The Effect of Different level of Probiotic Addition on Commercial Feed against Digestibility and Efficiency of Nile Tilapia Feed (Oreochromis Niloticus)

Abstract

Tilapia cultivation is intensively developed by relying on commercial feed to increase production. This has led to an increase in production costs in tilapia cultivation. One effort to improve feed efficiency is by adding probiotics. The working mechanism of probiotic bacteria increases the value of feed digestibility. This enables fishes to optimally absorb feed nutrients which results in the increasing value of feed efficiency and reduce in production costs. The research was conducted on March 19 to April 21, 2018 at Balai Ikan Ikan Kabat, Banyuwangi. The design used in this study was a completely randomized design with 4 treatments and 5 replications. The results of the study indicated that the addition of probiotics to commercial feed was able to show significant differences (p<0.05) on protein and fat digestibility, but did not show significant differences (p> 0.05) on the value of tilapia fish feed efficiency.
