[Dynamics of blood proteins spectra in normal and diarrheic long horn cattle during early ontogenesis]

The contains of blood plasma protein fractions and immunoglobulines were studied in adult cattle and in new born calves (just new born and age of 1, 2, 5 and 10 days) by the 10% PAAG EP (0.1% SDS) and radial immunodiffusion methods. It is shown that protein bands of 140-160 kD and immunoglobulines (G1, G2, M) are absent at the moment of birth. The physiology level of gamma-globulines and IgG1 reach at 1 day of life, while IgM--at second. After colostrum breeding of just new born calves the speed increasing of total plasma protein and gamma-globulines fraction are lowest (in 2.7 and 1.7 times respectively) in diarrhoea animals in compare to the health one. The maximum level of IgG1 concentration forms in disease animals only at 10 days of age. On the date obtained it is concluded the presence such new born calves which have low level of small intestine developing and disturbance of immunoglobulines absorption.
