No. Hormones use in poultry production in Canada is illegal. In fact, it has been banned for over 50 years.
There are a lot of good reasons as to why hormones aren't used in poultry production.
Growth hormones aren't effective. It has been shown that giving growth hormones does not lead to increased growth in chickens. In a similar vein, injecting growth hormone into humans will not lead to development of a winning basketball team. Growth is an extremely complex combination of metabolic functions, depending on a wide array of endocrinological signals.
Administration of hormones would be extremely difficult. Growth hormone is a protein and if consumed orally, they would be quickly be digested in the same way as protein from corn or soy. Even if a positive effect were likely from growth hormone , it would need to be injected into chickens on a very frequent basis. The logistics of injecting hundreds of thousands of chickens with hormone illustrates the impossiblity of this scenario.
It would be expensive. Chicken growth hormone is not produced commercially, its cost would be extremely high. If one (1mg.) were to be administered to a broiler, the cost would be far in excess of the value of the chicken itself. Obviously, this makes no commercial sense.
Negative impact of chicken performance. The modern broiler has been genetically selected to grow rapidly and occasionally encounters physiological limits. Like humans, a “growth spurt” is usually accompanied by joint inflammation and other problems. Chicken farmers actually monitor, and sometimes limit growth rate and to decrease the incidence of lameness, heart attack and ascites. It would be highly counterproductive to suddenly force a higher rate of growth on broiler chickens.
Hormones are simply not needed. The rapid growth of broilers is very easy to explain without resorting to hormones. Through genetic selection for the past several decades, birds have reached a specified market weight one day earlier per year. The growth of modern broilers is a logical consequence of slow but consistent improvements in genetics, nutrition, management and disease control.
