Ultrasound of dairy cows' udder: Echotexture, milk vein blood flow, somatic cell count and milk yield
Description
This dataset contains supplemental material to the research article: "Udder ultrasonography of dairy cows: Investigating the relationship between echotexture, blood flow, somatic cell count and milk yield during dry period and lactation". Dataset contents explained: - An avi. video file presenting a color Doppler ultrasonographic examination of the blood flow in the milk vein of a cow - Table 5: Echotexture parameters stratified by production stage (late lactation, dry period, early lactation) and lactation period (1st lactation referred to as “heifers” / ≥2nd lactation as “cows”) - Table 6 (Sensitivity analysis): Association between blood flow volume and udder echotexture features using linear mixed models with random effects, using B-mode image 1 - Table 7 (Sensitivity analysis): Association between blood flow volume and udder echotexture features using linear mixed models with random effects, using B-mode image 2 - Figure 6: Changes in 9/15 echotexture features (A–I), the rest of the ones presented in Figure 4 of the research article, throughout the period of the study: from 7 days before the dry period (DP), at dry-off and dur-ing the DP, 7 and 3 days prior to calving, at calving (C) and from the 3rd to 90th DIM in the sequent lactation - Figure 7: Proportion of animals with SCC>200,000 cells/mL in 0, 1, 2, 3 or 4 udder quarters per measurement day - Figure 8: Estimated daily milk yield of the animals in the study with SCC>200,000 cells/mL in 0, 1, 2, 3 or 4 udder quarters, according to our multivariate model presented in the research article
