Art ificial induction of lactation has experimental value, but is not practical for several reasons. Injections must be given over a period of time on a daily basis, or tablet implants must be inserted. The methods are costly, labor intensive, give a low yield of milk, and do not produce income from the sale of the kids.

Milk is composed of protein, fats, sugar and mineral salts.
The osmotic pressure of milk is essentially equal to that of blood. The pH at 6.5 is slightly acidic. Milk contains higher levels of sugar, lipids, calcium, phosphorus and potassium than blood, but lower amounts of protein, sodium and chlorine. Proteins also differ, since milk protein is composed primarily of casein, with smaller amounts of albumin, globulins and others. Blood protein, is primarily composed of albumin and globulins.
