DYNAMICS OF FORMATION OF NATURAL RESISTANCE OF KARAKUL SHEEP LAMBS CONTAINED IN VARIOUS ECOLOGICAL CONDITIONS

The dynamics of the formation of the natural resistance of Karakul sheep lambs contained in various ecological conditions were studied. The titer of anticolibacterial antibodies and the titer of normal hemagglutinins containing immunoglobulins G and M in the blood serum of Karakul sheep lambs of 1-3-5-7 weeks of age served as indicators of natural resistance. The influence of the invasive process on the indices of the natural resistance of Karakul sheep lambs is determined. The research results show that the invasive process significantly inhibits the natural resistance of Karakul sheep lambs.
