Grazing and Robots: Finding the Perfect Balance at Grass

For many dairy farmers, the idea of combining grazing with robotic milking can seem like a challenge. However, for one family farm milking 58 Holstein, Ayrshire and Brown Swiss cross cows, the move has delivered greater flexibility, improved herd performance and a simpler way of managing cows. 

The decision to invest in robotic milking was largely driven by labour. With David becoming the only full-time member of staff as his parents approached semi-retirement, finding a system that could reduce labour pressure while maintaining production became increasingly important.

Like many farmers considering the transition, his biggest concern was whether the cows would adapt to the robot. In reality, the herd settled well, and the system has proven particularly beneficial for youngstock, with heifers integrating easily and finding their place within the herd.

Looking back, David says he wishes he had known more about A/B/C grazing before starting. Since installation, the system has continued to evolve. Cow genetics and milk production have improved, a Lely Discovery Scraper has been installed, and future plans include introducing a permanent footbath system. The farm has also moved away from milk recording, instead relying on the wealth of information available through Horizon management software.

Today, grazing is managed using an A/B/C grazing system. Fresh paddocks are made available throughout the day, with cows moving to Graze A at 1:30am, Graze B at 10am and Graze C at 6:30pm. In the evening, cows also receive an indoor buffer feed consisting of baled silage, potatoes and a blend ration. Grass utilisation is maximised through strip grazing with a backing fence, with paddock allocations typically ranging from three to four yards depending on the field.

The combination of grazing and robotic milking has not only maintained production but helped drive it forward. The herd is currently averaging 37.6 litres per cow, with 2.8 milkings per day and just 1.6 refusals. These figures have exceeded expectations, having previously averaged around 30 litres through the parlour.

One of the biggest advantages has been the ability to identify health issues earlier. By finding and using the reports that suit the farm’s management style, Horizon provides valuable insights that allow problems to be spotted and addressed more quickly. Overall, David describes the herd as easier to manage and believes the system gives him greater control than before.

For farmers considering robots while still wanting to graze cows, his advice is straightforward: start with high-quality, fresh grass, ensure the correct infrastructure is in place before installation, understand how your grazing layout will work, and, most importantly, visit farms already successfully grazing with robots.

As this farm demonstrates, robotic milking and grazing can work hand in hand. With careful planning and the right infrastructure, farmers can continue to make the most of home-grown forage while benefiting from the flexibility, data and efficiency that automation provides.
