The purpose of these studies was to determine status of metabolic processes in clinically healthy horses of sport breeds in spring period. Blood samples for biochemical studies were collected from 12 clinically healthy 7–9 month-old stallions of Ukrainian horse breed at Dnipropetrovsk region equestrian club. Protein (albumin, globulin, urea and creatinine) and mineral (common calcium and inorganic phosphorus) metabolic statuses, level of glucose, vitamins A and E and acid, as well as activity of hepatospecific enzymes (ALT, AST and AP) were determined using common techniques. It has been found that common protein level was within the limits of physiologic norm, although the level of albumins was decreased at the average rate of 12.0%, and the level of β- and γ-globulins was increased at the average rates of 5.2 and 11.3% respectively. AST activity was decreased at the rate of 38.0% regarding to physiological norm. Thereby, urea and creatinine concentrations were within the referent levels. Hyperglycaemia was observed in 50.0% of tested animals with maximal excess at the rate of 44.0%. Also, decreasing of common calcium and inorganic phosphorus levels was determined at the rate of 16.0 and 58.6%, vitamins А and Е — at the rate of 64.0 and 48,6% respectively, in comparison to lower level of physiological norm. The average index of acid capacity reached maximal referent levels. At the same time, it was increased in 33.3% of animals. Therefore, detected changes in biochemical indices in horse blood evidence that various metabolic disorders progress in clinically healthy stallions at spring and may furtherly lead to the appearance of metabolic syndrome

During the concluding phase of a six-year grazing trial a study was made of the steers and the pasture material from paddocks annually fertilized with 125 kg ha-1and 250 kg ha-1of superphosphate. Plucked pasture samples from the low and high superphosphate treatments contained 0.11 and 0.15 per cent phosphorus, 0.83 and 0.91 per cent nitrogen and 0.12 and 0.12 per cent sulphur, respectively. The N: S ratio of these samples were 6.8 and 7.6 and the in vitro digestibilities were 41.6 and 44.9 per cent. There were marked seasonal patterns in the concentrations of all components with minimum values in the winter months when liveweight gain was lowest. Greater superphosphate application increased mean liveweight gain (0.29 to 0.41 kg head-1day-1), mean plasma concentrations of both urea-nitrogen (6.3 vs 5.0 mg 100 ml-1) and of inorganic phosphorus (6.7 vs 6.3 mg 100 ml-1). The mean blood sulphate-sulphur concentration of 28 �g ml-I was not influenced by treatment. Comparisons of the levels of nutrients in pasture and blood with published requirements indicated that neither sulphur nor phosphorus were deficient in either treatment. However, the between treatment differences in both nitrogen and phosphorus levels could not be ignored as possible reasons for the difference in animal production between the two levels of superphosphate application. Improved animal performance associated with increased application of superphosphate was probably influenced more by the induced changes in the organic components rather than the mineral levels of the pasture material.

У роботі представлені результати наукових досліджень щодо розробки та впровадження у ветеринарну практику екологічно чистих препаратів, а саме плацентарних, здатних нормалізувати метаболічні процеси у тканинах, та відновлювати структуру та функції органів і систем організму. Встановлено, що двократне введення хоріоцену збільшує вміст білка в крові на 1,5 % у порівнянні з показником першої доби після опоросу та на 5,3 % – показника тварин контрольної групи на 28-му добу. Вміст глюкози після введення препарату збільшився у всіх групах р<0,001, але у дослідних групах цей показник був вищим, ніж у контрольній на 8,7, 7,0 та 6,1 %. На фоні гіперфосфатемії вміст неорганічного фосфору в крові свиноматок 3-ї дослідної групи на 28-му добу був на 17 % нижчим, ніж у свиноматок групи контролю. The paper presents the results of research on the development and implementation of environmentally friendly practices of veterinary preparations, namely placental able to normalize metabolic processes in tissues and restore the structure and function of organs and body systems. We established that the yard at multiple input of «Horiotsen» increased protein levels on 1,5 % compared to the index of the first days after farrowing and 5,3 % – rate of animals in the control group at 28th day. Glucose increase after the injection in all groups – p<0,001, but in the experimental groups the figure was higher than in the control one by 8,7, 7,0 and 6,1 %. Against the background of hyperphosphatemia content of inorganic phosphorus in the blood sows of 3rd research group at the 28th day was 17 Im% lower than in the control group of sows.

Intervertebral discs are rather complex structural units of the spine. It is believed that a disturbance of the factors of their homeostasis immediately leads to changes in the bone tissue of the vertebral bodies and, consequently, to pathological changes at the level of the vertebral-motor segment. It follows that the maintenance of normal metabolism within the discs is one of the key directions in the prevention of many clinically important lesions involving the entire vertebral complex. The causes of metabolic processes disorders in the intervertebral disc can be divided into several levels: chronic diseases that directly affect the blood supply to the spinal column as a whole; diseases that affect the permeability of the capillary zone of the subchondral zone of the vertebral bodies; disturbances in the delivery of nutrients into the disc through its matrix, which serves an important selective barrier. However, regardless of the level of the causes of metabolic disorders, all of which eventually lead to anatomical and functional changes in the intervertebral discs and to their subsequent incapacity to provide the daily life cycle of the vertebral complex, consisting of periods of stress and relaxation. Thus, based on the known literature data we can conclude that: the intervertebral discs to date, remain poorly understood elements, however even from a narrow range of studies on this subject it is evident that their functionality is largely dependent on the properties of the disc matrix and the interstitial nature of metabolic processes.
