The sooner and more newly born calves eat colostrum, the more likely it is to survive, especially in summer and autumn, when the temperature and humidity are high, the season in which germs and viruses can easily grow and multiply is even more important.
The milk secreted by cows during the first 3 days of delivery is called "colostrum." Compared to regular milk, colostrum contains particularly high protein and ash content.
It was determined that the colostrum secreted within 2 hours after delivery of the cow contained 24.7% of dry matter, 1.17% of ash, 6% of fat, 11.3% of protein, and 38.23 milligrams of immunoglobulin per milliliter. With the extension of their delivery time, the above nutrients gradually decreased. The globulin contained in colostrum contains lectins and has the function of resisting pathogenic viruses. Vitamin A in colostrum is 10-30 times higher than that of normal milk, and the magnesium salt in the ash helps the excretion of meconium in calves.
