Do cows prefer a barn compartment with a grooved or slotted floor?

Area of Science:

• Animal Science
• Agricultural Engineering
• Behavioral Science

Background:

• Dairy cow housing design significantly impacts animal welfare and productivity.
• Understanding cow preferences for flooring is crucial for optimizing barn environments.
• Previous studies often lack detailed behavioral analysis in controlled preference tests.

Purpose of the Study:

• To assess Holstein-Friesian cow preferences between longitudinally grooved and perpendicularly slotted floor compartments.
• To analyze the impact of different floor types on cow activity budgets and behavior.
• To evaluate the influence of floor design on cow relocation and resource use.

Main Methods:

• Two identical barn compartments with distinct floor profiles (grooved vs. slotted) were used.
• Sixteen pregnant, lactating Holstein-Friesian cows were habituated for 14 days.
• Cow behavior, time budgets, and resource use were videotaped and analyzed over 10 days.

Main Results:

• Cows spent an average of 120 minutes longer per day in the slotted floor compartment.
• All daily activities were performed significantly longer in the slotted floor compartment.
• Individual preferences varied, with five cows preferring slotted, two preferring grooved, and nine showing no preference.

Conclusions:

• While cows spent more time in slotted floors, no single floor type was definitively preferred by all individuals.
• Floor profile influenced drinking posture, with cows preferring to stand parallel to slots.
• Concentrate dispensers, rather than floor type, appeared to be a greater driver of cow relocation.
