Abstract
Penelitian ini merupakan studi kasus yang bertujuan mengevaluasi pemanfaatan probiotik cair berbasis Lactobacillus sp., Bacillus sp.1, dan Bacillus sp.2 sebagai alternatif non-Antibiotic Growth Promoters (AGP) pada produksi ayam broiler di Peternakan Ali Farm 1 dan Ali Farm 2, Kabupaten Sukabumi. Penelitian dilakukan menggunakan studi implementasi lapang dengan pendekatan observasional komparatif selama 32 hari, terdiri atas kelompok tanpa probiotik (P0) dan kelompok dengan suplementasi probiotik cair dosis 3 ml/L air minum (P1). Parameter yang diamati meliputi bobot badan akhir, konsumsi pakan, Feed Conversion Ratio (FCR), uniformity, dan mortalitas. Hasil menunjukkan bahwa pemberian probiotik meningkatkan bobot badan akhir, menurunkan FCR dan konsumsi pakan, meningkatkan uniformity, serta menurunkan mortalitas. Probiotik cair berpotensi digunakan sebagai alternatif non-AGP dalam produksi ayam broiler.
