Urine Specific Gravity

Ok... Georgie's SG was 1.015. He's elderly and has kidney disease and is on 25 cc's of SubQ fluids daily. Good news - he has gained 25 grams since I started the fluids! Still skinny though - 640 grams.

Oh yeah... forgot to mention. Doc says he has never seen a pig with a SG lower than 1.010, but that's just him.

I might be taking my two to work with me on Friday just for a visit. If I'm not horribly busy, I'll try to get a SG on both of them. It will be interesting to see what concentration 2 young, healthy pigs have.

Artoo's today was 1.01. He was in for weight loss, possibly calcium related.

Ok....I almost forgot. A while ago I took one of my female fosters in to check her urine since I noticed a tiny bit of red discharge. Everything looked great. I think her SG was 1.030. I THINK. Might have been 1.020. But I'm really thinking 1.030.

Both healthy, 4 1/2 month old females:

Shaina: SG of 1.007 (I checked a sediment - no infection)

Pumpernickel: SG of 1.025

Very low on Shaina! Now that is interesting, is it not? I'm wondering if all these pigs that are supposedly in kidney failure are normal, just that they were extrapolating?? Hm.....

Although, your other pig was up there. Ollie's was 1.004.

so what is all this telling us?

That it truly varies from pig to pig? Shaina is a water drinker - eats a bite or two of pellets, has to get a drink. Eats some hay, has to get a drink.

With as much water as pigs drink, I think the only true way to know if the kidneys are actually functioning is to check a SG, then give absolutely no water for 2 hours, check another one. If the kidneys are functioning, the SG should go up. If not, the SG will stay the same.

Otherwise, if Shaina was an older pig, with a SG that low, the first thought would be kidney disease. When I get a chance, I will do the water restriction thing on her, just to see how high it goes. Not that I'm worried about kidney disease, I just want to see what the possibilities are with water restriction.

Digging this back up. Mable's was 1.005 on 6-18-04. Has anyone found any publish norms yet?

So, wouldn't a younger pigs' be higher, i.e. they are concentrating more? Or a pig in heart failure?

We have new babies (they were a suprise, I thought Mama pig was just still s-t-r-e-t-c-h-e-d from the previous litters) I could try to take them in to see what babies are comparitively. My vet's game to do it.

It's a rescue pig, just in case anyone was wondering.

If you look back, one of my girls had a low specific gravity at a young age. She was also my water drinker. Now that she isn't as much, I should recheck the both of them again, after withholding water for an hour.

Mel, how does the vet or the tech actually do the test for specific gravity? What does it involve? If I have to take my sow Muffin back to the vet again, I'd be interested in getting this done out of interest.

It's just a matter of getting some urine (it can be sucked off the table), and putting a drop on something called a refractometer. I don't think specific gravity changes over time, so if you bring some from home that you've gotten during the hour before you go to the vet, that should be fine.

Okay, mel or others.

My pig had urinalysis today (among other test) and had 1.007. Blood enzymes don't indicate kidney troubles, but he isn't well and we can't find the cause outright. His info is here.

He probably hadn't had water for some time, since he'd been anesthesized for x-rays and a tooth exam, but I have been fairly aggressively syringing water for the last 1.5 weeks due to his anorexia. He seems well-hydrated and doesn't seem to pee excessively, but what do I know?
