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...

The aim of the present study was to determine and compare the seasonal changes in the proximate composition, fatty acids profile and fat soluble vitamins content in spring and autumn goby (Neogobius melanostomus) caught from the Bulgarian Black Sea waters. The proximate composition (moisture, protein and total lipid) has been determined according to AOAC (1990).  Analysis of fatty acid methyl e...

INTRODUCTION Infertility in men is one of the current problems of human society. Some studies suggest that the metabolic status of a man, including cholesterol intake, closely correlates with sperm function. The aim of this study was to evaluate the correlation between saturated fat intake and semen quality among men referring to the Isfahan Fertility and Infertility Center, Iran. MATERIALS A...

The effects of the use of essential oil of Rosmarinus officinalis on the chemical quality and fatty acids of fish fillets of Ctenopharyngodon idella were investigated during frozen storage at -18 ºC for 6 months. Fish fillets were divided into three groups the control (C) without rosemary essential, the second group with 0.2 % rosemary essential oil (A) and the third with 0.4 % rosemary essenti...

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...

The total lipid content and composition of fatty acids of the liver and muscles of wild and cultured male and female Acanthopagrus latus were determined by gas-liquid chromatography. There were quantitative differences between individual fatty acids in the tissues investigated depending on sex and location. In all the samples studied, sex and location considered, the principle saturated fatty a...

Introduction Lipids are the main source of energy in metabolism of spermatozoa. The fatty acids are both structural elements and bioactive compounds (1). In most mammals, docosahexaenoic acid (DHA) is the dominant polyunsaturated fatty acid, although, in several species docosapentaenoic acid (DPA) is also a major component of the sperm cell membrane (2). The high quantity of long chain polyunsa...

The aim of this study was to investigate the effect of dietary supplementation of long chain fatty acids (C > or = 20 LCP) of the n-3 series, vitamin E and vitamin C on the antioxidant capacity of rabbit buck and on semen characteristics. Fifty male rabbits at 30 days were randomly assigned to five different diets: Control (50 mg x kg(-1) diet alpha-tocopheryl acetate), Vitamin E (200 mg x kg(-...
