In the conditions of the Republic of Belarus there were studied circadian rhythms of some haemotological and biochemical blood indexes of clinically healthy calves and calves with a respiratory syndrome. There was analyzed the efficiency of administration a new complex mineral preparation CMP for correction of internal desynchronoses in complex therapy of calves with respiratory pathologies. Diseases of calves with a respiratory syndrome were accompanied by infringements of circadian fluctuations rhythm (internal desynchronosis) of haemotological and biochemical blood indexes. Application of an antimicrobial preparation Ampicillin for treatment of respiratory diseases of calves promoted the recovery of calves. Introduction of CМP preparation into therapeutic regimen of calves with respiratory syndrome proved to be rather effective; it promoted the correction of metabolic desynchronoses which accompanied the basic disease. Combined application of CМP and Ampicillin made it possible to speed up the clinical recovery of calves and on 30% to prevent animal mortality.

Influence of inorganic and organic salts of lithium on activity of amplifiers and concentration of metabolites in plasma of chicken blood in the process of vaccination against infectious bursal disease was studied in the conditions of the Republic of Belarus. After administration of lithium of citrate, sulfate and succinate there were noted the metabolic disorders. Research results testified that a dry live-viral vaccine on the basis of a strain KMIEhV-61 did not render essential influence on biochemical indicators of blood plasma. At the same time, immunization of chickens against application of salts of lithium (carbonate, sulphate, citrate, succinate) caused to authentic decrease in activity of alanine aminotransferase that testified to function oppression of hepatocytes. Application of lithium of citrate, sulfate and succinate made it possible to considerably increase the concentration of uric acid that was connected, apparently, with infringement of secretory function of kidneys. Metabolic disorders were observed in various terms of research - at 3, 7 and 14 days after vaccine administration. | Изучено влияние неорганических и органических солей лития на активность индикаторных ферментов и концентрацию метаболитов в плазме крови цыплят при вакцинации против инфекционной бурсальной болезни (ИББ). Выявлены метаболические нарушения при использовании лития цитрата, сульфата и сукцината. Полученные результаты исследований свидетельствуют о том, что сухая живая вирус-вакцина из штамма КМИЭВ-61 не оказывает существенного влияния на биохимические показатели плазмы крови. В то же время иммунизация цыплят на фоне применения солей лития (карбонат, сульфат, цитрат, сукцинат) приводит к достоверному снижению активности АлТ, что свидетельствует об угнетении функции гепатоцитов. Применение лития цитрата, сульфата и сукцината способствует также достоверному повышению концентрации мочевой кислоты, что связано, по-видимому, с нарушением выделительной функции почек. Метаболические нарушения наблюдаются в различные сроки исследований - на 3, 7 и 14 дни после введения вакцины.

In the conditions of the Republic of Belarus there was studied the activity of hepatic specific enzymes of blood serum of bull calves of black-and-white breed in course of application of various doses of zinc-containing preparations. Application of zinc-containing preparations led to multidirectional change of activity of hepatic specific serum enzymes. Application of Zinkovet preparation in dose of 1,8 g/100 kg of live weight made it possible to essentially grade the indexes of hepatic tissue affect. In the experimental group at animals there was marked the lowering in activity alanine-aminotransferase, serum glutamic oxalacetic transaminase and gamma-glutamyl transpeptidase. At the same time, there was noted the increasing of zinc-containing enzymes activity (sorbitol dehydrogenase and glutamate dehydrogenase). All these processes were caused by zinc inclusion into the metabolic process.

The influence of various light regimes on productive indices of broiler chickens cultivation of СОВВ cross taking into consideration the course of some exchange processes was studied in the conditions of the Republic of Belarus. There were formed 4 groups of one-day-old chickens with the approximately identical body weight. For the chickens of a control group there was used the standard for Belarusian poultry farms light regime, i.e. 23 hours of light and 1 hour of darkness (23L:1D), in three experimental groups there were used the following light regimes: first - (3L:1D) х 6, second - (2L:1D) х 8, third - (1L:1D) х 12. The predetermined conditions were set by means of filament lamps with 15 W capacity. Throughout the whole experiment there was realized the identical feeding level for all groups: during the first growing period (1-30 days) chickens were fed with mixed fodder PK 5B containing 22% of crude protein and 296,6 kcal of exchange energy, during second period (31-42 days) - PC 6B containing 20% of crude protein and 332,2 kcal. In the applied mixed fodders there was used enzyme Rovabio. Research results showed that metabolic processes occurring in chicken body in the majority opf cases depended on application of various light regimes. Interchange of light and darkness periods (3 hours of light and 1 hour of darkness) х 6 at light exposure in 15 lk rendered the positive effect on the activity of endocrine systems of chickens of СОВВ crosses. In mentioned above group of chickens the hormones directed their metabolic processes towards increasing the productive indices, namely: daily average gain of chickens of the first group was authentically higher than the same index in the second and the third groups on 13,6% and 17,9%, respectively

In the conditions of biogeochemical zone of the Republic of Belarus the most important role in mineral metabolism is played by such major mineral elements as calcium, magnesium, phosphorus, potassium and trace elements - cobalt, cupper, iron, iodine, zinc, manganese, and selenium. Based on the above there was determined the interrelation between the content of these minerals in fodder and blood of milking and dry pregnant cows. As a result of realized study it was found out that the content of major mineral elements and trace elements in fodder did not always correspond to their level in blood. In the conditions of insufficient supply of Ca, F, Mg, K, Fe, Си and Co in cow diets, the level of potassium in blood was lower standard and the other analysed minerals were within the standard limits. There was stated the direct correlation relationship between the level of some biochemical indices and content of mineral substances in cow diets. Positive correlation was stated between the content of calcium and magnesium and cholesterin level in blood

In animal feeding technology much attention is given to application of biologically active substances for metabolism stimulation. One of such biologically active substances is carnitine, an anabolic preparation of nonhormonal nature, cofactor in system of oxidation of fat acids. It participates in processes of acetylation at oxidation of fat acids together with acyl-CoA and other enzymes, promotes carrying over of cytoplasmatic Coa-derivatives of fat acids inside mitochondrions. It increases absorption speed from a digestive path of nutrients of forage, raises use of fat acids for the power purposes. Under its influence synthesis of triglycerides decreases and synthesis of phospho-lipids increases. Carnitine also protects cells against toxic accumulation of components of acyl-CoA of endogenic or exogenous origins, such as acylic groups of carnitine ethers which then can pass into liver for dissimilation or in kidneys for allocation in urine. Carnitine synthesis satisfies body requirements, but in the conditions of a hightened stress, high productivity, as well as in the conditions of lowered carnitine content in forage or in the conditions of the increased content of fats it should be applied as additive to diet. As a result of the realized study it was established, that the optimal quantity of carnitine application in diets for stores husbandry and fattening is dose of 50 g/t of mixed fodders. Application of carnitine in an optimum dose renders the positive impact on animal organism, promotes the increasing average daily weight gain on 5,1% (Р less than 0,001). Application of carnitine in diets of swine stores increases a slaughter yield on 2,1%, meat content per carcass - on 2,3%, a loin eye area - on 8,8%. Carnitine application in a dose 50 g/t of mixed fodders makes it possible to receive the additional profit at a rate of 4,57 USD per 1 head
