Biguanide polymeric infusion in the uterine bacterial contamination of cows with puerperal infection after placental retention

Abstract

This study was carried out with the aim to verify the utilization viability of polymeric
biguanide solutions for the topic treatment of puerperal uterine infections in bovine females after
premature parturition. Twenty Girolando cows of a dairy farm, with placenta retention and metritis
were randomly distributed in two groups. Group 1, constituted of cows that received three uterine
infusions of a polymeric biguanide solution, and Group 2, with animals that were not submitted to
any treatment. There were taken uterine content samples at the first, third and fifth post partum
weeks for bacteriological cultures, that means, before the first infusion, 14 and 28 days after treatment.
The founds of bacteriological cultures in the two groups demonstrated that the solution of polymeric
biguanide was not effective to reduce uterine bacteriological colonization in cows with post partum
infections.
