Supplementary material and Dataset for the study Complex relations between milking-induced changes in teat structures and their pre-milking dimensions in Holstein cows

Over the past decades, multiple studies have investigated the relation of teat morphology to udder health and milkability. Nevertheless, it is essential to examine how dimensions of teat structures influence each other. The main study, which is linked to this supplementary file and dataset, aimed to explore the relations between the dimensions of teat structures and their short-term reaction to milking to find the ideal dimensions of teat structures for optimal response to milking. Teat structures (teat length, canal length, thickness at barrel and apex, wall, and cistern width) were measured by ultrasonography before and after milking for 38 Holstein cows at the beginning, middle, and end of lactation. The dataset includes the identification number of the cow, lactation number, date of measurement, days in milk for the day of measurement, and teat measurements (before milking, after milking, and relative milking-induced change). Additional information about the milking parlor settings and the cows in the experiment (milk yields, milk quality, reproduction, genetics) can be found in the second sheet of the dataset, where we provide an external link to the national database of cattle (Czech Republic). After putting the identification number of the cow into the text field found on the link, all available information will be loaded in Czech. However, we recommend using "translate website" tool in the browser for the English version. The dataset could be used for studies in the research area of teat and udder morphology.
The supplementary file contains additional statistics, supplementary results, and supplementary discussion for the manuscript "Complex relations between milking-induced changes in teat structures and their pre-milking dimensions in Holstein cows". This study's main findings and outcomes are presented in the main manuscript.
