Effectiveness of enrofloxacin-alginate gel to prevent newborn calves’ navels infection
Abstract A trial was conducted with 414 newborn calves randomly divided by riskblocks of developing omphalitis or omphalophlebitis: low; medium, and high. The treatments were applied by stump-dipping daily for three days, with either iodine-polyvinylpyrrolidone (I-PVP) (n = 205), or with an alginate gel containing 0.5 % enrofloxacin hydrochloride dehydrate (enro-C) (n = 209). Results showed that only one death occurred in the enro-C group, which was attributable to internal hemorrhage not linked with the treatment. After four days, we recorded six other cases as stump fibrosis, but these were inconsequential. In the I-PVP group, 44 calves developed cord infection and were considered treatment failures (13 high-risk; 11 medium-risk, and 20 low-risk) (P < 0.0435 in the three risk grades). The umbilical stump involution was evident in the enro-C-treated animals on day one as most stumps were noticeably dried. Stump detachment occurred within an average of nearly 30 days, and the umbilical scars did not present infection in any case. Conversely, in the remaining calves of the I-PVP group, stump drying was observable after 72 h, and it detached within an average of 32 days (P < 0.05). In stumps treated with enro-C, dirt stuck less, and the gel formed an apparently protecting layer around the umbilical scar when stump was either absent or too short. These results show that enro-C is a successful preventive treatment that allows rapid umbilical stump involution in newborn calves.
