Yearly Guide & Report


Milking your cows by hand is a tiring and tedious task that most farmers don’t enjoy. Machine milking in dairy cows is the recommended choice since it allows you to be more productive and to meet the latest hygiene standards. Not to mention that it is much more comfortable for the cow when compared to manual milking.

With that said, it is not always easy to find the right product for the job, especially if this is your first time purchasing a milking machine. To make things easier for you, we have compiled a buyer’s guide that will go through the most important factors you ought to consider before you spend your hard-earned money.



Types available

There are four main types of milking machines currently available on the market: electric, battery, gas, and manual. Electric machines are perfect for small to medium-sized farms that have a handful of livestock. The reason for this is because electric units offer a great balance between power and cost, especially when compared to the other three types available.

The main disadvantage with this option is that you are limited by the length of the cable and the requirement of an outlet. You may use a generator to power an electric milker, but unless you already own one, getting one specifically for your milking machine is not cost-effective.

Models that are powered by a battery have the benefit of portability and that makes them perfect for small farms with few cows, especially if they are free-range. What’s more, this is also a cheap option which makes it perfect for small farmers that have a small budget to spare.

The big downside is that they cannot milk many animals because not only are they less efficient, but the battery won’t last for a lot of time. If you do get a unit that is powered by a battery, we recommend you go for a model that features rechargeable and replaceable batteries.

Gas milking machines are the most powerful of the four, but also the most expensive. A milker powered by gas requires gasoline as the fuel source which is much more expensive than electricity or even batteries. To add to that, most gas-powered models use a 4-stroke engine which means that maintenance can be a slog.

If you have a large farm with lots of cows to milk and you can’t afford to waste any time, getting a gas-powered milking machine is a good choice.

Finally, manual milkers do not require electricity, batteries, or gas and instead use the force of your hands to create a vacuum. They have a small pump that you need to press, and while they are great for people that only have a few cows, they are not recommended for seniors since the hand pump requires quite a bit of force.


Size and other specifications

The size of the equipment and its specifications can differ depending on your milking needs. There’s also the fact that products are updated on almost a daily basis which allows manufacturers to cater to all the needs of the farmer.

The size of the milk bucket is important and you should get the one that will allow you to make as fewer trips to empty it as possible.

Other key factors that you ought to consider include the number of livestock that you need to milk, the desired production quantity, frequency, and the speed of the product. For example, some machines that are designed specifically for milking cows have two pulsation rates, one for the rear teats and one for the forequarter.

That is because the rear teats are generally larger and that makes them require more time to eject the milk. Having two rates for milking can improve the efficiency of the machine as well as the health of the animal.

Some modern milking machines are fully automated which can make the job of the farmer that much easier since they clean themselves automatically and come with additional emergency options. They feature milk-flow sensors that determine when the machine must be removed from the udder.

As is expected, these options are much more expensive but their price is easy to justify if you own a large farm.


Pulsation is important

Milking machines can’t leave the vacuum on for extended periods since that could lead to stressing the teat and possibly causing serious injury to it. The pulsation of the milking machine will ensure that the blood continues to circulate to maintain the teat end healthy.

Most options on the market have a pulsator ratio between 50/50 and 70/30. The first number represents the amount of time that the pulsator will draw milk while the second one refers to how many times the atmospheric pressure will massage the udders.

You can vary these ratios to suit your livestock, but the preferred ratio for optimal operation is of 60/40. It is not recommended to go beyond 70/30 since those ratios could cause injury to the animal. You can test the comfort level that the pulsator offers by putting your finger into the cup for 20 seconds.

The effect that your finger feels is exactly what the cow will feel as well, and if it is uncomfortable for you, you should adjust it accordingly.




The material used for the cups is very important since the skin of cows can be just as sensitive as that of humans and you don’t want to use materials that could irritate or damage the skin. The cups need to be hypoallergenic which is why it is recommended to use non-reactive materials such as silicone. Avoid using rubber or latex.

An allergic reaction to a certain material will make the teats begin to swell with hives which will eventually lead to the infection of the milk gland which will start to secrete pus into the milk.

For the rest of the machine, you should use materials that are durable and resistant to corrosion and rust. This is the reason why stainless steel is the most popular and efficient material that most manufacturers use nowadays for the milker’s body.




Frequently asked questions about milking machines for cows


Q: How to get milk from cow with machine?

To milk a cow using a machine you start by cleaning the teats using an iodine and water solution so that dirt and other external contaminants don’t get into the milk. A milking machine is equipped with four cups and each one will fit over the four teats of the cow.

The motor of the machine will create a vacuum that will pump the milk out of the udders and into the milk bucket or container. The way the cups work is very similar to the way that a calf sucks milk and it does not hurt the cow nor make it feel uncomfortable.   


Q: How does a cow milking machine work?

While a milking machine may look complex at first, the principle on which it operates is actually quite straightforward. Basically, the machine pulls a vacuum on the teats of the cow and that causes the milk to flow. The action is similar to the sucking mechanism that a calf would use to nurse which makes it less uncomfortable for the cow than milking by hand.

The milk is then removed from the udder and transported to a sanitary storage vessel. When the cow’s udder empties, the milking machine will automatically shut off, while less expensive models will need to be powered down manually by the farmer.



Q: How to build a cow milking machine?

A cow milking machine is a complex device that utilizes a precise vacuum system and pulsations to provide the animal with a comfortable experience. While it is not beyond the realm of possibility that you could build one from scratch if you have the proper knowledge, it is best to put your trust in a product that was heavily tested to ensure safety and reliability.

If you are concerned that the price for a quality milking machine is too high, we found numerous cheap alternatives in our list of top-rated products that we are certain will satisfy your needs.


Q: Do milking machines hurt cows?

The short answer is no. A milking machine operates by employing a suction that is not constant, more like waves, and that allows it to simulate the non-continuous action of a calf sucking. Cows are very familiar with this feeling and that makes them feel comfortable while they’re being milked.

To add to that, the suction of a calf is much more vigorous than that of a milking machine. Using a milking machine is profitable precisely because its impact on the comfort of the cow is almost nonexistent. Compared to milking by hand, using a machine is a safer and more comfortable choice for cows.


Q: How much does a cow milking machine cost?

The answer to this question depends greatly on what type of cow milking machine you want to get. Battery-powered and manual milking machines can be found for under $100. Conversely, an electric machine can end up costing you between $1000 and $2000.

If you do want to get a machine that includes all the latest technology, you must be prepared to pay even more. There are many factors that can influence the cost of the product, and you should always focus on the features you need.

Once you’ve found the products that include the features you want, you can use the cow milking machine price as the deciding factor.


Prevention of mastitis in cows

Mastitis is one of the most devastating diseases that dairy farms can encounter. This potentially fatal mammary gland infection is generally caused by bacteria introduced either during the milking process or from environmental contact.

To ensure that you won’t have to deal with this nasty disease, we have prepared a comprehensive guide that will show you some of the steps you can take to protect your livestock.



Environment and nutrition

It’s important to keep the environment that your animals live in dry and comfortable. The stalls and the lounging areas will need to be maintained on a regular basis and provided with clean and dry bedding since cows that have dirty udders are much more susceptible to develop mastitis.

If the environment is not clean enough some animals will choose not to rest in the lounging area or in their stalls. Similarly, if you do find that your livestock is dirty, especially in the areas that rest upon the bedding such as under the stomach, and on their rear quarters, this is a very serious sign that you need to provide a cleaner environment.

For dry cows that are housed on a pasture, you will need to make sure that they have enough shade.

One other way to prevent mastitis in cows is to add the suggested amount and types of vitamins and minerals to your livestock’s feed so that you can offer a well-deserved boost to their immune system. A healthy and powerful immune system is essential in helping the body fight off mastitis.

A strong immune system will also require the right amounts of protein and energy, so make sure that your cows get the right amount of food.


Prevent metabolic disorders and vaccination

Many metabolic disorders such as ketosis can arise when the cow goes into a negative energy balance, namely when it does not eat enough feed to meet the needs of its body. During this time, it is critical to keep the fresh cows that are still in the four weeks period after calving eating since their energy needs are very high.

However, make sure that you don’t overfeed dry cows that are preparing for the next lactation.

Vaccination is also important and establishing a clear vaccination protocol for both dry and fresh cows can reduce mastitis in your herd considerably. To find the best vaccination schedule for both the farm and yourself, you should speak with your veterinarian and he or she will give you all the information that you need.


Proper milking

Make sure that the cattle are milked in a relaxed and stress-free environment since anxious or excited cows will not be able to relax and let their milk down. Similarly, you will need to check for mastitis every milking by using a mastitis strip or cup.

You’ll also need to establish a routine for periodic maintenance of your milking equipment since cattle are very sensitive to improperly working machines. A periodic maintenance routine will make it much easier for you to identify potential problems before they cause the milking machines to stop working or, even worse, hurt the animal.
