The first colostrum-fodingtime often birth, serum gamma-globlin, IgG, IgM and IgA levels in the serum and colostrum were determined in 73 Holstein-Friesian calves. Inter relation was observed among them, as well as the subsequent occurrence of clinical diarrhea in the first month of life.
Significant positive correlations were observed between the colostrum-feeding time and the health of the animals; the serum gamma-globlin, IgG, IgM and IgA levels and the health of the animals; and the serum gamma-globlin, IgG and IgM levels and the colostrum-feeding time.
The serum immunogloblin levels of the calves were influencedmore distinctly by the colostrumfeedingtime than the colostral immunogloblins levels.
The calves had to be fed colostrum in the first hour often their birth to get high-level serum immunogloblin for defense against neonatal diarrhea
