[Examination of a novel wax teat bougie for treatment of wounds in the papillary lactiferous sinus of dairy cows with special regard to endoscopic documentation of mucosal reactions compared with conventional teat bougies and a teat cannula].
The present study on a novel wax-teat bougie, developed by Dr. T. GEISHAUSER for treatment of wounds in the papillary lactiferous sinus of dairy cows, has been performed in two phases of investigation. In a first step, fourteen healthy dairy cows (Deutsch Schwarzbunt) in state of early lactation were dried off temporarily for five days, after checking milk samples of all quarters for six following-on days on their bacteriological status, number of somatic cells, conductivity and results of the California-Mastitis-Test (CMT). The drying off was performed on two Quarters with similar cell-count in milk samples each. In one teat of the selected pairs off udder quarters, the wax-bougie was applied (group I), the other corresponding udder quarters were used as a control (group II). After five days of drying off, lactation was started again after removing the bougies in treated quarters. For another five days milk samples out of the quarters in groups I and II were checked in the laboratory tests named above and mean values and increase differences of results were compared. Comparison of increase differences with t-test showed no statistically significant difference between drying off procedures with the wax-bougie and without any treatment in the parameters named above. Courses of counts of somatic cells, conductivity and CMT showed no significant differences between drying off probands by using the novel wax-bougie and drying off without further treatment. In the second phase of the study, fifteen lactating, healthy dairy cows as probands have been split in five groups. Three cows (twelve udder quarters) were dried off for five days by using the novel teat bougie (group D), in three groups (A,B,C) two different types of conventional teat bougies and one type of cannula were used, and, as a control three cows (group E) were dried off without any treatment. Before drying off the udder quarters and after starting lactation again, the condition of the mucosa in the teat papillary lactiferous sinus has been documented by means of endoscopy and the bacteriological status of milk samples has been determined. As a result all udder quarters dried off temporarily showed endoscopically detectable inflammatory-proliferating reactions in the mucosa of the papillary lactiferous sinus, whereas in cows treated with the novel wax-bougie (group D), as well as in the cows of the control group (E), there were no inflammatory reactions detectable at all. These different reactions, basing on the Fisher-test, have to be considered statistically significant (p < 0.001).
