Now feeding milk replacer does have something to do with causing the calf poop to smell horrible and a factor in treating the problem. You want to get this corrected right away. Poor nutritional absorption in calf will cause weakness and the organs to start shutting down quickly in a calf. Also weaken the immune system make the calf susceptible to a deadly rapid bacterial growth causing sudden death. Example: Blackleg
What is causing the poop is smell so bad
The calf's intestines are infected by a bacteria causing damage and poor nutritional absorption. E coli is common but also one of many bacteria that could be the problem.
How do I get my calf's intestines healthy again
Active charcoal or charcoal can help in most cases. But the problem is if you administer antibiotics you going to low the effectiveness of the antibiotics.
I use a two step treatment method that has worked extremely well for my calves. The first part is to give antibiotics and the next is to substitute milk replacer feeding with a different product for a few days. It is also important not to allow them water during this treatment time.
In my guidelines for raising and caring for calves the treatment use for scouring calves is the exact same treatment.
