Bovine somatotropin (bST), also known as bovine growth hormone, is an animal drug approved by FDA to increase milk production in dairy cows.
What are the side effects of bovine growth hormone?
In cows treated with rbGH, significant health problems often develop, including a 50% increase in the risk of lameness (leg and hoof problems), over a 25% increase in the frequency of udder infections (mastitis), and serious animal reproductive problems, such as infertility, cystic ovaries, fetal loss and birth defects …
Does anyone use rBST?

When was rBST banned?
The ban took effect on January 1, 2000, according to an article entitled, “The Regulation Of rBST: The European Case,” in AgBioForum, The Journal of Agrobiotechnology Management and Technology, Volume 3 /Number 2 & 3 (2000).
How is rBST administered?
rBST is administered to cows by injection beginning the ninth week after calving. rBST is carried to the liver where it stimulates that organ to produce Insulin-like Growth Factor (IGF-1), a protein hormone that aids in turning nutrients to milk.
How is bST produced?
Bovine somatotropin, abbreviated as bST, is a protein hormone produced in cattle by the pituitary gland located at the base of the animals brain. A hormone similar to bST is produced in all species of animals. This hormone is important for growth, development, and other bodily functions of all animals.
Why is bovine growth hormone bad?
According to a meta-analysis published in 2003, injecting cows with rBGH increases the risk of three important health conditions: Increased risk of lameness by 55% Increased risk of failing to conceive by 40% Increased risk of clinical mastitis (udder infections) by 25%
How does bovine growth hormone affect humans?
rBGH has no discernible effect on humans when consumed through either milk or meat products. Most, if not all, of the rBGH is destroyed during pasteurization and cooking processes, and the nutritional values and flavour of food from treated cattle is thought to be identical to its untreated counterparts.

Is rBST harmful milk?
There is, however, some agreement within the commercial dairy industry on the use of rBST being harmful to the cows, forcing them to produce more milk than is normal and safe. They argue that the synthetic hormone can cause calcium deficiency and result in bone weakness in some cows.
What is rBST and is it in my milk?
What is rBST and is it in my milk? RBST, short for recombinant bovine somatotropin, is a type of artificial growth hormone that increases milk production. It is illegal for use in Canadian dairy cows, but is legal in the USA. Following a 1990s survey, Health Canada identified that, when using rBST to increase milk production in dairy cows, there was no risk to human health, but there was a risk to animal health.
What are rBST treated cows?
At a Glance. Recombinant somatotropin, rBST (previously called bovine growth hormone), is a genetically engineered hormone injected into dairy cows to increase milk production. Milk from rBST-treated cows is used in dairy products including ice cream, butter, cheese and yogurt.
What is rBST treated milk?
In the US, the United States Department of Agriculture (USDA) determined that because rBST is a species-specific growth hormone, milk from rBST treated cows is identical to that of cows not injected with the hormone. As a result, rBST treated milk was approved for commercial sale.
