The Types of Artificial Hormones in Cows
This article is not about organic grass fed cows that graze. The natural hormones that all animals produce are estrogen/estrdiol, progesterone and testosterone. This article is about that beef or milk that you get at major stores and restaurants. These are normally produced from hormone pumped up cows.
What are Hormones
Hormones are chemicals that are able to alter the functions of cells. Most hormones work as regulators for common body functions. It tells the cells when to speed up its function or when to slow down. They are naturally produced by the body, but can it be synthesized in a lab.
Scientists’ have found out how to significantly increase the size of animals with chemicals. Unfortunately, humans are the main consumers of such a daring experiment. There is no way to remove the types hormones in Cows before it is consumed. Heat, digestion and other processes do not totally eliminate the chemicals. It simply moves up the chain of foods.

How are Hormones given to Cows?
How are hormones given to cows?
There are two main methods of administering hormones in cows. The most basic method is by injection. The other method is by implants. The implants are normally placed behind the ears of the cows. Both injections and implants are administered based on the maturation of the cows. Implants are more popular because it is less hands on. Implants steadily release hormones in the cow over a preset time while injections have to be given manually.
This is a form of estrogen that is given to cows. It is specifically associated with the muscle/fat ratio of the body. It is the main reason why the flesh of cows has so much fat. This hormone in cows send a signal to fat cells to absorb more nutrients and water. The fat cells therefore become larger and may divide into more cells. The body is then intelligent enough to create blood vessels to continue feeding and servicing fat cells. This is the main reason why cows and humans affected increase in fat content.
Fat Cells or Adipose Tissues
It is important to remember that fat cells also store and release estrogen and progesterone. Once the adipose tissues become larger due to the effects of synthetic hormones, they will in turn produce these same hormones naturally.
This hormone is only naturally produced in the female body, especially when she becomes pregnant. The function of estradiol is to ensure that the body stores enough fat as reserve energy during the development of the baby. It should not be given to cows on a daily basis. The continuous administration of this hormone to non-pregnant cows disrupts the natural cycle of the cow.
This hormone is produced naturally in the human body. It plays a vital role in the menstrual cycle. Increased levels of progesterone are observed during pregnancy. A drop in this hormone normally signals the onset of labour. It signals to the body how long to keep gaining weight and works closely with estrogen.
This type of hormone in the cow is responsible for muscle growth. The larger the animals muscles, the more fat that the animal can store. Testosterone is mainly administered to beef cows. Especially, when they intend to slaughter a young cow and would like the cow to develop lean meat at an early age.
Zeranol is actually synthetic estrogen. It is specifically designed to be a growth promoter in cows and pigs. It is only used in the USA and Canada on medium to large cattle farms. It enables the animals to reach puberty stage at a much earlier phase. This is so that the animals can grow larger and at a much faster pace.
A series of studies have also showed that zeranol increases the risk of cancer in cows and humans alike. (reference: http://www.breastcancerfund.org/clear-science/chemicals-glossary/zeranol.html)
This hormone is actually secreted by a genetically modified fungus called Fusarium.
It is considered to be the most potent anabolic steroid in the world. Trenbolone acetate is similar to testosterone but far stronger. The most obvious side effect of the drug is constant aggressive behaviours. It is mostly used on beef cattles.
It is a synthetic form of progesterone. It is used to trigger an earlier onset of puberty along with estradiol. Melengestrol acetate is more potent than its natural counterpart. This hormone is effective in inducing accelerated weight gains when used in conjunction with testosterone and estrogen.
This hormone is mostly used on milking cows in order to increase milk production of each cow. It is also the most controversial of all the hormones. It is Developed and synthesized by the Monsanto Corporation. The chemical increases the output of milk from the mammary glands of the cows. It is also notoriously linked to the mad cow disease.
