I don't think that you will find any!

Modern farming methods often involve freezing vegatables at the site where they are grown. The nutritional content is therefore higher than ‘fresh’ vegetables that have been transported some distance and then sat around on the shelf in a store for a few days. Also ‘fresh’ vegetables have often, depending on the season, been stored in chilled rooms for days (maybe weeks I believe?)

There is loss of ‘quality’ but that is subjective i.e. we don’t like soggy fruit/veg because it doesn’t have the customary ‘crunch’ or whatever. This is caused by ice crystal damage to the cells of the fruit/veg and has little to do with nutritional value. Pigs are able to make this subjective assessment for themselves too and might not eat the stuff, I don’t know.


BUT this isn’t the only issue. When frozen food is thawed the bacteria (which have only been dramatically slowed down not stopped by the low temperature) start to multiply very rapid. That’s part of the reason for ’Once thawed do not refreeze’ instructions on frozen foods.

It’s the bacterial content that I would be concerned about not the nutritional value. If you are looking for scientific evidence you may be best to read any literature on food spoilage and the bacteria that cause it (can’t think off the top of my head veg v. meat specific bacteria but I would guess that a gamut of nasty things E. Coli, Salmonella, botulism etc are possible on frozen veg). I’m fussy in the kitchen and I am really wary of frozen foods that are not for re-cooking i.e. fruits, ice cream cheesecakes etc.


So...my thoughts are that if you find any scientific evidence it will show that it is both safe and nutritious to offer pigs cooked frozen veg.

Would they eat it? Why would you want to feed it? Perhaps the answer would be 'in an emergency' - but my worry here is that it would be a sudden change in diet and that could cause problems in itself.
