Feed Additive Vegetable Oil, Addition to Commercial Feed on the Feed Efficiency and Fat Content of Red Tilapia (Oreochromis Niloticus)

This study aims to determine the effect of conventional vegetable oil as feed additive, according to soybean oil, coconut oil, corn oil, and the effect of feed efficiency, feed conversion ratio (FCR) and fat content of red tilapia. Feeding trial in this study had used Completely randomized design (CRD), with 4 treatments and repeated 4 times. Red tilapia as much as 160 used initial weight of 25-40g/head, kept in an aquarium with a volume of 20 dm3 with density 2 ind./L, and fed a pelleted with addition vegetable oil for 40 days. The results showed that there was a significant difference(p < 0.05) in Feed Efficiency (FE), and Feed Conversion Ratio (FCR). The highest EPP value in treatment addition soybean oil 4% was 66.06% (P < .05), and then treatment corn oil (47.28%), while the control treatment not addition of vegetable oil gave FE as much as 46.70%, and coconut oil was 39.60%. The best FCR value in treatment addition soybean oil 4% as much as 1.52 (P < 0.05%), while feed additive corn oil was 2.23, control was 2.17, and coconut oil was 2.27. Feeding with the addition of 4% soybean oil was the best treatment for growth, while the addition of coconut oil and corn oil increased the fat content of fish descriptively compared to without the addition of oil
