ABSTRAC AMILUDDIN INDI. H4A 004 001. Chemistry and Physic Quality of Lohmann Brown Eggs as a result of Lemuru COD (Sardinella Longiceps) Feeding. (Counselor : EDJENG SUPRIJATNA dan LUTHFI D. MAHFUDZ) This Research aim to identify the effect of lemuru cod feeding in ration, as an effort to increase the omega-3 content, decrease cholesterol degree in eggs and produce good quality eggs. Research conducted in Balebat Farm, sukorejo village, Kendal Regency. The material used are 120 horn chicken, with age of 22 weeks and average early weight of 1.745,2 ± 8,26 g. the ration used is arranged based on isoprotein. The experiment using complete random program (rancangan acak lengkap/RAL) with 5 treatments consists of R0: ratio without lemuru cod adding;R1: 1,5% of ration and lemuru cod; R2: 3% of ration and lemuru cod; R3 4,5% of ration and lemuru cod; R4: 6% of ration and lemuru cod. Every treatment has repeated 4 times, and every rrpetition has filled by 6 layer period chicken. Data has processed statistically by variety analysis. If there are any treatment effect, it will be continued with Duncan doubled distance test. The result research shows that the lemuru cod feeding in ransom has bring tangible effect (p<0,05) to the cholesterol content successively from R0 to R4: 230,07 to 157,24 mg/egg. Increasing EPA content from R0 to R4: 0,28 to 0,67%. DHA from R0 to R4: 0,81 to 5,01%. The analysis shows that the lemuru cod feeding in ratio has been tangible effect (P<0,05) to the egg physic quality. The egg yolk color score from R0 to R4: 6,750 to 0,080; the eggshell thickness from R0 to R4: 0,346 to 0,658 mm, haugh unit from R0 to R4: 87,673 to 98,688, eggs index from R0 to R4: 79,165 to 72,020, the eggyolk index from R0 to R4: 0,435 to 0,805 g Conclusing of the research is that the lemuru cod feeding in ration has decrease the cholesterol content and increase the omega-3 fat acid in eggs and increase the eggyolk color, eggshellthickness, haugh unit, eggyolk index with the lemuru cod feeding in ransom to 6% can be used for layer period chickens.
