Four sheep cannulated in the rumen and proximal duodenum were used in a 4 × 4 cross-over design to investigate the effects of ruminal fatty acid (FA) infusion on duodenal and serum FA profiles. The diets were composed of 85.7% natural grassland hay and 8.6% concentrate supplemented with 5.7% soy oil for diet SO, 5.7% emulsified soy oil for diet ESO, 6.7% calcium salts of soy or palm FA for diets CaSSO and CaSP, respectively. Diets were formulated to be isonitrogenous and isoenergetic; total FA content in dry matter was 6.4–6.6%. Characteristics of ruminal fermentation were not affected by source or physical form of FA. The proportion of stearic acid in the duodenal flow (% of the total C18) was high compared with total diet, e.g., 49.8 vs. 3.5 and 54.3 vs. 9.4% for soy and palm diets, respectively. Ruminal biohydrogenation and unsaturated FA was lower for CaS diets than for SO and ESO diets (48.7 and 60.9 vs. 81.2 and 94.7%, for oleic and linoleic acids, respectively). As a result, trans-vaccenic acid levels in duodenal flow and serum (% or total FA) were lower for the CaS diets than for SO and ESO diets (8.3 vs. 36.0% and 0.9 vs. 7.8%, respectively). Unsaturated FA as CaS were partly protected against ruminal biohydrogenation, and can be effective in increasing intestinal absorption of unsaturated FA.

RAPD and fatty acid profiles, and α-tocoferol contents of the seeds of some Symphytum species were analyzed for their differentiation. Discriminative patterns were found in the examined species. Genotypic characteristics of three Symphytum species were experienced using 20 decamer RAPD primers. The majority of band positions varied between species. The total amplified products of 20 RAPD primers was 247 (average of 12.35 bands per primer), of which 189 bands were polymorphic, corresponding to nearly 76.1% genetic diversity. The number of bands for each RAPD primer varied from 8 (UBC320) to 18 (OPA7). The percent of polymorphic bands ranged from 45.4% (OPJ20) to 93.3% (OPA16). Major unsaturated fatty acids in the seeds were linoleic, γ-linolenic and oleic acids; α-linolenic and eicosenoic acids exhibited lower levels. Variations in quantities and total ratios of fatty acid groups, and α-tocopherol contents were also observed between the species, and the developmental stages of the seeds. Significant differences were found for the whole series of fatty acids between species, in addition to the calculated ratios ( p < 0.05). Differences were also significant for fatty acid traits between two developmental stages of the seeds of endemic S. pseudobulbosum ( p < 0.05). In some morphological descriptors of the seeds, difference was found at a significant level ( p < 0.05). Obtained data based on genetic and biochemical variations seem to be useful for molecular delimitation of Symphytum, in addition to selection of the genotypes expressing a high amount of GLA.

Specific Fatty Acid

Pollen of pecan [Carya illinoinensis (Wangenh.) K. Koch] from five protandrous and five protogynous genotypes was analyzed for germinability and fatty acid profile. Fatty acid profiles as a function of genotype were distinctive in all selections, but only three of the genotypes had fatty acid profiles that were easily distinguishable from others by canonical discriminant analysis. Specific fatty acid percentages influenced germination in some genotypes. Total saturated and unsaturated fatty acids influenced pollen germination to a greater degree than individual fatty acids. The effects of fatty acids on pollen germination of protandrous genotypes were opposite those on `Stuart', the only protogynous genotype to be influenced by fatty acid percentages.

Unsaturated fatty acids especially n-3 polyunsaturated fatty acids (PUFA) are recognised as important components of a healthy human diets and increased intake has been shown to reduce the incidence of cardiovascular diseases (BNF, 1992). These fatty acids are susceptible to oxidation and lipid oxidation in meat may adversely affect meat quality and safety. However, tissue α-tocopherol (AT) may reduce oxidative changes. In this study, the effect of increased dietary supply of AT and unsaturated fatty acids on tissue AT content, fatty acid profiles and oxidative stability of pig muscle lipid was assessed.
