Penelitian ini bertujuan untuk mengetahui pengaruh bakteri asam laktat (BAL) asal saluran pencernaan itik lokal Aceh terhadap performan itik hibrida jantan. Penelitian ini menggunakan 60 ekor itik hibrida putih jantan. Bakteri asam laktat diberikan pada itik jantan secara oral dengan jenis bakteri Lactobacillus fermentum dan Pediococccus acidilactici. Itik hibrida jantan ditempatkan secara acak ke dalam empat perlakuan. Empat perlakuan meliputi K: tanpa antibiotik dan bakteri asam laktat (kontrol negatif); BA0: antibiotik Zinc Bacitracin 40 mg/kg pakan (kontrol positif); BP106: penambahan Pediococcus acidilactis 106 CFU/ml/ekor/hari dan BL106: penambahan Lactobacillus fermentum 106 CFU/ml/ekor/hari. Setiap perlakuan terdiri dari 3 ulangan dan setiap ulangan terdiri dari 5 ekor itik. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) selama 28 hari. Data yang diperoleh meliputi konsumsi pakan, pertambahan bobot badan, dan rasio konversi pakan dianalisis dengan analisis varians (ANOVA) dan data yang berbeda nyata antar perlakuan dilakukan uji lebih lanjut menggunakan Duncan's New Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa penambahan bakteri asam laktat (BP106 dan BL106) dan Zinc Bacitracin (BA0) dalam ransum dapat meningkatkan bobot badan dan menurunkan rasio konversi pakan (P<0,05), tetapi tidak berpengaruh nyata terhadap peningkatan konsumsi pakan. Adapun hasil penelitian dapat disimpulkan bahwa penambahan bakteri asam laktat dari saluran pencernaan itik lokal Aceh dapat meningkatkan performa itik hibrida jantan.

The objective of this study was to investigate the effect of lactic acid bacteria (LAB) of local Aceh ducks digestive track to male hybrid duck performance. This study used 60 male white hybrid ducks. Lactic acid bacteria were given to male ducks orally with the types of bacteria Lactobacillus fermentum and Pediococccus acidilactici. Male hybrid ducks were placed randomly into four treatments. Four experimental diets include K: without antibiotics and lactic acid bacteria (negative control); BA0: Bacitracin antibiotic 40 mg/kg of feed (positive control); BP106: the addition of Pediococcus acidilactis 106 CFU/ml/bird/day and BL106: the addition of Lactobacillus fermentum 106 CFU/ml/bird/day. Each treatment consisted of 3 replications and each replication consisted of 5 ducks. This research was conducted using completely randomized design (CRD) for 28 days. Obtained data included feed intake, body weight gain, and feed conversion ratio were analyzed by analysis of variance (ANOVA) and the mean values wich were significant different were further tested using Duncan's New Multiple Range Test (DMRT). The results showed that the addition of lactic acid bacteria (BP106 and BL106) and Zinc Bacitracin (BA0) in diets significantly ncreased the body weight and reduce feed conversion ratio (P<0,05), but it had no significant effect to increase feed intake. As the results of the study can be concluded that the addition of lactic acid bacteria from the digestive tract of local Aceh ducks can improve the performance of male hybrid ducks.
