The article presents the research results of the effect of activated diatomite as part of a complex supplement on the composition and ratio of saturated and unsaturated fatty acids in cow's milk. The experiments were carried out in a dairy farm on black-and-white cows. The additive includes a carrieractivated diatomite; fillers are DAPS-organic selenium, sunflower oil and feed yeast and diatomite crumbs. The supplement was included in the diet of cows at the rate of 2% of the dry matter of the diet once a day. The control group did not receive the supplement. The positive effect of the use of the additive on the composition of fatty acids in cow's milk was established. There was an increase in the fraction of saturated fatty acids, which indicates an increase in volatile fatty acids: acetate and 3-hydroxybutyrate. The use of a complex supplement based on activated diatomite contributed to an increase in concentration of capric, lauric, myristic, palmitic and margarine fatty acids. The use of additives for dairy cows helps to increase their productivity, improve the quality of milk composition due to the intensive conversion of feed nutrients.

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.

Maternal Undernutrition

A close link between intrauterine growth restriction and development of chronic adult diseases such as obesity, diabetes, and hypertension has been established both in humans and animals. Modification of growth velocity during the early postnatal period (i.e., lactation) may also sensitize to the development of metabolic syndrome in adulthood. This suggests that milk composition may have long-lasting programming/deprogramming metabolic effects in the offspring. We therefore assess the effects of maternal perinatal denutrition on breast milk composition in a food-restricted 50% (FR50) rat model. Monosaccharides and fatty acids were characterized by gas chromatography, and proteins were profiled by surface-enhanced laser desorption/ionization-time-of-flight analysis in milk samples from FR50 and control rat dams. Milk analysis of FR50 rats demonstrated that maternal undernutrition decreases lactose concentration and modulates lipid profile at postnatal day 10 by increasing the unsaturated fatty acids/saturated fatty acids and diminishes serotransferrin levels at postnatal day 21. Our data indicate that maternal perinatal undernutrition modifies milk composition both quantitatively and qualitatively. These modifications by maternal nutrition open new perspectives to identify molecules that could be used in artificial milk to protect from the subsequent development of metabolic diseases.

Rayeb milk (bio-stirred yogurt) samples were prepared from cow milk sesame milk or cow and sesame milk mixture (1:1) with or without adding sucrose (5%), honey (5%), fructose (2.5%) and sorbitol (1.5%) and using ABT-5 culture. Results showed levels of saturated fatty acids (SFA), short chain fatty acids (SCFA) and medium chain fatty acids (MCFA were lower whereas values of unsaturated fatty acids (USFA), monounsaturated fatty acids (MUSFA), polyunsaturated fatty acids (PUSFA) and long chain fatty acids (LCFA) were higher in sesame milk Rayeb than that of Rayeb manufactured from cow milk. Rayeb made from cow and sesame mixture had higher levels of antioxidant activity than Rayeb prepared from cow milk or sesame milk. The acidity, total solids and total volatile fatty acids values of Rayeb milk treatments contained sweeteners were higher than that of control. The addition of sweeteners decreased SFA, SCFA and MCFA and increased USFA, MUSFA, PUSFA, LCFA and antioxidant activity values of Rayeb milk. Essential fatty acids, linoleic acid (omega-6), α-linolenic acid (omega-3) and oleic acid (omega-9) greatly increased in Rayeb made from cow and sesame milk mixture. Adding sweeteners had the same effect. Fortification of Rayeb milk with sweeteners highly improved the smell, taste, mouth feel, texture and body evaluation scores.

The aim of this paper is to determine nutritive, functional, microbiological and sensory properties of probiotic beverages produced from different volume ratios of cow's milk and soy beverage (25:75, 50:50 and 75:25). Pure cow’s milk and soy beverage served as control samples. Fermentation was performed at 43 °C by a combined culture consisting of the probiotic strain Lactobacillus acidophilus La5 and yoghurt culture. Viable counts of La5 strain in the produced beverages ranged from 7.52 to 8.20 log CFU/mL, which is above the probiotic minimum (106 CFU/mL). Lactic acid was the most prevalent organic acid in all samples (660.1 to 1003.0 mg/100 mL). The fatty acid profiles of fermented beverages were as follows: the mass fraction of saturated fatty acids was 22.2–82.7 %, of unsaturated fatty acids 22.3–77.8 % and of polyunsaturated fatty acids 15.5–65.9 %. The main soy sugars were transformed well (80 % stachyose and 50 % raffinose conversion) into lactic acid during fermentation. Functional probiotic beverages were successfully produced from different volume ratios of cow's milk and soy beverage by L. acidophilus La5 and yoghurt culture. Mixing cow's milk with soy beverage significantly improved the sensory properties of the product, especially its smell, taste and colour. The acceptability test showed good acceptance by potential consumers of all fermented beverage samples except for the sample made from 100 % soy beverage. In the end, the obtained results represent a good basis for optimisation of the ideal volume ratios of cow's milk and soy beverage for production of fermented beverages characterised by good viability of probiotic bacteria as well as by good functional, nutritive and sensory characteristics.

Produce and compare soft cheese with potential benefits of human health from Egyptian buffalo's and cow's milk was studied. Eight Egyptian lactating buffalos and cows were fed a total mixed ration supplemented with either 0% oil (CD), 2% flaxseed oil (DFO), 2% soybean oil (DSO), or 2% of their mixture (1:1, DFSO) according to a double 4 x 4 Latin Square design. Milk yield was similar between buffalo's diets but was higher in cows fed a DFO, DSO or DFSO resulting in 11.15, 8.21% or 8.97% increases compared with the control diet, respectively. Milk composition was not significantly affected in both buffalos and cows fed diets. The DFO, DSO or DFSO displayed decreased short-chain fatty acids, especially DSO and DFSO (3.73 and 3.33%, respectively) when compared to CD for buffalo milk (6.32%). The DSO and DFSO were  more effective for increasing unsaturated fatty acids followed by the DFSO in buffalo's milk fat (42.31 and 41.90 %), whereas DFO and DFSO were more effective in cow's milk fat (39.67 and 39.84%), respectively. DFO, DSO or DFSO had no significant effect on the yield, composition and sensory properties of resultant soft cheese compared to the CD for both lactating cows and buffalos. During storage, a diet rich in unsaturated fatty acids enhances protein proteolysis and antioxidant activity of soft cheese during storage compared to the CD especially for soft cheese produced from buffalo's milk.

Abstract. Three different dietary doses of Lippia citriodora natural extract were tested in order to verify their effect on productive performance and the meat quality of intensively-reared hare (Lepus europaeus Pall.). The 240 day-trial was conducted on 20 male hares, divided into 4 homogeneous groups of 5 animals each. A control group received a basal diet without any supplementation, and the other three experimental groups received a natural extract of Lippia citriodora, titrated in verbascoside, in the following amounts: 1 g, 1.5 g and 2 g of natural extract/kg feed in the low (LNE), medium (MNE), and high natural extract (HNE) groups, respectively. Natural extract enhanced the quality of the meat: there was a significant decrease (P<0.05) in saturated fatty acids and a significant increase (P<0.05) in mono- and poly-unsaturated fatty acids. The oxidative stability of the meat improved, thus highlighting a possible link between the decrease (P<0.05) in TBARS values and an increase (P<0.05) in lipid vitamin content. The cholesterol content of the meat decreased markedly (P<0.01) after the dietary verbascoside treatment, thus improving the health benefits of the meat. These results clearly show the important role of Lippia citriodora extract, titrated in verbascoside, in improving the quality of the meat of intensively-reared hares. In addition the present paper underlines how the use of natural antioxidant in the animal feeding system may provide healthier and low-oxidized products to the final consumer.

Diet Supplementation

The study was designed to evaluate the effect of diet supplementation with linseed on the carcass characteristics, meat quality and oxidative stability as well as the composition of the fatty acids in M. longissimus lumborum et thoracis (MLLT) and the backfat of fattening gilts. A total of 40 animals were used, 20 in the experimental and 20 in the control group. The results indicate that gilts fed with the control feed mixture (C) showed a higher (P &lt; 0.05) content of intramuscular fat and backfat as compared to the experimentaL group (L) of gilts. A higher drip loss (P &lt; 0.001) was recorded in the L group as same as higher pH<sub>45</sub> and pH<sub>24</sub> values (P &lt; 0.01). The fatty acid profile analysis in the MLLT showed that the content of the MUFA (monounsaturated fatty acids) was lower (P &lt; 0.01) in the L group than in the C group of the animals and also showed a higher (P &lt; 0.01) content of the PUFA (polyunsaturated fatty acids) in the L group. The content of the n-6 and n-3 PUFA was higher (P &lt; 0.001) in the L group. The ratio of the n-6/n-3 PUFA was significantly lower (P &lt; 0.001) in the L group. The PUFA/SFA (saturated fatty acids) ratio was more favourable in the L group of gilts (P &lt; 0.01). The results of the fatty acid profile analysis in the backfat proved the higher (P &lt; 0.05) content of the UFA (unsaturated fatty acids) in the L group, while the content of the MUFA was lower (P &lt; 0.001) in the L group. The total content of the SFA was lower (P &lt; 0.05) in the L group. A higher content of the PUFA (P &lt; 0.001) in the backfat was recorded in the L group than in the C group and the content of the n-3 PUFA was higher (P &lt; 0.001) in the L group. The ratio of the n-6/n-3 PUFA was more favourable (P &lt; 0.001) in the L group than in the C group. Also, the PUFA/SFA ratio was higher (P &lt; 0.001) in the L group.

The aim of this study was to determine the genetic effect of cow breed on the yield and quality of cow’s milk. On the selected dairy farm, cows of two different breeds Montbeliarde and Polish Holstein-Friesian between 45th-100th days of lactation, were managed under the same environmental conditions. Milk samples were collected twice (in May and June 2008) from 97 (n = 51 and 46 for Montbeliarde and Polish Holstein-Friesian, respectively) cows. Montbeliarde cow’s milk was characterized by significantly lower milk yield and somatic cell count. Higher level of C18: 2 cis-9 trans-11 and almost 2-fold C20:5 n-3 (P ≤ 0.01) was also recorded. However, Polish Holstein-Friesian cow’s milk had a better composition of protein fraction (higher concentration of lactoferrin, α-lactoalbumin and β-lactoglobulin) and higher concentrations of vitamins D and E. Moreover, milk of Polish Holstein-Friesian breed was characterized by more favorable fat fraction with significantly lower concentrations of saturated fatty acids (C14:0, C18:0) as well as lower atherogenic and thrombogenic indexes and higher concentration of C18:2 trans-10 cis-12, C20:3 n-6 and C 22:6 n-3. This study was the first one comparing biological quality of Polish Holstein-Friesian and Montbeliarde milk under the same environmental conditions in Polish production systems.

The aim of this study was to determine the effect of substitution of 50% of soybean meal protein with 310–350 g/kg diet of raw chickpea seed protein on the chemical composition, fatty acid profile, dietary value, and antioxidant status of breast and thigh muscles, as well as the antioxidant status of blood serum, in Ross 308 male broilers. In the 42-day experiment, one-day-old male broiler chicks were assigned to two nutritional groups (n = 100 in each, 20 birds in each group, and 5 replications). In the control group, 100% of protein in the feed was derived from soybean meal. In the experimental group, 310–350 g/kg protein from raw chickpea seeds was introduced. Data with a normal distribution were analyzed using the Student t-test, and the relationships between the traits were assessed with the use of Pearson’s correlation coefficients. p < 0.05 was considered statistically significant. The replacement with chickpea protein did not exert an impact on the final body weight, feed consumption, and feed conversion ratio compared to the control group. However, it induced changes in the color of the breast muscles (increased L* and b* values), and reduced the cholesterol content. The addition of chickpea seeds improved the fatty acid profile, mainly in the breast muscle. A decrease in the total SFA content and a higher level of unsaturated fatty acids (UFA), UFAs/saturated fatty acids (SFAs), polyunsaturated fatty acids (PUFAs), omega-3, and omega-6 were observed in the experimental group. Additionally, the chickpea-supplemented group exhibited better values of meat quality indicators (atherogenic index-AI; thrombogenic index–TI, ratio of saturated fatty acids to unsaturated fatty acids-S/P, n-6/n-3, hypocholesterolemic/Hypercholesterolemic ratio-h/H). It can be concluded that raw chickpea seeds are a good source of protein in broiler chicken nutrition, and can replace the traditionally used protein source (soybean meal), simultaneously exerting a positive effect on the dietary value of poultry meat and an expected enhancing impact on consumer health.
