We get Ginnu/colostrum milk after cow gives birth to a calf. I got Ginnu/colostrum milk from a village man, as per his saying, they give the first milk to temple and then distribute among themselves.
Colostrum Mlik, Ginnu haalu in kannada, kharvas in marathi, junnu paalu in telugu.
Ginnu/Colostrum Milk is very rich in proteins, vitamin A, and sodium chloride, but contains lower amounts of carbohydrates, lipids, and potassium than mature milk. The most pertinent bioactive components in colostrum are growth factors and antimicrobial factors. The antibodies in colostrum provide passive immunity, while growth factors stimulate the development of the gut. They are passed to the neonate and provide the first protection against pathogens. Colostrum is known to contain immune cells and many antibodies.
We can get colostrum milk/powder in stores and I do not know about the quality. I have not tried. I prefer fresh milk.
Today I am preparing traditional method of preparing Ginnu/colostrum milk.
