I was using Sustain III. Seemed to work OK as long as you caught them early.
I recently switched to an injectable antibiotic, and they usually bounce back in a couple hours, but them sometimes relapse...
Are you vaccinating your cow herd? it takes a good vaccination program, a good feeding program and a mineral built for YOUR operation with Rumensin ( coccidiostat ) and Bio Moss mixed in to make the difference you want to see.
We still get scours but they are treatable. I have gotten good enough at spotting them I know the calf is sick before it does. That takes far more practice doctoring than I care to do again. Last year they were far less than ever and this year is better yet.
Rule of thumb here for antibiotics is under 10 days they are treated with Trimidox (Borgal) and over 10 days Liquamycin LA. Most respond immediately if they are caught soon enough.
Other drugs come into play if they persist.
To answer your question..... Yes, IV will save many of those calves that can't digest what you are giving them orally. It takes a lot of practice, frustration and perseverance to become proficient at picking up the jugular with an IV catheter but the percentage of live calves as a reward is greater.
