Inside Farming: Hormones Are Everywhere, Including In You

The beef with growth implants in cattle production
Many Canadians actively search for hormone-free beef for their next meal, but hormonal implants may not be the enemy. In reality, growth implants help beef animals convert feed more efficiently, which results in leaner meat and keeps the price of beef more reasonable for the consumer.

There is much buzz in today’s media about wanting hormone free meat. Can I let you in on a secret? There is no such thing. You see, just like humans, all animals have naturally occurring hormones in their bodies. What the consumer is actually trying to get when they ask for “hormone-free beef” is animals that are raised with no hormones outside of their own. Companies such as A&W are trying to scare consumers into thinking that their products are better because they are using beef that is raised without growth hormone implants.
Can I let you in on another secret? Implants are not the enemy. Growth implants are used to help beef animals convert feed more efficiently. This means the animals develop more lean meat and grow more on less feed. Beef animals that are implanted have increased weight gain from 5 to 23 per cent and convert feed to meat 3 to 11 per cent more efficiently than non-implanted cattle. By using less feed, costs are reduced for the farmer and beef is kept at a reasonable price for the consumer. There is also a smaller environmental impact when cattle are implanted, as farmers are using fewer resources to get them finished and ready for harvesting. A 2012 study published in the Journal of Animal Science stated that if we were to remove growth implants from our cattle production system, we would need 10 per cent more cattle, 10 per cent more land and feed, and 7 per cent more fuel and fertilizers to raise the same amount of beef.
You might be thinking that it’s great that implanted beef has a smaller environmental impact, but you still don’t want all those extra hormones in your own body. Well then, let me share this tidbit of information: 15 ml of soybean oil has over 28,700 nanograms of plant estrogen, while a 100 gram serving of beef raised with growth hormones has only 2.2 nanograms. Surprising, isn’t it? Studies have shown that there are greater differences in hormone levels between the different sexes of cattle then there are between cattle raised with growth hormones versus cattle raised without growth hormones.
