Compare to plants, animals have different kinds of hormones and other functions, consequently the use of hormones are more harmful for the development of animals than for plants because of all their parts and delicate organs and systems.
Animals fed with additives (which can be hormones and antibiotics) suffer from the following setback:
Use of hormones and antibiotics leave residues in meat, milk and eggs, which is objectionable.
Feeding with a low concentration of antibiotics may favor the proliferation of antibiotic resistant microorganisms, which could have serious consequences for disease control in humans and domestic animals like dogs, cats and birds.
However, it is difficult to develop intensive animal breeding without antibiotic feed hormones. Example:
“Recombinant bovine somatotropin (rBST) or recombinant bovine growth hormone (rBGH) is an artificial growth hormone produced using recombinant DNA technology (biotechnology) . When injected into cows, rBGH increases milk production 10-15 percent and even up to 40 percent in some cases. It is approved in the United States since 1993; however, its use has been controversial since farmers have started using it.” (Source Link 3)
The studies of this hormone have revealed that rBGH use in animal production causes problems. It shows an alarming rise in the number of deformed calves and increases in mastitis (a painful bacterial infection of the udder which causes inflammation, swelling and puss and blood secretions into milk). The presence of rBGH in a cow blood also stimulates production of insulin, which has been linked to colon and breast cancer in humans.
The European Union, Japan, Australia and Canada have all outlawed the use of rBST in animal production due to the animal and human health concerns.
Reports and studies also reveal that these additives can affect or alter the environment in multiple ways. For example, they affect natural habitats with the use of their hormones and antibiotics which can be passed to water and to the food of other animals.
It is argued that with the use of growth hormones, more plentiful quality meats can be sold for affordable prices. Growth hormones are often not well looked upon due to the use of synthetic hormones and also fears about the consumption of these hormones from the meat products. Due to the fact that synthetic hormones are unnatural, there are concerns about how they could affect the bodily functions of consumers. The long term affects of the consumption of synthetic hormones have not been thoroughly examined in animals or humans.
Conclusion:
Feed hormones. Though less expensive and safe from a human health point view, need more investigation and exploration about the active ingredients and the mode of their action so that their potential effects can be explained in terms of animal production and creation.

Yes, people started to realize that this kind of synthetic products are dangerous to animals, ecosystem and for us. Nowadays, the natural products are best or more safe. This fear for the synthetic products is enough for people to buy natural products.

ReplyDeleteDisadvantages of feeding animals with hormones
Post author: Andres Veloz
Is true that the products of the past are not the same products of our days. Almost all the people are more preoccupied for increase the production and they are using things that may affect the health of the people. As example of the things that they use are the antibiotics and the hormones. Hormones are used for control the development and the growth of the animal.
And is true that animals and plants have a different reaction for the hormones, because they have a different system.
There are obvious advantages and disadvantages with the use of such products. Farmers see hormones and antibiotics as a major advantage as the increase their production but this chemicals leave damage in the product and that production is consumed by the humans and that means that the health of humans is in danger.
Unfortunately this is true, farmers want to increase their products like eggs, milk, beef meat, pork meat etc.
ReplyDeleteSometimes they know the consequences but all they want is to sell their product to stores.
As we know, products from our grandfathers days or even our parents days, were still healthy, but today’s products are being altered by chemicals, that make animals to produce faster.
For example: These hormones make chicken to make their egg bigger, and if the chick is born it will grow bigger.
It all so makes cows to produce more milk faster and make them grow bigger.
An advantage is that farmers are going to sell their products faster and in a bigger percentage.
A disadvantage is that the food produced may have diseases because of the chemical and hormones used. This can cause seriously health problems.
In my opinion growth hormone makes grows up muscle and burn fat. In fact it will reduce the pot belly so it’s interesting in that way but there is a disadvantage which is also causes tumors to grow and complicates in the body, also there are the chances of getting cancer, particularly cancer somewhat increased.
ReplyDeleteI’m afraid I can’t really recommend it because is dangerous for the health of humans. So, we need to buy and consume natural products for have a good health and be careful to eat only synthetic that affect health.
In addition to what luis said, we can ceck it just by looking back two or three generations. For what my parents told me my great-grandfather and my grandfather, they were above the average height in this country.
ReplyDeleteThis characteristic, i can say that i don't see in my fathers generation, they are not taller than 1,70 m.
I think that the height issue is closely attached to the food that we consume, including all this chemical developed meat.
In comment to juan pablo’s post , it is true that more people are aware of the effects of sintetic hormones, but in my opinion at least in our contry there is not enough education on that topic, you can see it any day.
ReplyDeleteIt is enough that you go to a store like walmart, soriana etc; to see that allmost all the people take their food or meat in this case, without even reading the ingredients or what is it made of. Obvously this is something that concerns us all.
This kind of info needs more disemination to create a culture or a stronger interest on the things used to create the things we consume, because if you notice, most of the people only consume the more popular brands of food, trusting on the commercials etc.
So maybe if there was a stronger propaganda about this, people will really start thinking on what they are eating and what it will cause in their organisms.
Grassfed beef is a wonderful source of proteins and it is also included among the foods that boost HGH production.
ReplyDeleteBeef is an excellent source of coenzyme Q10 and L-carnitine. Some of the essential amino acids that beef is rich in play a role in the natural production of human growth hormone.
To experience the benefits of this meat, you should look for organic varieties. desiring hypergh14x review
You don’t need a partner to start going to counseling. If there is a significant other that wants to participate – great! Even if you’re currently single, you should consider therapy to restore your emotional balance.

Some people agree that male enhancement supplements work but they believe that older guys suffering from problems like erectile dysfunction (ED) will need to look for a pharmaceutical solution.
ReplyDeleteThis isn’t the case. Size increase pills contain substances that improve the functioning of the cardiovascular system and improve the flow of blood. As a result, they can be particularly beneficial for the guys suffering from ED. best volume website
