I have always used romaine lettuce with my piggies without any problems, a leaf every other day. I dont mean to sound stupid but what types of lettuce is meant by red and green leaf lettuce? There is a limited stock at my super market you see and it would be helpful if i know what i needed to switch to.
Many thanks in advance.

Romaine causes some pigs to excrete excess urinary calcium, but others are not bothered by it. If it bothers your pigs, try another kind.
But, your current pigs may continue to excrete it no matter what they eat. Some pigs are just prone to it, and you can't make enough dietary changes to keep them from it.
