the present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. zel ewes (n=188) were assigned to 4 groups. ewes in the control group (con) did notreceive fat. ewes in the 3 other groups received 3% oil/dm/day of palmolein oil (pl...

chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (pufas) are required for both animal and human health. the n-3 pufas, especially, eicosapentaenoic acid (epa) and docosahexaenoic ...

the objectives of this study were to determine the effects of feeding rapeseed (27%, dm basis) and sunflower biodiesel by-products as protein supplements on fatty acid composition (fa), profile (ratios and indices),enzyme activitiesfrom thecarcassin lambs fed cereal-based diets. simultaneously, itwas examined the relationship between ingested fa and carcass fa. samples were obtaine dfrommal efa...

background: fatty acids are the main compounds in edible oils. oil thermal stability depends on the composition of fatty acids. so, this study was conducted to investigate the effect of fatty acid composition on the oxidative stability of extra virgin olive oil during heating process.  methods: totally, eight virgin olive oil samples, including five imported oils from market place of mahabad an...

Exposure of Listeria innocua to acid and starvation stress decreases sensitivity to the quaternary ammonium compound cetrimide, whereas exposure to cold and heat stress increases sensitivity to this compound. Changes in membrane lipids occur in response to certain types of stress, and these changes likely impact cell sensitivity to chemical sanitizers. The present study included an assessment o...

Short chain (C2-C6) fatty acids are produced in the colon through bacterial fermentation of mainly dietary fibre. Butyrate (C4) possesses antineoplastic effects on human colon carcinoma cells, and epidemiological studies indicate that high fibre diets may reduce the incidence of colorectal cancer. The role of dietary fibre during colorectal carcinogenesis might therefore be related to its ferme...

In this study fatty acid contents, because of the importance in human’s life, and their seasonal variations of a dominant bivalve of Haleh Creek were determined for the first time. Fatty acid identification was done by GC-MS (Gas Chromatography–Mass Spectrometry) method. After collecting and dissecting the species from the shells, samples weighed and frozen for further experiments. All the samp...

Fatty acids composition in edible parts of Blue Swimming Crab (Portunus pelagicus) caught in the Persian Gulf close to the Bushehr Province were investigated. Among saturated fatty acids (SFA), the 16:0 and 18:0 fatty acids were the most two dominant fatty acids in meat tissues that analyzed. 18:1n-9 and 16:1n-7 were the major fatty acids among the MUFAs of male and female crab. The main PUFAs ...
