Randomized controlled clinical trial on the effect of oral immunoglobulin supplementation on neonatal dairy calves with diarrhea

Chung, James J.; Rayburn, Maire C.; Chigerwe, Munashe

Fecal consistency of calves was monitored twice daily by the authors based on a fecal scoring system. 15 The volume of milk consumed by each calf at the 2 feeding times was estimated and recorded by the authors. Time (days) at which the fecal score was deemed normal based on the fecal scoring system was recorded. Decision to treat calves with diarrhea and the choice of medical treatments were performed by trained farm personnel, based on the farm's standard operating procedures designed by the attending licensed farm veterinarian. Records of all medical treatments including type of treatments, duration of treatment, and deaths were available to the authors through the electronic farm record system. The attending licensed farm veterinarian performed field necropsies on calves that died.
