Modified Diatomite

The article presents the results of studying the effect of modified diatomite as part of a complex additive at the ratio of saturated and unsaturated fatty acids in cow’s milk. Production and physiological tests were carried out on the basis of a dairy farm LLC “Agrofirma Tetyushskoe” in the Ulyanovsk region on black-and-white cows of 2...3 lactation. For the physiological experiment, animals were selected by the method of analogues by live weight, number and month of lactation, pregnancy, and physiological state. The complex additive included modified diatomite, diacetophenonyl selenide containing organic selenium (DAFS), sunflower oil, and feed yeast. Additive based on 250 g/head/day mixed with feed once a day was administered in the diet of animals of the experimental group, the other group was a control and received no additive. The additive had an effect on the fatty acid composition of milk and contributed to an increase in the fraction of saturated fatty acids with a short chain. In the fat fraction, the amount of saturated short-chain fatty acids increases by 4.0% due to an increase in the content of capric (by 6.7%), lauric (by 12.3%, P<0.05), myristic (by 13.3%, P<0.05), palmitic (by 17.1%, P<0.05), which is a positive factor and indicates an active synthesis of volatile fatty acids, primarily acetate and 3-hydroxybutyrate. At the same time, there was a sharp decline in the content of stearic (27.3%, P<0.05) and arachinic (27.6%, P<0.05) acids. The milk of cows in the experimental group showed a decrease in the level of monounsaturated fatty acids by 7.4%.

Positive Effect

During its 132-year production, the characteristics of Livno cheesechanged, first because of the transition from sheep to cow’s milk, or their mixture.Livno cheese is specific primarly due to the presence of a specific plant cover inmountain area, climatic conditions and milk of autochthonous sheep. The purposeof this work is to determine the fatty acid composition of Livno cheese, with specialreference to the contenct of bioactive components that have a positive effect onhuman health, and to tracking any changes in their content depending on thesampling or feeding period. For the production of Livno cheese, which was sampledafter 90 days of ripening at ambient conditions, sheep’s milk was used, mentioningthat the cow’s milk was added in proportion (80:20), which is commonly used in thetraditional production of this cheese. Samples were analyzed by gas chromatographyin As Vitas laboratory in Oslo Innovation Center, according to the proceduredescribed in Luna and al. (2005). A total of 24 fatty acids were determined during thethree sampling periods (July, August and September) In cheese samples, saturatedfatty acid content (SFAs) was higher in relation to monounsaturated(MUFAs) andpolyunsaturated (PUFAs) fatty acids. The fatty acid composition of the tested cheesesamples is specific, because it contains fatty acids which have been proven to havean extremely beneficial effect on human health.

Introduction. There are several important aspects requiring a control of fatty acid composition in drinking milk distributed across the retail stores: milk is one of the main consumer products; fatty acids are the main energy substrates, involved in the synthesis of cellular structural components, whereas their interaction might impact the intensity of body growth and development; the fatty acid composition of milk varies depending on the diet and the animal's specific physiological state; in case of udder diseases, a change milk composition may occur; prevention of product counterfeiting distributed across  the retail stores. Material and methods. The present research examined milk samples from five dairy producers that distribute their products across the retailing chains in Kyiv. Milk samples were collected to determine the fatty acid composition. Milk fat was extracted following the Folch method. The milk fatty acid content assessment was carried out by gas chromatography. Results. 20 fatty acids were identified in the tested milk samples. A higher level of saturated fatty acids was recorded in milk from "Ferma" and "Selyanskoye for kids" dairy producers. The highest content of unsaturated fatty acids was registered in products of “Ukrainskoe” and “Molokia” dairy trademarks. Conclusions. The fatty acid composition of the drinking cow’s milk distributed across trading networks in Kiev was found to be heterogeneous, by differing in the content of both long-chain saturated fatty acids and unsaturated fatty acids.

Affecting Factors

The tissues of animals for food use have come to be associated with a predominance of saturated and monounsaturated fatty acids, the result of which has been to contribute to the perceived human dietary imbalance of fatty acids. The fact that porcine tissues assume a fatty acid composition similar to that of the respective diet has enabled the composition to be altered with respect to human dietary needs (Morgan et al, 1992). The fatty acid compositions of rapeseed and fish oils are characterised by a number of factors of relevance to human health recommendations (BNF, 1992). Thus, rapeseed oil contains a low content of saturates, a moderate content of linoleic acid and a high content of α-linolenic acid whilst fish oil contains high levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Although benefiting the nutritional value of meat/fat, the feeding of increased levels of highly polyunsaturated fatty acids has the potential, in theory at least, of adversely affecting organoleptic and various physical properties. Such adverse effects could be manifested during and/or after the preparation and cooking of the meat or meat products at which times the oxidative degradation of fatty acids is maximised. The inclusion of dietary vitamin E has a range of beneficial effects on meat quality principally due to its antioxidant effects. The present experiment was an attempt to optimise the fatty acid composition of pork and pork products for human health purposes whilst not adversely affecting factors controlling consumer acceptability.

Long Chain

The benefits of long chain polyunsaturated fatty acids (PUFA) to human health, especially those of the n-3 series are now widely recognised. In a previous experiment (Wachira et al. 1998) supplementing diets with whole linseed or fish oil increased n-3 fatty acid levels in lamb muscle. To raise these further the whole linseed can be treated with formaldehyde to increase protection in the rumen. Dietary antioxidants such as vitamin E can control lipid oxidation but information on their effects on lamb performance and fatty acid composition is limited. The current experiments investigated the effects of different dietary PUFA sources and vitamin E levels on growth and fatty acid composition in two sheep breeds. Detailed results of the effects of vitamin E are presented in the accompanying abstract by Enser et al.
