A COMPARISON OF TWO URINE COLLECTION METHODS FOR FEMALE SWINE

Six pairs of littermate gilts were used to compare an invasive (catheter) and a noninvasive (tube affixed around the vagina) urine collection system. Urine volume and nitrogen excretion were greater and water retention and urine specific gravity less (P < 0.05) in the catheterized swine. Collection method had no effect on urogenital infection.
