Effect of Different Levels of Perlite on Sucrase Mucosal Enzymes Activity in Small Intestine of Broiler Chicks

Sucrase enzyme is an enzyme responsible for digestion and absorption of carbohydrates in the small intestine and as the effect of perlite administration in the diet of broilers on this enzyme had not been investigated the following study had been designed and performed. An experiment was conducted to study the effects of different levels of perlite on Sucrase enzyme activity of the small intestine in male broilers. The experimental design was arranged as randomized complete bocks in 4 x 2 factorial arrangement of treatment. 180 male broilers of Ross 308 commercial hybrid was designated into 3 groups (0, 2 and 4 %). 3 replicates of 20 birds were assigned to each treatment. Control treatments were fed base diet and groups with the same base diet plus 2 or 4% perlite. Animals were slaughtered after 21, 28, 36 and 42 days and different segments of small intestine (atl,10,30,50,70 and 90% of total length of the small intestine) were taken from each replicates (TST=2) Sucrase enzyme activity was measured and recorded. Data were analyzed by SAS (P<0.05). As intake of perlite, significantly increased Sucrase enzyme activity at weeks and sites of the small intestine of the broiler chicks (P<0.05). It was concluded that perlite administration has significant effect on Sucrase enzyme activity of the broiler chicks.
