StockVent Livestock Building Ventilation

Livestock Building Ventilation Systems

Heat produced by livestock naturally rises. If it is unable to exhaust from the building, it will condense on cold roof surfaces, increase humidity and make bedding damp and cold. This creates a suitable environment for bacteria to thrive.

Not only does this increase the risk of disease for livestock, it also increases heat stress levels which can have a serious impact on productivity, particularly with milk production, as well as fertility, miscarriage and low calf birth weights.

Installing a livestock building ventilation system provides a continuous stream of fresh air which alleviates the effects of heat stress and contributes to maintaining and increasing livestock production levels.

Why use the Martin Lishman StockVent Livestock Building Ventilation system?

StockVent is specifically designed to enhance the quality of the environment in the livestock building throughout each season of the year
StockVent removes moisture, heat and odours generated by livestock, replenishing the supply of oxygen by bringing in cooler, drier air from outside the building
StockVent removes harmful gases such as ammonia, methane and Hydrogen Sulphide which benefits animals and farm workers

Heat Stress

Dairy cows need to maintain a constant body temperature of 38.8°C +/- 0.5°C. When an animal becomes heat stressed, feed intake will decline which in turn will affect milk yield.

There is also likely to be a reduction in fertility and an increase in embryonic loss. An increase in cases of clinical mastitis is often seen in heat stressed animals.

Ultimate Versatility

The Martin Lishman range of StockVent livestock building ventilation fans come in a vast range of sizes and shapes to make them ideal for suiting your existing building.
