چکیده

objective: the effects of dietary fish oil on semen quality and sperm fatty acid profiles during consumption of n-3 fatty acids as well as the persistency of fatty acids in ram’s sperm after removing dietary oil from the diet were investigated. materials and methods: in this experimental study, we randomly assigned 9 zandi rams to two groups (isoenergetic and isonitrogenous diets): control (ctr; n=5) and fish oil (fo; n=4) for 70 days with a constant level of vitamin e in both groups. semen was collected at the first week and at the last week of the feeding period (phase 1). after the feeding period, all rams were fed a conventional diet and semen samples were collected one and two months after removal of fo (phase 2). the sperm parameters and fatty acid profiles were measured by computer assisted semen analyzer (casa) and gas chromatography (gc), respectively. the completely randomized design was used and data were analyzed with spss version 16. results: dietary fo had significant positive effects on all sperm quality and quantity parameters compared with the ctr during the feeding period (p<0.05). the positive effects of fo on sperm concentration and total sperm output were observed at one and two months after removal of fo (p<0.05), whereas other sperm parameters were unaffected. before feeding, c14 (myristic acid), c16 (palmitic acid), c18 (stearic acid), c18:1 (oleic acid) and c22:6 (docosahexaenoic acid: dha) were the primary sperm fa. fo in the diet increased sperm dha, c14:0 and c18:0 during the feeding period (p<0.05). conclusion: the present study showed not only manipulation of ram sperm fatty acid profiles by dietary fo and sperm parameters during the feeding period, but also the persistency of unique effects of dietary omega-3 fatty acids up to two months following its removal from the diet. also, we recommend that sperm fatty acid profiles should be comprehensively analyzed and monitored.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Oil and Fatty Acid Profiles of Soybeans

Soybean oil contains 14 fatty acids and five of them, C16:0, C18:0, C18:1, C18:2, and C18:3, are considered essential fatty acids for proper human nutrition. Increasing the oil content and improving the ratio of the various fatty acids in soybeans is a goal for many breeding programs. The objective of this research was to evaluate the relationship between grain yield, oil content, and fatty aci...

P-122: Sperm Intracellular Reactive Oxygen Species Incidence in Ram Fed A Diet with Fish Oil

Background: Basal level of reactive oxygen species (ROS) is essential for sperm acrosomal reaction, hyperactivation, motility, capacitation and fertilization. Ram spermatozoa contain large quantities of polyunsaturated fatty acids in their plasma membranes so are extremely susceptible to ROS induced damage. Materials and Methods: Eight rams (36 ± 5 month of age and with a weight of 64 ± 7 kg) w...
