The CG36 is #1 in the industry for a quality underline. Underline counts can range from 16 to 22 functional teats. With a quality underline like that, the CG36 has the potential to successfully nurse 13 to 15 piglets/litter. As with all female lines, as the CG36 ages, reaching the 4th or 5th parity, her potential lessens to weaning 11 to 13 piglets/litter.
