Supplementary Material: Dairy Cows Udder Echtotexture and Blood Flow in Dry Period and Lactation

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:

- Tables 5, 6, 7: Ingredients, chemical composition and nutritive value of the total mixed rations provided for the: 1) High Lactation , 2) Low Lactation , 3) and 4) Close-Up (dry period) groups.

- 15 tiff files, presenting the 15 Echotexture Parameters' changes throughout the study period: starting from 7 days before the dry period (“DP”), throughout the DP, 7 and 3 days prior to calving, at calving (“C”) and from the 3rd to the 90th day in the new lactation (“DIM”: days in milk). These echotexture parameters are:
- Skewness
- Entropy
- Mean Pixel Standard Deviation
- Run Percentage
- Correlation
- Runlength Distribution
- Mean Numerical Pixel Value
- Contrast
- Percentage Non Zero Gradients
- Excess
- Gradient Mean Value
- Gradient Variance
- Grey Value Distribution
- Long Run Emphasis
- Homogeneity

- An avi. video file presenting a color Doppler ultrasonographic examination of the blood flow in the milk vein of a cow
