Effects of perlite on morphology of villi in the small intestine of broiler chicks

Perlite is among silicon volcanic stones and posses a neutral pH and had been admitted in the chemical direction of food. An experiment was conducted to study the effects of perlite on morphology of villi in the small intestine of male broilers. The experimental design was arranged as randomized complete bocks in 4 * 2 factorial arrangement of treatment. 120 male broilers of Ross commercial hybrid (Ross 308) was designated into 2 groups (control and treatment). 3 replicates of 20 birds were assigned to each treatment. Control treatments were fed base diet and treatment with the same base diet plus 2% perlite. Animals were slaughtered and different segments of small intestine(at1,10,30,50,70 and 90% of total length the small intestine) were taken from each replicates (N=2). Morphology of villi was measured and recorded. Data were analyzed by SAS (P
