An experiment was conducted to compare the bioavailability of dl-alpha-tocopherol acetate (TA) with that of dl-alpha-tocopherol nicotinate (TN) when administered to sheep, as a single dose, either into the rumen or the peritoneal cavity. A total of 16 sheep were used in a factorial design, with 4 sheep/treatment at the interaction level. In addition, 5 sheep that received no supplemental alpha-tocopherol, were euthanatized at the end of the trial to provide baseline data for tissue alpha-tocopherol concentrations. Curves were fitted to the plasma alpha-tocopherol concentration values, taken over 180 hours after administration of the esters. Availability of TA was greater than TN, as evidenced by the significantly higher curve parameter values (P < 0.05) and tissue concentrations (P < 0.05). Route of administration had a marked effect on availability of TA (P < 0.001), but not of TN.

In order to increase egg and chicken meat production, poultry growth is critical. The purpose of this study is to see how well broiler chickens perform when provided different additives in their meals (trace minerals and vitamins). Nutraceuticals, in addition to providing nutritional requirements for birds, offer advantageous pharmacological effects, such as assisting in the establishment of normal state of physiological health, preventing various diseases, and thus improving production performance. The vitamins, polypeptides and amino acids, minerals, enzymes, and other nutraceuticals are examples. Vitamins are dietary substances that are required for vital cell functions such as cell development, growth, and metabolism process. Mineral nutrition is critical in broiler chicken production, with an emphasis on manganese (Mn), zinc (Zn), selenium (Se) and copper (Cu). Due to the availability of organic trace elements and today''s fast-growing birds, broiler chickens'' Mn, Zn, Se, and Cu requirements must be revised.

This study; It was aimed to compare serum and rumen content, trace element and serum vitamin levels and rumen content in indigestion cattle with healthy animals. Materials and Methods: The study was conducted on a total of 30 cattle, 10 healthy (control group) and 20 indigestion group. Indigestion diagnosis in animals was determined by anamnesis information, clinical and rumen content examination.Hematologically, there was no statistical difference between indigestion and control groups. Serum magnesium (Mg), calcium (Ca), zinc (Zn) levels of the measured trace elements decreased in the group with indigestion (p<0.05), while the levels of cobalt (Co) increased significantly (p<0.01). While there was a significant increase (p<0.5) in cattle with indigestion in rumen content Ca values compared to healthy cattle, serum levels were decreased (p<0.05). A positive correlation (p<0.01) was determined between rumen content levels of indigestion cattle and serum Mg levels of control group and rumen content of control group. In addition, a negative correlation was found between serum Ca and rumen content values of cattle with indigestion. In serum vitamin levels, Vitamin B1 (Vit B1) decreased statistically (p<0.05), while Vitamin B12 (Vit B12) was found to increase non-statistically (p>0.05).As a result, it was concluded that the decrease in serum Mg, Ca and Zn values in indigestion animals is important and these trace elements should be used in treatment.

This study was planned to determine the effect of certain vitamin applications on antioxidant and oxidant parameters in the osteoblast cell line exposed to sodium fluoride in vitro and to evaluate the protective role of certain vitamins against possible toxic effects of fluoride. Cells were replicated in vitro conditions with regular passaging 2-3 times weekly. MTF viability test was used to determine IC50 of NaF (5000μM) and proliferative doses of vitamins (Vitamin A: 10μM, Vitamin D: 10μM, Vitamin E: 60μM, Vitamin C: 100μM) for hFOB 1.19 cells. Cells were sown in flasks as so to be 106. The study groups were identified as control, NaF, vitamins and NaF+vitamins. After incubation for 24 hours, cells treated with trypsin were prepared by freeze/thaw method and MTT viability test, TAS, SOD, GSH, CAT, TOS and MDA analyzes were performed on these samples.In the hFOB 1.19 cell line, TAS levels decreased significantly in the NaF group (p≤0.05), but were close to the control group in NaF+vitamin groups with the exception of vitamin C. However, there was no difference between the groups in terms of GSH level and CAT and SOD activities when the control and NaF groups were compared. It was observed that TOS level increased significantly in the NaF group (p<0.05), decreased in the NaF+vitamin groups and were lower in the NaF+vitamin C and E groups than the control group (p <0.05). While OSI was the highest in the NaF group, no significant difference in MDA level was observed compared with the control group.Conclusion: As a result, it was found that NaF administration in the osteoblast cell line increased oxidative stress and decreased following vitamin application. It was found that the effect of NaF administration in the osteoblast cell line on cell viability was consistent with the oxidative stability and that the vitamin application conformably changed cell viability and oxidative balance.

Objective: The present study was planned to examine the changes in serum protein fractions of lambs with pica symptoms with electrophoresis. Material and Methods: The three study groups were the control group that included healthy lambs, pretreatment and post-treatment groups that included lamb with pica. Lambs with pica symptoms were then treated with a single capsule mineral complex orally and single dose vitamin complex. Serum protein fractions in blood samples were determined with cellulose-acetate electrophoresis.Results: It was determined that in terms of concentration, total protein, albumin and β-globulin, levels did not change, albumin percentage levels increased with pica, however reached control group levels with treatment and α1-Globulin and α2-Globulin levels reduced after treatment. Based on % gr, it was determined that α1-Globulin and β-Globulin did not change and α2-Globulin decreased. ɣ-Globulin level and percentage increased after treatment.Conclusion: Profiles of serum protein fractions may play an important role in the etiology of pica; it was suggested that the identification of serum protein fractions should be considered as a beneficial method in veterinary clinic for the detection, treatment and follow-up of certain diseases and certain nutrition-related conditions.

In the conditions of the Republic of Belarus there was determined the productivity and foraging advantages of fodder galega (Galega officinalis) in comparison with the traditional perennial leguminous grasses (alfalfa (Medicago sativa); alsike clover (Trifolium hybridum); cookshead (Onobrychis viceaefolia)) and influence of the analyzed crop of state and internal microbiota of agricultural animals. There was studied the qualitative structure of galega in accordance with the phases of crop development and its influence on physiological functions of animals. It is established, that in the conditions of northern region of Belarus the fodder galega provided the yielding capacity of dry matter of 11,3 t/ha that exceeded the indices of alfalfa on 13,9%, alsike clover - in 2,7 times and cookshead - in 2,1 times. By the third decade of May it formed 18-20 tons green mass that made it possible to feed animals on 10-15 days earlier, than with other leguminous grasses. High degree of leafage (65,7%) preconditioned its high nutritional value. Fodder galega has high level of calcium, potassium, phosphorus and some microelements: copper, zinc, manganese, cobalt. Studying of vitamin value of fodder galega showed that its green mass was vitamin-rich, had enough of irreplaceable amino acids. It was established, that hay of fodder galega had high level of the non-decomposed protein (68,6-71%) that was very important for feeding of highly productive cows. It increased the level of crude protein in experimental animals on 8%.

Investigation of vitamin supply of cattle affected by fascioles in association with strongylatosis of gastro-intestinal tract was realized in the conditions of the Republic of Belarus by an example of white-and-black 3-8 year old cows. Analysis of blood and blood serum of experimental animals showed that content of B1, B2, and E vitamins was lower in group of animals sick with fascioliasis and strongylatosis of gastro-intestinal tract. There were stated no changes in A and C vitamins content. Content of pyroracemic acid exceeded control indexes and was 22,0 +/- 0,173 mg/l. Content of vitamin A did not change and was 0,011 +/- 0,0012 mg/l for sick animals and 0,013 +/- 0,0043 mg/l at healthy animals. Content of vitamin C was different for sick and healthy animals: 1,685 +/- 0,190 mg/l and 1,93 +/- 0,294 mg/l, respectively. Research results proved that treatment of cattle sick with helminth infestation should be realized in complex. It was proposed to apply premixes and vitamin preparations containing B1, B2, as well as A, E, and C vitamins for the increasing of natural protection and for the creation of unfavourable conditions for disease agents

Morphological indexes in immune system organs of piglets which were vaccinated which were immunized by SPS vaccine (against salmonellosis (Salmonella), pasteurellosis (Pasteurella) and streptococcus) in combination with immunostimulative drugs and without them were studied in the conditions of the Republic of Belarus. Piglets of the first group were vaccinated against salmonellosis, pasteurellosis and streptoccocusis by SPS vaccine. Piglets of the second group were vaccinated by SPS vaccine in combination with vitamin C. Piglets of the third group were vaccinated by SPS vaccine with immunotstimulant sodium thiosulphate. The fourth (control) group of animals was administrated with normal saline. Animals were immunized twice, intramuscularly with 7 day interval and in dose 4 ml (primary), 5 ml (secondary). Vitamin С was added in dose 0,05g per head. Research results showed that immunization by SPS vaccine with sodium thiosulphate and Vitamin С activated the morphological reaction of immune system. Application of Vitamin С and sodium thiosulphate (30% concentration) in combination with SPS vaccine promoted the increasing of lymphoid nudels in lymphodnudus and lien, increasing of plasma cells quantity in 1,3-2,2 times, activation of micro- and macrophage reaction in 1,5-2,8 times in comparison with vaccinated animals
