“…The data in Table 1 demonstrate that in the animals of the control group the phagocytic activity of neutrophils in blood did not change throughout the experiment, indicating the development of this mechanism of natural protection on earlier stages of post-natal ontogenesis. This can be due to early inhabitation of the peripheral immunocompetent organs and tissues by cells with protective abilities and compensatory property of the immune system of rabbits to respond to the decrease in humoral factors of protection (Darmohray et al, 2019). At the same time, phagocytic index which characterizes the number of the microorganisms occupied by one active phagocyte and phagocytic number in rabbits of the control group with age had a tendency towards insignificant increase, compared with the preparation period.…”

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 literature sources report that providing the animals with optimum amount of microelement reduces stress that occurs in rabbits as a result of weaning from their mother and was studied perfectly in poultry farming (AbdEl-Hack et al, 2019;Darmohray et al, 2019). Selenium is included in the supplement and is a microelement necessary for animals.…”

Using nanotechnologies to obtain compounds of mineral substances is promising because of the importance of the amount of mineral substances, but the limiting factor is particularly their bioavailability in the digestive tract. The conducted studies determined the stimulating effect of nanoaquachelates of separate biogene microelements on the course of biochemical processes of the organisms of animals, their productivity and quality of the obtained products. However, the mechanisms of impact of carboxylates of separate elements and their combinations on functioning of physiological systems of various species of animals, level of transformation of these elements into the products and their biological value remain unstudied. Therefore, the objectives of the study were changes in hematological biochemical and productive parameters of the organisms of rabbits consuming I, Se, S, the impacts of these elements on their organism from the 53 to 85th days of life. Studies were performed on young Termonde rabbits. Animals of experimental groups I, II, III, and IV were fed with feeds of the diet of the control group for 24 h with water containing solution of І, Se, S calculated respectively as 2.5, 5.0, 10.0 and 20.0 µg of І/L of water. The experiment lasted 45 days, including a 12 day preparation period and 33 day experimental. On the 53rd day of life of animals in the preparation period, and 68th and 85th days of life in the experimental periods (15th and 33rd days of watering with supplements), we collected samples of blood from the marginal ear vein of 6 animals (3 males and 3 females) of the group for hematological and biochemical studies. We determined that watering with the solution of microelements І, Se, S led to changes in the overall amount of white blood cells, making it 17.1% lower in the blood of animals of the experimental group II, 26.2% higher in group ІІІ on the 15th day, and 12.0% higher in group IV on the 31st day of the experiment compared with the control. Absolute amounts of lymphocytes, monocytes and granulocytes by the periods of the study were observed to have no significant changes throughout the study, though their parameters were within the physiological values compared with the control. The amount of red blood cells in the blood of rabbits of experimental groups І, ІІ and ІІІ was higher respectively by 8.1%, 5.7% and 12.0% at the first stage of the study and 18.1%, 13.3%, 24.5% and 24.9% higher in animals of experimental groups І, ІІ; ІІІ and ІV at the final stage of the study compared with the control group. Hemoglobin concentration in blood of rabbits of experimental groups II and III during the study was significantly higher. Hematocrit value in blood of rabbits of experimental groups I–III was significantly higher on the 33rd day of the experiment compared with the control. Consumption of solution of microelements in the amount of 10.0 µg of I/L by the animals of experimental group III led to 15.1% higher content of total protein in the blood on the 33rd day of the study compared with the control group of animals. The level of creatinine was no higher than the physiological parameters and was 9.2%, 15.0% and 15.4% higher in the blood of rabbits of experimental groups II, III, IV on the 33rd day of the experiment compared with the control group. No significant changes in the content of triacylglycerols in the blood of rabbits of the experimental groups were seen throughout the study. However, the content of cholesterol in the blood of rabbits of experimental groups III and IV was significantly higher at the first stage compared with the control group. Further, it is practical to study physiologically substantiated amounts of solution of microelements І, Se, S in the diet of mother rabbits to determine their effect on their ability to become pregnant, reproductive function, milk production and survival of offspring.

“…It is necessary when preparing rations to take into account not only the amount of nutrients in the feed, but also their digestibility, i.e. how much of feed is absorbed by rabbits (Dadakova et al, 2011;Dadakova et al, 2012;Zhu, et al, 2014;Darmohray et al, 2019). To maintain vital functions and the formation of products, the rabbit's body needs a constant supply of energy.…”

The purpose of the study is to study the influence of different vitamin-mineral supplement “Tekro” doses on biochemical parameters in blood plasma and liver of rabbits of New Zealand breed. The research methodology is based on research according to generally accepted research methods. Biochemical parameters were studied in rabbits’ organisms at 45, 60, 75 and 90 days of rearing with feeding of different doses of vitamin-mineral supplement “Tekro”, namely 3 %, 3.5 %, 4 %. The academic novelty is that nowadays the problem of the effect of different vitamin-mineral supplement “Tekro” doses on biochemical parameters in the blood and liver of rabbits has not been studied. Analyzing the indicators of the total protein content in the blood plasma of rabbits of the experimental groups and the control one for 90 days, it was noted that there was no significant difference in the indicators. In the liver of rabbits of the age from 45 to 90 days there was a tendency to increase the protein content due to the effects on the body of various doses of vitamin and mineral supplement “Tekro”. It has been established the positive effect of vitamin-mineral supplement “Tekro” on ALT activity of rabbits in experimental groups. At the age of 75 days, significantly higher ALT activity was recorded in rabbits of the 3rd experimental group by 35.8 % compared to animals in the control group.
