The new definition of a lamb comes in from the 1st July 2019. Essentially the change will extend the period a lamb is still a lamb by around 4 weeks. The definition changes from “…..has 0 permanent incisor teeth” to “…..does not have any permanent incisor teeth in wear”. Research (Wiese et al. 2005) has shown this additional short period of time a lamb is still considered a lamb will have “no discernible difference in eating quality”.
