Faster Horses,
It isn't always a nutrition thing. We get it the worst with older calves that have been thru some tough weather. They don't suck for a day or two and load up on milk when they find momma and bango they get enterotoxemia. Kills them very fast in not looking for it.
We give the C&D shot right after they are born when we tag anywhere from an hour of two after birth to a day later. Don't know if its right but works for us.
Well, it's still nutrition, if the calf doesn't suck and gets a big charge of milk, right?

Maybe you couldn't help the circumstances, but it was still nutrition or lack of for several hours.
We just fed grass hay and we had everything happen to us and more, that happened to everybody else that posts here. We eliminated overeating without giving shots. I'm not saying that works for everyone, but it was something that has worked for many. I just threw it out there as food for thought on what was being fed post-calving. We went through a horrendous 8 years of sick calves and I wouldn't wish that on anyone. We eliminated all our problems with good nutrition program and way less vaccinations. We quit vaccinating at branding except for blackleg, and of course that Vision 7 shot for blackleg also contains C&D. But we didn't give anything else and never noticed a difference. Our vet says the calves are too young at branding to utilize the vaccine for IBR, BVD, PI3, etc. so we stopped giving it til we preconditioned. BTW, he also says Alpha 7 and Vision 7 are the most effective blackleg/C&D brands to use.
I've learned sometimes you can look at the whole situation, not just one part, hence food for thought. I could give names of ranchers who cut the protein out of their feed post-calving and eliminated over-eating. In situations like Jody experiences, putting an old bale of hay, or even straw,
out for the cows really helps satisfy their dry-matter needs and cuts down
the amount of green grass they eat which in turns lowers milk production
which plays a big part in entertoxemia.
Maybe I'm too eager to help. Please excuse me.
