[Formation of levels of serum immunoglobulins (G1, G2, M and A) in fattened bulls].
The content of serum IgG1, IgG2, IgM and IgA was determined 80 young bulls, black and white aging 2-9 months, originating from individual and large farms. The animals were kept for 40 days in various environments (calf shed with a litter, calf shed of Bisprol 3000, adapted grate calf shed, pasteure) and then transferred into a fattening house of the farm Bisprol 3000 for 160 days. The level of serum immunoglobulins was determined by the method of radial immunodiffusion using specific antisera against bovine immunoglobulins of the own production. It was found that environment influenced the content of serum IgG1, IgM and IgA and depended on age origin of animals. However, the content of IgG2 depended only on age and origin of young bulls. The constant level serum IgG1 reached at the age of 6.5-7.7 months, IgM and IgA at the age of 5.0-5.5 months and IgG2 at the age above 9.0 months. The following mean of serum immunoglobulins in this time were found: IgG1 12.4 milligram, IgM 6.3 milligram and IgA 0.37 milligram.
