Had trouble this week with a group of calves. Start groups of 80 on bottles. This group was started in March, have not had any respiratory issues what so ever. Lost the usual couple in the first week or 10 days to scours. Have only treated one maybe 2 since weaning and none in at least 4 months. I give inforce on arrival, then inforce and once pmh nasal a week before weaning. They then had bovi gold, vision 7, endovac, and poured at about 450# about 30 days ago. Never even backed off feed after first round. I decided to add the once pmh nasal on the second round of shots a week ago, due to some struggles with respiratory issues on the last group a few weeks after moving to the finishing barn. The calves weigh about 600# now. After the second round of shots which included the bovi gold, endovac, vision 7 and once pmh nasal, 2 calves dead. Treated as soon as they looked off but nothing turned them around. What do you think caused it. TIA
Edit to add: these are beef cross calves. Vet says we should have been fine with 3 gram negative vaccines on them, only 2 on Holsteins. Although we are at the limit of 3.
