In a randomized complete-block design with 4 blocks and 4 treatments, 112 day-old male broiler chicks were divided into 16 groups, 7 chicks per. Treatments consisted of three levels of AFB1 in starter diet (0.4, 0.8, and 1.2 ppm) along with a control group (no AFB1). Feed intake and body weight gain were recorded on a weekly basis. On days 7, 14, 21, and 28, one bird from each replicate was weighed, and killed to collect the blood samples, and to weigh its proventriculus, gizzard, duodenum and pancreas, heart, liver, spleen, bursa of fabricius, and brain. Feeding AFB1 significantly decreased feed intake and body weight gain and increased relative weight of liver (p CP - IRAN IN - LG - eng PB - JSTNAR PG - 443 PT - Research YR - 2007
