We started using Impro-Tec-500 in 2008 because we were losing newborn calves to a high mortality rate. Calves were dying within 48 hours of birth. Since using Impro-Tec-500 to our calves for the first 2-4 feedings, mortality rate has dramically dropped to almost zero. I would recommend anyone to give this product a try.
