Many people make their living off of raising dairy cattle. They choose Jerseys, Guernseys, Holstein or other breed known for good production. Jersey and Guernsey produce milk high in butterfat. Holsteins produce larger amounts of milk.
Cow's milk is the food for calves. It contains IGF-1, an insulin-like growth factor which is identical to that of humans. This is to make the calf grow quickly. Once the calf is weaned, it never drinks the milk again. Humans, on the other hand, drink it instead of human milk or in addition to it. When we make milk into cheese, it increases the IGF-1 by 10; Ice cream by 12 and butter by 21. High levels of IGF-1 have been implicated in increased cases of breast, colon and prostate cancer. Cow's milk contains a total of 59 hormones designed by Yahweh to nurture the growing calf. Humans have IGF-1 in smaller amounts.
In addition to IGF-1, cow's milk contains anything that is on the plant or the plant took out of the soil. This includes herbicides, pesticides, dioxin and radioactivity. Add to that over 50 antibiotics, blood, pus, bacteria, feces and viruses. recombinant Bovine Growth Hormone (rBGH) is made by Monsanto, who also makes Agent Orange, DDT, Roundup and other products. This causes the cow to produce more milk and can result in higher rates of mastitis.
One out of 10 cows in America is infected with Mycobacterium Avium subspecies Paratuberculosis, a obligate pathogenic bacterium found in soil or water. It causes Johne's (Yo-nees) disease in cattle, which affects the ilieum and causes weight loss. This disease can also infect humans and is implicated in Crohn's disease. The strain type is ATCC 19698. It requites a long antibiotic regime.
Now we have cows that are carrying Methicillin-resistant Staphylococcus Aureus and it is found in unpasteurized milk.
Finally, we have people who are allergic to cow's milk. Immediate symptoms: hives, wheezing, vomiting or anaphylactic shock--swollen throat, flushed face, constricted airways or itching with a drop in blood pressure. Hours later: diarrhea or loose stools with blood, stomach cramps, coughing or wheezing, headaches, runny nose or watery eyes, sinus drainage or headache, itchy skin around the mouth or in babies: colic.
