Variance Components for Test-Day Milk, Fat, and Protein Yield, and Somatic Cell Score for Analyzing Management Information
The objective of this study was to estimate variance components for TD milk, fat, and protein yield, and SCS by using a random regression TD model. Special focus is given to HCUR and HTD variances, which are mainly related to between- and within-herd management.
Body Condition Assessment Using Digital Images
The purpose of this project was to assess the utility of using digital or video images to evaluate the BCS of a group of cows. Our second aim was to construct a model to determine the sample size needed to estimate the mean BCS of
a group of dairy cows.
