🐄 Dairy Cow Dry Period Welfare 2025

The often-overlooked welfare issues of the non-lactating period

Overview

The dry period — the 6-8 weeks between lactations when dairy cows do not produce milk — has significant welfare implications that receive less attention than lactation welfare. Drying-off (cessation of milking) causes udder engorgement and pain in high-producing cows. Dry period nutrition, housing, and management directly affect the welfare of the subsequent lactation through impacts on transition health.

Drying-Off Welfare

⚠️ Abrupt drying-off in high-production cows (above 25L/day): causes significant udder discomfort and elevated intramammary pressure for 3-7 days
⚠️ Behavioral indicators: restlessness, reduced lying, increased udder inspection post-drying in uncomfortable cows

Research from University of Guelph and Wageningen has documented that drying-off is painful for many cows, particularly those still producing large volumes. Strategies to reduce dry-off pain: reducing production before dry-off through dietary manipulation (reducing energy and water), administering NSAIDs at dry-off, and in some cases using gradual milking reduction over several days. Pain assessment using validated scales at dry-off shows that welfare intervention is frequently needed but rarely provided.

✓ NSAID administration at dry-off: reduces behavioral pain indicators for 3-5 days; low cost relative to welfare benefit

Dry Period Housing

Dry cows are often housed in lower-quality accommodation than lactating cows — a welfare error given the nutritional and social management required during this critical period. Good dry cow welfare requires: adequate space (avoid overcrowding), clean comfortable bedding (dry cows lie 12+ hours daily), appropriate nutrition (avoiding over- or under-conditioning), and social stability (avoid excessive group changes that cause social disruption during pregnancy).
