Hi, two of five pigs we bought in three weeks ago (they are about 13 weeks old now) have died. The first one, the smallest died two weeks ago - we were away but the person looking after them said he was breathing fast in the morning and was dead when he came back later. It was an extremely hot weekend so we thought being the runt he might have struggled to cool down and died from the heat. Now the second smallest seemed to be breathing quicker than the rest two days ago. Was still eating but a lot smaller than the others but have found him dead this morning. The other two in the run are big and healthy and eating well. The third remaining pig is on box rest as about 10 days ago he came out of his house struggling to walk behind. He got better during the day and we were advised to put him on box rest. He has improved and can now stand on one back leg to scratch his belly but still looks a bit wobbly behind so don't want to put him in with the other two yet. (They were running about like loonys before he started having walking problems). DOnt think his problem is related to the dead ones though. Am trying to contact the person we contacted them from to find out if they have been wormed as I have read that some worms can cause Pneumonia. Anybody experienced similar? Any advice greatly appreciated. Thanks for reading, Katie.
