Grooming brushes help feedlot cattle stay calmer and more sociable, study finds

Feedlot cattle with access to grooming brushes are generally more content, sociable and have less stress, according to recent research out of Murdoch University's Center for Animal Production and Health.

They also have reduced aggression, suggesting brushes may permit a more harmonious feedlot environment.

Associate Professor in Animal Welfare and Ethics, Teresa Collins said her team had investigated ways to improve the welfare of cattle in feedlots, focusing on approaches within routine farming systems.

"There is an increasing trend to prepare beef cattle for market in feedlots in Australia, with numbers sitting above 1.4 million in 2024—and these can be regarded as barren environments when compared to pasture-based farms," Associate Professor Collins said.

"Our team investigated how to improve the welfare of cattle within a feedlot context, in a way that is relatively practical to implement. We found that installing cattle brushes can be a simple and cost-effective way to improve their welfare, without leading to negative impacts like reduced weight gain."

The study, published in the journal Animals, looked at the behavior and production of about 170 cattle in a feedlot, comparing those in pens with enrichment in the form of a large, upright cattle-grooming brush, and those without, over 100 days.

Cattle with access to the brush exhibited a more positive demeanor than those with no brush.

The research team was surprised to find the frequency and duration of brush use did not decrease over the study period, suggesting the cattle valued this form of enrichment for providing long-term mental and physical stimulation.

"Interestingly, the cattle were also observed to engage in play behavior more frequently. As cattle are a social species, this is an important sign of positive well-being," Associate Professor Collins said.
