Mammary gland, spinning, California Mastitis TestResumo
Part of the mammary gland microbial infections are imperceptible to the milker. The prevention through hygienic-sanitary measures is thought as an efficient strategy to avoid mastitis. Evaluating whether the adoption of pre-dipping and post-dipping hygienic managements have significant effects with the use of the black background mug and California Mastitis Tests, individualized by post-dipping. The properties have the same breed, similar food management and common location, both in the rural area of Teresina. The only difference between them is the performance or not of the handlings that include pre-dipping and post-dipping. So, performing the minimum protocols or not caused the treatments to have a completely randomized delineation. Statistical analysis was obtained through the use of the packages “dplyr”, “rstatix” and “ggplot2”, available in Software R (2022). The compliance verification of the least squares method in relation to the normal distribution of data was performed through the Shapiro Wilk test, using the “byf.shapiro” procedure of the “RVAdeMemoire” package. Data did not present normal or Gausean distribution, so non-parametric statistics were resorted. To discriminate the difference, the post-hoc test by Dunn's test with p-value adjustment by Bomferroni's method. It was noted that the right rear teat presented milk without changes in lumps, color, and others in farm “A”, that the pre-dipping and post-dipping were performed.
