DHI report is an important tool for dairy farm management, in which MUN and WHI are two key indicators. MUN (urea nitrogen in milk) reflects the protein metabolism of dairy cows. A high level of MUN may mean an excessive amount of protein in dairy cow feed, which may have a negative impact on the health and productivity of dairy cows.
WHI (intra-group level index) is an index to evaluate the genetic quality of dairy cows, which comprehensively considers many factors such as the yield, body shape and health status of dairy cows, and helps ranchers to understand the overall performance of their cows.
