You can pan feed them milk and oatmeal if you add a little maple syrup they take to it faster. I raised mini pigs for years and offen had to pan feed in wet or cold weather.
Heat is the life blood to piglets, hopefully they took to their mom. I have my farrowing stall made out of pallets so the piglets can go through the slots in the pallets to the heat lamp after the nurse. Generally once they are 48hrs old they will be fine and make enough noise so the mom doesn’t hurt them. Sometimes a small litter isn’t a bad thing with a first time mom. Great job on getting them back up and going hopefully they all made it and are doing well.
so cute! Hopefully things all work out in the end, they do look so much better. Last year we had a baby goat that I swear just wanted to give up and die it took hours to get him on his feet and warm but he finally did pull through.
