  Lipase is an enzyme responsible for digestion and absorption of lipids in the small intestine and effect of perlite in the diet of broilers on lipase enzyme had not been investigated. This study had been designed and performed to evaluate effect of different levels of perlite on lipase enzyme activity in small intestine of male broiler chicks. The experiment design was arranged as randomized complete bocks in 4 x 2 factorial arrangement of treatment. The 180 male broilers of Ross 308 commercial hybrid was designated into 3 groups (0, 2 and 4%). Three replicates of 20 birds were assigned to each treatment. Control treatments were fed base diet and treatment groups with the same base diet plus 2 or 4% perlite. Animals were slaughtered at 21, 28, 36 and 42 days and different segments of small intestine (at 1,10,30,50,70 and 90% of total length of the small intestine) were taken from each replicates (n=2). Lipase enzyme activity was measured and recorded. Data were analyzed by SAS (p<0.05). Data showed that intake of perlite, significantly increased Lipase enzyme activity at different weeks and sites of the small intestine of the broiler chicks (p<0.05). These data suggested that 2% perlite administration had significantly affected lipase activity as compared with control treatment.

  An experiment was conducted to study the effects of different levels of perlite on serum calcium, phosphor and chloride in broiler chicks. The experimental design was arranged as randomized complete blocks in 4x2 factorial arrangement of treatment. About 180 male broilers of Ross 308 commercial hybrid was designated into 3 groups (0, 2 and 4%). About 3 replicates of 20 birds were assigned to each treatment. Control treatments were fed base diet and treatments with the same base diet plus 2 and 4% perlite. The feeding continued up to the age of 42 days. At the 21 and 42 days, 6 birds from each treatment were selected for serum calcium, phosphor and chloride in broiler chicks. Blood samples were collected from the vena axillaries). As intake of perlite, significantly increased serum calcium, phosphor and chloride at weeks on broiler chicks (p<0.05) these data suggested that perlite administration did not have significant effect on control treatment comparing to treatment.
