Abstract

Energy is a feed ingredient that has an important role in terms of chicken growth in addition to protein. Oil as an energy source that is often used is less efficient because oil is difficult to digest. So, in this study, a trial was conducted to add a bio-emulsifier from the bacterium Pseudomonas putida as a feed additive to the performance of broiler chickens. This research was conducted using 2 methods, namely the in vitro method and the in vivo method. In vitro tests were conducted to test the formation of oil bubbles in water using a bio-emulsifier, while in vivo tests were carried out on 200 Cobb strain broiler chickens aged 2135 days which were divided into 4 treatments using 5 replications each using 10 chickens. The feed treatments tested were based on doses of 0, 0.5, 1, 1.5 g/kg of feed. The treatments consisted of P0 = control feed, P1 = feed with the addition of a bio-emulsifier from Pseodomonas putida 0.5 g/kg feed, P2 = feed with the addition of a bio-emulsifier from Pseudomonas putida 1 g/kg feed, P3 = feed with the addition of bio - emulsifier of Pseudomonas putida 1.5 g/kg feed. Parameters observed were feed consumption, body weight gain, and feed conversion. In the first trial it was found that the bio-emulsifier could increase the formation of small oil bubbles in water, while the second trial showed that body weight gain, feed consumption, and feed conversion were not affected by the bio-emulsifier supplementation given, but the results did not decrease broiler performance. itself. This results give new information that bio-emulsifier from Pseudomonas putida could potentially as new alternative feed additive in the future in broiler performance.
