No, if it is canned, it is pasteurized and the probiotics are dead. I was thinking homemade, but I can't keep track of who ferments and who doesn't here, sorry!
You can use the whey from Stoneyfield Organic yogurt for some live culture probio's, simply dump a quart of plain in a cloth-lined colender (I never remember how to spell that!) over a bowl to catch the drips. I use a piece of t-shirt material, it works great. Leave it at room temp for a few hours, the warmer it is, the faster the whey comes out. I fold the corners of the material over the yogurt just to keep the ever-present floating cathairs out of it.
You can mix the first couple tablespoons of whey into something she will eat readily, but I avoid grain and anything my girls aren't used to when I see dog poo.
The yogurt will continue to drain, save the whey in a glass jar in the fridge or freeze it in an ice cube tray for future use, the probiotics should be good for 3-4 months in the freezer. That is how long cheese cultures remain viable this way, so I figure yogurt cultures are the same. You can tie the material corners over a fork or knife and hang it in a pitcher and put it in the fridge overnight, and it will continue to drip whey. You will get quite a bit, and a lovely thick yogurt cheese that can be eaten with fruit or herbed and used for a dip.....super yummy!
I would give her probios every few hours until she is back to pooping pellets.
I give my girls a shot of probios regularly "just because" in the form of homemade sauerkraut, the older the better, and I soak their whole barley in water and whey so they get some probios with every meal. I do tend to be a little obsessive this way, but it works. I can feed whatever free stuff I can get my hands on....pumpkins, squash, old carrots, pine trees, etc with no disruption of their digestion. I give some to all my critters regularly to keep everyone super healthy. I give kefir to the house pets and the chickens regularly, as I often have an excess because it needs to be refreshed every day.
Hope this helps. You can purchase probios that work just fine, but since animal products are not as regulated as human products and there have been so many contamination problems, I prefer to make my own.
I am a nervous wreck about the whole lambing process. Reading on the subject is not helping, my husband thinks all will be fine but after losing the lamb earlier this year to coyotes I am feeling like a sheep failure
