Calidad de la canal y carne de corderos complementados con aceites y rastrojo de maíz. Colegio de Postgraduados
Hernández Cruz, Laura.
El estudio se realizó con 48 corderos de la cruza Pelibuey x Katahdin de aproximadamente 4 meses de edad con un peso promedio de 29 ±1.2 kg los cuales se distribuyeron en un diseño completamente al azar, en arreglo factorial 2x4; los tratamientos fueron: 1) Sin aceite (C), 2) 3% de aceite con ácido linoleico conjugado (CLA), 3) 3% de aceite con ácido linoleico (LA) y 4) 3% de aceite de linaza (LZ); y dos porcentajes de rastrojo de maíz por kg de MS-1 (16 y 26). Los resultados en GDP y CMS/GDP no presentaron diferencias, sin embargo, el CMS fue menor (P<0.05) cuando se proporcionó 16% de rastrojo de maíz en las dietas. En el rendimiento de la canal caliente, fría y proporciones no hubo diferencias. En el tratamiento C se observo el mayor tamaño...

Concentration of trans-vaccenic and rumenic acids in the milk from grazing cows supplemented with palm oil, rice bran or whole cottonseed R. Bras. Zootec.
Castaño,Gastón Adolfo; Pabón,Martha Lucía; Carulla,Juan Evangelista.
The changes in the concentration of trans-vaccenic (C18:1t-11) and rumenic (C18:2c-9,t-11) acids in the milk from cows grazing on Pennisetum clandestinum, fed a supplement containing palm oil, rice bran or whole cottonseed were evaluated. Three supplements were assessed: one control supplement containing palm oil (C), with a low concentration of linoleic acid mainly from palm oil, and two supplements containing rice bran (RB) or whole cottonseed (CS) as the main source of linoleic acid. Six Holstein cows (4.2±1.7 years of age, 532.5±50.7 kg BW, 125±29 days in milk and a milk yield of 21.7 5.8 kg d−1; Mean±SD) were assigned to each treatment using a double 3 × 3 × 3 Latin Square Design. Compared with treatment C, the milk fat concentrations of...

Effect of dietary linoleic acid on the progression of chronic renal failure in rats BJMBR
Gregório,S.M.P.; Lemos,C.C.S.; Caldas,M.L.; Bregman,R..
The role of linoleic acid in chronic renal failure (CRF) is controversial. In the present study 21 male Wistar rats submitted to 5/6 renal mass reduction (R) and 16 normal controls (C) were fed a supplement (S) or normal (N) linoleic acid diet for 60 days starting 10 days after CRF. As expected, serum creatinine, cholesterol and triglycerides (mean ± SEM) were higher in the CRF groups compared to the C groups (P<0.05). The RS group presented lower cholesterol (84 ± 4 vs 126 ± 13 mg%) and triglyceride (88 ± 9 vs 132 ± 19 mg%) levels compared to the RN group. Proteinuria and kidney weight did not differ between CRF groups. Glomerular area increased 78% in RS and 100% in RN compared to control rats. Glomerular sclerosis index tended to be lower in RS (27%)...

Effect of nitrogen on achene protein, oil, fatty acid profile, and yield of sunflower hybrids Chilean J. Agric. Res.
Ali,Amjed; Ullah,Sami.
Seed yield and achene oil yield are the main determinants for N application rates rather than seed composition. Nitrogen plays a critical role in producing unsaturated fatty acids (oleic and linoleic acids), which are the main factors determining sunflower oil quality (Helianthus annuus L.). Studies were conducted on the effect of N fertilization on seed yield, achene oil yield, and quality parameters of sunflower hybrids for two successive years (2010 and 2011) in a split plot arrangement under a randomized complete block design. The hybrids (Hysun-33 &amp; S-278) and N levels (0, 75, 150, and 225 kg ha-1) were allotted in main and sub-plots, respectively. Increasing N levels resulted in steady increases in yield, protein contents and linoleic acid,...

Effect of temperature on polyunsaturated fatty acid accumulation in soybean seeds Braz. J. Plant Physiol.
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...

Measurement of fruit color-heterogeneity index and their relation to Jatropha curcas L., oil in Colombia Acta Agron. (Palmira)
Campuzano-Duque,Luis Fernando; Cardeño,Fernando.
Abstract Jatropha curcas L. is a wild species in the domestication process with an oil and biofuel potential use. The evolutionary-adaptive processes have conferred a reproductive mechanism based on protogyny-geitonogamy, achieving a floral asynchrony addressed to ensure the outcrossing and survival in extreme climate and soil conditions. In the wild, this plant performs a fruit heterogeneity, an unattractive attribute for harvest timing. Therefore, this research aimed to determine the number of harvest, yield and proportion, and physiological states of fruit maturity with the maximum oil quantity and quality. A randomized complete block factorial arrangement of treatments design was performed. The varieties and stages of fruit ripeness, were the factors....

Omega-3 fatty acid supplementation in horses R. Bras. Zootec.
Hess,Tanja; Ross-Jones,Trinette.
Polyunsaturated omega-3 fatty acids (n-3 PUFA) are a family of essential fatty acids with many biological activities. These fatty acids are incorporated into cell membranes, changing their structural and functional characteristics. N-3 PUFA can act by modulating inflammatory responses at different levels. Omega-3 PUFA can be converted in the body to longer-chain n-3 PUFA at a limited rate and are differently converted in body systems. It appears that when specific longer-chain n-3 PUFA are desired these need to be supplemented directly in the diet. In different species some evidence indicates a potential effect on improving insulin sensitivity. Recently, a novel class of n-3 PUFA-derived anti-inflammatory mediators have been recognized, termed E-series and...

Plasma fatty acid profile in dairy cows associated with the inclusion of annatto in their diet Animal Sciences
Lima, Clarissa Sampaio de Oliveira; Andrade, Albericio Pereira de; Magalhães, André Luiz Rodrigues; Almeida, Omer Cavalcanti de; Guido, Sebastião Inocêncio; Valença, Roberta de Lima.
The objective of this study was to evaluate the plasma lipid profile and plasma fatty acids of dairy cows receiving diets supplemented with annatto. A total of 32 Holstein cows (550 kg), distributed in a completely randomized design, were allocated to individual stalls and submitted to following treatments: C0 = no annatto; C4 = inclusion of annatto at 4 g kg-1 dry matter (DM) of diet (0.07 g bixin kg-1 diet); C5 = inclusion of annatto at 5 g kg-1 DM of diet (0.09 g bixin kg-1 diet); and C7 = inclusion of annatto at 7 g kg-1 DM of diet (0.12 g bixin kg-1 diet). Blood samples were collected via epigastric vein puncture, centrifuged, and frozen for subsequent analysis. The results indicate that the inclusion (p &gt; 0.05) of annatto does not decrease the...

Use of enzymes in diets with different percentages of added fat for broilers Arq. Bras. Med. Vet. Zootec.
Costa,F.G.P.; Morais,S.A.N.; Lima,M.R.; Souza,R.B.; Santos,T.T.; Gomes,G.A.; Pinheiro,S.G..
We assessed the extent to which the removal of fat source, and consequently its compounds, such as linoleic acid, can affect the performance of broilers. We used 600 male Cobb 500 day old chicks. The birds were distributed in a completely randomized experimental design, with five treatments and six replicates of 20 birds each. The treatments were: (T1) diet - positive control (PC), which met the nutritional needs; (T2) diet - negative control (CN), a reduction of 100kcal/kg and low linoleic acid content; (T3): diet - negative control reformulated for low linoleic acid content and a set of Quantum phytase XT and Econase XT 25 (BAL + QFit-Eco), (T4): diet - negative control reformulated, with the percentage of linoleic acid adjusted to an intermediate value...
