New spreadsheet helps track heifer growth

A new growth spreadsheet that generates a customized growth curve for an individual herd based on that herd’s goal for age at first calving and other factors is now available.

Using this tool, you will be able to tell at every step of the way whether heifers are on track to calve at the right size and age, eliminating the delay that comes with not measuring heifer performance until first calving.

“If we know the mature size of a heifer and her current size, it is a relatively simple matter to figure out what growth rate we need to achieve to move from the current size to the mature size, or to benchmark times in between, such as breeding,” say researchers at Penn State University.

“We have developed a new growth tracking spreadsheet that automates these calculations and can generate a customized growth curve for an individual herd based on that herd’s goal for age at first calving and the mature size of animals in the herd.”

Users can plot growth data from heifers on these graphs to compare individual heifer performance to the goals.
