<p>We studied the influence of a different level of a calcium and phosphorus in mixed fodders on morphological and biochemical indexes of a blood of Japanese quail. We selected 240 quails, which were divided into 6 equal groups - control and 5 experimental. Experimental quails were contained in six-fodders cell battery, each cell was 60x40x20 cm and contained of 20 birds (15 females and 5 males). At the beginning of the experiment the experimental quails had similar body weight indicators that were the same in the end of our research. When we fed quails with different levels of calcium and phosphorus wew registered that calcium, magnesium, total protein and alkaline phosphatase activity in their blood was within physiological norm. We identified no significant differences in these indicators. It should be noted that the highest content of phosphorus in the quail blood was observed in female birds of 6th experimental group, which exceeded by 23.1% the values in quails of control group with calcium content of 4.0% and phosphorus of 1.4% (P &lt;0.05). The introduction of different level of a calcium and phosphorus were not significantly affect the blood erythrocytes, leukocytes, and hemoglobin. The ratio of segmented rods, eosinophils, lymphocytes and monocytes in the blood of experimental birds was within the physiological norm of fluctutations. In content, there was a slight deviation (within 1%) was not statistically significant in the blood of the bird experimental and control groups, eosinophils and monocytes. The lymphocyte content was below 8.3% in the blood of all experimental bird groups. It is revealed that a level of a calcium of 4.0 % and phosphorus of 0.8, 1,1, and 1,4 % in rations of quails, promotes rising of a calcium level in skeleton of female quails and does not influence significantly the morphological and biochemical blood indices.</p>

The article consist data about effect of different levels of vitamin E and selenium in the diet of carps during their growing and also informationabout the influence on processes of lipid peroxidation and activity of antioxidant protection in their body.The experiment conducted in three experimental ponds. After wintering there were placed four ears mature females and males carp, six individuals in each group. Supplements of vitamin E administered at a rate of 25 mg/kg and drug «Sel–Plex» the rate of selenium – 0.3 mg/kg were added to further basic diet(BD) of female and male carp first experimental group (EG1). The second experimental group (EG2) received (BD) and vitamin E supplements in an amount of 75 mg / kg, and just as in EG1 – selenium – 0.3 mg/kg of feed.The control group received fish feed without additives vitamins and minerals.Feeding lasted for 30 days, due to the physiological needs of the fish feed. After spawning in fish of research and control group swere taken blood samples for biochemical research.The study led to a dose–dependent decrease (p < 0.01 – 0.001) content of TBA–active products and hydroperoxidase of lipids, but did not significantly effect onsuperoxide dismutase and glutathione peroxidase activity of blood So, the reduction of lipid peroxidation products in the carp’s blood of experimental groups probably was caused by the growth of non–enzymatic level, which is associated with fat–soluble vitamins.

As a result of research and production experience in the economy of the Nizhny Novgorod region, the effect of three-time administration of the drug «Selenopiran» at a dose of 300 mg during the dry season on the ease of calving, milk productivity and reproductive functions of cows was studied. For this purpose, two groups of cows (n=10) were selected: an experimental group and a control group. Starting from the confirmation of 6-month pregnancy, 25% oil solution of the drug «Selenopiran» at a dose of 30 ml was administered three times at intervals of 5–6 days to animals of the experimental group. 14 days after last injection from experimental and control animals were taken blood samples for haematological study determined the red blood indices: the number of red blood cells and hemoglobin, white blood: white blood cell count and leukocyte formula, and lysozime and bactericidal activity of blood serum. Further, the animals were monitored both during calving and postpartum period, and during subsequent artificial insemination and lactation, the duration of independent and manual separation of the afterbirth, the frequency of occurrence, form, duration of the course and outcome of specific diseases of the postpartum period (endometritis and early mastitis) were recorded. Fruitful insemination was determined based on the results of rectal studies. Based on these observations, the main indicators of herd reproduction were calculated, i.e. the insemination index (the number of inseminations per 36 fruitful), the duration of the period and the interbody period. As a result, the service period in the experimental group decreased by 113,7% relative to the control animals (178,2 days versus 2,3), the insemination index also improved in the experimental group – 3,8, against 1,6 in the control group. The average daily milk yield in the experimental group is 2,9 kg higher, and the live weight of calves at birth is XNUMX kg. A comparative analysis of hematological parameters of experimental and control cows obtained a higher level of markers of nonspecific immunity in the experimental group. Consequently, along with relatively rapid recovery of reproductive organs and shortening of the service period, the cows of the experimental group also had higher indicators of non-specific resistance compared to the cows of the control group.

Abomasal Displacement

Abomasal displacement is one of the most important disorders of the digestive tract in high-yield dairy cows. The etiology and pathogenesis of its occurrence has not been fully clarified to this day. The work examines calcaemia and phosphataemia in cows during the antepartal and postpartal periods and their connection with the incidence of abomasal displacement. The experiment covered 30 cows in advanced stages of gravidity. Blood samples were taken two weeks before expected parturition and two weeks after calving. In all blood samples (taken antepartal and postpartal), concentrations of calcium and an organic phosphorus were determined using a commercial test package (Bio-Merieux). Following parturition, left displacement of the abomasums was established in seven (23.33 %) of the 30 cows covered by the experiment (experimental group). The remaining 23 cows in the experiment were clinically healthy, they were placed in a group and represented control animals. The average value of calcaemia for the control group of cows during the antepartal period was 2.72?0.25 mmol/l, and of phosphataemia 2.04?0.25 mmol/l. In the same cows postpartum, average calcaemia values were 2.46?0.22 mmol/l and phosphataemia 1.85?0.29 mmol/l. The average antepartal value for calcaemia in the experimental group of cows was 2.51?0.25 mmol/l, and for phosphataemia 1.73? 0.22 mmol/l. The average values for this group of cows postpartally was 2.13?0.31 mmol/l for calcaemia and 1.43?0.24 mmol/l for phosphataemia. The differences between the concentration values for calcium and phosphorus obtained postpartally between the experimental and control groups were statistically significant. .
