Проведены сравнительные испытания применения гидрогенизированного защищенного жира, произведенного в России (опытная группа) и импортного фракционированного защищенного жира (контрольная группа). Установлено улучшение жирнокислотного состава молока в группе получавшей гидрогенизированный жир в части приближения его состава к параметрам ГОСТ Р 52253–2004 на фоне ранее использовавшегося фракционированного жира  при отсутствии ухудшения по количественным показателям молочной продуктивности и использования корма. Отмечено снижение содержания в молоке пальмитиновой кислоты в опытной группе на 1,5% относительно пограничного верхнего значения по ГОСТу, тогда как в контрольной группе содержание пальмитиновой кислоты было выше верхней границы ГОСТа (33%). По количеству стеариновой кислоты в молоке показатели после применения в опытной группе находились на уровне ГОСТа. Переваримость защищенного жира в этой группе составляла 67—70% против 69—71% в контрольной группе, что обусловлено более высоким содержанием стеариновой кислоты в гидрогенизированном защищенном жире в сравнении с импортным фракционированным (31,2% против 5,3%). Переваримость стеариновой кислоты составляла 56—65%, тогда как у пальмитиновой кислоты была на уровне 72—74%. Применение гидрогенизированных защищенных жиров может быть рекомендовано для предприятий, к молочной продукции которых предъявляются требования со стороны переработчиков по жирнокислотному составу молока. Comparative tests of the use of hydrogenated protected fat produced in Russia (experimental group) and imported fractionated protected fat (control group) were conducted. An improvement in the fatty-acid composition of milk in the group having received hydrogenated fat was found in terms of approximation of its composition to the parameters of GOST R 52253-2004 against the background of previously used fractionated fat in the absence of deterioration in quantitative indexes of milk productivity and feed use. It has been observed a decrease in the content of palmitic-acid in milk in the experimental group by 1.55% relative to the upper limit of GOST, while in the control group the content of palmitic-acid was higher than the upper limit of GOST (33%). According to the amount of stearic-acid in milk, after application in the experimental group the indexes were satisfactory the level of GOST. The digestibility of protected fat in this group was 67—70% in comparison with 69-71% in the control group, due to the higher content of stearic-acid in hydrogenated protected fat compared to imported fractionated fat (31.2% vs. 5.3%). The digestibility of stearic-acid was 56—65%, while palmitic-acid was at the level of 72—74%. The use of hydrogenated protected fats can be recommended for enterprises that have requirements of the fatty-acid composition of milk for dairy products from processing companies.

During our research we studied the fat content and fatty acid composition during the germination and sprouting periods of the most important sprouts: wheat, lentil, alfalfa, radish and sunflower seed. In this article we present our research results during this sprouting study. The concentration of the saturated fatty acids (palmitic acid, stearic acid) decreased, the concentration of the unsaturated fatty acids increased during germination, but the tendency was not so high than was published in the literature.

The Impact

Abstract. The objective of this research was to examine the impact of supplementation with magnesium oxide (MgO) on the fatty acid composition, antioxidative capacity and quality parameters, determined on 24 pork longissimus muscles (LD). Crossbred pigs equal for halothane genotypes (12 normal, nonmutant – NON, 12 heterozygous, monomutant – MON) and sex, were fed a diet supplemented with MgO (3.6 g magnesium daily) for 5 days prior to the slaughter. There was a tendency of higher intramuscular fat, a significant higher concentration of C17:0 and C18:2n-6, C22:5n-3 and the total amount of n-3 fatty acids (P < 0.05) in LD of supplemented pigs. A higher resistance to in vitro stimulation of peroxidation in muscle with MgO supplementation was observed. Increasing dietary level of MgO resulted in higher concentration (P < 0.05) of magnesium in plasma. Genotype had significant effects on some quality indicators . Pigs fed the MgO supplemented diet had higher muscle pH compared to pigs fed the control diet. Significant differences (P < 0.05) were received between control heterozygous pigs and MgO normal pigs. The LD of pigs fed diets supplemented with MgO had lower percentage of drip loss compared to pigs fed the control diet. Significant differences (P < 0.05) were found between heterozygotes control group and the other three groups. In conclusion MgO supplementation could not only improve post mortem pH rate breakdown and water holding capacity but also the antioxidant stability.

12 week feeding trial was conducted to evaluate the effect of palm oil (PO) supplementation at 0%. (control), 3% or 5% levels on carcass yields and fatty acid composition of organs of growing rabbits. Results obtained showed that palm oil supplementation did not significantly affect (P>0.05) carcass and organ yields. Percent analysis however showed that in the heart, myristic acid was highest in the control diet (78.58%), lauric acid in 3% PO (41.56%) and stearic acid in 5% PO (84.43%) groups. In the kidney, there was an increased level of palmitic (1.30-57.06%}but decreased levels of myristic (43.41 -0.51%) and oleic acids (9.26 - 8.08%). There were detectable levels of raprylic, linoleic and arachidonic acids in rabbits fed PO diets compared to none in the control group. On the other hand, there were detectable levels of stearic and lauric acids in the control group but none in the PO groups. In the liver, only lauric, stearic and myristic acids were detected, with the latter not detected in the liver of cor.trol group. Three rabbits on the control diet died as a result of septicaemia. It was concluded from this study that PO seemed to affect organ fatty acid composition but not on weight of organs. The effect on fatty acid composition was however, not consistent.

Hatching Eggs

The five groups of Pharaoh quail (100 animals per group) were formed to fulfill the tasks. Quails of the control group were fed by the standard mixed fodder for quail (DSTU 4687:2006). The bird of the research groups (I–IV) received the same feed, but with the addition of 20 g/t of vitamin E. We selected the hatching eggs after 4 weeks of feeding research fodders. Eggs were weighed and laid for incubation using the standard mode after pre-incubation storage of the eggs of the quails obtained in the peak of egg production for 5 days. On the 14th day of incubation, the eggs of the quails were divided into 5 groups. Treatment of eggs I, II and III of the test group was carried out on the 14th day of incubation, respectively, with solutions of 1% sodium hypochlorite 2% perchloric acid 0,5% hydrogen peroxide. Egg of control and IV experimental group were not subject to chemical treatment. The material for research was hatching eggs of quail, liver tissue of 14 daily embryos and 1-day quail. The fatty acid composition of the lipids of tissues and egg yolk was determined in this biological material. Analysis of methyl esters of LC was carried out on a Gas chromatograph Trace GC Ultra (USA) with a flame ionization detector. Identification of fatty acids was carried out using a standard Supelco 37 Component FAME Mix. Quantitative assessment of the spectrum of fatty acids of yolk lipids was carried out by the method of internal normalization, determining their percentage content. Ontogenetic differences in the fatty acid composition of tissues are established. Processing of the eggshell on the fourteenth day of incubation with H2O2 solution is accompanied by an increase in the proportion of stearic acid in the liver of the 1-day quail and a decrease in the proportion of Neukosatrienoic and pre-fatty acids. Treatment of the shell with sodium hypochlorite and HCl is accompanied by an increase in the proportion of stearic acid by 0.96–1.00 % and аrachinic acid, with a decrease in the proportion of gondoinic and eicosatrienic fatty acids. At the same time, when treating with HCl and sodium hypochlorite, the ratio of the sum of saturated to unsaturated fatty acids decreases by 3.2–7.9% (p<0.05). So, the established changes in the fatty acid composition of the liver one-day quail indicate a significant effect of the chemical treatment of the egg shell on the exchange of fatty acids in the embryonic period.

The research studied the effects of dietary supplementation with Camelina sativa fresh forage on the chemical and fatty acid composition of milk and Caciotta cheese, and its sensory properties. Twenty Ionica goats were randomly assigned to the following two groups (n = 10): the control received a traditional forage mixture (Avena sativa, 70%; Vicia sativa, 20%; Trifolium spp., 10%), while the experimental group was given Camelina sativa fresh forage (CAM). All of the dams grazed on pasture and received a commercial feed (500 g/head/day) at housing. The milk from the CAM group showed a higher (p < 0.05) content of dry matter, fat, lactose and concentrations of C6:0, C11:0, C14:0, C18:2 n-6, CLA and PUFA, while lower (p < 0.05) amounts of C12:0, C18:0 and saturated long chain FA (SLCFA). The Caciotta cheese from the CAM group showed a greater (p < 0.05) content of n-6 FA and n-6/n-3 ratio, although close to four, thus resulting adequate under the nutritional point of view. The overall liking, odour, taste, hardness, solubility and “goaty” flavour were better (p < 0.05) in the CAM cheeses. Further investigation would be advisable in order to evaluate the effect of feeding Camelina forage obtained from different phenological stages, and the application of ensiling techniques.

Ruminal Fluid

We evaluated the effects of a rumen-protected microencapsulated supplement from linseed oil (MO) on ruminal fluid, growth performance, meat quality, and fatty acid composition in Korean native steers. In an in vitro experiment, ruminal fluid was taken from two fistulated Holstein dairy cows. Different levels of MO (0%, 1%, 2%, 3%, and 4%) were added to the diet. In an in vivo experiment, eight steers (average body weight = 597.1 ± 50.26 kg; average age = 23.8 ± 0.12 months) were assigned to two dietary groups, no MO (control) and MO (3% MO supplementation on a DM basis), for 186 days. The in vitro study revealed that 3% MO is an optimal dose, as there were decreases in the neutral detergent fiber and acid detergent fiber digestibility at 48 h (p < 0.05). The in vivo study showed increases in the feed efficiency and average daily gain in the 3% MO group compared to the control group on days 1 to 90 (p < 0.05). Regarding meat quality, the shear force produced by the longissimus thoracis muscle in steers from the 3% MO group was lower than that produced by the control group (p < 0.05). Interestingly, in terms of the fatty acid profile, higher concentrations of C22:6n3 were demonstrated in the subcutaneous fat and higher concentrations of C18:3n3, C20:3n3, and C20:5n3 were found in the intramuscular fat from steers fed with 3% MO (p < 0.05). Our results indicate that supplementation with 3% MO supplements improves the growth performance and meat quality modulated by the omega-3 fatty acid content of meat in Korean native steers.

SummaryAberdeen Angus and Friesian cattle were reared from 4 months of age to slaughter weight at 18–24 months on either high-barley or high-hay diets. Samples of subcutaneous fat were taken by biopsy at 3 monthly intervals, and the degree of fatness of each animal was estimated ultrasonically prior to slaughter, and by visual inspection of the carcasses.The barley-fed animals gained weight more rapidly, and fattened more quickly than the hay-fed animals with the Angus being fatter than the Friesian at the same age. The percentage stearic acid (C18:0) in subcutaneous fat decreased with age and was replaced by octadecenoic acid (C18:l) and hexadecenoic acid (C16:l), these changes being more rapid in barley-fed than in hay-fed animals. At the same degree of fatness the depot fats of the Friesians were more unsaturated than those of the Angus, and in both breeds the fatter the animal the more unsaturated was its depot fat.In the hay-fed cattle the percentage C16:0 in subcutaneous fat increased during the last half of the experiment and at slaughter the percentage C16:0 was significantly higher, and C18:l significantly lower, in all depot fats compared with those of the barley-fed animals.It is concluded that the fatty acid composition of bovine depot fats is modulated by the degree of fattening, and can be affected by diet.
