Online published on 13 November, 2019. Abstract Background Coccidiosis is a parasitic disease that disrupts digestive tract, especially in caecum. It causes a lot of harm to chicken farms. Formalin, can be a new invention as an alternative for Eimeria tanella protozoa attenuation in vaccines. Aim To determine formalin effect and optimum concentration for formalin attenuation of pathogenicity to cecum lesions inoculated score in boiler chickens. Method This study was an experimental study using completely randomized design (CRD) with five treatments. Treatment variation is formaldehyde with a concentration of 0%, 0.15%, 0.3%, 0.6%, 1.2% Results Results of the study showed that formalin with different concentrations resulted in a significant decrease. Decreasing microscopic cecum lesions inoculated score in boiler chickens in each treatment 0%, 0.15%, 0.3%, 0.6% and 1.2% were 10.32; 9.86; 7.00; 5, 14; 4.98 respectively. The largest decrease in lesion score was at 1.2%. Conclusion Formalin with 1.2% concentration could reduce cecum lesions inoculated score in boiler chickens Top Keywords Formalin, E. tenella, Caecum of boiler chicken, Attenuation. Top |
