It is well established that the fatty acid combustion of adipose issue in pigs (non-ruminants) may be manipulated by changes in the fatty acid profile of the diets. The objective of this program of work was to quantify the responses of adipose depots of finishing pigs to changes in the level and profile of dietary fatty acids and to relate these changes to the sensory quality of meat as determined by taste panel.

And Function

Almost 50% of infertility cases are associated with human male infertility. The sperm membrane is a key structure influencing sperm morphology and function in normal and pathological conditions. The fatty acid profile determines the performance not only of sperm motility but also of acrosomal reaction and sperm-oocyte fusion. This review presents available knowledge on the role of fatty acid composition in human sperm and spermatogenesis and discusses the influence of dietary fatty acids on the sperm fatty acid profile. Recent studies in biological sciences and clinical researches in this field are also reported. The topic object of this review has potential application in medicine by identifying potential causes of infertility.

Abstract Objective To elucidate whether women at risk of gestational diabetes mellitus (GDM) have a unique fatty acid profile compared to women considered normal healthy controls (NHC). Methods Three hundred pregnant women were randomized to a control group (NHC) (n = 50) and to one of three high risk groups (n = 250), one of which was GDM (n = 50). At recruitment participants’ booking bloods were taken and analyzed for lipid profiles. The GDM group’s fatty acid profile is reported here. Results GDM women compared to NHC had elevated levels of omega 6 (n-6) fatty acids compared to omega 3 (n-3) fatty acids (p = 0.01), of linoleic acid (LA) to docosahexaenoic acid (DHA) p = 0.001, sequentially distorted levels of n-6 fatty acids LA and arachidonic acid (ArA) p = 0.035, as well as significantly depressed levels of n-3 DHA (p = 0.01). Conclusion This paper shows that GDM women have a unique fatty acid profile with elevated levels of n-6 fats, depressed levels of n-3 fats and an abnormal pattern of sequential n-6 metabolism. This profile probably results from a combination of factors including underexpression and or poor utilization of desaturase enzymes, suboptimal dietary fatty acids intake, poor micronutrient status or dysbiosis of the microbiome. These results help inform development of a clinical predictive tool.

AbstractThe metabolic pathways of dietary fatty acids were studied in rabbits by analysing the fatty acid profile of different tissues (liver, perirenal fat,longissimus lumborummuscle). Four groups of 24 hybrid males each were assigned to four semi-purified diets, varying in the source oflipids which differed in n-3/n-6 ratios: 180 g/kg sunflower (S), 80 g/kg flaxseed + 90 g/kg sunflower (SF), 160 g/kg flaxseed (F) and 60 g/kg fish oil (FI). The liver showed a very important rôle in fatty acid syntheses and was the tissue richest in long-chain (≥20 C) polyunsaturated fatty acids (LCP) of n-3 and n-6 series. The S diet gave the highest mono-unsaturated fatty acids and n-6 LCP (respectively, 201·9 and 384·9 g/kg,P< 0·01) also showing a clear antagonism v. n-3 LCP; the FI diet determined the highest enrichment of n-3 LCP (179·5 g/kg,P< 0·01). a-linolenic acid was efficiently converted into n-3 LCP mainly when п-ЗІп-6 ratio was high (Σn-3/С20: 4n-6: 2·74 and 3.61,P< 0·01 in flaxseed and fish-oil diet, respectively). The same trend occurred in the muscle but in a less consistent way. The adipose tissue more closely reflected the composition of the dietary fatty acids, showing variations mainly concerning polyunsaturated fatty acids (S diet), and LCP n-3 (FI diet: 44·9 g/kg,P< 0·01). Results showed the possibility of modifying the fatty acid profile of rabbit meat by dietary means and that the n-3/n-6 ratio of the food is crucial in regulating the relative presence of LCP n-3 or n-6 in meat products.

The objective of this study was to determine the chemical composition, fatty acid profile, and values of healthy indices of milk from a specialized farm of Polish Coldblood mares of different ages, birth orders, and lactation stages. Milk samples (n = 48) were collected for analysis in weeks 10, 15, and 25 of lactation from mares aged between five and 14 years. The study showed that the stage of lactation has a significant effect on the fatty acid (FA) profile of the milk produced on the farm. The highest concentration of monounsaturated and polyunsaturated FAs was found in milk produced from the 15th week of lactation. The milk was also characterized by low values of atherogenic and thrombogenic indices, which indicate the health benefits of milk with respect to the content of fatty acids and their potential to prevent or cause atherosclerosis and thrombosis. The study also found a significant correlation between the number of foalings (birth order), the fatty acid profile, and atherogenic index of milk produced on the farm. The findings from the study indicate that it is possible to modify the fatty acid profile of bulk tank milk through appropriate management of the age structure of the herd of mares. To confirm this dependence, the study will be continued on a larger group of mares.
