Johnson & Reid Coccidiosis Lesion & Intestinal Integrity Scorecard

Calculate Intestinal Integrity Index (IIC) from necropsy lesion scores (E. acervulina, E. maxima, E. tenella) to optimize anticoccidial programs.

🔬 Scientific Disclosure: Intestinal Integrity Index (IIC) Formula

IIC = 100 - (Mean_Upper_Gut * 6.25 + Mean_Mid_Gut * 8.75 + Mean_Cecal * 10.0)

Johnson & Reid (1970) necropsy scoring quantifies subclinical Eimeria infection severity to prevent FCR degradation.
