly evolving genetic needs of diverse markets across the world.

Given the global scale of the market, estimated at 200-250 million doses annually, genetics companies are under immense pressure to develop products that are not only efficient but also adaptable to various farming systems and markets.

Furthermore, genetics companies are increasingly engaging in partnerships with farmers through contractual agreements. These partnerships, often focused on creating ‘nucleus herds,’ involve strict terms to safeguard the value of genetic material. These arrangements help to mitigate the risk of ‘genetic leakage,’ which can result in significant financial losses for genetics companies. With sires like ‘Shottle’ in the past and ‘Captain’ more recently, subsequently influencing at least 4-5 generations of animals and beyond, it’s conceivable that easily tens and perhaps even hundreds of millions of pounds of the value of any of these genetic businesses, could be wiped out with such leakage.

As a result, it is critical for farmers to understand the nuances of these contracts and their implications for herd management, as failure to comply with contractual terms could result in legal action and financial penalties.

Adapting to a New Era of Genetic Breeding

For dairy farmers, adapting to the changing genetics landscape involves embracing a combination of traditional breeding methods and new technologies. The integration of genomic testing, the use of sexed semen, and the development of specialised beef genetics are becoming increasingly essential for maintaining profitability and meeting consumer demands. Indeed, more beef today in the UK is now supplied from the dairy herd as crossbred animals, rather than traditional suckler style, pure bred animals.

Genomic testing has become a crucial tool for selecting the right cows to breed, helping farmers make more informed decisions about which animals to include in their breeding programs. Ultimately selection accuracy has been revolutionised through this process, all helping to contribute to the rapid genetic progress being made in the UK dairy herd. With genomic testing allowing for the identification of desirable traits early in an animal’s life, farmers are able to make better breeding choices that align with both economic and sustainability goals. Farmers who embrace genomic testing will be better positioned to improve herd health, reduce disease susceptibility, and increase overall milk production efficiency.

PLI ultimately embraces many of these traits and helps to shape why the UK dairy herd has remained relatively stable in population. Although profitability is never enough, when compared to other areas of the world, UK dairy farms perform competitively on a pence per litre cost of production.

Sexed semen has also played a transformative role in dairy breeding. By ensuring a higher proportion of female calves, farmers can increase their milk production potential while simultaneously reducing the number of male dairy calves, which we know had become a low value by-product of the breeding process. Similarly, the integration of beef genetics into dairy herds is helping farmers tap into new revenue streams. Beef calves, produced from dairy cows, offer a valuable market opportunity that helps to offset the costs of dairy farming and improve overall farm profitability.

As genetic advancements continue, it is likely that we will see even more specialised breeding programs designed to meet specific production targets. This includes the development of cows with optimised health profiles, higher feed efficiency, and reduced environmental footprints. These cows, often referred to as ‘invisible cows’ in the industry, are those that exhibit superior traits without necessarily being visible to the naked eye. These advancements hold the promise of creating more resilient, efficient, and sustainable dairy systems.

The Economic and Environmental Impact

One of the most significant challenges for the genetics industry is the cost-effectiveness of breeding programs. Ultimately many genetics businesses all around the world can find themselves investing close to £100,000 per bull in their own program before production costs, before considering spending a million pounds for a free agent top 10 bull in the world. Contrast this against the average farmer spending 1-2% (0.4-0.8ppl) of the cost of production on their genetics.

On the environmental front, genetic improvements hold great promise for reducing the carbon footprint of dairy farming. More efficient cows that require less feed to produce the same amount of milk can help reduce methane emissions and lower the overall environmental impact of dairy operations. As sustainability becomes a key focus for the agricultural sector, dairy farmers will need to prioritise genetic programs that align with both environmental goals and economic viability.

Conclusion

The dairy industry is entering a new era, one that demands increased attention to genetic strategies. The advancements in genetic testing, breeding technologies, and the integration of sexed and beef genetics have transformed how dairy farms operate. To remain competitive, farmers must adapt by staying informed about the latest scientific developments, understanding the financial implications of their breeding decisions, and forge strategic partnerships with genetics companies.

As the agricultural supply industry continues to consolidate, dairy producers need to pick their partners of choice, in the same way they pick their customers of choice of whom they sell their milk and livestock to. This isn’t just about purchase price but about delivering consistent value for money and the correct genetics for the long term vision of their dairy farm, with clarity around the terms of how they can market future genetics.

As genetic technologies continue to evolve, dairy farmers will need to embrace new tools and practices to optimise their herds and ensure long-term sustainability. While the search for the ‘invisible cow’ may seem abstract, the reality is that the cows of the future will be shaped by science, technology, and careful decision-making. Those who can successfully navigate this rapidly changing genetics landscape will be best positioned to thrive in the years to come.
