The immune system provides resistance of the organism against bacterial and viral infections in the body of the poultry. In the intestinal mucosa of eymeria it was secrete metabolic products, that are toxic to various systems and tissues of turkeys. Eymeria, parasitizing in the gut, inhibit specific phase of immunity presented by antibodies (humoral type), reduce the activity of sensitized cells (cell type), slow down nonspecific phase of immunity, represented by various immune cells. The rapid and complete recovery of functional state of the immune system in turkeys, affected by eymeriozic invasion it was found if brovitatoxide was given if the aggregate of the fruits of milk thistle.
Fruits contain group offlavius lignans named «Sylimaryn», acting immune stimulatory for the development of secondary immuno deficiencies state of body.
Key words: brovitatoxide, milk thistle, eymeria, immune system.

Introduction
Ukraine has recently slightly reduced the number of breeding and commodity farms of the turkeys growing. However, livestock of aforementioned poultry was significantly increased in adjoining the farm economy (Kobcova, 2001). A significant increase in the volume of poultry production can be achieved under the conditions of use of evidence-based system of doing the industry. Of particular importance is the question of a comprehensive study of infectious and invasive diseases considering exactly edge Epizootology. The importance of this issue in terms of efficiency of early diagnosis and the development of effective therapy is emphasized in a number of scientific papers (Mashke and Zakharov, 2002; Bohach and Taranenko, 2003; Timofeev, 2004; Khariv, 2011).
In early phylogenetic development for turkey poults there are different stress factors - inadequate feeding, inadequate housing conditions, bacterial infections, worms and protozoon invasion. This leads to decrease in body's natural resistance and inhibition of bone marrow hematopoietic function (Kotel'nikov, 1991; Dakhno et al., 2001). To improve the immune status of animals and poultry in practice of veterinary medicine different immune stimulatory drugs were used, namely KAFI. T-activin, leucogen, homotine, immunoglobulins, thymo-gen, kamizol etc. (Mashke and Zakharov, 2002; Khariv, 2011; Gutyj, 2013; Guberuk et al., 2015; Hariv and Gutyj, 2016; Khariv et al., 2016; Martyshuk et al., 2016; Nazaruk et al., 2016; Gutyj et al., 2016; Gutyj et al., 2017). The disadvantage of these drugs is that they are introduced parenterally, as is well known, poultry up to 3 months of age hardly carry over parenteral injection.
To improve the immune status of the organism of turkeys, secure and easy to use are vegetable preparations, that is added to feed. Their immune stimulatory action is not inferior to that of chemical drugs, and shows «softer» immune stimulating effect. To herbal preparations, showing a high immune stimulating effect should include Echinacea herb and fruit of milk thistle. At the moment such plants are widely studied and used in medical practice of humane medicine, however they do not pay due attention to the practice of veterinary medicine, particularly in poultry. According to foreign literature given issue has been little studied, but native in Ukraine in this direction was developed for the first time.
The purpose of our research was to study the effect of only brovitatoxide, and with the combined use with the fruits of milk thistle on normalization of the immune system of turkeys by spontaneous affection of eymeriozic invasion.
The criteria of therapeutic effectiveness of brovitatox-ide was dismissal of the turkeys organism from eymeria. Taking into account that sick turkeys with suppressed immune system, along with the use of brovita coccidia, milk thistle fruits was added with food to intensify cellular, humoral and nonspecific immunities. Besides, com-
pared the therapeutic effectiveness of both methods of turkeys treating for the occurrence of eymeriozic invasion.
Materials and methods
To investigate the influence of brovitatoxide and the fruits of milk thistle at normalization of morphological and biochemical parameters of turkeys immune system by spontaneous affection with eymeriozic invasion, three groups of research turkeys to 20 poultries in each group were formed.
Turkeys of the first group were treated with the help of brovitatoxide which was added at a dose of 2 g/kg of feed. The second group of turkeys were added brovitatox-ide 2g/kg and milled powder of milk thistle fruits of 2 g/kg of feed. Drugs were added with wet forage for 5 days in a row. The control group had normal blood parameters of the third group of clinically-healthy turkeys -analogue with compatible brooders. In each group it was noticed with ink 20 turkeys from which under the wing vein it was taken and after 3 and 5 days of treatment, and after 5 days after recovery. The blood was determined by the number of leukocytes, lymphocytes, T lymphocytes, B lymphocytes, lysozyme activity of serum, bactericidal activity of serum, circulating immune complexes, sero-mucoid level, phagocytic activity of neutrophils, phagocytic index and phagocytic number.
Results and discussion
The immune system of animals and poultry provides resistance of the body against bacterial and viral infections. At helmintozic and protozoonotic diseases functional immune system is suppressed and there comes a secondary immunodeficiency.
In patients of turkeys (Table 1), because of toxins action, allocating eymeria, before treatment leukocytosis was set. The number of leukocytes was 5.98 ± 0.56 g/l against 3.45 ± 0.14 g/l in clinically healthy poultry, that is 73.3% higher (P < 0.001).
On the 3rd day of brovitatoxide treatment their number decreased by 2 times, and on the fifth day was 12.3% greater than normal. Over 5 days after clinical recovery the number of leukocytes was 9% greater than control, which indicates the presence of inflammation of the mucous membranes in areas where eymeria parasitize.
In turkeys which were treated with brovitatoxide were slowly normalized the indicators of cellular immunity. Before treatment, the total number of lymphocytes was 62.2 ± 2.15 g/l against 88.6 ± 2.2 g/l in clinically healthy, which is 42.4% less (P < 0.001). On the 3rd day of treatment the number of lymphocytes has remained at a low level, slightly raised on the fifth day (period of clinical recovery) and on the 10th day (5th day after treatment) their number was 20% less than the control.

A number of lymphocytes populations returned to normal quite slowly. In particular, for the period of clinical recovery the number of lymphocytes was by 14.3% and T lymphocytes by 10.2% less than control values. At the same level, both of lymphocytes population were and on the fifth day after clinical recovery (Table 1).
At research of the quantities of humoral immunity In turkeys affected with eymeriozic invasion (Table. 2) it was set the decrease of antimicrobial activity of blood
serum and increase of CIC by 33% seromucoid by 89%, indicating the suppression of humoral immunity.
When applying brovitatoxide for the treatment of turkeys, for the period of clinical recovery (5-day), the indicators of humoral immunity were restored to normal values, but were lower than in clinically healthy poultry -bactericidal activity of serum by 13.9%, lysozyme activity of serum - by 19.1%, and indicators circulating immune complexes were high by 26% and seromucoid by 23.5% (Table. 2).

Lysozyme activity of blood serum in sick turkeys was by 24.5% lower than in clinically healthy poultries. At lower level it remained and on the 3rd -day, and slightly raised on the fifth day of treatment. But, and 5 days after clinical recovery lysozyme activity of serum was by 11% lower than the control.
Bactericidal activity of blood serum In turkeys before treatment was 21.6% lower than normal. It has increased by 3rd and 5 th day of treatment, but, for the period of clinical recovery was 13.7% lower than the control, and was normalized only 5 days after clinical recovery.
The level of circulating immune complexes in blood in serum of sick turkeys was 33.4% higher compared to the clinically healthy poultry. It decreased slightly on the 3rd and 5th day of treatment, but was respectively 28% and 21% higher than the control. On the 10th day of the experiment CIC levels in serum remained 11% higher than in clinically healthy poultry.
Seromucoid level in serum of sick turkeys amounted to 0,34 ± 0,05 mg/cm3, that is 88.7% less than in clinically healthy - 0,18±0,03 Mg/cm3 (P < 0,001). On the 3rd day of treatment, seromucoid level in blood serum was decreased in 2 times, compared with the level before treatment. More significant reduced the level of seromucoid
on the fifth day of treatment, but was only by 23.5% higher than the control. Within 5 days after clinical recovery, seromucoid level in blood serum of turkeys, treated with brovitatoxide, was the same as in clinically healthy poultry (Table. 2).
At research of nonspecific immunity parameters was set, that turkeys infected with eymeriozic invasion, phag-ocytic activity neutrophils was 15.9% lower, phagocytic index - by 19.7%, phagocytic number - by 22.0% less, compared to clinically healthy poultry (Table. 3).
The obtained results indicate the probable suppression of nonspecific link of immune system (Table. 3).
When applying for the treatment brovitatoxide, the value of FAL, FI, FN on the 3rd day were the same as before the treatment.
On the fifth day of treatment it was set clinical recovery of poultry. The indicators of non-specific immunity were increased, but were lower than the control: 12.3% Phagocytic activity neutrophils, Phagocytic index -13.4%, Phagocytic number - 8.1% (Table 3).
On the fifth day after clinical recovery (the 10th day of the experiment) turkeys state of immune system is not fully returned to normal. Lower compared to clinically
healthy poultry was Phagocytic activity neutrophils - by 8.4%.
The results of the research of brovitatoxide influence when applying collectively with milk thistle fruits on normalization of the immune system in turkeys, affected with eymeriozic invasion are shown in Tables 1-3.

On the fifth day after clinical recovery indicators of cellular immunity in turkeys, which were treated with brovitatoxide collectively with milk thistle fruits were the same as in clinically healthy (Table 4).
At research of humoral immunity status in turkeys affected with eymeriozic invasion was set up the decrease of lysozyme activity of serum by 24.5%, bactericidal
activity of serum - 21.6%, and increases in the blood serum level of circulating immune complexes and 33.4% and seromucoid - 88.7%. This points to a significant suppression of humoral immune system.
When applying for the treatment brovitatoxide in aggregate with fruits of milk thistle was found that at the 3rd and 5th day of lysozyme activity of serum was gradually increased and on 10th day reached the control value. Instead BASK was normalized at the fifth day of treatment (Table. 5).

non-specific immune system was found that the treatment of turkeys, affected with eymeriozic invasion, after applying of brovitatoxide in aggregate of milk thistle fruits phagocytic activity of leukocytes reached normal values at the 10th day of the experiment, i.e. 5 days after clinical recovery. Deserves positive assessment by the fact that at the fifth day of treatment were normalized the values of phagocytic index and phagocytic number, which is an indicator of sufficiently high activity of leukocytes (Table 6).

Consequently, as a result of the research we found that in turkeys infected with eymeriozic invasion occurs inhibition of cell and humoral immunity and reduces nonspecific resistance of organism, leading to the development of secondary immunodeficiency.
Conclusions
According to eymeriozic invasion, when applying for treatment brovitatoxide, for a period of clinical recovery, the state of cellular and humoral immunity was significantly improved. But, at 5th day after recovery at 20% below normal values was the total number of lymphocytes and at 10% the number of T and B lymphocytes, indicating a partial recovery of the functional state of cellular immunity. The low lysozymic activity of blood serum, and a high level of circulating immune complexes in it at 5th day after clinical recovery points to a partial recovery of the functional state of humoral immunity link. The low phagocytic activity of neutrophils confirms it.
The rapid and complete recovery of functional state of immune system in turkeys, affected with eymeriozic invasion was established if brovitatoxide was given aggregately with fruits of milk thistle. The fruits contain group of flavolignans called «Sylimaryn», acting immune stimulating for the development of secondary immune deficiencies state of organism.
