Tomorrow will be our fourth presentation in our Tunnel Ventilation Management Webinar entitled "Tunnel House Operation 101". I will be discussing some basic tunnel ventilation system operation principles. For example, tunnel house operation (ie number of fans, air speed) should be based production phase (first 1/3, second third, final third) and not on bird age. Think of it this way. The likelihood a 32 day old bird will become heat stressed depends more on whether it is being processed tomorrow or two weeks from now.

It's not to late to register for this series of webinars. You will have access to recordings of three previous webinars. The cost is only $40 and helps support our educational efforts.

Modern poultry house controllers are capable of recording a tremendous amount of information related to what is happening in a poultry house. The challenge is how best to display the data so that managers can quickly spot potential problems so they addressed before bird performance/health are adversely affected. Having a PC/Laptop connected to the controllers on farm can be a great help in this situation. The key is to display the most important data (temp, rh, water, fan/heater runtime, etc) in a way so comparison between the houses can be quickly made. For instance, on this PC there is a table in the upper left hand corner that displays temperatures (front, middle, rear), Rh, and water usage since midnight. Below it is a graph of the average temperature in each of the seven houses on the farm. On the right is incremental water usage (1 hour in 5 houses, 15 minute in two houses) over the last few days. A quick glance and show temp/rh are fine but there are issues with water consumption in a couple of the houses (red and light blue lines). The hopper fill augers were having issues...no feed...no need to drink water

In high air speed houses (700 ft/min+) you might be interested to learn that removing the pads from a house doesn't significantly change the total static pressure the fans are working against (provided the pads are in like new condition). For instance, in this particular 54' X 500' broiler house with 16, 52" high capacity tunnel fans removing the new pads (2 X 5' X 110') from the house only reduced the static pressure the fans were working against by approximately 0.02". Air speed only increased by 50 ft/min (800 ft/min from 750 ft/min) when the pads were removed. The fact is the higher the air speed the higher the static pressure will be...with or without pads.

Something as simple as installing plastic sheeting over exposed wooden studs can result in significantly higher wind speeds along the side walls in a tunnel-ventilated house. The smoother the side wall, the easier it is to keep birds cool along the side wall.

Water flowing over the surface of an evaporative cooling pad serves two proposes: To wet the pad and to keep the pad clean. To wet a pad requires a relative minimum amount of water (typically around 0.06 gals per linear foot of pad). But to clean a pad requires roughly 10 times the flow rate (0.75 gals per linear foot). The amount of water spraying up from the distribution pipe in this video may be enough to keep the pads wet it is definitely not enough to keep the pad surfaces clean and free from minerals.

I have probably examined nearly 100 poultry houses that have "failed" over the years. One of the things I have learned is the importance of a proper knee brace in reducing the risk of house failures due to high winds. A knee brace is small but essential structural component especially in concrete stem wall houses. A "toe nailed" 2 X 4 would not be considered by most engineers as proper knee brace due to the fact that there is very little holding them in place. A far superior option is an angle iron knee brace lag screwed in the the side wall and truss. If you have toe nailed 2 X 4 knee braces, please consider replacing them.

I know it sounds like a silly question but are you sure your lights are going off at night? The problem is that most broiler dark periods begin around midnight and end before six am making it unlikely that anyone will actually experience the dark period. We have documented on multiple farms having performance problems that the lights were not going off at night and hadn't been on some farms for multiple flocks. A number of research trials have shown that 24 hours of light results in significant reductions in broiler performance and health. One of the advantages of modern controllers is the ability to generate water usage graphs on a 15 minute or hourly basis. These types of graphs make it clear when the lights went off and came back on. If you don't have this type of controller and you are having performance problems do yourself a favor and once a flock double check your lights are actually going off when you believe they are. You may loose a little sleep, but you might also find the cause of your production problems.
