Graduate Student Literature Review: The effect of housing systems on movement opportunity of dairy cows and the implications on cow health and comfort.

E Shepley, E Vasseur,

Intensification within the dairy industry has led to an increase in use of more restrictive indoor housing systems (most commonly tiestalls and freestalls) and less use of the pasture-based housing systems used in past generations. These indoor housing systems are associated with not only a higher level of restriction to ... Read more >>

Making tiestalls more comfortable: IV. Increasing stall bed length and decreasing manger wall height to heal injuries and increase lying time in dairy cows housed in deep-bedded tiestalls.

S E McPherson, E Vasseur,

Poor stall configuration can negatively affect cow welfare by impairing lying behavior and leading to injuries in dairy cows. The comfort of the stall bed in tiestalls is affected by the material components of the stall bed (stall base and bedding), but also by the amount of space provided. The ... Read more >>

Providing an Outdoor Exercise Area Affects Tie-Stall Cow Reactivity and Human-Cow Relations.

Nadège Aigueperse, Elsa Vasseur,

Confinement and restriction of movement are a reality for most dairy cows. Providing outdoor access is one method to increase movement opportunities.
