“…The composition of lauric, myristic, and palmitic acids (saturated fatty acids) of the Sapudi and Cross Merino showed low levels. This result was in line with Purbowati et al (2005), who reported that the fatty acid composition of lamb meat was also influenced by slaughtered weight and age; the younger sheep tended to have a higher lauric acid content than older sheep with a higher slaughter weight whose lowest saturated fatty acid content was at nine months of age with a slaughtered weight of 25 kg. In our study, no myristolic acid was found, while Purbowati et al (2005) reported that the myristolic acid content of local male sheep meat at 3, 7, and 9 months was 26.17 mg/100g, 27.36 mg/100g, and 17.53mg/100g, respectively.…”

Sheep meat plays an important role in accomplishing balanced and healthy nutrition as a source of protein, fat, and essential micronutrients such as zinc, iron, and vitamin B12. The amino and fatty acid composition of meat in different breeds need to be assessed to characterize and determine the development prospects of sheep that produce healthy and good quality meat. Therefore, this study aimed to investigate the phenotypic characteristics of the Sapudi and Cross Merino meat sheep including the carcass performance and meat qualities. We reared four Sapudi and four Cross Merino ewes in the same feed and environmental management for two months then slaughtered and analysed the carcass, non-carcasses and chemical meat properties. We used Bicep femoris muscle to perform proximate, amino acid, and fatty acid contents. An independent t-test was conducted to compared obtained data. Heart weight and protein content were higher in Sapudi sheep. Of the 51 fatty acids observed, we found 11 and 10 types of fatty acid in the Sapudi and Cross Merino meat, respectively. The fatty acid percentage of Sapudi meat tended to have higher value compared to Cross Merino. We also found that the two breeds have the same amino and fatty acid compositions. The levels of glycine, arginine, serine, tyrosine, phenylalanine, lysine and threonine were statistically higher in Cross Merino than Sapudi. In conclusion, the non-carcass, crude protein, amino acid and fatty acid level were significantly different between Sapudi and Cross Merino

“…Asam lemak palmitat selanjutnya dapat mengalami perpanjangan rantai dalam retikulum endoplasmik menjadi asam lemak rantai panjang lainnya. Kadar asam palmitat yang terlalu tinggi di dalam produk daging tidak diinginkan konsumen karena bersifat hiperlipidemik dan dapat meningkatkan kolesterol darah (Purbowati et al 2005 Berdasarkan Tabel 4 kandungan asam lemak jenuh laurat pada bintang laut Proteaster nodosus sebesar 0,04%. Asam laurat adalah asam lemak jenuh rantai sedang yang memiliki jumlah atom C 12.…”

Bintang laut Protoreaster nodosusatau disebut juga bintang laut bertanduk adalah hewan yang masuk kedalamfilum Echinodermata. Penelitian ini bertujuan untuk mengkaji nutrisi yang terkandung di dalam Protoreaster nodosusdengan melihat tiga parameter yaitu proksimat, asam amino dan asam lemak. Metode uji mengacu pada SNI 1992 (proksimat), AACC 1994 (asam amino), dan AOC 1984 (asam lemak). Hasil analisis proksimat pada Protoreaster nodosusmemberi nilai masing-masing air (50,40%), abu (33,60%), protein (9,19%), lemak (0,50%), dan karbohidrat (6,31%). Hasil analisis asam amino pada Protoreaster nodosusurutan tiga tertinggi ialah asam glutamat (2,45%), asam aspartat (1,08%), dan leusin (1,05%). Hasil analisis asam lemak pada Protoreaster nodosusurutan tiga tertinggi ialah asam palmitat (0,14%), asam stearat (0,07%), dan asam linolenat (0,07%).

ABSTRAKKinesin Family 12 (KIF12) merupakan gen yang terlibat dalam mediasi kaskade antioksidan dalam sel beta sebagai sebuah target intraselular dari kelebihan asupan lemak atau lipotoksit. Penelitian ini bertujuan untuk mengidentifikasi karakterisasai gen KIF12 melalui identifikasi keragaman dan asosiasi gen KIF12 terhadap komposisi asam lemak pada domba. Sampel domba yang digunakan sebanyak 35 ekor yang terdiri dari Domba ekor Gemuk (DEG) dan Domba Ekor Tipis (DET) masing-masing 20 dan 15 ekor. Titik mutasi gen KIF12 berada pada posisi g.9617965 C>T. Identifikasi keragaman gen KIF12 dianalisis menggunakan Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP) dengan menggunakan enzim BfaI. Hasil keragaman gen KIF12 bersifat polimorfik dengan ditemukan tiga genotipe yaitu CC, CT, dan TT. Hasil Uji chi square menunjukkan bahwa lokus KIF12 berada pada keseimbangan Hardy-Weinberg (HWE) pada pada DET, hal berbeda ditunjukakan pada DEG. Titik mutasi gen KIF12 berasosiasi secara signifikan (P <0.05) terhadap asam lemak jenuh (SFA) asam laurik (C12:0), asam miristik (C14: 0) and asam heptadenoik (C17: 0) juga asam lemak jenuh tunggal (MUFA), asam miristoleinik (C14: 1) and asam oleik (C18: 1n9c). Gen KIF12 memiliki potensi untuk digunakan sebagai penanda seleksi terhadap komposisi asam lemak.Kata kunci: domba, asam lemak, KIF12, PCR RFLPABSTRACTKinesin Family 12 (KIF12) is one of gene which involved in mediates an antioxidant cascade in beta cells as an intracellular target of excess fat intake or lipotoxicitys. This study was aimed to identify the polymorphism and association of KIF12 gene as candidate gene for fatty acid composition in Indonesian sheep including fat-tailed sheep and thin-tailed sheep. The sample of sheeps used 35 heads consist fat-tailed sheep and thin-tailed sheep as many as each 20 and 15 samples. Identification of polymorphism of KIF12|BfaI gene were analyzed using Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP). The results of polymorphism of KIF12 gene were polymorphic for three kind of genotypes of CC, CT, and TT. The chi square revealed that the locus of KIF12 was deviated in Hardy-Weinberg equilibrium (HWE) in fat-tailed sheep, but was in HWE in thin-tailed sheep. A SNP of KIF12 was associated (P <0.05) with saturated fatty acids (SFA) including lauric acid (C12:0), myristic acid (C14: 0) and heptadecanoic acid (C17: 0) as well as monounsaturated fatty acids (MUFA), namely miristoleinic acid (C14: 1) and oleic acid (C18: 1n9c).The KIF12 gene was the potential to be used as a marker of selection for fatty acid compositions.
