Zero-Grazing Dairy Systems and Cattle Welfare

Zero-grazing, or indoor confinement dairy systems, are expanding in the UK and Europe. These systems offer some advantages in disease control and feed efficiency but raise serious concerns about cattle welfare.

Key Facts

An estimated 15-20% of UK dairy herds are now zero-grazing or near zero-grazing
Cows in zero-grazing systems typically receive a total mixed ration rather than grazing
Lying times and locomotion are significantly reduced in permanently housed systems
Automatic milking systems combined with indoor housing are the most intensive form of dairy production

Welfare Considerations

Permanently housed dairy cows cannot perform natural grazing behaviour or experience varied terrain and environment. Lying behaviour is disrupted when cubicle design is inadequate. Social hierarchy establishment is more aggressive in permanently housed groups. The psychological importance of outdoor access is demonstrated by cows showing pronounced motivation to access pasture when given the opportunity. Indoor housing year-round also concentrates disease risk. Welfare monitoring in zero-grazing systems requires particular attention to evidence of restricted movement, environmental frustration, and health outcomes.

What You Can Do

Choose dairy products from farms with documented outdoor grazing days through schemes like Pasture Promise
Advocate for minimum grazing requirements as a condition of dairy farm assurance
Support research into environmental enrichment for permanently housed dairy cows
