Background: Mammalian spermatozoa are characterized by a high proportion of polyunsaturated fatty acids (PUFA) and the membrane structure of spermatozoa plays a crucial role in fertilization. Moreover, dietary fatty acid (FA) influence sperm FA profiles in several species. This study focused on responses to dietary omega-3 fatty acids and comprehensive fatty acid profiles analysis in men as wel...

abstract  introduction: this experiment was conducted to study the effects of different levels of flaxseed (0, 5, 10 and 15% of diet) and copper (in the form of cupric sulfate pentahydrate, 0 and 250 ppm of diet) on fatty acids and cholesterol in egg yolk of laying hens. methods: a total of 128 white leghorn layers aged 50 weeks were used in a factorial design and randomly assigned to 8 treatme...

Background: Feeding unsaturated fatty acids sources in dairy cows is considered as a strategy to improve animal health during postpartum period and milk fatty acid profile. OBJECTIVES: This study aimed to investigate the effects of conjugated linoleic acid supplement and combination of sesame meal and oil on performance and milk fatty acid composition of dairy cows during transition period. MET...

In this study, seasonal variations in the fatty acid profiles of the liver and muscle of Squalius cephalus from Tödürge Lake were determined by Gas Chromatography (GC). C22:6 n-3, C20:5 n-3, C20:4 n-6, C18:1 n-9, C18:1 n-7, C16:1 n-7, C18:0 and C16:0 were the principal fatty acids showing the highest levels in the muscle and liver of Squalius cephalus in all seasons. Although C22:6 n-3, which i...

changes in the fatty acid composition and biochemical indices of mackerel (which has a substantial lipid content) and shark (which has negligible lipid content) fillets stored at - 18°c for up to six months were measured. lipid content was measured (6.35% and 1.38%) in mackerel and shark, respectively; however it decreased during frozen storage in both fish species. in analysis of fatty acids t...

serum fatty acids on 30 healthy lranian women were detemined by a gas chromatographic method. oleic and stearic acids were used as standards. the mean values were myristic acid 5. 7% , palmitic acid 43% , palmitoleic acid 5.3% , stearic acid 8% , oleic acid 21. 3% and linleic acid 16.4% of total fatty acid serum contents.

Heart failure (HF) incidence increases worldwide and is affected by various risk factors such as coronary artery disease, hypertension, obesity, and diabetes. Dietary recommendations for patients with HF have generally focused on sodium restriction; however, different nutritional approaches are considered in patients with a high risk of malnutrition due to the diuretic drugs they use. Omega-3 f...

enzymatic acidolysis of canola oil through caprylic and capric acids was investigated for making structured lipids. lipozyme tl im, an sn-1,3 specific thermomyce slanuginosa lipase, was utilized as the biocatalyst in the batch reactor. reaction conditions were designed according to taguchi’s method considering fatty acid to oil ratio, at three levels (1:1, 2:1, 3:1) , enzyme load (4, 8 and, 12%...

background: application of different sources of fatty acids and their effect on ovarian performance is a current issue in animal science and research centers. objectives: the purpose of this study was to determine the effect of different fatty acids in close-up period on population and size of follicles and measuring blood parameters related to the energy state of the body after calving of lact...
