The aim of this study was to investigate fatty acids, fat-soluble vitamins, malondialdehyde and cholesterol in conventional and organic eggs obtained from hens of different ages (30 and 60 weeks). A total of 360 egg yolks were used in this study. Polyunsaturated fatty acid, omega-3, and omega-6 levels were higher in the organic eggs from the 30-week-old hens. The monounsaturated fatty acid level was higher in the conventional eggs but was the same between the two age groups. Cholesterol and vitamin A levels were not influenced by either the rearing system or the age of the hens. The malondialdehyde, vitamin D2, and vitamin K2 were higher in the organic eggs; however, vitamin E was higher in the conventional eggs. The results showed that the rearing system and age, as well as the diet, had an impact on the composition of the egg. Total levels of polyunsaturated fatty acid, omega-3, and omega-6 are higher in organic eggs produced by younger hens.

Minyak ikan patin mengandung kadar asam lemak omega-9, tetapi rendah asam lemak omega 3 Minyak hati ikan hiu memiliki kandungan asam lemak omega 3 relatif tinggi. Penelitian ini bertujuan untuk menentukan karakteristik dan sifat kimia minyak ikan patin dan profil asam lemak kombinasi minyak ikan patin dengan hati kan hiu. Metode penelitian eksperimen dengan melakukan ekstraksi lemak perut ikan patin secara dry rendering dihasilkan minyak kasar dan dimurnikan. Minyak ikan patin murni dilakukan pencampuran dengan minyak hati ikan hiu. dengan perbandingan 1:1, 2:1 dan 2:1. Parameter analisis terdiri atas karakteristik kimia (bilangan asam lemak bebas (ALB),bilangan  asam, peroksida, iod,  p-anisidin, penyabunan, total oksida/totox), dan profil asam lemak. Hasil penelitian menunjukkan bahwa kombinasi  minyak patin dan hati ikan hiu dihasilkan karakteristik kimia terdiri atas asam lemak bebas sebesar 1,59-2,19%, bilangan asam 2,86-3,00 mg KOH/g, peroksida 15,50-18,32 meq/kg, iod 63,46-84,42 gI2/100g), p-anisidin 21,53-24,16, penyabunan 142,21-162,28 mg KOH/g dan TOTOX 53,33-69,43. Hasil analisis komposisi asam lemak jenuh (saturated fatty acid/SAFA) dihasilkan  asam palmitat tertinggi,  asam lemak tak jenuh tunggal  (mono unsaturated fatty acid/MUFA)  asam oleat,  dan asam lemak tak jenuh ganda (polyunsaturated fatty acid/PUFA)  asam linoleat. Hasil analisis karakteristik kimia kombinasi  minyak ikan patin dan hati ikan hiu sesuai dengan standar IFOMA. Kombinasi minyak hati ikan hiu dan ikan patin dengan perbandingan (2:1) dihasilkan kandungan omega 3 dan omega 6 sebesar 2,59 % dan 29,75%.

The effect of dietary HM on plasma and egg yolk lipids of commercial White Leghorn hens was studied over 350 d. A total of 192 birds were given corn-wheat-soybean meal diets that contained either 0, 4, 8, or 12% HM. Analysis of plasma lipids at four periods in the laying cycle (169, 211, 253 and 287 d) and at five times during the test day (0800, 1000, 1200, 1400 and 1600 h) were performed. Egg lipids were analyzed at each of the four periods.Plasma total lipids were inversely related (P < 0.01) to dietary HM levels while omega-3 and omega-6 fatty acid levels were positively and inversely related (P < 0.001), respectively. HM levels did not influence the total lipid content of the egg yolk lipids but omega-3 and omega-6 fatty acid content were positively and inversely related, respectively. The levels of eicosapentaenoic (20:5n3, EPA) and docosahexaenoic (22:6n3, DHA) acid were 11 and 3 times higher, respectively (7.8 and 100.5 mg yolk−1) in the yolks from hens given the 12% HM diet compared to the control diet. Key words: Herring meal, laying hens, omega-3 fatty acids, eicosapentaenoic acid, docosahexaenoic acid

Kidney Functions

Arachidonic acid (ARA), an omega-6 (ω-6) polyunsaturated fatty acid (PUFA), is involved in the development and maintenance of renal functions, whereas docosahexaenoic acid (DHA) is an omega-3 (ω-3) PUFA that has anti-inflammatory effects and attenuates nephropathy. However, their effects on the progression of chronic kidney disease (CKD) remain unknown. The aim of this study was to assess the effects of feeding ARA, DHA, and ARA and DHA-containing diets on rats with 5/6 nephrectomized kidneys. Urine and feces were collected every 4 weeks, and the kidneys were collected at 16 weeks after surgery. Urinary albumin (U-ALB) excretion increased gradually with nephrectomy, but the U-ALB excretion was attenuated by feeding the rats with an ARA + DHA-containing diet. Reactive oxygen species (ROS) levels in the kidneys were lower in the ARA + DHA group than in the other groups. At 4 weeks after surgery, the lipid peroxide (LPO) levels in the plasma of the ARA + DHA groups decreased significantly after surgery compared to the control CKD group, but this did not happen at 16 weeks post-surgery. There was a significant negative correlation between LPO levels in the plasma at 4 weeks and creatinine clearance, and a positive correlation with urinary albumin levels. These results suggest that the combination of ARA and DHA inhibit the progress of early stage CKD.
