Abstract :

Perlite is among silicon volcanic stones and posses a neutral pH and had been admitted in thechemical direction of food. An experiment was conducted to study the effects of perlite onmorphology of villi in the small intestine of male broilers. The experimental design wasarranged as randomized complete bocks in 4 * 2 factorial arrangement of treatment. 120 malebroilers of Ross commercial hybrid (Ross 308) was designated into 2 groups (control andtreatment). 3 replicates of 20 birds were assigned to each treatment. Control treatments were fedbase 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% oftotal length the small intestine) were taken from each replicates (N=2). Morphology of villi wasmeasured and recorded. Data were analyzed by SAS (P<0.05).Results: As intake of perlite significantly changed in the morphological of villi at weeks andsites of the small intestine of the broiler chicks (P<0.05), these data suggested that perliteadministration improves fat digestion and absorption in broiler chicks.As morphological of villi is responsible for digestion and absorption in the small intestine and asthe effect of perlite administration in the diet of broilers on this morphological of villi had notbeen investigated the fallowing work had been designed and performed.
