Sericea lespedeza has no anticoccidial effect when included in the diet of chickens infected with three species of Eimeria
چکیده انگلیسی

Anticoccidial effects of Sericea Lespedeza (SL) included in the diet at different levels were evaluated in chickens following oral infection with sporulated oocysts of either Eimeria acervulina, Eimeria maxima or Eimeria tenella. A series of experiments were conducted to determine the effect of SL upon the ability of the parasites to multiply in the intestine, and the effect on bodyweight gain, feed intake, and feed conversion following infection. Chicks infected with a low dose of oocysts (500 oocysts/bird) of E. acervulina or E. maxima did not show differences in the numbers of oocysts produced in the feces whether they were given 0, 1, 2, or 4% SL in the diet. There was no significant difference in the weight gain, feed intake, or FCR of birds infected with high doses of E. acervulina or E. maxima (200,000 or 100,000 oocysts/bird respectively) whether 0, 1, 2, or 4% SL was included in the feed. No significant difference in the numbers of oocysts in the feces, weight gain, feed intake, and FCR of birds infected with E. tenella (low dose of 500 oocysts; high dose of 50,000 oocysts per bird) whether 4% SL was included in the feed. The results of this study indicate that SL has no anticoccidial activity against Eimeria species in the chicken.
