Abstract
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.

Summary
Daging ayam merupakan salah satu bahan makanan yang diminati oleh masyarakat karena menjadi sumber pemenuhan kebutuhan gizi bagi masyarakat khususnya terhadap protein hewani. Salah satu bagian penting dalam menunjang ketersediaan daging dan kualitas daging ayam pedaging tersebut adalah penyediaan pakan yang baik. Salah satu cara yang digunakan untuk meningkatkan performans ayam ternak adalah dengan menambahkan zat aditif pada pakan yang diberikan. Zat aditif tersebut tentunya harus dapat diserap dengan baik oleh ayam yang diternakkan. Berbagai penelitian telah banyak dilakukan untuk menelusuri adanya komponen senyawa bioaktif yang dimiliki oleh tumbuhan dan aman digunakan sebagai zat aditif pada pakan ternak. Aplikasi senyawa tersebut pada berbagai bidang, seperti sebagai bahan aditif pada pakan ternak ayam, masih memerlukan kajian lebih lanjut. Berdasarkan latar belakang tersebut, maka tujuan penelitian ini adalah mengkaji pemanfaatan ekstrak lumut hati (Marchantia spp.) sebagai kandidat pemilik senyawa bahan aditif pakan ternak guna meningkatkan performans ayam pedaging
