How does cow sleep

As part of a recent study a hour cow watch was conducted in the Miner Institute dairy barn to record cow behaviours, writes Alyssa Couse. This involved watching from a runway above the pen, also called a catwalk, and recording mouth behaviors, body positions and location within the pen in minute intervals.

Investigating cow sleeping behaviors was inspired by a question from a colleague during a midnight to 4 AM cow watch shift. It was simply, do cows sleep? Room and comfort should allow cows to transition between the three stages of wakefulness. During my investigation I found that little is known about sleep in cattle.

One possible explanation for this is that when cows spend more time eating, there is less time for other activities such as sleep. The uptick in REM sleep in peak-lactation cows could be compensating for the total reduction in sleep time that occurs after parturition due to the rise in energy requirement and dry matter intake.

While there are still many questions to answer about sleep in dairy cows, from what we already know from other species, sleep is likely critical to welfare. For example, mice exposed to a hour sleep deprivation had a drop in B lymphocytes.

In general, the body goes through a proinflammatory state at night when you are asleep, but during the day when you are awake, it promotes an anti-inflammatory environment. This proinflammatory state is beneficial in moderation as it helps initiate the secondary immune response to help fight pathogens.

The anti-inflammatory state helps regulate and calm down the proinflammatory environment ensuring the body does not undergo an autoimmune response where the body starts attacking its own cells. Studies show that sleep deprivation increases the proinflammatory state leading to chronic low-grade inflammation. In turn, this lessens the effectiveness of the immune response.

Even a few hours of sleep deprivation elevates the risk of cardiovascular disease, cancer, and the common cold in humans.

From a dairy animal standpoint, sleep deprivation will likely alter immune function causing cows to shift resources away from production. Stall availability, stall design, and social hierarchy are just some of the factors that can affect the amount of time cows spend lying down, but it has yet to be established how these factors influence sleep.

Lying time has the potential to impact milk yield and production, but the next step is to understand the dynamic between duration of lying and total sleep time. As data continues to build on the importance of sleep, strategies that can improve health, welfare, and overall production should be factored into management decisions. This is half the amount an adult human sleeps each day. Cows usually don't sleep 3.

A cow takes frequent naps throughout the day and especially the night, whch typically last between one and five minutes at a time, according to an article published in the May issue of "Applied Animal Behaviour Science. Cows need weatherproof stalls filled with soft, comfy material for them to lie on when they sleep.

This bedding material must provide your cows with uniform support for their large bodies, stay dry to prevent the growth of pathogens and have a nonabrasive texture that won't scratch their skin. Common bovine bedding materials include paper, sand, compost, sawdust and straw.

There are even waterproof cow beds available that are stuffed with soft materials inside, although cows tend to prefer some traditional bedding placed on top of them to lie on.

You need to change a cow's bedding frequently to prevent it from becoming dirty and moist, which encourages harmful microorganisms from festering in it.

To obtain a sufficient amount of rapid eye movement sleep, which is the deepest and most important type of rest, a cow must be able to lie down and have enough room to do so.
