We will be conducting a free webinar next THURSDAY, May 21, at 9 am (EDT - US). I will be discussing the factors affecting tunnel fan performance and energy efficiency.

Did you know:
1) If you replace a 1 hp motor on a fan with a 2 hp motor you will not significantly increase the power used by the fans.

2) A 1 hp fan motor label has little bearing on its actual power usage.

3) That fan size is one of the biggest factors that determines energy efficiency.

4) Fan measuring amperes tells you little about a fans energy efficiency.

5) Reducing the number of tunnel fans by installing a "high capacity" tunnel fans will lead to substantially higher power bills.

6) Utilizing variable speed tunnel fans can reduce power bills by between 20 and 50%

7) Tunnel fan power usage actually increases very little as static pressure increases.

I will be covering these items as well as many others.

Just thought I would take a moment to share some preliminary chick weight data from our feeder pan light study. 8 pens (four with lights, four without) in the 40 X 500 house. 100 chicks were weighed in each of the eight pens. Average weight of chicks at placement 45.2 vs 45.1 grams, no lights vs lights respectively. 24 hours later 52 vs 51.9 grams. No significant difference.

Feed Pan Light Study - Update. Last flock we divided the house into four sections and gave the chicks in each section free access to both the feed pans with and without lights. The objective of the study was to determine if birds would be attracted to pans with lights. Attraction was determined by monitoring the amount of water consumed by drinkers next to each type of feed pan as well as through visual observations. Though the chicks did appear to be more interested in the feed pans with lights immediately after placement, over the course of the flock we were unable to document a strong preference for the feed pads with lights.

This flock we have divided our 40' X 500' house in to eight sections, four with feed pan lights, four without. We will be weighing 100 birds in each section on days 0, 1, 7, 14, 21, 28. Water usage in section will be monitor on a minute to minute basis.

The images below are of four different sections, two without feed pan lights, two with, taken approximately 30 minutes after chick placement. It was interesting to see that in all the sections with feed pan lights the chicks tended to stay closer to the feeders than in the sections where the feed pans didn't have lights.

05/08/2020

Ok...I know that virtually everyone will disagree with me but here it goes :) Here are some facts that we have learned over the years in our multiple studies on the use of evaporative cooling pads in poultry houses:
1) It only takes about 2 minute of pump runtime to thoroughly wet a pad.
2) After a pump shuts off water will continue to be absorbed by the pad and temperature will continue to decrease...and humidity increase.
3) For every 1 F cooling ...the Rh will go up 2.5% (1 C - 4.5% Rh). This doesn't change if the pad is partially wet or water running over the pad.
4) A 1' section of pad (5' tall) will hold nearly a gallon of water.
5) Once a pad is wet it will tend to produce the same level of cooling/Rh for about 10 minutes.
6) It takes nearly 45 minutes for a wetted pad to thoroughly dry.
7) Most of the cooling occurs inside the pad. The leading edge can be dry and the pad will produce nearly the same level of cooling and Rh
8) Placing a pad on a ten minute interval timer will reduce pad life.

So what is gained operating a pad off a timer? Now if you are trying to limit cooling on younger birds by operating the pads a few seconds out of 10 minutes I have no problem with it. You will get less cooling AND less humidity. But most of the time during hot/humid weather operating a pad off a timer accomplishes less than most beleive. The best way to maximize pad life and bird cooling is simply to rely more on air speed and less on your evaporative cooling pads (set temp around 85 F).

The graph below shows the relationship between incoming temperature and Rh for a pad that came on at 93 F.

05/08/2020

So you think you have a problem with mineral build-up on your pads? The primary cause of mineral build-up on pads is poor water quality. To minimize mineral build-up:
1) Maximize the flow of water over the surface of the pads. To keep our pads clean and slow the rate of mineral build-up we are supposed to circulate 10 times the amount of water that evaporates of the pads. The water flow over the surface should be clearly visible. If you put your hand on the surface of the pad and extend your thumb, a stream of water the size of roughly a pencil should flow from your thumb.
2) Purchase pads with 45 X 15 flute angles. The unequal flute angles increases the amount of water flow over the exterior surface of the pad.
3) Purchase a pad with a quality edge coating and brush the surface of the pad on a regular basis.
4) Dump water from the system weekly basis, daily if you have a serious mineral build-up problem. This helps to rid the system of minerals that will accumulate in the water over time.
5) Do not operate pads on an interval timer. The constant wetting and drying of the pad accelerates the build-up of mineral on the surface of a pad.

Don't forget to register for the fourth lecture in our Hot Weather Management Webinar Series (Tuesday April 21 - 9:00 AM EDT-US). "Answers to the 12 Most Commonly Questions About Evaporative Cooling".

We will address all of these questions...and probably a few more (feel free to provide suggestions):
How much pad should be installed on a house?
Can we increase cooling by increasing pad area?
How does the cooling produced by a pad change overtime?
Does running cold water over the pads increase cooling?
Are plastic pads better than paper pads?
How many fogging nozzles are required for a house without pads?
How many fogging nozzles should I install in my pad houses?
Can I use sprinklers instead of pads?
Should evaporative cooling pads be turned off during a thunderstorm?
Can 10 minute timers on pads reduce humidity without reducing cooling?
Does placing a pad on a 10 minute timer actually reduce cooling and humidity?
Does a pad produce the most amount of cooling just before it dries out?
What causes the litter to get wet near the pads?

This webinar, though hosted through same gotowebinar services as previous webinars it is technically a "webcast" so it will look slightly different but is essentially the same. We are changing to a webcast so we can have more than 1000 participants.

We hope you can join us.

Our most recent Poultry Housing Tip explores the extremely low flow rates in our drinker lines and the very long it can take for birds to receive "fresh" water at times.

"It may be difficult to comprehend, but water actually doesn’t “flow” in drinker lines...it slowly drifts. In a way it is more appropriate to consider the flow of water in drinker lines as a pond more than as a rushing river. This holds true for a house with day-old birds or even market-age birds....for instance, it can take about a day for chicks near the end of a drinker line to receive fresh water "

Just posted our latest Poultry Housing Tip "The Cyclic Nature of Chicks". Through the use of high accuracy water meters on a number of commercial broiler houses we found that there is a fairly consistent 30 to 60 minute feeding/resting cycle that chicks exhibit during brooding. Chances are if the chicks are just sitting around no need to worry, they will probably be up and about in 15 minutes or so.

There is a link to a time lapse video in the Tip that shows the feeding/resting cycle over the course of a few hours that I believe you will find interesting.

Let us know if you have any questions or comments.

This is a time lapse thermal camera video showing a house with Big Foot tube heaters with and without 24" 1/3 hp circulation fans operating (eight in 40' x 500' house). The video shows a 60 minute period in 16 seconds. The first half of the video the circulation fans are on, the second half they are off. A couple of things to take note of:
1) When the circulation fans are operating the ceiling is significantly cooler than when they were turned off.
2) The circulation fans reduce the amount of time the tube heaters operate.
3) Without circulation fans the floor temperatures in the center of the house tend to become much warmer than the birds desire/require.

I hope find this short video of interest.

UGA Hot Weather Management Webinar Series: Heat Stress and How Birds Cool Themselves

Since we needed to cancel our 2020 Hot Weather Management Workshop/Webinar we decided to try something a little different this spring. We are planning to hold a series of webinars (most likely weekly) related to different aspects of tunnel-ventilated house operation during hot weather. The first one will be next Tuesday from 9:00 am - 10:30 am (eastern U.S) and will be hosted by Dr. Brian Fairchild. Dr. Fairchild's topic will be Heat Stress and How Birds Cool Themselves. The webinar is free of charge. In the webinar you will be able to see our Power point slides and hear us over your computer/smart phone. I will be proctoring this session so you will be able to submit questions to Dr. Fairchild during and after the webinar using the gotowebinar software. We look forward to seeing you.

We just posted our latest Poultry Housing Tip which takes a look at the importance of monitoring chick water usage...

"Getting chicks off to a good start is very important to overall flock performance. At no time does a bird grow faster than during the first week of its life. Over the last week of a 42-day old flock, a bird’s weight will increase by approximately a third. In contrast, a chick’s weight will typically increase approximately four fold, possibly more, by the time it reaches seven days of age. Of course, if a chick is going to grow this quickly it has to eat plenty of feed. Research has shown that over the first full day of a chick’s life it will eat approximately 1/4 of its weight in feed. By the end of the first week, a 40-gram chick (0.09 lbs) will eat approximately 0.33 lbs of feed and gain approximately 0.31 lbs, giving it a feed conversion ratio of approximately 1.1 lbs of gain/ lbs. of feed.

This very high growth rate during the first week is only achievable IF the chicks have access to plenty of water. A chick will not eat, and therefore will not grow, if it cannot drink. In the previously noted study it was found that during the first few days of a flock, a chick will drink nearly three grams of water for every gram of feed. By the end of the first week each chick in a house will drink approximately 12 ounces of water. This is over eight times their initial weight in water...."
