Finishing cattle at grass on the Thrive demo farm last autumn. It is often said that there is as much variation within a breed as there is across breeds, and looking at the production data from the Thrive demonstration farm for the 2019-born stock, this certainly holds true. We must remember that this is a relatively small sample size and therefore we must be careful with any extrapolation of the data to a national scale. However, there are some positive outcomes from this dataset. The first and most important of these is a positive correlation between the DBI, value of beef and the carcase weight achieved by the animal.
