Agitation too fast
Agitation, fermentation
Agitation, power washing
Agitator jets above pit level.

All guessing. Rumors says DDGs in feed. I don't believe it, farmers have fed DDGs for years. Only last couple of yrs had trouble.
Anaerobic activity in pit.
Bacteria and pathogens
Better agitation/feed/and faster pumping operation
Bigger pumps and distillers in feed
Changes in feed
Changing feed rations/using more DDG's
Changing in feed additives
Cheap feed additives
Chemical reaction to something
Common denominator seems to be DDGs.

DDG's in feed not enough pit ventilation to help with air flow or enough air flow to help remove gases.
DDG's in the feed
DDG's in the feed
DDGs or possibly pit additives.
DDGS pit additives
DDGs sulfur in feed rations
DDG'S the amount of bacteria in the DDG's breaking down at a much faster rate than the pit will handle which causes foaming. I don't understand why no one has figured out what is making the barns blow up. I think it’s the corn distillers that makes foam u
DDG's the amount of DDG those hog industry are feeding due to cost.
DDGs usage
DDG's used in feed at high rates.
DDGs, pit additives
DDG's/bakery by-products/BT corn.  Possibly phytase, it has to be something in pigs diet.

Dry only
Ethanol by-products
Excessive agitation and nozzle above surface of manure.
Excessive agitation- nozzle above manure-increase in distillers in feed
Extra methane gases.

Foam started after DDGs came into feed rations
Gas???
Gases from stirring it up.
Gluten in feed
Government conspiracy, global cooling, Share Effect
High content of water, feed make-up, atmospheric conditions
High levels of bakery products in the feed.
higher energy rations
Higher levels of DDG's/bakery products
Hog feed
I believe its is the change in the feeding ration. That hog owners are changing which is changing in the pigs digestion.
I don't know
I don't know
I don't know
I don't know
I heard DDG's
I pump a lot of deep pit barns & liquid levels have been down due to the cool season and farmers haven't had to use sprinklers to cool buildings or animals another suggestion could be over agitation
I think it’s the change in feed, there feeding a product DDGs and I think that part of it.  (DDGs comes from ethanol plant)
Improper manure management.
Inadequate ventilation and methane gas.
Increase feed
Increase use of DDGs
Increased bacteria activity, different bacteria colonies, increased surface tension--increased fiber in diet and other dietary changes.
Increased DDGs in feed.
Increased microbial activity in pit.
It appears to be the increased use of DDG's in the feed.
Lack of pit remedies to keep pits from crusting and foaming.
Lack of ventilation
Last coupled of years, more water ratio to solids
maybe feed ingredients
Maybe too much agitating
Methane
Methane
Methane gas
Methane gas mixing with air.
Mix of feed
More cleaning by customers
More distillers by products in feed
More water in pits
NA open lagoons
Natural cause of mixing
New buildings
New ingredients that are put in hog feed and then in waste
no
no comment
No ventilation
Not enough ventilation
Not enough ventilation
Not seen any foaming
Not sure
Not sure
Not sure-combination of DDGs and pit additives???
Not sure--feed ingredients?
nozzle of pump needs to be under liquid. IF nozzle is blowing on top, it will make foam.
Nozzle of pumping straying on the top of the manure.
Over agitating and feed ingredients possibly
Over/improper agitation
People adding chemicals to help with nutrients and smell
Pit additives because of anaerobic activity due to microbial excretion.
pit pumps
pit pumps
Pit remedies
poor management of building
Possible feed additives, chemical byproducts or reaction.  I do not know why its getting worse.
Possibly pit additives
Possibly the use of DDGs used in feed more than used in past.
Pressure
Products in the feed.
Propellers
pump blowing across top of manure in pit
Something in the feed
Something in the feed and how the hog is digesting.
Splashing pooh
Stir the pit I think causes foaming due to high pressure
stirring
Stirring on top
Stirring too fast or too long.
Temp influx--cool pit manure mixing in warmer air( oxygen introduction)
Temperature changes, cold water washout
The feed.
The feeding of DDG's I the feed.
Too much agitation
too much agitation/distilled feed
Top spot dumping above pit level. RPM of pump should be fluctuated periodically
