UTI in gilt?

[Cricket]

I noticed 2 weeks ago one of my gilts standing with her head in the corner of their house and peeing towards the middle--usually they pee IN the corner. Then during a cold snap, noticed she had frozen pee on her butt hairs and a wet tail. Her girl parts, which are usually pink, looked like raw white fish. Finally figured that she's been dribbling urine instead of peeing a stream, and the white was kind of a dishwater hands thing). I am assuming UTI? The first day I gave her 1/2 cup ACV, 2 vit c, and yogurt and by the next day she peed a short stream and her girl parts are returning to normal. This is the 3rd morning and I still see some evidence of dribbling, but much better. Any thoughts?

I hate to go the antibiotic route, as I want to keep my butchering option open. Other than that, she seems fine, active, eating, etc. She had had runny poop before this started for 2 days, but am pretty sure it was too much cow colostrum.

Well, to update, Flash's urine dribbling never improved to any great extent. She never seemed sick or straining, and don't think I would have noticed in the summer (no icicles). She would pee in streams also. I butchered her at 6 months old and she dressed out @ 127lbs. The butcher and I poked around and couldn't really see any obvious weirdness, other than one of her kidney's had an odd little dent in it at one end. (Would look like the crease on the inside of your finger when it's open). Also no signs of worms in her intestines.
