Probiotik merupakan mikroorganisme hidup yang berperan dalam mendukung pertumbuhan unggas dan meningkatkan kesehatan saluran pencernaan. Penelitian ini bertujuan untuk mengetahui efektivitas probiotik dalam bentuk minuman fermentasi dan Aspergillus niger untuk meningkatkan produktivitas ayam broiler, memperbaiki kesehatan saluran pencernaan, serta mengurangi residu antibiotik pada daging. Penelitian ini dilaksanakan di LLP (Laboratorium Lapangan Peternakan) Universitas Syiah Kuala, pengamatan gambaran histologis permukaan vili usus ayam dilaksanakan di Laboratorium Struktur dan Perkembangan Hewan serta pengujian residu antibiotik dilakukan di laboratorium Mikrobiologi FMIPA Universitas Syiah Kuala. Metode yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan (Air minum (kontrol), Antibiotik, Kefir 5%, Yakult 5 %, Aspergillus niger 2 %) dan 3 kali pengulangan. Hewan uji yang digunakan ialah ayam broiler DOC- Dewasa (Panen) dengan berat awal rata rata 51-57 gram sebanyak 75 individu yang dipelihara selama 4 minggu (30 hari). Parameter yang diukur meliputi performa (pertambahan bobot badan, konsumsi pakan, konsumsi air, konversi pakan dan efisiensi pakan), gambaran histologis vili usus (tinggi, lebar apikal, lebar basal, dan luas area total), serta residu antibiotik pada daging. Data dianalisis dengan menggunakan uji ANOVA dengan taraf signifikansi 95% dan diuji lanjut dengan multiple range test Duncan (P

Probiotics are living microorganisms that play a role in supporting poultry growth and improving digestive tract health. This study aims to determine the effectiveness of probiotics in the form of fermented drinks and Aspergillus niger to increase broiler chicken productivity, improve digestive tract health, and reduce antibiotic residues in meat. This study was conducted at the LLP (Livestock Field Laboratory) of Syiah Kuala University, histological observations of the surface of the chicken intestinal villi were carried out in the Animal Structure and Development Laboratory and antibiotic residue testing was carried out in the Microbiology Laboratory of the Faculty of Mathematics and Natural Sciences, Syiah Kuala University. The method used in this study was a Completely Randomized Design (CRD) with 5 treatments (Drinking water (control), Antibiotics, 5% Kefir, 5% Yakult, 2% Aspergillus niger) with 3 repetitions. The test animals used were DOC-Adult broiler chickens (Harvest) with an average initial weight of 51-57 grams as many as 75 individuals kept for 4 weeks (30 days). Parameters measured included performance (weight gain, feed consumption, water consumption, and feed conversion), histomorphometry of intestinal villi (height, apical width, basal width, and total area), and antibiotic residues in meat. Data were analyzed using ANOVA with a significance level of 95% and further tested with Duncan's multiple range test (P
