Air quality in a rabbitry.

[grumpy]

I did some quick calculations on the environment within the rabbitry.
I'm always concerned about the air quality in the two rooms that hold the rabbits.

I've got 12,800 cubic feet of air space in both rooms.
I'm not sure what the appropriate rate of air-exchange would be for rooms this size.

Anyways, I've got 3 large furnace blowers exhausting 1500 cfm.
One larger blower motor bringing in 2000 cfm through the swamp cooler.
And two large 24" barrel fans moving 8200 cfm within the rabbitry.
There's an additional 4 smaller fans moving and exhausting air at around 1200 cfm.
Add two a/c units for a combined btu total of 17,500 exchanging air in the rabbitry.

Added together, these fans move "in" "out" and "around" approximately 23,200 cfm.
To me, this seems to be adequate air circulation for the number of rabbits I keep.
I would prefer "more" during the warmer months of the year but I lose the cooled air at a faster rate than I can produce.

In other words, about every 45 seconds, the entire volume of air is exchanged in the rabbitry.

BTW: Yes...My electric bill is 'healthy' during the summer months.
But, I don't lose any rabbits (especially does) to heat prostration.

I believe air quality is THE most important aspect in keeping an indoor rabbitry.
It sounds to me like your turnover rate is outstanding.

I would project here, that you don't "smell" your rabbitry when inside at all, even with the numbers that you keep. If there is no smell, you are doing it right.

My question to you is, how do you keep it from being too drafty? Obviously there is good air flowing, but what do you do to keep those rabbits closest to the inflow from being in a constant breeze? It has been my experience that those rabbits who have a fan on them constantly are much more likely to develop respiratory infections. Just curious.
