I have always fed my pigs twice a day until I tried feeding once a day with the last batch. I have to say I found no difference with the finished pigs as the ones fed twice a day. The pigs are still visited twice a day to check on there welfare and I know you will say then you might as well feed them while your there. What I would like to know has anyone had problems feeding once and are there any downsides to one feed a day.
