THE EFFECT OF Lactobacillus salivarius I-11 ON MICROBIAL POPULATIONS OF PELLET DUCK FEED

摘要

An in vitro study was performed with the aim to evaluate addition Lactobacillus salivarius I-11 on population bacteria of pellet duck feed. The completely randomized design was been used on this research with 3 treaments and 3 replications with 5 experimental units. The treatments were P0 (Pellet feed duckwithout addition), P1 (Pellet feed duck with 2% addition Lactobacillus salivarius I-11) and P2 (Pellet feed duck with 4% addition Lactobacillus salivarius I-11). The parameters were total lactic acid bacteria, total bacteria, total fungi, and Coliform bacteria. The data obtained were analyzed variance (ANOVA) and further tests performed Duncan's Multiple Areas. The population of lactic acid bacteria was higher (P<0.05) and the total bacteria, fungi and Coliform were lower (P<0.05) with addition Lactobacillus salivarius I-11. The conclusion was addition of Lactobacillus salivarius I-11 as probiotics affects the lactic acid bacteria in pellet duck feed significantly (p<0.05) increased but decreased the counts of total bacteria, total fungi and Coliform.
