Page 2 of articles about ventilation in Articles

After reviewing some of the main hazards for pork producers in previous articles, this article is devoted to practical measures describing how to reduce risks of illnesses and injuries from those hazards.

This article summarizes the main points to beat heat stress in pigs.

The most direct strategy to decrease the concentration in the air of airborne pathogens is dust reduction. This article describes the use of a particle ionization system called EPI.

Improve the piglets' comfort in the fattening rooms without compromising ventilation by placing an insulating material over the pens.

The use of these nests help create two well-differentiated areas: a warmer one for the piglets and a cooler one for the sows.

It consists in lengthening the towropes of the windows that we want to keep more open.

Micro-sprinklers were installed above the windows in order to reduce the temperature in the farrowing rooms in summer.

The aim of this trick is the improvement of the quality of the environment in the farrowing quarters for the sows as well as for the piglets, saving on energy consumption by means of the manufacturing of nests.

The thermographic cameras can measure the temperature in all the image with resolutions that are equivalent to 19,200 infrared thermometers at the same time.

In high-density swine regions of North America, air filtration is playing an important role in the effort to maintain PRRS free commercial sow herds

One could think that the number of deaths increases in the winter in the northern hemisphere because the animals freeze to death.

Genetic selection over the last few decades has resulted in pigs with better feed conversion and leaner carcasses, but it has also led to pigs with a decreased ingestion capacity.

In order to try to control the environment, it is important: - Be able to evaluate it. - Be familiar with the needs of different types of animals. - Implement corrective measures to adapt to those needs.

Man is possibly the only animal capable of living in practically all places in the world, regardless of the climate. This is due to his capacity to construct buildings to isolate himself from the climate however extreme it may be, maintaining an environment which allows him to survive. As domestic animals live together with man, they have to take advantage indirectly of this capacity.

The most important way of examining the conditions of a building is using ones senses, since these might tell you immediately, whether an environmental problem is present.

In natural conditions, there are seasonal fluctuations of availability of food and the earliness or delay in the onset of breeding is related to food levels.
