Cultivation of salt-tolerant crops help to face to irreversible global salinization of freshwater and soils. In New-Caledonia, three halophytes are candidates for saline crops, Salsola australis R.Br., Suaeda maritima (L.) Dumort and Enchylaena tomentosa R.Br. Their success and quality depend yet on availabilities of salinity and essential nutrients in agrosystems. So, we investigated effects of three salinities, i.e., control moderate and high, and five nitrogen ratios, i.e., 100:0, 75:25, 50:50, 25:75 or 0:100 NO3−-N:NH4+-N ratio on their growth and functional value for fatty acids and antioxidants. Results show that the leaf fatty acid and antioxidant profiles of species, emphasize their good potential to become functional crop products, based on...

Environmental anomalies, energetic reserves and fatty acid modifications in oysters coincide with an exceptional mortality event
Provedor de dados: 5
Autores: Pernet, Fabrice; Barret, Jean; Marty, Claire; Moal, Jeanne; Le Gall, Patrik; Boudry, Pierre.
Mortality of oysters Crassostrea gigas occurred along the coasts of France during summer 2008, causing a serious crisis in French oyster production. During spring to summer 2008, 5 groups of 1-yr old oysters of different origins and ploidy levels deployed in the Thau lagoon (France) were sampled for biometrical and biochemical analyses; environmental parameters were monitored in the same area. Mortality occurred in 2 episodes: 13 May to 10 June and 24 June to 9 July. Wild-collected oysters showed mortality sooner than other groups but total overall mortality was 85% in all groups. Mortality occurred when seawater temperature was &gt;19 degrees C during the reproductive season when energetic reserves of oysters were at their lowest. Energy reserve levels...

Lipid nutrition and settlement behaviour in American lobster Homarus americanus
Provedor de dados: 5
Autores: Theriault, I; Pernet, Fabrice.
This study examines the effects of varying dietary lipids on growth, survival, lipid composition and behaviour in lobster Homarus americanus (Milne Edwards, 1837) postlarvae. Lobsters were fed one of 3 diets during their early ontogeny: (1) Artemac, a widely used Artemia replacement; (2) a ternary mixture consisting of Artemac, frozen Artemia adults and Artemia flakes; or (3) a mixture of live A. salina nauplii and adults. We evaluated the olfactory capacity (response to predator odour plume) and cryptic behaviour (ability to hide during settlement) of lobster postlarvae as a function of these diets and the lipid and the fatty acid composition of lobsters. Growth and survival of lobster postlarvae were highest in those fed live Artemia, followed by the...

Essential Fatty Acid Assimilation and Synthesis in Larvae of the Bivalve Crassostrea gigas
Provedor de dados: 5
Autores: Da Costa Gonzalez, Fiz; Robert, Rene; Quere, Claudie; Wikfors, Gary H.; Soudant, Philippe.
Essential fatty acids (EFA) are important for bivalve larval survival and growth. The purpose of this study was to quantitatively assess for the first time through a mass-balance approach dietary EFA incorporation and synthesis within Crassostrea gigas larvae. A first experiment was carried out using two microalgae, Tisochrysis lutea (T) and Chaetoceros neogracile (Cg), as mono- and bi-specific diets. A second experiment using a similar design was performed to confirm and extend the results obtained in the first. Flow-through larval rearing was used for accurate control of food supply and measurement of ingestion. Non-methylene-interrupted fatty acids were synthetized from precursors supplied in the diet: 16:1n-7 and 18:1n-9, mediated by Delta 5...

Modulation des performances cardio-respiratoires du bar europeen (Dicentrarchus labrax) par l'apport d'acides gras alimentaires: une etude integree des effets cardiaques in vivo au courant calcique de type L des myocytes ventriculaires
Provedor de dados: 5
Autores: Chatelier, Aurelien.
Diet quality, and particularly fatty acids composition, is an environmental factor that is emerging as a significant source of physiological diversity. Indeed, numerous recent studies show that the fatty acid composition of the diet influences cardiac and metabolic performances of organisms. Because it is involved in the control and regulation of internal flow of matter and energy, the heart is believed to play a central role in environmental adaptation in fish. Within the double context of adaptation of individuals to their ecological niche and species evolution, understanding sources of interindividual variability and particularly fatty acid influences on the cardiorespiratory system is essential.  The objective of the study was to investigate in the sea...

Effects of oleic acid on the high threshold barium current in seabass Dicentrarchus labrax ventricular myocytes
Provedor de dados: 5
Autores: Chatelier, Aurelien; Imbert, Nathalie; Zambonino, Jose-luis; Mckenzie, David; Bois, P.
The present study employed a patch clamp technique in isolated seabass ventricular myocytes to investigate the hypothesis that oleic acid (OA), a mono-unsaturated fatty acid, can exert direct effects upon whole-cell barium currents. Acute application of free OA caused a dose-dependent depression of the whole-cell barium current that was evoked by a voltage step to 0 mV from a holding potential of -80 mV. The derived 50% inhibitory concentration (IC50) was 12.49 +/- 0.27 mu mol l(-1). At a concentration of 30 mu mol l(-1), OA significantly reduced the current density to about 45% of control values, but did not modify either the shape of the current-density voltage relationship or the apparent reversal potential. In addition, OA did not modify the voltage...

Remodeling of membrane lipids in gills of adult hard clam Mercenaria mercenaria during declining temperature
Provedor de dados: 5
Autores: Parent, G; Pernet, Fabrice; Tremblay, R; Sevigny, J; Ouellette, M.
In a previous study, a major remodeling of lipids, consistent with the theory of homeoviscous adaptation, was observed in the juvenile hard clam Mercenaria mercenaria during a temperature reduction from 24 to -1 degrees C. In addition, the lipid remodeling varied between genetically distinct lines of hard clams. The present study examined whether adult hard clams originating from different locations and a selectively bred variety show differences related to their genetic characteristics in the remodeling of lipids that normally occur during decreasing temperatures. Wild hard clams from 4 locations in Atlantic Canada and the selectively bred M mercenaria var. notata were held at an aquaculture growout site located at the northern distribution limit of the...

Provedor de dados: 5
Autores: Hamza, N; Mhetli, M; Ben Khemis, I; Cahu, Chantal; Kestemont, P.
This study was carried out to evaluate the effects of dietary phospholipid on the development and rearing performance of pikeperch (Sander lucioperca) larvae. From day 10 post-hatching, fish larvae were weaned onto three isoproteic and isolipidic formulated diets with different phospholipid (PL) levels: 1.4 (PL1), 4.7 (PL5) and 9.5% (PL9) of dry matter, as soybean lecithin. Neutral lipid (NL) with inversed gradient was incorporated in diets. Survival, growth and deformities were monitored until day 34 post-hatching, as well as intestinal enzyme activities, leucine alanine peptidase (leu-ala), aminopeptidase N (AN) and alkaline phosphatase (AP), which were used as indicators of digestive tract maturation. This study showed that PL supplementation...

Associations between tissue fatty acid composition and physiological traits of performance and metabolism in the seabass (Dicentrarchus labrax)
Provedor de dados: 5
Autores: Chatelier, Aurelien; Mckenzie, David; Prinet, Aurelie; Galois, Robert; Robin, Jean; Zambonino, Jose-luis; Claireaux, Guy.
Seabass were fed for 4 months with diets where the lipid was provided as either canola oil (CO), palm oil ( PO) or fish oil (FO), to generate diversity in their tissue fatty acid (FA) composition and investigate how this influenced major traits of exercise performance, cardiac performance and respiratory metabolism. In particular, based upon previous observations, we investigated the hypothesis that enriching the fish tissues with oleic and linoleic acids (OA, 18:1n-9 and LA, 18:2n-6, respectively) from the CO and PO diets would improve maximum exercise and cardiac performance, and increase aerobic metabolic scope. This proved to be the case; exercise respirometry on bass fitted with cardiac flow probes revealed that those fed CO and PO diets had a...

Biological, nutritional, and histochemical basis for improving an artificial diet for Bracon hebetor Say (Hymenoptera: Braconidae)
Provedor de dados: 82
Autores: Magro,Sandra R.; Dias,Alcides B.; Terra,Walter R.; Parra,José R.P.
The biology of Bracon hebetor Say (Hymenoptera: Braconidae) reared on fifth instars of Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) (natural diet) and in vitro (artificial diet) was evaluated. Data on the number of instars, development time and food intake were collected, and histochemical tests were conducted to detect proteins and lipids in the parasitoid's digestive tract. The data disclosed differences that can help to improve artificial rearing of B. hebetor. B. hebetor had three instars in both diets, but the developmental time on the artificial diets was prolonged due to the increase in larval and pupal development times. Larvae grew faster on the natural host and required a lower food intake (2.7 µl) as compared to that required by the...

Provedor de dados: 89
Autores: Chung,TH; Choi,IH.
ABSTRACT In this study, 240 one-d-old Arbor Acres broiler chicks (160 males and 80 females) were randomly allocated in a completely randomized design with four treatments and four replicates. Broilers were fed from hatching to 28 d of age four diets: a basal diet (control), 2% red ginseng marc, 1% fermented red ginseng marc with red koji, and 2% liquid red ginseng. Growth performance and fatty acid profiles in broiler were evaluated. Supplementing diets with different types of red ginseng did have significant effects (p&lt;0.05) on initial body weight, due to differences in the birth weights of birds, including weight gain, and mortality. However, no significant differences between the treatments (p&gt;0.05) were found for final body weight, feed intake,...

The quality of lamb fat is important in sheep carcass markets because it affects the degree of acceptance by consumers. In Spain, consumption of beef and lamb is important and young lambs are highly valued. In addition, the precocity of the female determines slaughter at younger ages than males, to avoid excessive fat. Therefore, the effect of sex and fat depot location (omental, mesenteric, kidney knob, subcutaneous, intermuscular and intramuscular) on the fatty acid composition in 30 Rasa Aragonesa lambs (15 males and 15 females) of 24 kg live weight and three months of age, were studied. Oleic, palmitic and stearic fatty acids were the main fatty acids making up the fat in all the fat depots from lambs. There were no significant differences (p&gt;0.05)...

Provedor de dados: 52
Autores: Pessoa,José Dalton Cruz; Arduin,Marcos; Martins,Maria Alice; Carvalho,José Edmar Urano de.
The aim of this work was to study the source of the açaí residue for its possible commercial applications by characterizing the fruit (fresh and dry mass), and performing an anatomic study of the pericarp from which were identified the origin of the anthocyanins, and fatty acids, and fibers; also the vascular system, its fibers constituents and fibrils were characterized. It was concluded that anthocyanins were located on the epiderm and external parenchyma, and that solids retained on the sieve come from the sclerenchyma, and that the fatty acids come from the storage parenchyma. The vascular tissue was formed by the fibers around 20 mm length. The length distribution of the fibrils had a mean length of 580µm.

We determined the influence of fasting (FAST) and feeding (FED) on cholesteryl ester (CE) flow between high-density lipoproteins (HDL) and plasma apoB-lipoprotein and triacylglycerol (TG)-rich emulsions (EM) prepared with TG-fatty acids (FAs). TG-FAs of varying chain lengths and degrees of unsaturation were tested in the presence of a plasma fraction at d &amp;gt; 1.21 g/mL as the source of CE transfer protein. The transfer of CE from HDL to FED was greater than to FAST TG-rich acceptor lipoproteins, 18% and 14%, respectively. However, percent CE transfer from HDL to apoB-containing lipoproteins was similar for FED and FAST HDL. The CE transfer from HDL to EM depended on the EM TG-FA chain length. Furthermore, the chain length of the monounsaturated...

Pequi is the fruit of Caryocar brasiliense and its oil has a high concentration of monounsaturated and saturated fatty acids, which are anti- and pro-atherogenic agents, respectively, and of carotenoids, which give it antioxidant properties. Our objective was to study the effect of the intake of a cholesterol-rich diet supplemented with pequi oil, compared to the same diet containing soybean oil, on atherosclerosis development, and oxidative stress in atherosclerosis-susceptible LDL receptor-deficient mice (LDLr-/-, C57BL/6-background). Female mice were fed a cholesterol-rich diet containing 7% soybean oil (Soybean group, N = 12) or 7% pequi oil (Pequi group, N = 12) for 6 weeks. The Pequi group presented a more atherogenic lipid profile and more advanced...

Autores: Brestenský,Matej; Nitrayová,Soňa; Patráš,Peter; Heger,Jaroslav; Nitray,Jozef.
ABSTRACT: In the present study it was evaluated the effect of the addition of linseed oil, inulin and horse chestnut added to a high fat (HF) diet on the content of fatty acids (FAs) in musculuss longissimus dorsi (MLD) of pigs. A 5d with adaptation period was followed by a 70 d experimental period, during which the pigs were fed with a HF basal diet. The HF basal diet which served as a control (group CG) was supplemented either with linseed oil (group LG) or with inulin and horse chestnut (group IG). All of the pigs were slaughtered at the end of the experiment and samples of MLD were taken for FA analysis. The concentration of α-linolenic acid in MLD of the LG group was 58 % and 61 % higher (P˂0.05) compared to CG and IG groups, respectively. The content...

Provedor de dados: 65
Autores: Liu,Qinhua; Dong,Zhihao; Shao,Tao.
ABSTRACT: The objective of present study was to investigate the dynamics of change in fermentation and fatty acid profiles in high moisture (DM=232g/kg FW) alfalfa silages during ensiling at 45°C, 30°C and 15°C. After ensiling for 1, 3, 7, 21, 39 and 65 days, silages was sampled and examined. Lactic fermentation changing into butyric fermentation in silage ensiled at 30°C and 45°C occurred on ensiling for 21 and 65 days, respectively, as accompanied with high ammonia-N content ( &gt;150g/kg N), which subsequently resulted in a sudden increase of pH (P &lt; 0.05). In contrast, the increase of lactic acid content was observed in silage ensiled at 15°C during ensiling for 65 days (P&lt;0.05). As the ensiling temperature rose, considerable losses in total FA,...

Peripartum is a critical period for dairy goats, as dry matter intake (DMI) is not enough to supply the energy requirement for foetal growth and subsequent lactation. The objective of this study was to evaluate the use of calcium salts of fatty acids (CSFA) to increase dietary energy level of peripartum dairy goats and its effects on nutritive value of diets and milk quality. Twenty multiparous Saanen goats (body weight 63.5±10.3 kg) were distributed in a completely randomised design in four treatments at the following dietary energy levels: 2.6 Mcal of metabolisable energy per kg of dry matter (Mcal ME/kg DM) - control diet; and 2.7, 2.8, and 2.9 Mcal/kg DM - with added CSFA. Goats were housed in individual stalls and evaluated in the peripartum period,...
