In swine ear notching, what does a notch on the right ear represent?

In swine ear notching, a notch in the right ear represents the litter number of the pig. This system is an effective way for producers to identify individual pigs based on their litters, which is vital for tracking lineage, breeding programs, and overall herd management. Each notch in the right ear corresponds to a specific litter, allowing producers to easily discern from which group a particular pig originates. This identification method is essential for record-keeping and ensuring good breeding practices, as it helps in monitoring the health and productivity of different litters over time.
