Serum coloration as a criterion of the severity of experimental coccidiosis in the chicken.
Serum decoloration may be used as a criterion for the severity of coccidiosis. Direct measurement of serum coloration at 480 nm is easy to carry out and, with micromethods, it is not necessary to slaughter animals. With intestinal coccidia the sensitivity is high, and there is good correlation with the severity of infection and variability is small. With Eimeria tenella infection the criterion is less sensitive, but may be of value for some purposes.
