The purpose of a minimum ventilation system is to bring in small amounts of cold fresh air into a house and to warm it as much as possible before it moves down to floor level so as not to chill the birds and to maximize the litter drying potential of the incoming air. Traditionally, poultry producers have utilized a “negative pressure” minimum ventilation system. In a negative pressu ...

Lee Baxter The minimum ventilation calculator is good for anytime during the flock to provide an estimate of how much you should be ventilating based on water consumption and inside/outside conditions. Technically during the night when temperatures are lower minimum ventilation rates tend to decrease...this is something you can experiment with the app. During cold weather the changes in theoreti ...

Why does litter seem to suddenly cake over just prior to turning the birds out into full house? In many cases, it is simply because minimum ventilation fan settings are not being changed quickly enough to keep up with the rapidly increasing amount of moisture the chicks are adding to the litter. This often occurs because suggested minimum ventilation fan settings are often provided in terms of a ...

I like the article very much, it follows simple theory: chicks are like small kids and the first few hours, first two days, are very important in its life cycle in which their behavior is decided out of which eating and drinking behavior is more important. This would decide about the flock uniformity and the growth pattern of the flock.

High ammonia affects broilers in many ways. Research has shown that ammonia concentrations as low as 25 ppm can reduce bird weights at 28 days of age by two to seven percent while 50 ppm ammonia has been shown to reduce bird weights from 16 and 19 percent (F.N. Reece et. al., 1980, D.M. Miles, et. al., 2004). Ammonia exposure has also been shown to reduce feed conversion by approximately one poi ...

Getting chicks on to feed and water as quickly as possible after arrival on a farm has long been recognized as the key to maximizing overall performance. If provided the ideal environmental conditions and plenty of feed and water, chick weights should increase by roughly 50% during the first 48 hours compared to only 2% over the last 48 hours of the flock! Quite simply, the less time it takes ch ...

Andy G Tuazon; Dr. Tuazon, I have not used the Gastec ammonia detector. We have used the following hand held detectors, Drager, PAC 7000, 3-M's Single Gas Detector model 450-455-104 A, and the Honeywell gas detector model 128-266-1-3. These gas detectors are available from the Grainger distribution company 9avaiable on line). All of these models can detect the ammonia, however they assay only for ...

When building a new house or retrofitting an older one, tunnel fan selection is one of the most, if not the most important decision a producer has to make. A house’s fans are essentially the engine of the ventilation system and as a result have a significant effect on a producer’s ability to maintain the proper environmental conditions throughout the year. Furthermore, with rising elec ...
