1,000-Cow Modern Free-Stall Dairy Housing & Ventilation System
Designed following University of Wisconsin Dairy Modernization guidelines and German DLG animal comfort criteria. This complete dairy infrastructure package maximizes resting time (target ≥ 12–14 hours/day) and milk production via ergonomic 3-bend free-stall loop dividers, Jourdain-style anti-choke self-locking headlocks, high-volume 54-inch BESS-tested tunnel ventilation fans, and rapid-refill constant-level stainless water troughs located in every cross-alley.

Resting Physiology & Milk Yield Correlation
High-producing dairy cows require 12 to 14 hours of daily lying time to optimize rumination and mammary blood flow (approx. 400–500 liters of blood per liter of milk). Inadequate freestall loop dimensions cause perching, bruised briskets, and hock lesions, cutting milk yield by up to 2.5 kg/cow/day. Our 4-bend ergonomic loop divider preserves an unobstructed 600mm forward lunging envelope, allowing the cow to transfer her center of gravity forward naturally when rising without striking horizontal steel rails.
Heat Stress Abatement & Microclimate Physics
At Temperature-Humidity Index (THI) levels above 68, dairy cows experience reduced feed intake and decreased conception rates. Our tunnel ventilation matrix integrates 36x 54-inch BESS-tested SMC fiberglass cone fans producing continuous 2.0–2.5 m/s air velocity directly across resting beds, paired with high-capacity cross-alley waterers providing 9cm linear perimeter access per cow with rapid 60 L/min refill capacity.
Biosécurité, Lavage et Maintenance Préventive
Désinfection chimique, graissage des pivots et contrôle régulier.
Check torque on all two-piece ductile iron cross-clamps (M12 grade 8.8 galvanized bolts) to prevent neck rail sagging or divider twist.
Drain and brush out stainless steel water troughs twice weekly using the quick-turn drain plug; verify heating thermostat operation before winter.
Wash dust and down feathers from 54" fan propeller blades and butterfly shutter hinges every 60 days to maintain maximum CFM/Watt efficiency.
Questions Fréquentes Projets Clé en Main & Export
Q1:How do you coordinate freestall mounting with existing barn concrete curbs?
We provide two mounting options: embedded stanchion posts cast directly into new curbs (300mm depth), or heavy-gauge baseplate stanchions with M14 stainless wedge anchors for retrofitting existing dairy barns.
Q2:Are the self-locking headlocks safe for horned or large-framed Holstein cows?
Yes. The Jourdain-style safety headlock features adjustable neck openings (160mm to 220mm) and an emergency bottom release that opens down to 420mm if a cow goes down during veterinary lock-up.
Q3:What electrical voltage is required for the 54-inch ventilation fan motors?
Our 1.5 HP TEFC motors can be wound for 380V/400V 50Hz 3-phase, 460V/480V 60Hz 3-phase, or 220V/240V single-phase to match your local agricultural grid specifications.
Complete factory export package costs ~$115,000–$128,000 CIF (approx. $115–$128 per cow space), compared to European/US quotes of $240–$310 per cow space (saving >55% on mechanical equipment CAPEX).
