A Day in the life

A Day in the Life of a Canadian Dairy Cow

It only takes a few minutes to milk a cow – so how do they spend the rest of their day? The answer involves a lot of chewing – and resting, and even a bit of socializing. How much time for each? it may depend on her personality! Read on to find out more about a typical day in the life of a Canadian dairy cow.

A Day in the life

Milking : Less than 1 hour

Using modern milking systems, it takes about 5-10 minutes to milk a cow. And cows are typically milked twice a day – once in the early morning, and again about 12 hours later. Some cows prefer to be milked more often when given the choice in a robotic setting. Milking a cow the old-fashioned way – by hand – would have taken a bit longer, about 20-30 minutes.

It also takes a few minutes to prepare a cow for milking, as every cow is individually cleaned and inspected, every time. And depending on the farm's setup, cows may have to wait their turn to be milked. On farms with robotic milking systems, cows can self-serve, meaning they can get milked whenever they want. Farms with milking parlours allow for many cows to be milked at the same time. 

So how do they spend the rest of the day?

A day in the life - cows feeding

Feeding: 4 to 7 hours

Cows are natural grazers, preferring to eat 5 to 9 meals a day, plus drinking. For this reason, cows have free access to fresh food and water throughout the day. 
As ruminants, cows also spend a lot of time chewing and digesting their food – and most of this rumination time is in addition to the feeding time. So while individual cows' behaviour and preferences vary greatly, the time spent feeding and ruminating usually adds up to 4-7 hours a day.(1) 

So just how much does a cow eat? While each cow is different, a typical milk-producing  dairy cow, weighing around 600kg, eats around 29kg of feed each day and drinks over 100L of water (about a bath tub's worth). A cow of this size will produce around 20–40L of milk per day.     

The next question, naturally, is what do cows eat? The short answer is that dairy cows' feed usually consists of a mixture of the farm’s own grass and crops such as corn, oats, or barley, to which essential vitamins or minerals may be added. Learn more about the diet of a Canadian dairy cow.
 

 

A Day in the life - resting

Resting: 10-12 hours 

On average, cows usually spend around 10-12 hours a day lying down (2)  – although they get up and down regularly during this time. But they're not just resting: as ruminants, they're also chewing and digesting their food multiple times (when you have four stomachs, it's a process!)

Cows also use this time to socialize with others in the herd. Canadian researchers have observed that calves create bonds with each other, and that friendship with their companions may be long lasting (3). Like most herd animals, cows also have a status in the herd: some are more bossy, some are more timid, and farmers and herdspeople are well aware of the personality traits of each cow.

Sleeping : 4 hours

With all that time spent resting and lying down, this girl doesn’t need much beauty sleep! Cows naturally sleep for a total of 4 hours a day – and no, they don't really sleep standing up (but you knew that, right?) In fact, some cows are known to sleep curled up, with their head on their belly, while others sleep sprawled out.

A day in the life - inspection

Inspection & Care

In addition to their regular routines, cows are looked after and cared for continually through the day – and sometimes through the night – to ensure their needs are met.  Between milking, feeding, stall cleaning, and other activities, every cow is checked on by the farmer or other farm workers multiple times every day. Farm workers ensure their comfort, and look for any changes in behaviour that may be warning signs of illness or stress. 

All in a day's work

After a day spent eating, drinking, chewing, socializing, and receiving expert care, a Canadian dairy cow can rest easy – and so can dairy consumers, knowing their milk comes from responsibly managed farms, where animal care is a top priority.
