The experiment consisted in assessing the effectiveness of a commercial product based on cranberry extracts (pHDReg.-Biomin LTDA) in the treatment of urinary tract infections (UTI) in sows. Were used 42 sows, with gestational ages ranging between 50 and 70 days, either suffering from UTI or not. Healthy animals were differentiated from affected animals by urinalysis and urine culture. The experiment was composed of sows with UTI that received the cranberry extract product in the diet for a period of 14 days; sows negative for UTI (negative controls) and sows positive for UTI (positive controls). The former two groups did not receive the cranberry extract product in the diet. Urine samples were collected on days zero, seven and 14 after initiation of treatment. Complete urinalysis of these samples, urine specific gravity, pH, bacterial count and bacterial isolation were performed. E. coli was the most frequent isolated agent (90.62%). The results showed that the commercial product made with cranberry extract was effective in promoting a reduction of urinary pH, but did not interfere in any other parameters observed.
