Abstract

To maintain a body at sufficient physiological level the effective functioning of the immune system, which determines the resistance and immune reactivity of animals, is necessary. In our studies in newborn foals indicators of cellular immunity were mature. During the studying of foals of all ages were established the reduction of hematological parameters in animals months of age.

The use of immunomodulators prevents the immunodeficiency in animals. Immunomodulators introduction for animals normalizes T–immune system, in particular, increases the number of leucocytes in the blood, lymphocytes of certain populations, especially teofilin–resistant subpopulation of T–helper cells, increases the functional activity of lymphocytes.

Under influence of ribotan revealed a trend to the increasing of T–lymphocytes by 0.2 – 1.2% (0.4 – 2.3%), respectively in Purebred Saddle and Ukrainian Saddle breeds. Results of the content of T–helper and T–suppressor cells in foals blood after ribotan administration showed that the use of immunomodulators not only increases the number of T–helper cells, but restores the ratio T–h / T–s, which returned to the optimal rate (1.9). Analyzing the functional status of T–lymphocytes during the application of immunomodulators was found the probable increase of the number of activated T–lymphocytes in Purebred Saddle foals more than 2–fold (P <0.01) and trend to increase of these cells in Ukrainian Saddle foals. In relation to thermostable T–lymphocytes, was note that the trend to the most optimal level of these cells installed in foals after administration of ribotan (values within 3 – 4%). The increasing in number of thermostable T–cells more than 4% indicates an increase power of suppressor T–cells population, indicating the inhibition of T–helper cells, and therefore the production of antibodies. Thus, the use of ribotan in dose of 1 ml / animal for three days leads to an increasing in 1.4 – 4.5% of the number of leukocytes in the blood of experimental group of foals compared with control animals. Under influence of ribotan in the blood of foals increases cell (number of T–lymphocytes in 0.4 – 2.3%) and functional activity (T–active lymphocytes in 2.3 times; P < 0.05) T–immune system. Under influence of cycloferon in the blood of foals increases the functional activity of T–immune system (the number of T–active lymphocytes in 16.7 – 25%; P < 0.05).
