The study was conducted to investigate the fatty acid profile of intramuscular fat in longissimus lumborum (LL) of three genotypic groups: Qazvinian native (Q, n=10), crossbred Qazvinian native × Saanen breed (QS, n=10) and backcrossed Qazvinian native × Saanen breed (QSS, n=9) male kids.All of kids were weaned at 75-days-old and then fed with a diet consisted of concentrate (70%) and alfalfa h...

BACKGROUND Studies of the relation between polyunsaturated fatty acids and risk of atrial fibrillation have been inconclusive. The risk of atrial fibrillation may depend on the interaction between n-3 and n-6 polyunsaturated fatty acids as both types of fatty acids are involved in the regulation of systemic inflammation. OBJECTIVE We investigated the association between dietary intake of long...

Nutritional value of freshwater mesozooplankton, fatty acid (FA) and amino acid (AA) compositions were determined in the middle of each season for a one-year period from May 2009 to February 2010 in Hanna Dam Lake, Isfahan, Iran. FA and AA composition significantly (P < 0.05) varied in relation to the seasonal changes of water quality, phytoplankton and zooplankton community. The content of sat...

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...

objective: although key roles for dietary vitamin e (vite) and fatty acid (fa) in fertility have been confirmed, limited data are available on the effects of vite alone, or a constant level of vite supplemented by dietary omega-6 and omega-3 fas in combination on male reproduction. consequently in this paper, the effects of vite, sunflower oil, fish oil and their combination on rat sperm were i...

introduction: cholesterol and fatty acids are two important components of the lipids. various fatty acids have different effects on plasma lipoproteins. consumption of saturated fatty acids tends to increase total plasma and ldl cholesterol levels. while  polyunsaturated fatty acids reduce both ldl and hdl cholesterol, edible oil rich in monounsaturated fatty acid (mufa) however, tend to lower ...

Various science researches have shown that meat of ruminants has more desirable fatty acid composition and a ratio between ω-6 and ω-3 fatty acids (lower than 4.0) because of lower content of linoleic, and a higher content of ω-3 polyunsaturated fatty acids, especially linolenic fatty acid. The aim of the present study is to examine researches about feeding modulation of the fatty acid composit...

  Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P<0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fat,...
