AbstractThe aim of the study was to perform feeding experiments on growing pigs in order to assess the impact of macroalga Enteromorpha sp. enriched with Zn(II) and Cu(II) ions via the biosorption process on the mineral composition of blood, meat, liver, feces and urine. In the control group, microelements were supplemented as inorganic salts, whereas in the experimental groups they were replaced by enriched macroalga. After 3 months of the feeding experiment, it was found that the meat was biofortified with Cr, Mn, Fe, Cu and Zn. The average content of Zn in the blood from the pigs fed with algae was higher by 9.5%, compared to that in the blood from pigs in the control group. The liver of growing pigs from the experimental group contained 16% less Cu and 18% less Zn than the liver in the control group. Growing pigs fed with macroalgae excreted in feces 27% more Zn than growing pigs in the control group, but 3.5 times less Cu. It could be concluded that the bioavailability of microelements to pigs from algae was higher than from the inorganic salts. Baltic macroalgae enriched with microelement ions could be potentially used as a biological feed additive.

In the present study, the effect of macroalga Enteromorpha sp. enriched with Zn(II) and Cu(II) ions on daily amounts of feces and urine excreted by growing pigs, apparent fecal nutrient digestibility and daily nitrogen balance and retention, meat quality and the slaughter value of carcasses was examined. The duration of feeding experiments was 87 days. In the control group, the requirement for zinc and copper was covered by inorganic salts, whereas in the experimental group algae enriched with these elements via biosorption were supplemented. No effect of Enteromorpha sp. on the increase in digestibility of dry matter, dry organic matter, crude protein, crude fat and nitrogen-free extractives was observed. Statistically significant differences concerned only the digestibility of crude ash. The daily amount of excreted feces and urine did not differ significantly between groups. Meat from pigs in the algal group was characterized by a lower water absorption and drip loss and contained less fat and more protein than meat from the control group. Furthermore, a slight darkening of the meat was observed. The weight of the liver was lower in pigs from the algal group. Enriched macroalga Enteromorpha sp. may be introduced into pig nutrition as a feed material as an alternative to inorganic salts.

The influence of feeding high-performance cows of the energy feed additive Cobiotic Energy on the physiological state and productivity have been studied. Experiments have been carried out on with groups of dairy cows with 10 animals each during 55 days. The diet of cows of the first control group consisted of haylage of cereal and leguminous plants, corn silage, molasses, cereal hay, and feed of own production. 0.3 kg of feed additive has been introduced into the diet of animals of the experimental group II 15 days before calving, in the first 10 days after calving, as compensation for energy losses, 0.75 kg 3 times a day. In the next 30 days of the milking season with the ration of animals of the experimental group II, 0.25 kg of Cobiotic Energy has been fed, sprinkling it on top of the feed mixture. It has been established that the use of feed additives in the diets of cows has a positive effect on feed intake, physiological condition and animal productivity. It was determined that concentration of metabolizable energy in 1 kg of dry matter of the diet made 9–16– 9.2 MJ. The diet contained 12.8–13.0 % of crude protein per 1 kg of dry matter, the concentration of fiber in dry matter made 22.3– 22.0 %. The sugar-protein ratio made 1.04:1; 1.0. In terms of energy nutrition, the diet of the experimental group due to the inclusion of the feed supplement was 6 MJ higher, however, it slightly affected concentration of metabolizable energy of the diet. The energy-protein ratio corresponded to 0.2– 0.21. The nitrogen balance in the rumen was positive in all the animals and was at the level of 0.13–0.4 g. Feeding animals with supplement in the diet in the last 15 days of the dry period, during the first 10 days after calving and the next 30 days of the milking period promoted activation of protein biosynthesis and energy metabolism, as evidenced by an increase in serum total protein and its albumin fraction and ultimately increased animal productivity. The studied supplement use in the diets for cows makes it possible to increase performance of cows by 8.0 %, fat content by 0.1 %, protein by 0.24 %, lactose by 0.11 %, reduce the cost of feed for obtaining natural milk by 6.1%. Key words: feed supplement Cobiotic Energy, cows, diets, blood, milk yield, feed costs, milk quality.

The Effect of Feed Additive Containing Vitamins and Trace Elements on the Elements Profile and Growth of Skin Derivatives in HorsesAn important role of nutritional supplements in the quality and growth of skin derivatives is not sufficiently explored. The aim of our experiment was to recognize how the application of selected vitamins and an organic source of zinc and copper affects the growth and elemental content of hooves and hairs. Sixteen warm-blooded horses were divided into two groups. Both groups received the same basic feeding ration, which was enriched with a feed additive for the experimental group. The contents of individual elements in hoof and hair samples were established using the atomic absorption spectrometry method. Samples from the experimental group of horses showed a significantly increased amount of zinc (P<0.01), copper and manganese (P<0.05) deposited in the hoof and a significantly decreased (P<0.05) amount of manganese, iron, and calcium deposited in the hair after nine months of monitoring. Differences between initial and final samples of hooves and hair were insignificant in the control group. The growth rate of hair and hoof wall was significantly higher (P<0.01) in horses from the experimental group than from the control one. Horses receiving the feed additive achieved a faster growth of the hoof horn with an adequate quality of hooves in our experiment. The experiment shows that the hair is not a reliable indicator of nutritional status of horses. However, assessing the impact of individual vitamins and trace elements, or the impact of various sources of trace elements on the elements profile and growth rate of skin derivatives of horses should be subject to further observation.

The article presents the results of research on the effect of feed additive “Metisevit” and liposomal drug “Lipointersil” on the level of vitamins in the blood of bulls in experimental chronic cadmium toxicosis. The research was conducted on the basis of a farm in the village of Ivanivtsi, Zhydachiv district, Lviv region, on 15 bulls of six months of age, Ukrainian black-spotted dairy breed, which were formed into 3 groups of 5 animals each: control and two experimental groups. The bulls of the control group were fed cadmium chloride at a dose of 0.04 mg/kg body weight for 30 days. The bulls of the first experimental group were fed cadmium chloride at a dose of 0.04 mg/kg body weight for 30 days and fed a dietary supplement “Metisevit” at a dose of 0.36 g/kg of feed. The bulls of the second experimental group were fed cadmium chloride at a dose of 0.04 mg/kg body weight for 30 days and fed a dietary supplement “Metisevit” in the above dose. On the first and seventh days of the experiment, bulls of this experimental group were injected intramuscularly with liposomal drug “Lipointersil” at a dose of 5 ml per animal. The composition of the liposomal drug “Lipointersil” includes interferon and milk thistle. In the study of the non-enzymatic part of the antioxidant system of the body of bulls under cadmium load found a decrease in vitamins A and E. The use of feed additive “Metisevit” increased the content of vitamin E in the blood of bulls of the second experimental group by 10.5 % experiment – by 37.9 % relative to the control group. With the additional use of liposomal drug “Lipointersil” in the blood of bulls found a more likely increase in vitamin E levels throughout the experiment than in the second experimental group, where respectively on the 15th and 20th day of the experiment, this figure increased by 35.3 and 55.1 %. The increase in the content of vitamin E in the blood of experimental animals is due to the feeding of the feed supplement “Metisevit”, which contains this vitamin. A similar increase is observed in the study of vitamin A in the blood of bulls of experimental groups. It was found that when using a feed additive and liposomal preparation for bulls, on the 15th day of the experiment the level of vitamin A in the blood of the first experimental group increased by 19.4 %, and in the blood of the second experimental group – by 26.9 % relative to the control group. Thus, the use of feed supplement “Metisevit” and liposomal drug “Lipointersil” for bulls, which are under conditions of cadmium load, helped to increase the non-enzymatic system of antioxidant protection, namely vitamins A and E.

Introduction:Psychological impact of Therapeutic Patient Education (TPE) for dialysis patients is rarely evaluated since the focus of many studies is on medical variables (i.e., adherence).Objectives:The aims of this study were: 1) to estimate the impact of a TPE program on knowledge, depression and anxiety, 2) to examine change in knowledge as a mediator of the effects of a TPE program on mental health.Method:This study was conducted in three hemodialysis units and comprised two groups: an experimental group with education and a control group with routine care. The program was based of 5 educative sessions. Knowledge, depressive and anxious symptoms were assessed with self-reported outcomes measured before and 3 months after the program.Results:The sample comprised 125 patients. Knowledge about vascular access and nutrition (p < 0.01) and depressive symptoms increased in the experimental group (p < 0.01). Analysis of mediation showed that changes in knowledge about vascular access were a significant mediator of the effects of the program on depressive symptoms (F = 4.90;p = 0.01).Discussion:Knowledge acquired during an educational program could lead to an emotional change. Improving knowledge often leads to an awareness of the risks that can modify the psychological state of patients by reminding them of their vulnerability. This study shows that it is required to be attentive to the way of transmitting knowledge. It’s necessary adapting this transmission to the needs of patients and promoting the acquisition of psychosocial competence too.Conclusion:This study shows that knowledge acquired during an educational program can lead to an emotional change in the short term. A long-term follow-up of the population should be interesting to observe these emotional effects.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Writing is an intricate process that encompasses various factors and is a key skill for English as a Foreign Language (EFL) students. Thus, writing assignments are vital for any curriculum. One of the essential aspects of effective writing includes good grammar knowledge. Advocates of process writing argue that a free-writing journal is a practical approach to teaching EFL students writing. This study is intended to examine the impact of the free-writing journal on EFL learners. This study was conducted on 80 students from a writing course at the University. Thirty-five students were randomly selected to join the free-writing program—the experimental group—and 45 students were kept in their regular structured writing program—the control group. The experimental group selected topics of interest to them and was encouraged to write in English freely without concern for errors, whereas the control group followed a regular structured writing program where the topics were selected for them and they wrote following a clear guideline. Five major areas were investigated to evaluate students’ progress: the number of words written, spelling, capitalization, subject-verb agreement, and punctuation. The researcher conducted semi-structured interviews with 10 students of the experimental group to elicit their perception of the free-writing program. According to the analysis, students in the free-writing program acquired better grammar acquisition than the control group. The researcher also observed students’ perception of free-writing at the end of the study and found that free-writing improved their writing skills.
