The efects were studied of the quality and amount of dietary fat on the pattern of fatty acids in the lipids of the serum and certain tissues (adipose fat, perirenal fat, liver, heart, testes) of guined pigs during experimentally induced hypercholesterolemia. During 12 weeks the animals received experimental diets containg 10% or 20% of energy from animal fats (butter, lard 2:3), sunflower oil or low-erucic rapeseed oil. Two control groups were chosen, receiving diets for animals without cholesterol or with 0.1% cholesterol added. The addition of cholesterol to the diet raised the content of the essential unsaturated fatty acids and polyunsaturated fatty acids in the adipose fat and hepatic lipids, and decreased their content in myocardial lipids. In testicular lipids changes were noted in the synthesis of long-chain polyunsaturated fatty acids. The addition of vegetable fats to the diet increased the content of linoleic acid in these tissues with a simultaneous decrease of arachidonic acid synthesis. It may be supposed that there is an upper range of arachidonic acid synthesis in the lipids of the studied tissues independent of dietary EFA and PUFA value.

Polyunsaturated fatty acids (PUFAs, LA and ALA) are not synthesized in mammals in the absence of their essential fatty acid precursors. However, hibernating animals and animals sleeping through the winter need sufficiently high amounts of these acids. The Eurasian badger does not hibernate, but sleeps over winter. In the autumn the body weight of adult badgers increases even twofold, since they put on fat before the winter. Fat is deposited primarily in the subcutaneous layer of adipose tissue, and much less commonly in the muscles, liver and around the intestines. The percentage composition of fatty acids (Saturated fatty acids-SFAs, monounsaturated fatty acids-MUFAs, PUFAs) is different in particular types of tissue. The lipids isolated from depot adipose tissues (suet, subcutaneous, perirenal, periintestinal fat) are dominated by monounsaturated fatty acids (on average 41.25%), followed by saturated fatty acids (33.53%). Polyunsaturated FAs have the lowest proportion in this groups of tissues, on average 17.75% of total FAs. On the other hand, liver lipids contain over 44% PUFAs. The fatty acid composition of lipids in badgers tissue includes considerable quantities of essential unsaturated n-6 and n-3 fatty acids of great pharmacological significance.

The objective of this study was to evaluate the behaviour of fibre in the digestive tract on the basis of the passage kinetics of forage and concentrate particles in cows fed different omega-6 fatty-acid sources. The scientific hypothesis of this study was that omega-6 fatty acids do not interfere with the digestion of fibre in the diets of dairy cows. Five primiparous lactating Holstein cows were used in the experiment. The experimental diets were: control (C), ground soyabean (GS), cottonseed (CS), soyabean oil (SO), calcium salts of fatty acids (CSFA). The global mean estimates for the parameters of passage rate (γ) were 0.038 and 0.055 h–1 for forage and concentrate, respectively. The only significant effect with respect to the passage rate was a high negative correlation between the concentrate passage rate and dry matter intake. There was less undegradable neutral detergent fibre (NDF) in treatments without added lipid. Dietary supplementation with lipid sources does not alter the kinetic parameters of roughage and concentrate particle passage or in vitro NDF degradation. Sources of omega-6 fatty acids do not alter the rumen degradation and transit of fibre.

Lipid peroxidation is a process involving the oxidation of polyunsaturated fatty acids (PUFAs), which are basic components of biological membranes. Reactive electrophilic compounds are formed during lipid peroxidation, mainly α,β-unsaturated aldehydes. These compounds yield a number of adducts with DNA. Among them, propeno and substituted propano adducts of deoxyguanosine with malondialdehyde (MDA), acrolein, crotonaldehyde and etheno adducts, resulting from the reactions of DNA bases with epoxy aldehydes, are a very important group of adducts. The epoxy aldehydes are more reactive towards DNA than the parent unsaturated aldehydes. The compounds resulting from lipid peroxidation mostly react with DNA showing both genotoxic and mutagenic action; among them, 4-hydroxynonenal is the most genotoxic, while MDA is the most mutagenic. DNA damage caused by the adducts of lipid peroxidation products with DNA can be removed by the repairing action of glycosylases. The formed adducts have been hitherto analyzed using the IPPA (Imunopurification-32P-postlabelling assay) method and via gas chromatography/electron capture negtive chemical ionization/mass spectrometry (GC/EC NCI/MS). A combination of liquid chromatography with electrospray tandem mass spectrometry (LC/ES-MSMS) with labelled inner standard has mainly been used in recent years.

A comparative study of the oil yield and fatty acid composition of three Salvia species seeds collected in different locations has been conducted. Seed oil extraction was made using a Soxhlet-extractor and fatty acid analysis was undertaken using a GC-FID. The effect of the collecting site on oil yield, as well as the content of individual fatty acid and total fatty acid and fatty acid content was significant. Seed oil yield varied from 14.94 to 22.83% and the total fatty acids ranged from 67.36 to 82.49 mg/g DW. α-Linolenic (24.02-49.19%), linoleic (20.13-42.88%), oleic (12.97-17.81%) and palmitic (8.37-16.63%) acids were the most abundant fatty acids in all analyzed samples. α-Linolenic acid was found to be the major fatty acid in S. verbenaca and S. officinalis species, however, S. aegyptiaca was characterized by the prevalence of linoleic acid. Among the unsaturated fatty acids, which were represented in all samples in high amounts (78.16-89.34%), the polyunsaturated fatty acids (α-linolenic and linoleic acids) showed important levels ranging from 63.09 to 74.71%. Seeds of S. verbenaca were the richest in polyunsaturated fatty acids.

The aim of the study was to evaluate physical traits and fatty acids profile of ostrich meat enriched in n3 fatty acids as affected by refrigerated storage (for 14 days) and type of packaging (VAC vs. skin-packaging – SP). During refrigerated storage time drip loss after 7 days was significantly (P<0.001) higher in VAC as compared to SP samples. No significant differences in the SFA content in meat during storage in both types of packaging types recorded. Although there were no significant differences (P=0.067), a tendency for higher MUFA values was observed during storage in VAC packed meat. A significant decrease (P<0.05) in the content of PUFA after 7 and 14 days of storage was also observed in VAC packed meat as compared to fresh meat, whereas, when skin packaging was used, no differences in the PUFA concentration were found. Considering this, the SP can be recommended packaging for ostrich meat industry.

The aim of this study was to determine the effect of fish-based feed materials, as a source of readily available protein contained in fish broth and essential polyunsaturated fatty acids (PUFAs) found in fish oil, on the health of piglets and rearing results. The experiment was conducted on a commercial pig fattening farm. The study involved a total of 80 weaners with an approximate body weight of 15 kg. The experiment was carried out over a period of 40 days. Feed samples were subjected to laboratory analyses. Blood samples were collected from experimental group animals to determine serum biochemical and immunological parameters. The body weight gains of weaners, mortality rates and average feed intake per animal were calculated for the entire experimental period. The addition of fish broth and fish oil significantly improved the n3:n6 fatty acid ratio in diets. The presence of EPA and DHA in the experimental diet could have had a positive health effect on piglets, comparable with that exerted by therapeutic doses of zinc often administered to pigs of this age group. During the experiment, feed conversion ratio (FCR) gain was considerably reduced in the experimental group, with similar daily gains in the control and experimental group.

In a randomly selected group of 444 men and women divided into three age groups: 35-44 years, 45-64 years and 55-64 years, the composition of fatty acids in total serum lipids was determined by gas chromatography, with particular reference to EFA (linoleic, linolenic, arachidonic acids) and the P:S index. The results showed that the levels of EFA and PUFA (all unsaturated fatty acids) were significantly higher in women than in men in this population. The mean EFA value in women was 31.3% and in men 29.3%. The PUFA level was 33.7% and 31.7% respectively. Similarly, the P:S index in women was significantly higher - 1.02 than in men - 0.94. In the light of these results, it may be assumed, that the serum EFA level in the studied subjects points to an intake of those acids covering up to 3% of the total energy of the daily food ration.
