The relationship of the fatty acid composition of the three developmental stages (fingerling, juvenile and adult) of Heterobranchus longifilis (Pisces: Clariidae) and Chrysichthys nigrodigitatus (Pisces: Bagridae) have been evaluated by gas liquid chromatography (Glc) on polyethylene glycol-2-nitroterephthalic ester (PEGNTE). Results indicated that adults of these fishes, accumulated linolenic acid (C18:3w3) above dietary levels atthe fingerling stage which was remarkably depleted in the adult fishes. Its essentiality in their nutrition and metabolism is thus suggested. In the metabolic tumover,.C18:3w3, is utilized to build up the store of eicosapentaenoic acid (C20:5w3), inHeterobranchus longifillis while the store of eicosapentaenoic acis (C20:5w3),...

ABSTRACT This investigation was carried out to determine the effect of Essential Fatty Acids proportion (EFAs [n-6, n-3]) in feed through the mixture of soy, olive, canola or chia oil on EFA profile in eggs as well as productive and reproductive performance of Japanese quail. We used 120 quail from 7 to 22 weeks of age, in 15 cages in groups of 6 females and 2 males assigned according to the completely randomized design to 3 treatments with 5 replicates. The treatments were n-6:n-3 proportions 10:1 (control), 4:1 and 1:1. FA profile in yolk, feed intake, laying rate, egg weight, fertility, hatchability, and embryonic mortality were measured. In the egg yolk, n-6 content was similar in the proportions (p&gt;0.05), while n-3 content increased (p&lt;0.01) as...

between pro-inflammatory PUFA cis-linoleic (w6) and acachidonic (w6), versus the less inflammatory PUFA alpha-linolenic (w3), gamma-linolenic (w6), eicosapentaenoic (w3) and docosaeicosahenoic(w3) determines the fami1y of leukotrienes, prostaglandins and thromboxanes produced in the tissues, resulting in more or less inflammation (vasodilatation, aggregation, painful, etc.). Clinical studies have indicated positive effect of dietary relationship ofw6:w3 varying from 10:1to 2: I in inflammatory and coetaneous allergic diseases, arthritis, some tumors, kidney and cardiac disease, indicating a promising way to be explored.

Fatty acid profile in vertical strata of elephant grass subjected to intermittent stocking
Provedor de dados: 42
Autores: DIAS,KAMILA M.; SCHMITT,DANIEL; RODOLFO,GISELLE R.; DESCHAMPS,FRANCISCO C.; CAMARGO,GUILHERME N.; PEREIRA,RAPHAEL S.; SBRISSIA,ANDRÉ F.
ABSTRACT The milk and meat from animals with a pasture-based diet have higher proportions of CLA and C18:3 and lower omega-6:omega-3 ratios than products from animals with diets based on corn silage and concentrate. However, most of the published studies have evaluated fatty acid profiles in temperate climate grasses and the literature with tropical grasses is scarce. Thus, the aim of this study was to evaluate the morphological and fatty acid compositions in the vertical strata of elephant grass (Pennisetum purpureum Schum.) swards subjected to grazing heights (90 or 120 cm pre-grazing heights) and levels of defoliation (50% or 70% removal of the initial pre-grazing height). There were no interactions among pre-grazing height, the level of defoliation and...

Rice is a tropical plant, so cold temperature may be detrimental to its development, depending on the genotype and environmental conditions. Degree of lipid unsaturation has been related to cold tolerance due to its effect on membrane stability. So, the aim of this study was to characterize the fatty acid composition and its alterations due to cold temperature in rice genotypes of diversified origin. Forty-four rice genotypes at the V4 stage were submitted to two temperature conditions: 10°C and 28°C for two days and after this they had their leaves collected for lipid extraction and quantification. Control plants were allowed to regrow until presenting four leaves fully expanded and then were subjected to 10°C for ten days for cold tolerance evaluation....

Effect of temperature on polyunsaturated fatty acid accumulation in soybean seeds
Provedor de dados: 61
Autores: Lanna,Anna Cristina; José,Inês Chamel; Oliveira,Maria Goreti de Almeida; Barros,Everaldo Gonçalves; Moreira,Maurilio Alves.
Soybean oil contains around 60 % of polyunsaturated fatty acids, which are responsible for the low oxidative stability of soy-derived products. Soybean lines with low linolenic acid content can be obtained by genetic manipulation; however, a high proportion of the variation in fatty acids content is due to environmental factors. This work aimed to determine the effect of temperature on oil composition and on the activity of the enzymes CDP-choline:1,2-diacylglycerolcholine phosphotransferase (CPT) and acyl-CoA:lysophosphatidylcholine acyltransferase (LPCAT), responsible for maintenance of polyunsaturated fatty acids in the cytoplasmic acyl-CoA pool, that is used for oil synthesis in the seeds. CAC-1, a soybean variety with linolenic acid content of about 8...

Provedor de dados: 117
Autores: Berti,Marisol; Fischer,Susana; Wilckens,Rosemarie; Hevia,Felicitas; Johnson,Burton.
Flaxseed (Linum usitatissimum L.) is imported into Chile mostly for bread making and feed. Identification of genotypes best adapted for seed production in South Central Chile would facilitate producer’s decision. The objective of this study was to determine the adaptation and genotype x environment interaction of 16 flaxseed genotypes (including 10 from North American and six from Argentine sources) grown at 11 environments (defined as location-year) in Chile from 2003 to 2007. Genotype seed yield was above 5700 kg ha-1 for some environments indicating a high yield potential. According to the AMMI (Additive Main Effects and Multiplicative Interaction) and SREG (Sites regression) models the 11 environments were classified into four groups by the AMMI and...
