Cow Sounds and Vocalizations

Cattle are highly vocal animals that use a variety of moos, bellows, grunts and other sounds to communicate with each other and their human caretakers. While the classic “moo” is how a cow’s voice is popularly depicted, cattle actually have an extensive range of vocalizations that serve different social and functional purposes.

In this blog article, we will explore the meaning behind common cattle vocalizations to help you better understand these farm animals when they are trying to express themselves.

The Most Common Cattle Sounds and What They Mean

Cattle use vocalizations for crucial communication. Here are some of the most frequent cow noises and what they signify:

The Classic Moo

Cattle most typically vocalize with moos, which almost sound like “oooo” or “boo.” A standard moo is a moderately loud call that generally means a cow is trying to locate other cattle or reconnect with her calf if they get separated.

Cows also moo when experiencing stress from factors like weather changes, illness, unfamiliar environments or social hierarchy disputes within the herd. So while the classic moo often gets portrayed in fun ways, it can indicate a cow’s distress.

High-Pitched Bellows

Both cows and bulls emit loud, higher-pitched bellows in excited states or to signal strong emotions. For example, a cow separated from her calf will release loud bellows as she tries to call it back to her.

Bull bellows are most intense during the mating season. As bulls compete for female attention, they vocalize bellows to threaten rival males and signal their prowess to cows.

Rumbling Lows

Cattle also use deeper, rumbling moo sounds typically called lowing. Lows are lower-pitched vocalizations cattle make to find each other, signal contentment or express interest around food anticipation.

For example, cows may start lowing when a farmer enters the barn to distribute hay, connecting the sight and sounds with the promise of an upcoming feeding.

Snorts and Grunts

Cattle frequently use snorts and grunts as self-preservation fear reactions or to display aggression towards hostile animals or people infringing on their space. They forcefully exhale through the nostrils to produce these abrupt, rough noises.

When startled, cattle often snort loudly, then retreat. But consistent or threatening advances can cause aggressive snorting, head-lowering displays, and ultimately horn or head-butting attacks for self-protection if the cow feels cornered and unable to escape the perceived threat.

Bawling in Calves

While adult cattle have a recognizable vocabulary of communication sounds, newborn calves instead emit a loud, sustained vocalization called bawling. They bawl at extremely high volumes to call to their mothers when hungry or scared.

This vulnerable stage of a calf’s life requires gaining its mother’s urgent attention to be fed and protected from any predators that may be nearby.

Loud bawling ensures the best chance young calves have at survival. It allows the mother cow to find her calf quickly and nurse it.

Vocalization Volume and Meaning

The volume of a cow’s vocalizations provides additional communication context beyond just the type of sound itself. A cow that moos softly may simply be locating a herd-mate nearby, while louder moos can signify anxiety levels due to external stressors.

And the volume of certain sounds like bellows demonstrates how excited or in “heat” a cow may be during the breeding season. The louder the bellow, the stronger their mating urge essentially “advertises” to potential suitors.

Cattle also increase their vocalization volume to compensate for loud environments. In noisier settings like auction houses, cows needing to connect over greater distances must moo or bellow more powerfully for their calls to be audible.

How Cows Use Vocal & Non-Vocal Cues

While cow vocalizations provide direct communication, cattle also utilize body language and environmental cues. For example, mothers returning from feeding may first check if their calves are peacefully resting vs. emitting distressed calls.

Cows also investigate areas where other cattle congregate, relying on herd vocalizing and movement to locate resources like food, water and shelter. And cattle often sniff the ground or air to detect pheromones signaling where herd-mates traveled.

Why Understanding Cattle Vocal Cues Matters

Failing to recognize cow communications can negatively impact cattle health and commercial outcomes like meat and milk production.

Missed Calf Distress Signals

If dairy farmers consistently overlook newborn calf vocal cues from illness or separation anxiety, this reduces weight gain and milk production capacities later on. Missing a nursing opportunity due to a missed calf call can impact long-term growth.

Overlooking Cow Discomfort

Dairy cows unsettled by facility temperature, breeding activities or social angst may moo more from discomfort. Ignoring these environmental stress signals can enable declining health issues like infertility or mastitis infections to emerge. Catching and addressing concerns promptly is essential.

Increased Caretaker Injuries

Agitated cattle getting impatient due to hunger or heat may snort threateningly or head-butt their caretakers. Being attuned to emerging aggression vocalizations like excited bellows allows farmers to adjust spaces to avoid dangerous encounters.

How Farmers Can Optimize Cattle Welfare

Incorporating the following best practices allows farmers to pick up on vocal cues that cattle use to express their needs:

Provide Comfortable Housing

Ensure cows and calves have climate-controlled shelter and non-slip surfaces to prevent distress vocalizations. Monitor for signs like increased mooing that signal discomfort.

Facilitate Social Bonds


Cattle are herd animals, so enable cows to intermingle and form social bonds that are important for their well-being and finding herd-mates when separated.

Keep Families Together

Since distressed bellowing erupts when mothers and calves are apart, keep offspring with their mothers during transfers like auctions. Absent this, place calves that must be solitary in enclosures limiting visual and auditory stimuli to avoid bawling.

Limit Handling Stress

Use calm tone of voices and movements when directing cattle through farm tasks like milking or veterinary exams. Be alert to fearful snorts or agitated grunts to adjust handling accordingly.

Conclusion

Cattle vocalizations might all sound similar to casual observers. But in reality, cows utilize a diverse array of moos, bellows and other sounds to effectively signal their needs.

As the research continues demonstrating how optimizing welfare boosts commercial returns, farmers should hone their listening skills to pick up on the meaningful cues embedded within cattle communications.

Detecting emerging vocal distress quickly allows agricultural workers to remedy issues promptly. This reduces economic risks posed by declining meat or milk yields that stressed, unsettled cattle can experience. Understanding cattle communications ultimately benefits both bovines and business.
