9

d. (Colostrum)

-The best way to prevent fatal septicemia in young calves is to make sure that they get enough Colostrum, since colostrum contains bioactive components with immune enhancing properties: Immunoglobulins, lactoferrin, lysozyme, lactoperoxidase, α-lacto albumin, β-lactoglobulin, or fat that carries important vitamins and polyunsaturated fatty acids. 

-Colostrum coagulates on heating due to higher concentration of Albumin and Globulin

Other Factors related to Calves:
