Zinc is necessary for maintaining the immune status, and its deficiency in the organisms of animals is usually accompanied by the condition of immune deficiency. The objective of the study was determining the effect of different amounts of zinc on the immune-biological reactivity and productivity of the organism of rabbits after their weaning on the 50th and 86th days of life. For the study, rabbits with the weight of 1.2–1.4 kg were selected and divided into four groups (control and three experimental). The rabbits of the control group were fed with unlimited balanced granulated compound feed, and had free access to water. The animals of the I, II and III experimental groups were watered with zinc nanoaquacitrate in the amounts of 0.25, 0.50 and 0.75 mg of Zn/kg of body weight. Compared with the control group, watering of the animals of the experimental groups with zinc nanoaquacitrate to a greater extent affected the content of phagocytic activity, lysozymic and bactericidal activities of the blood serum as integral factors of non-specific cellular and humoral resistance of the organism, which manifested in the increase in their content in blood on the 12th, 24th and 36th days of the experiment. Use of organic supplement in the diet of rabbits had a stimula­ting effect on the functioning of the immune system of their organism, which was seen in the higher content of total immunoglobulins, sialic acids and ceruloplasmin in the blood of animals watered with zinc nanoaquacitrate in the quantities of 0.50 and 0.75 mg of Zn/kg of body weight on the 24th and 36th days of the experiment. Use of organic compound of zinc in the diet caused high parameters of growth of the organism of rabbits during the period of 36 days, which manifested in the highest parameters of average-day increments and body weight on the 86th day of the life of the rabbits from the III experimental group, which received zinc nanoaquacitrate in the amounts of 0.75 mg of Zn/kg of body weight compared with the control group. Watering rabbits with zinc nanoaquacitrate during the study was accompanied by probable changes in the number of erythrocytes, concentration of hemoglobin and erythrocyte indices, which could indicate a positive effect of the employed additives on the hematopoietic function of the rabbits’ organism. The data of the performed experiment suggest that watering with larger amounts of organic compound of zinc has a positive effect on the processes of formation of immuno-physiological reactivity of the rabbits’ organism and increase in their productivity. The practical purpose is the study of the impact of watering with zinc nanoaquacitrate on the immuno-biological reactivity of the organism of rabbit dams during the period of lactation.

The work aims to study the effect of different doses of the experimental probiotic preparation “Plantarum” when fed to pregnant animals on their reproductive qualities, as well as on the growth and development of young animals. To obtain young animals, four groups of goats were formed in the type of the Saanen breed, 20 heads each. In the first (control) group, the animals received a standard diet, in the diet of the animals of the second, third and fourth groups in the second half of pregnancy, the probiotic preparation “Plantarum” was additionally introduced, containing Lactobacillus Plantarum, Propiobacterium freudenreihii, in dosages from 0.4 to 0.8 ml/kg of body weight per day. From the offspring of the goats of the experimental groups, four groups of 12 goats were formed. The highest percentage of preservation (94%) and the highest business output of kids per 100 queens (150%) were observed in the fourth experimental group (0.8 ml). The goats of the second, third and fourth groups exceeded the body weight of their contemporaries from the control group by 3%, 6.3%, and 8.8%. The highest indices of the absolute increase in body weight by age periods were noted in the fourth group of goats. There were no significant differences in body build indices during the experiment between the goats of the control and experimental groups. Thus, the maximum positive effect was observed with the introduction of a probiotic preparation into the diet of pregnant goats at a dose of 0.8 ml/kg of body weight per day.

The present study aimed at investigating the impact of textual enhancement on the comprehension of transparent and opaque English idioms among Spanish lower-intermediate students studying English as a foreign language. Two short texts including visually enhanced idioms (i.e., they were underlined) were designed for the Experimental Group, and the Control Group received an unenhanced version of the texts. The results reveal that textual enhancement made transparent idioms salient enough for them to have an impact on comprehension; however, underlining had a poorer effect on comprehension as far as opaque idioms are concerned. In addition, we aimed at examining the effect of textual enhancement on the noticing of idioms. Findings show that it did not have a positive effect on recognition of idioms, since the Control Group outperformed the Experimental Group in the multiple-choice task.

The article considers the impact of changing training aids during weight training in the gym, without changing the amount of load and intensity. The study involved twenty-eight visitors to the gyms of the city of Kharkov, from 18 to 32 years and experience of one year. The study was conducted in two stages, the duration of each was 2 months. The control group was engaged without changing the exercises, and the experimental group with changing the exercises in the second stage. The volume and intensity of the load did not differ between the groups. Results. Anthropometric indicators were studied at the beginning and end of the second stage of the study. The equipment used Tanita RD 545 scales, an application for the My tanita mobile device, and an elastic band for measuring circles. The experimental group improved their results in the following indicators: body weight, fat percentage, muscle mass, shoulder circumference, chest and thigh circumference. At the end of the study, the experimental group surpassed the control group as a result of the following indicators: body weight, fat percentage, and muscle mass. The results of the circles of the muscle groups at the end of the study did not differ between the groups. Conclusions. Changing such factors of training influence as exercises has a positive effect on the result of fitness training in the gym. Despite the invariability of the amount of load and its intensity, the change in exercises led the participants of the experimental group to a significant improvement in performance, both in comparison with the beginning of the study and in comparison with the control group.

AbstractThe aim of the study was to determine the effect of these substitutions on body weight and slaughtering performance, post-mortem changes, sensory characteristics and chemical composition of selected muscle groups of male and female pheasants. The tests were carried out on pheasants during 5–16 weeks of rearing in enclosed aviaries. Four groups of 8 females and 8 males were formed, and the experimental factor was the supplementation of calcium, iron, zinc and copper salts with glycinates of these elements. The control group received a feed blend containing 100% of the mineral need as salts. In the E-25 group, 25% of the salts were replaced by glycinates, in the E-50 group 50% of the salts were replaced, and in the E-75 group only glycinates comprising 75% of the total mineral content were used and no salts were included, with vitamin D3 replaced by calcitriol. For the duration of the study, feeding was at will and the birds had free access to water. In addition, pheasants were weighed at the age of 4, 8, 12 and 16 weeks. Daily feed intake was monitored. At the end of the experiment, when all the pheasants were 16 weeks old, they were weighed and decapitated. The breast, thighs and drumsticks and the heart, liver and gizzard were removed from the chilled carcasses. Supplementation of calcium, iron, zinc and copper salts with 50% glycinates in feed mixtures for pheasants over a period of 5–16 weeks resulted in a slight improvement in the slaughter weight of birds and a significant increase in crude ash, calcium and zinc, while at 75% supplementation and when calcitriol was used instead of vitamin D3, increased phosphorus levels were found in the pheasant muscles analyzed. Males had higher body weight, body weight gain, carcass, liver and gizzard weights, and their muscles had more magnesium and potassium and less calcium, sodium and iron than females.

The purpose of the study was to investigate the effect of putting up for 58 days life of various amounts of nanosilicon citrate infusion obtained by the method using nanotechnology and metasilicate sodium, on the growth and development of the body of the rabbits of the Hyla 110 of the diurnal age. The rabbits of the control group fed without restriction a balanced granulated feed with free access to water. Animals of the experimental groups I, II and III fed feed of the control group's diet and, during the day, dispensed the citrus application, accounting for 25; 50 and 75 μg Si/kg body weight. The females of the IV and V experimental groups feed the diet of the control group and set the sodium metasilicate (Na2SiO3H2O) with water in an amount of 2.5 and 5.0 mg Si/kg body weight, respectively. The trial lasted 68 days, including a preparatory period of 10 days, an experimental one of 58 days. On the 110-th day of life, animals of all groups were killed to determine the mass indices of carcasses, internal organs and skin. Exposure of nanosilicon citrate to animals in the I, II, and III experimental groups during 58 days was characterized by an increase in body weight of 4.0; 9.5 and 8.9%, while the use of sodium metasilicate in IV and V groups increased by 3.1 and 4.2% compared with the control group. The carcass weight correlation was correlated with body weight and in animals of groups ІІ and ІІІ, respectively, was higher by 10.6 and 9.0%, while in other experimental groups it was greater in the range from 2.4 to 2.9% compared with control. Research on the development of the body of rabbits indicated a tendency to a higher level of body mass index and internal organs in animal experimental groups than in the control, although the more pronounced differences were in rabbits I–III groups, which were deposited on nanosilicon citrus application. Ribbons infusion of citrate in comparison with metasilicate of sodium and control group, to a greater extent influenced the mass of the skin and the mass of the liver, which was reflected in an increase (P < 0.05) of their mass on 110 days of life. The use of an organic compound of silicon in the amount of 50 and 75 μg Si/kg of body weight, during 58 days, contributed to the activation of metabolic processes in the skin. Perhaps higher (P < 0.05) indices of the thickness of the dermis and subcutaneous fat and the total thickness of the skin of rabbits compared with the control group were established. The conducted studies showed more pronounced positive effects on the growth and development of the body of rabbits of the organic compound of silicon in the amount of 50 and 75 μg Si/kg body weight in comparison with its inorganic compound and control group.

The article presents results on the influence of different amounts of sulfur citrate, manufactured using nanotechnology and sodium sulfate in rabbit diet from 60 to 118 days of age on the hematological parameters of their organism. Studies have been conducted on 30 rabbits of the Hyla hybrid divided into six groups (control and five experimental), 6 animals in each. Animals were kept in regulated microclimate and illumination in mesh cages of 50×120×30 cm. Controlled rabbits fed without restriction a balanced granulated feed with free access to water. The young of the first (E-II), the second (E-II), the third (E-III) and the fourth (E-IV) experimental groups feed the diet of the control group and, during the day, dispensed sulfur citrate from the calculation of 2; 4; 8 and 12 mg S/kg body weight. Rabbits (E-V) of the experimental group fed the diet of the control group and set water with sodium sulfate (Na2SO4) in the amount of 40 mg S/kg body weight. In the preparatory period – 60 days and in the experimental period – at 91 and 118 days of life (31 and 58 days of delivery of supplements), blood samples were collected from the regional anterior vein of rabbits for hematological studies performed using an automatic hematologic analyzer (Orphee Mythic-18, Switzerland). Researches have shown that the administration of citrate sulfur in the amount of 8 mg S/kg of body weight was marked by a greater number of red blood cells and leukocytes, respectively, by 13.4 and 23.3% (P < 0.05) and with a higher level of HCT at 16.2% (P < 0.05), MCH, RDV and MCHC, respectively, 11.1; 14.5 and 2.6% (P < 0.05) on day 58 of the experiment compared with the control group. In the blood of animals in the 2nd experimental group, a higher concentration of hemoglobin (Р < 0.05) was observed at 31 days and a higher HCT (Р < 0.05) level was 58 days compared to control. Thus, the results of the study of the hematological parameters of the body of rabbits indicate their positive changes in the actions of the physiologically substantiated amount of organic sulfur, which contributed to the activation of metabolic processes.
