How environmental enrichment for dairy cattle reduces stress, improves health outcomes, and supports natural behavior expression.
Dairy cow enrichment is an underutilized welfare tool in many commercial systems. Rotating brushes that cows can self-groom with are associated with reduced cortisol and increased positive social behavior. Pasture access provides multiple simultaneous enrichment opportunities including grazing, social choice, and environmental variety. Simple enrichment additions that cost little but deliver meaningful welfare benefit — brushes, varied substrates, outdoor access — represent high-value welfare investments aligned with production quality goals.
