The Use of Dietary Mint Leaves Powder (Mentha piperita) as a Phytobiotic on Intestinal Histomorphology of Broiler Chickens

This study aimed to determine the effect of dietary mint leaves powder on the intestinal histomorphology of broiler chicken. The materials used in this study were 200 one-day-old male broiler chickens (Lohmann strain) that were kept for 35 days. The method used was an experiment using a completely randomized design with five treatments and five replications (each replication consisted of 8 birds). The treatments used were Control: basal diet without feed additive, AGP: basal diet + 0.01% zinc bacitracin, MLP0.5: basal diet + 0.5% mint leaves powder, MLP1.0: basal diet + 1% mint leaves powder, and MLP1.5: basal diet + 1.5% mint leaves powder. The variables observed in this study were villous height, basal villous width, apical villous width, villous number, villous surface area, and crypt depth. The results showed that the administration of peppermint leaves powder could increase apical villous width (P<0.05) and villous number (P<0.01). However, the treatments did not affect (P>0.05) on villous height, basal villous width, crypt depth, and villous surface area. It could be conclu
