The Application of Probiotic to Increase Growth, Body Composition, and Feed Efficiency on Catfish ( Clarias sp.)

Abstract

For 45 days, research was conducted to evaluate the administration of probiotic Bacillus NP5 to increase growth, body composition, and feed efficiency on catfish (Clarias sp.). This research was carried out with 3 different treatment of Bacillus NP5 probiotic doses (0, 0.5 and 1% probiotic) and 3 replications. The result showed that the value of the daily growth rate significantly showed the highest value (P<0.05) in 1% probiotic (11.32%), followed by 0.5% probiotic (9.20%) and control (8.20%). The value of protein and lipid composition was significantly in 1% probiotic (14.24%, 5.49%, respectively) than the other treatment. The administration of probiotic Bacillus NP5 not affect to water quality of catfish.
