Toxicological interactions of Abrus precatorius and Cassia senna in the diet of Lohmann broiler chicks.

The combination of 0.5% Abrus precatorius seed and 2% Cassia senna fruit in the diet of Lohmann broiler chicks caused severe lesions, reduced weight gain, inefficient feed utilization and anemia. Organ lesions correlated with changes in clinical chemistry and hematology. Tissue recovery was not complete 2 w following withdrawal of the test diet. Feeding 0.5% Abrus or 2% Senna diets alone produced decreased growth and tissue lesions that did not return to normal 2 w following return to normal rations.
