Moldy Feed OK?

Post by NonTypicalCPA » Sun Sep 02, 2018 5:29 pm

I bought a 3 ton feed bin this spring and had it filled with a mix from our local mill. I’m starting to get some mold in the feed. First, is it normal for feed to get a bit moldy in a bin if not feed quick enough? Second, can I feed it to my cows and calves? I’d guess the worst of it contains mold on 30-40%.

I don't know about cows cause I've never tried it, but moldy feed will kill a chicken.

Mycotoxins from the mould can be extremely hepatotoxic causing irrepairable liver damage. A poster on here from Australia, Dianna who may still be lurking lost some bulls a few years ago by feeding them the dreggs from a silo.
As to being normal to get mould, no it isn't. I have a small 4 tonne fibreglass silo I mostly use over winter and will have feed in it all over summer and the feed will be just as good when I start drawing from it in autumn.
You must be getting some moisture in to go mouldy. What is the bin made from? I have been a bit dubious of the plastic ones for sweating although mine being fibreglass is glass reinforced plastic and I have no trouble. Was the feed you put in it high moisture to start with.

Looks like I’ll throw out the rest of it. This is a brand new steel bin from Brock.

I’ll also call the mill and see what they have to say.

What kind of feed was put into the bin and how long was it there? Just because it is new, does not mean it CAN'T leak.
In order for it to mold - it has moisture. Either from before it was put it or after.

Doubt you'll get much out of them. Feed could have still been warm if it was a pellet and then sweated after being put in the tank. And there is always the possibility of a small leak somewhere. Feed usually sticks to the side of the tank where there is a leak.

Folks that store grain long term usually blow air through it when the weather changes. Bottom unloading feed bins are not set up that way.
Worst thing in the summer is a grain mix that contains a lot of molasses. Don't ask me how I know. Mold usually means wrong mix for the amount of humidity.
OK to feed depends on the animal and the amount and the type of mold. Talking heads say send in a sample for testing...

DO NOT feed it to pregnant cows, particularly in the last trimester, from what I hear.

Can you take/post a picture of it? I find if it was wet enough to stick it's garbage, a little mould here or there I haven't had problems with

Most all feed down this way has a warning on the guaranteed analysis tag "Do not feed molded or insect infected feed to cattle".

I have a bin about like yours. I putDDGS in and it takes 6 months sometime before I feed it all. Never have had that problem.

If the mold is a result of Aflatoxin it can result in a reduced appetite, reduced growth or milk production, rough hair coat, immunosuppression as well as many other possible symptoms. Depending on interactions with other mycotoxins (realizing that when mold is present there are probably several different mycotoxins being produced), aflatoxin concentrations as low as 100 parts per billion (ppb) may be toxic to beef cattle.

Here’s some pictures. The worst is the clumped up stuff which I throw out. It is a sweet feed with molasses.

Sweet feed has a very short shelf life...even if purchased in 50 lb. bags.
