The study aimed at determining fatty acid (FA) profiles of meat of seasonally fed slow-growing rabbits in relation to lipid composition of feeds and their intake. In each season, 21 weaned male rabbits (Popielno White breed) were assigned into two homogenous groups: the control (C, n=7) and seasonally fed - summer (S, n=14) or winter (W, n=14). Meat lipid, MUFA and PUFA contents were significantly higher in the S and C groups, most likely due to a higher lipid intake, while S-rabbits had two-fold higher n-3 PUFA contents than C-rabbits. This resulted in a better thrombogenic index in S- rather than in C-rabbits, similarly as it was the case for the hypocholesterolemic/ hypercholesterolemic (H/H) ratio. In relation to the other groups myristic and palmitic acid contents in meat were greater in W-rabbits due to a higher SFA intake. As compared with the C diet, seasonal diets were associated with a higher proportion of n-3 PUFA in meat. This resulted in an improvement of the n-6/n-3 ratio (3.62 on average) in meat from seasonally fed rabbits. Both seasonal diets also increased the content of odd-numbered and branched-chain acids (OBCFA; twofold greater than in the C group). S-rabbits had greater daily body mass gains and were heavier than the W-rabbits. The content of palmitooleic acid (C16:1 n-7) in meat was high irrespective of the diet. Feeding strategies associated with outdoor rearing, adopted in small farms, favour local rabbit populations. Thus, it is recommended to promote native, slow-growing rabbit breeds, a source of valuable nutrients.

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 aim of the study was to evaluate the fatty acids composition of storage fat of slaughter horses. Samples of cervical and peri-intestinal fat taken from horses of different genders and weights in a slaughterhouse were used as the study material. The fat was esterified by the method described by Peisker. Separation and analysis of the fatty acids was conducted by gas chromatography with a flame ionisation detector. The samples were found to contain fatty acids with chains of 14 to 20 carbon atoms, mainly palmitic, myristic, oleinic, palmitoleic and linolenic acids. Small differences were found between groups of horses classed by body weight. The experiment confirmed that the composition of horse fat in terms of mono- and polyunsaturated acid content is interesting from a nutritional point of view. Cervical fat contained average 49% of monounsaturated fatty acids and polyunsaturated fatty acids in horses in mass to 550 kg and mass above 550 kg 12.57% and 10.79%, respectively.

Fatty acid (FA) composition of eggs from nine poultry species was determined chromatographically.Twenty six FAs were determined in the lipid composition of eggs. Monounsaturated fatty acids (MUFA) were found in higher amounts than saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) in egg yolks. Oleic acid (C18:1 n9) was the major MUFA in egg yolk and, palmitic acid (C16:0) was the major SFA in nine of all different originated eggs. Linoleic acid (C18:2 n6),arachidonic acid (C20:4 n6) and linolenic acid (C18:3 n3), reached the highest levels among the PUFAs. SFA/PUFA ratios were found to be 0.97, 2.51, 2.20, 1.46, 1.67, 1.40, 1.96, 1.27, and 1.34 in chicken, goose, duck, turkey, peacock, guinea fowl, pheasant, quail and partridge, respectively.Eggs of all nine species were found valuable for human consumption as fatty acids source, but the chicken’s egg occured to be the most beneficial to human health according to its highest omega 6 fatty acid (29.8%), highest PUFA / MUFA ratio (0.80) and lowest of SFA / PUFA ratio (0.97).

In nandu eggs (n = 9) the mean cholesterol content of yolk was 16.41 mg/g. In a sum of 21 fatty AIDS determined, the considerable share – 33.55% – of polyunsaturated acids was found, and especially of linolenic (C18:3) – 4.95% and arachidonic (C20:4) – 7.59%, both considered essential in human nutrition. It is concluded that nandu eggs are of considerable dietetic value.

Changes in cellular fatty acid composition during naphthalene degradation, at the concentrations of 0.5 g l⁻¹ or 1.0 g l⁻¹, by Pseudomonas sp. JS150 were investigated. In response to naphthalene exposure an increase in saturated/unsaturated ratio was observed. Additionally, the dynamic changes involved alterations in the contents of hydroxy, cyclopropane and branched fatty acids. Among the classes of fatty acids tested the most noticeable changes in the abundance of cyclopropane fatty acids were observed. Since day 4 of incubation these fatty acids were not dectected in bacterial cells growing on naphthalene. In contrast, markedly increased in the percentage of hydroxy fatty acids over time was observed. However, the proportions of saturated straight-chain and branched fatty acids did not change such significantly.

Culled breeding ostriches weighing 130-160 kg yield about 25 kg fat tissue that could possibly be used for supplementing human and animal diet. Cholesterol content of breast fat – 80 mg/100 g tissue – from the breeding ostrich females (n = 6) culled and slaughtered at the age of five years appeared similar to that reported of beef and lamb adipose tissue. In a sum of 17 fatty acids (FA) determined, the mono- and polyunsaturated FA accounted for 37.51 and 38.84%, respectively. The ratio polyunsaturated/saturated FA in breast fat of culled breeding ostrich females appeared higher than reported for other avian species.It is concluded that fat from culled breeding ostriches can be used as an additive to human or animal diet, thus allowing the farmer to gain more from ostrich production. Further research is needed on composition and properties of adipose tissue of ostriches, including slaughter, as well as breeding birds culled at different ages.

The purpose of the present study was to determine the influence of animal and plant lipids (cod-liver, soybean and sunflower-seed oil, sunflower-seed and tallow fatty acids, sunflower-seed lecithin) on the growth and chemical and fatty acid composition of carp, Cyprinus carpio L. Eight isocaloric diets that were processed into granules and distributed in three experiments were used. The nutritive lipid sources that were a component of the carp diets stimulated growth, protein absorption, and the retention of fats and protein. The fatty acids extracted from the carp in the 2+ age group were either oleic-linoleic-palmitic or oleic-palmitic-linoleic. The individual fatty acid profile was influenced by the composition of the lipid sources.

Extensive research have indicated that commercial conjugated linoleic acid (CLA), fed to laboratory animals, showed several health-related properties. The objective of this study was to assess the effect of CLA on serum lipid profile, plasma malondialdehyde and liver fatty acids profile in Wistar rats fed for 23 d. The experimental diets were: I-AIN-93G - control (C), II- AIN-93G diet + 1.0% CLA. The CLA oil contained 600 g CLA/kg, with equal representation of cis-9,trans-11 and trans-10,cis-12 CLA isomers. The experimental treatments had no effect on rats body weight, total cholesterol, HDL, LDL+VLDL and malondialdehyde. The triacylglycerol (TG) was significantly decreased after CLA supplementation. Liver weight, fat and histology were unchanged in CLA group. Liver cholesterol was insignificantly decreased in CLA diet. Dietary treatments had significant effects of on proportions of SFA and MUFA and PUFA in liver. In conclusion, CLA decreases serum TG. Additionally, liver fat composition were changed after CLA supplementation
