Wind speed in the barn or ventilation of the barn is the most important factor in animal husbandry, especially industrial breeding with closed model. However, this factor has not been noticed by many producers.

THE ROLE OF THE WIND IN PIG FARM

The ventilation in the barn directly and deeply affects the growth, development and development of pigs in all stages, breeds of pigs. Because wind speed is the central factor that governs and controls other pig habitats such as temperature, humidity, oxygen content and toxic gases in the air … When the wind speed is low, the content The oxygen in the barn is not enough instead of toxic gases which are the product of the process of decomposing wastes such as: NH3, H2S, CO2, …

Low wind speed for a long time will cause piglets to grow slowly, reduce resistance, or suffer from respiratory, digestive diseases or can kill piglets by suffocation. Boars reduce sperm quality or may lead to infertility. Pregnant sows are prone to miscarriage or stillbirth due to insufficient oxygen providing pregnancy support. Stress-rearing sows lead to loss of milk or reduced milk quality causing diarrhea in piglets. Moreover, when the wind speed is not reached, it often attracts the temperature factors, inappropriate humidity will increase the consequences. Low wind speed makes pigs susceptible to stress, reducing the general resistance of cattle and an opportunity for outbreaks.

Especially for farms that have experienced outbreaks of PRRS, FMD or PED, wind speed has not been achieved as a major cause of outbreaks again. In these camps, pathogens cannot be completely destroyed but still hidden inside the farm inside the pig body, barn floor, the tools of breeding even in the air. When the level of ventilation is poor, other environmental factors are not suitable to make pigs stressed, the resistance decreases. This is an opportunity for pathogens to proliferate, grow, and re-explode and damage is very serious. Because the pig itself carries the disease, it does not have the best resistance in combination with stress due to environmental factors that make the pig’s body protection barrier paralyzed, so when the epidemic occurs often quicker and stronger.

Application of composite fans for pig farms:

• The fan is made of composite material capable of absorbing hot air and has the ability to cool, adding moisture to help improve the surrounding environment effectively.
• Composite industrial fans are often used in most livestock farms, such as pig farms, chicken farms, or in areas with metal corrosion
• With easy installation on the wall, this type of fan is often used for ventilation in factories. Composite fans can be used in cooling systems of factories by combining cooling pad with pad, used to suck hot air inside the factory out, making the factory airy, making the air always fresh.
