PENGARUH ENKAPSULASI MINYAK IKAN LEMURU DALAM RANSUM BERBASIS LUMPUR SAWIT FERMENTASI DAN EKSTRAK DAUN KATUK TERHADAP PERFORMA AYAM RAS PETELUR

This study aimed to evaluate the effect of using lemuru fish oil encapsulation ( EML ) in feed based on oil sludge fermentation (LSF) and extract of katuk leaves (EDK) on the
performance of laying hens. This study used 40 laying hens that has production in 7 months , divided into 4 treatments with 10 replications and each replication containing 1 laying hen which placed randomly on the battery cage system . Treatment consists of P0 ( feed without LSF , EDK and EML ) , P1 ( feed with 15 % LSF , EDK 0.6 % , 2.5% EML ) , P2 ( feed with 15 % LSF , EDK 0.6 % , 5 , 0 % EML ) and P3 ( feed with 15 % LSF , EDK 0.6 % , 7.5 % EML ). The results showed that encapsulation of lemuru fish oil in feed based on oil sludge fermentation and extract of katuk leaves were significantly (P < 0.05 ) on feed consumption , feed conversion and feed efficiency , but the effect were not significant ( P > 0.05) on the percentage of egg production , egg production and the number of egg mass production . Feed consumption showed P1 did not significant ( P > 0.05 ) with P2 , but was significantly higher ( P < 0.05 ) compared to P0 and P3 . Feed conversion showed P1 did not significant ( P > 0.05 ) with P2 and P3 but was significantly higher ( P < 0.05 ) compared to P0 . P0 shows the ration efficiency was significantly higher (P < 0.05) than the P1 , P2 and P3 . Based on the results of this study concluded that the effect of lemuru fish oil in feed based on oil sludge fermentation and extract of katuk leaves at a level of 2.5% , 5.0% and 7.5 % were not able to improve the performance of laying chicken , but this effect were able to give a performance
that were not different from the control feed.
