“…3.0 g/kg dietary dry mater was reported by Shi et al [ 292 ]. Using the rumen simulation technique, it was observed that nanoemulsified soyabean oil modulated the PUFAs proportions in ruminal cultures, which was reflected in markedly increased proportions of oleic acid, α-LLA, and α-LNA in the fermentation fluid without any negative effect on rumen fermentation parameters [ 293 ].…”

Dietary supplements and foods for special medical purposes are special medical products classified according to the legal basis. They are regulated, for example, by the European Food Safety Authority and the U.S. Food and Drug Administration, as well as by various national regulations issued most frequently by the Ministry of Health and/or the Ministry of Agriculture of particular countries around the world. They constitute a concentrated source of vitamins, minerals, polyunsaturated fatty acids and antioxidants or other compounds with a nutritional or physiological effect contained in the food/feed, alone or in combination, intended for direct consumption in small measured amounts. As nanotechnology provides “a new dimension” accompanied with new or modified properties conferred to many current materials, it is widely used for the production of a new generation of drug formulations, and it is also used in the food industry and even in various types of nutritional supplements. These nanoformulations of supplements are being prepared especially with the purpose to improve bioavailability, protect active ingredients against degradation, or reduce side effects. This contribution comprehensively summarizes the current state of the research focused on nanoformulated human and veterinary dietary supplements, nutraceuticals, and functional foods for special medical purposes, their particular applications in various food products and drinks as well as the most important related guidelines, regulations and directives.

“…However, negative effect of oil supplements added to ruminants diets depends on various factors, like the type and form of diet, the amount of supplements or additives used etc. It was shown that the same amount of added oils do not disturb rumen fermentation and positively influence milk production and FA composition (Cieślak et al, 2015;El-Sherbiny et al, 2016). The values of NDF and acid detergent fibre (ADF) varied among GLA-enriched PCS (Table 2).…”

“…The results were similar to those of Adeyemi et al (2015a), supplementation of 8% combination of canola oil (80%) with palm oil (20%) has a rumen pH of 6.71 and supplementation of 8% carotino oil produces a rumen ph value of 6.95. El-Sherbiny et al (2016) stated that 5% supplementation of several oil nanoemulsions including soybean oil, fish oil and a combination of both had an average pH of 6.83. The pH value was not different because it was assumed that the composition of the treatment ration was the same, so that the difference in the speed of VFA production was not prominent in terms of DMD and OMD which were almost the same (Table 3).…”

“…According to O'Brien et al (2014), that linoleic and linolenic acid significantly (P<0.01) decreased the production of acetate, linoleic and linolenic content in oil could reduce the activity of methanogenic bacteria. El-Sherbiny et al (2016) stated that supplementation of nanoencapsulation of fish oil and soybean oil can reduce total VFA and acetate production. The existence of polyunsaturated fatty acids in this study led to an emphasis on the activity of methanogenic bacteria in using H2 for methane production, so that an increase in hydrogen accumulation and cause a reaction change from pyruvate to lactate.…”

This study was examines the effect of oil (oil palm and corn) combination with the level of protection (total or partial) on feed fermentability, methane production and energy efficiency with in vitro techniques. The experiment was designed using a factorial pattern 2x2, factor A = type of oil (corn and palm) and factor B = oil protection level (total and partial), each treatment combination was repeated 4 times. Data was processed by analyzing various factorial patterns in a randomized block design and if there was an influence between treatments performed by the Dunca test. The results showed that there was no interaction effect (P>0.05) between the types of oil with the level of protection in all parameters, except NH3. Supplementation of palm oil produces total volatyle fatty acids (VFA), acetate and methane (CH4) production higher than corn oil (P<0.05), but the efficiency of converting hexose energy to VFA (ECH) was lower (P<0.05) (76.09 vs 77.80%). Supplementation of total protected oil decreased in the protozoa population, resulting in higher dry matter digestibility (DMD) and organic matter digestibility (OMD), but lower ECH yield compared to partial protected oil supplementation (P<0.05), ie 76.68 vs 77.22%. The conclusions of the study are corn oil produce of ECH higher than palm oil. Partial protection produce better feed fermentability and increasing energy efficiency in the form of decreasing A/P ratio and methane production.
