Advantages and Disadvantages of Rotary Milking Parlours

In the modern dairy industry, farmers have various options when it comes to milking systems. One such system is the rotary milking parlour, which offers several advantages and disadvantages for dairy operations. Understanding the pros and cons of this milking system can help farmers make informed decisions about their herd management practices.

In this blog, we will explore the advantages and disadvantages of rotary milking parlours and discuss important factors to consider when choosing a milking system.

What is a Rotary Milking Parlour?

A rotary milking parlour is a type of milking system designed to efficiently and effectively milk large herds of cows. It consists of a circular platform that rotates slowly, allowing multiple cows to be milked simultaneously. As the platform rotates, cows are brought into position for milking, and the milking process is automated.

How Do Rotary Milking Parlours Work?

In a rotary milking parlour, cows enter the milking platform and are guided into individual milking stalls. The platform then rotates, bringing each cow into position for milking. As the cow is milked, the milking unit is automatically attached to the udder, and milk flows into a collection system. Once milking is complete, the unit automatically detaches, and the cow exits the milking platform.

Advantages of Rotary Milking Parlours

Increased Milking Efficiency

One of the primary advantages of rotary milking parlours is the increased milking efficiency they offer. The rotating platform allows for a continuous milking process, minimising the time spent on cow positioning and maximising the number of cows milked per hour. This efficiency can be especially beneficial for large-scale dairy operations with a high number of cows to milk.

Labour Savings

Rotary milking parlours can lead to significant labour savings compared to traditional milking methods. The automated milking process reduces the need for manual labour during milking, freeing up farm personnel to focus on other essential tasks. With the ability to milk multiple cows simultaneously, fewer operators are required to complete the milking process efficiently.

Improved Cow Comfort

Cows’ comfort and well-being are crucial factors in dairy farming. Rotary milking parlours are designed with cow comfort in mind. The spacious milking stalls provide ample room for cows to stand and move comfortably during the milking process. The automated system also ensures that cows are not subjected to excessive waiting times or discomfort.

Enhanced Milk Quality

The design of rotary milking parlours promotes better milk quality. The automated milking units are equipped with advanced technology, ensuring consistent and gentle milking practices. Proper udder preparation, teat cleaning, and milking machine attachment can help minimise the risk of mastitis and other milk quality issues. As a result, rotary milking parlours can contribute to higher milk quality standards.

Disadvantages of Rotary Milking Parlours

High Initial Investment

One significant disadvantage of rotary milking parlours is the high initial investment required. The construction of a rotary parlour and installation of the necessary equipment can be expensive, making it less feasible for smaller dairy operations with limited budgets. However, for larger farms with a sizable herd, the long-term benefits may outweigh the initial costs.

Limited Space Requirements

Rotary milking parlours require a significant amount of space compared to other milking systems. The circular layout of the platform and the need for supporting infrastructure mean that farms must have adequate land available to accommodate the parlour. Space limitations can be a challenge for farms located in areas with restricted land availability.

Increased Maintenance and Operating Costs

Operating a rotary milking parlour involves ongoing maintenance and higher operating costs compared to traditional milking systems. The complex machinery and automation systems require regular maintenance and occasional repairs. Additionally, the electrical and mechanical components can lead to increased utility expenses. Farmers considering a rotary milking parlour must factor in these ongoing costs.

Reduced Flexibility in Milking Schedule

While rotary milking parlours offer increased milking efficiency, they may limit flexibility in milking schedules. The rotating platform operates at a fixed speed, meaning that all cows must be milked within a certain timeframe. This can be challenging for farms that require more flexibility in their milking routines, such as those with cows in different lactation stages or herds with varying milking frequencies.

Factors to Consider When Choosing a Milking System

When deciding on a milking system for a dairy farm, several factors should be taken into account:

Farm Size and Herd Management

The size of the farm and the number of cows in the herd are essential considerations. Larger farms with a high number of cows can benefit from the efficiency of rotary milking parlours. Smaller farms may find traditional milking methods more suitable.

Budget and Financial Considerations

Farmers must carefully evaluate their budget and financial resources before investing in a rotary milking parlour. While the system offers advantages, the high initial investment and ongoing maintenance costs must be considered.

Cow Health and Welfare

The comfort and well-being of the cows should be a priority. Dairy farmers should assess how a milking system, such as a rotary parlour, impacts cow health, stress levels, and overall welfare.

Future Expansion and Adaptability

Farmers should consider their long-term goals and plans for expansion. Will the chosen milking system be able to accommodate potential increases in herd size or changes in milking practices in the future?

Rotary milking parlours offer several advantages and disadvantages for dairy farmers to consider. The increased milking efficiency, labour savings, improved cow comfort, and enhanced milk quality make them an attractive option for large-scale operations.

However, the high initial investment, space requirements, maintenance costs, and reduced milking schedule flexibility are important considerations.

By carefully evaluating the specific needs and goals of their dairy operation, farmers can make informed decisions about which milking system best suits their requirements.


  1. Are rotary milking parlours suitable for small farms? Rotary milking parlours are more commonly found in larger farms due to their high initial investment and space requirements. Smaller farms may find traditional milking methods to be more suitable and cost-effective.
  2. What is the average milking time in a rotary milking parlour? The average milking time in a rotary milking parlour can vary depending on factors such as the number of cows in the herd and the speed of rotation. However, on average, it takes around 7-10 minutes for a cow to be milked in a properly functioning rotary milking parlour.
  3. Can rotary milking parlours accommodate different cow sizes? Rotary milking parlours are designed to accommodate a range of cow sizes. The milking stalls are adjustable to ensure that cows of various sizes can be comfortably milked within the system.
  4. How often do rotary milking parlours require maintenance? Rotary milking parlours require regular maintenance to ensure optimal performance. Routine maintenance tasks, such as cleaning and lubrication, should be carried out daily. Additionally, periodic inspections and servicing by qualified technicians such as those at Electromech Agri are necessary to address any potential issues.
  5. Are there any alternative milking systems to consider? Yes, apart from rotary milking parlours, there are other milking systems available, such as  automated robotic milking, and parallel milking parlours. Each system has its own advantages and disadvantages, and farmers should evaluate them based on their specific needs and circumstances.
