Moldy hay often won't make a cow sick due to the ability of the rumen to degrade the mycrotoxins found in such feed. You often won't see any issues in your animals, except lower feed intake because moldy hay doesn't taste nearly as good as good hay, however, certain molds can cause issues like aspergillosis or mycotic abortions, respiratory issues, and chronic issues (especially if fed for too long a period) like reduced feed intake, altered rumen fermentability, reduced fertility, reduced productivity, and higher morbidity (incidence of diseases, not death rates). It is much more concerning if you have a pregnant cow that you are feeding moldy hay to than to steers, bulls, replacement heifers or non-productive/dry, open cows. It is also very concerning if you feed such hay to horses, as it can cause serious problems such as colic or heaves.
If you have more "sensitive" animals such as pregnant cows, try to look for good hay instead and either save the moldy hay for those animals which will not be so sensitive to the mycotoxins. Sometimes a producer has no choice but to feed moldy hay to their animals, and often see few problems as a result. Still, it doesn't hurt to keep an eye on them to see if any issues--especially respiratory--come up. If there are issues that come up, contact a large-animal veterinarian and/or a bovine nutritionist to see what can be done to alleviate, prevent or treat the problems that do arise.

yes because cow munare is germs and it can enter the body and make an infection it really depends if the cow has a virus or any thing that would make it sick
Depends on what kind of feed you feed them. If it's just hay and grain, no. Moldy, dusty hay isn't good for horses, but it won't kill them, it'll just make them a bit sick.
You should call Yodel Farm and buy cow/sheep healing potion then go near your cow and use it (press B). your cow should now be healthy!
Yes, see the link on bracken poisoning.
Yes, it can kill you but it is not likely. If eaten it can make you extremely sick.
The cow would get sick.
Yes, some cats can indeed get sick from drinking cream. Cats cannot digest lactose (found in cow's milk and diary) very well, and can become sick.
Maybe this "cow" that you are concerned about isn't a cow at all. Joking aside, if this is indeed a cow and not a different animal, illness like pneumonia or IBR can be serious enough to make a cow too sick to eat, thus not burp up and chew cud.

Yes! Many people say milk tastes better straight from the cow and that drinking fresh milk is wonderful. However, you should know that it sometimes can make people that aren't used to it sick; since it isn't pasteurized it contains some natural bacteria.
No. Too much of the liquid molasses can, though, since it is high in energy content like grain.
if the barn isn't full and the cow isn't sick
