“…The biodefense system of newborns is immature at birth. In particular, bovine colostrum is important for newborns to protect them from infectious diseases [2,3,15,16,18]. In addition, an increase in PMNL phagocytic activity in breast-fed infants has been reported [13,17].…”

ABSTRACT. Bovine milk contains various immunoreactive components, and the activation of polymorphonuclear leukocytes (PMNLs) function in breast-fed infants has been reported. In this study, the effect of milk on the oxidative burst of bovine PMNLs was investigated in vitro. When PMNLs were incubated with 0.1% colostrum or normal milk, the oxidative burst induced by serum-opsonized Staphylococcus aureus was enhanced, and the enhancement declined dose-dependently. The enhancement of the oxidative burst by milk was not due to opsonins but the priming activities. Also, the phorbol 12-myristate 13-acetate (PMA)-induced oxidative burst increas ed after incubation with 0.1% colostrum, but the colostral enhancement of the oxidative burst was unaffected by the incubation time. These results suggest that bovine milk contains oxidative burst promoting factor(s). KEY WORDS: bovine, colostrum, normal milk, oxidative burst, polymorphonuclear leukocyte.

“…When studying the relationship between the immune globulin level in the blood serum and the mortality of calves McEwan et al (1970a) found that, if the immune globulin level was 0-10 units, 30.7 % of calves died of septicemia whereas the death loss of calves was not observed if the immune globulin level exceeded 20 units. It has recently been found that at lowered immune globulin levels a respiratory syndrome was observed more frequently (Thomas and Swan 1973).…”

J agos P., Bouda J.: Protein Metabolism in Cows and their Calves Fed from Buckets. Acta vet. Brno, 49, 1980: 59-66.The level of total protein, protein fractions, immune globulins in blood and colostral serum of 40 cows and in blood serum of their calves up to the age of 3 months were determined. No significant differences in the concentration of total proteins and their fractions in blood serum in cows ante and post partum were found. The concentration of total protein in colostral serum was found to be significantly higher (P < 0.01) than that in blood serum of cows.The average value of total protein in blood serum of calves prior to the ingestion of colostrum was 41.7 gil. The gamma globulin values in blood serum of calves reached the maximum after 24 hours upon the first ingestion of colostrum. The lowest gamma globulin values were found in calves of 3 -6 weeks of age. Immune globulins correlated with gamma globulins and decreased below the standard in almost 50 % of calves 3 days old.The absorbed gamma globulin from colostrum participated in increasing the total protein content in blood serum of calves. Besides the determination of serum gamma globulins and immune globulins the total protein determination by the refractometric method can therefore be used for the diagnosis of hypogammaglobulinemia in calves. The level of serum immune globulins should not fall below 20 units and should be measured from the 2nd to 7th day of calf age. Late and less frequent colostrum ingestion was found to be one of the causes of low immune globulin levels.

“…Total serum immunoglobulin concentration (g/L) was determined using the zinc sulfate turbidity test (McEwan et al, 1970). These results were then reduced by a factor of 0.09 to provide the IgG-only content of the serum (Larson et al, 1974).…”
