Abstract
This experiment was conducted to investigate the effects of phytobiotic and antifungal feed additives on the growth performance, blood parameters, intestinal morphology, and cecal microbiota activity of broiler chickens under aflatoxicosis challenge. A total of 250 one-day-old Ross 308 broiler chicks (mixed sex) were reared on the littered floor with a completely randomized design by five treatments and five replicates for 35 days. Treatments included positive control (without AFB1), negative control-AFB1 (1 ppm), negative control-phytobiotic (Entex, 0.5 kg/t), negative control-Mycofix Plus (0.5 kg/t), and negative control-phytobiotic + Mycofix Plus. Dietary phytogenic and toxin binder improved body weight gain and feed conversion ratio of broiler chickens (ppp<0.05). Dietary treatments had no significant effect on the cecal microbial population in broiler chickens. In conclusion, the present results indicated that phytobiotic and toxin binder supplement improved growth performance and intestinal morphology of broiler chickens exposed to AFB1 challenge.
