Pakan Aditif Ekstrak Etanol Lumut Hati Meningkatkan Pertumbuhan Morfologi Duodenum dan Perkembangan Otot Dada Ayam Pedaging (SUPPLEMENTATION OF ETHANOLIC EXTRACT OF MARCHANTIA IN PRE-STARTER DIET IMPROVES THE GROWTH OF DUODENUM AND PECTORALIS THORACICUS

This study aimed to determine the effectiveness of ethanolic extract of Marchantia as an alternative additive in broiler’s chicken feed. The research was designed by using 5 treatment groups with 20 day-old chick broilers in each group and the treatment was done until the sample aged 14 days. The treatment groups consisted of basal feed and ethanolic extract of Marchantia in 0; 62.5; 250; 500; 1000 mg/kg basal feed. Data were analyzed by using one way ANOVA test followed by Tukey test with significance P<0.05. The results showed that at 14 days old of the sample, the weight gain of the broilers in the treatment group 1, 2, 3, and 4 were higher than the control group; Feed Conversion Ratio of treatment group 4 was better than the control group and other treatments; the small intestine morphology of villus heights, crypt depth, and villus/crypt ratio showed that the treatment group 3 and 4 were better than the control group; the pectoralis muscle’s weight, muscle’s area, and myofiber’s area showed that the treatment group 1 and 3 were better than the control group. The study indicates that the ethanolic extract of Marchantia spp. with concentration of 750-1000 mg/kg basal feed has effective ability as an alternative additive in broiler’s chicken feed.
