All Canadian provinces which are involved in the backgrounding and/or feedlot industry--from British Columbia to Ontario and everywhere beyond and in between--are allowed to inject feeder/finisher beef cattle with hormones to obtain better growth and feed efficiency.
Growth hormones are mainly used in organisms, especially in livestock. An example would be that a farmer may want to increase the production of lean meat. So, he inserts growth hormones in cattle.
The growth hormones and antibiotics used in the raising of cattle and other meat animals are not passed on to you. They are denatured (changed) when they are cooked and do not act on your body.
Depends on the ranchers themselves and what market they are targeting, and what cattle they're feeding. Cattle fed on a feedlot diet (which comprises of 97% of the finisher/backgrounding herd in the USA) are not fed hormones, but are given growth hormones via implants in the ears. Heifers, on the other hand, are fed hormones to keep them from going into heat all the time. Angus cattle on such a diet are fed primarily corn-grain-silage mixture to fatten them up prior to slaughter.
The function of growth hormones is the stimulate growth in the body
Growth Hormones, Thyroid Hormones, Sex Hormones and Mechanical Stress

Growth hormones?
The hormones that most dramatically affect breast growth are estrogens.
The answer is none. Just like Diabetics they have a level sugar and insulin. When sugar is so high they cannot balance out the insulin and become diabetics. The same meaning stands for Growth hormones and Anti Growth Hormones. They body produces growth hormones while at the same time Anti growth Hormones. There is no connection between the two.
Growth is affected by 1. Growth Hormone 2. Thyroid Hormones 3. Insulin 4.Parathyroid Hormone 5. Calcitriol 6. Reproductive Hormones
One reason would be the growth of humans, leading to the growth of cattle for food
The hormones used to fatten beef cattle really depend on the company who makes them and the gender of the cattle you are wanting to use them on. Most people state that "growth hormones" are used to fatten beef cattle, but this really isn't the case. Here's a few of the common hormone implants used in fattening beef cattle and what they comprise of:Ralgro: contains ZeranolRevalor: contains Trenbolone acetate and EstradiolSynovex C and Snyovex S: Progesterone and Estradiol benzoateSynovex H: Testosterone propionate and Estradiol benzoateNote that none of these implants contain any form of growth hormone or rBGH.The availability of such implants can be found at your local farm and ranch store, or can be purchased from your local large animal veterinarian.See the related links below for more information.
