Comparação do desempenho de leitões refugos criados em aleitamento natural e em...

TCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências Agrárias. Curso de Zootecnia.; A suinocultura vem apresentando dados crescentes de leitões nascidos por leitegada. Enquanto que na década de 1990 o número total de leitões nascidos em plantéis com excelente material genético limitava-se, em média, a 10 a 12 leitões, verifica-se, atualmente, o nascimento freqüente de leitegadas com 15 e...

Fatty acids profile of selected Artemisia spp. plants: health promotion

In the present study we report the fatty acids profile of thirteen species of Artemisia, a hardy herb or shrub, analyzed by gas chromatography connected to a mass detector (GC-MS) for their nutritional value and their potential exploitation as a new source of essential fatty acids. Total lipids content ranged from 3.31 ± 0.19 to 17.78 ± 0.27 mg/g (fresh weight). The three most abundant fatty acids were C16:0, C...

Omega-3 fatty acid desaturase genes isolated from Purslane (Portulaca oleracea ...

Two full-length cDNA clones PoleFAD7 and PoleFAD8, encoding plastidial omega-3 fatty acid desaturases were isolated from purslane (Portulaca oleracea). The encoded enzymes convert linoleic to alpha-linolenic acid (C18:3n-3). Three histidine clusters characteristic of fatty acid desaturases, a putative chloroplast transit peptide in the N-terminal, and three putative transmembrane domains were identified in the ...

Molecular cloning and expression analysis of three omega-6 desaturase genes fro...

Two full-length cDNA clones of PoleFAD2 and one full-length cDNA clone of PoleFAD6, encoding omega-6 fatty acid desaturases, the key enzymes for the conversion of oleic into linoleic acid, were isolated from purslane (Portulaca oleracea L.) leaves and seeds. The deduced amino acid sequence of both isoforms of PoleFAD2 showed higher similarities to other microsomal omega-6 desaturases then to PoleFAD6 or other p...

Growth conditions, omega - 3 fatty acid concentrations and gene expression of f...

A beldroega (Portulaca oleracea), foi seleccionada como sistema de estudo para este trabalho com base no seu elevado valor nutricional, em particular no conteúdo en ácidos gordos polinsaturados, e a tolerância demonstrada à seca e salinidade. O trabalho de investigação aqui desenvolvido pode ser dividido em quatro pontos essenciais: (i) o estudo dos efeitos da salinidade no valor nutricional da beldroega; (ii) ...

Effects of salt stress on purslane (Portulaca oleracea) nutrition

The objective of this study was to determine the influence of saline stress on the chemical composition of purslane (Portulaca oleracea), in particular the mineral composition. Four salinity levels were investigated using irrigation solutions with electrical conductivity values of 0.8, 6.8, 12.8 and 24.2 dS m−1 and two planting dates (May and July) were tested. Samples of full-grown leaf and stems of purslane w...
