Hormones in the Animal Agriculture Industry.

Hey everyone! I just would like to preface this by saying that over the next few days I will have the amazing opportunity to meet and interact with Temple Grandin. Dr. Grandin is an amazing influential character in the animal industry. She specializes in animal welfare. If you do not know who she is, please take a second and look her up before reading this blog.

Now, onto the important matter here. Hormones are a hot topic in the food animal circles, whether you’re a consumer, producer, retailer, etc. I want to state that I do not want to tell you how to think. I really want to give people the facts and maybe a small part of my opinion. Before we can truly believe something, we must first know the hard facts. Since this post is such a big deal, I will start by stating my opinion so that you know where I stand and can determine what parts of this blog are facts.  I believe that hormones in animal agriculture are safe to humans, increase productivity, and are efficient to the industry. However from an animal welfare standpoint I do not agree with use of added hormones.

Let me start with the basics. The first thing you need to know is the difference between beta-agonists and hormones. A beta-agonist is basically a non-hormonal compound which releases epinephrine (adrenaline) and converts extra energy to muscle, in turn increasing growth efficiency. These animals, being pumped with adrenaline are increasingly skittish, jumpy, and stressed. It would probably be similar to someone who is on methamphetamines (this is my comparison, not a fact). In fact, Dr. Grandin found so many problems in packing plants when a beta-agonist called Zilmax© was introduced that all major packing plants quit using it. Read that story here. Beta-agonists are used in large scale cattle and pork growing stages. Smaller feedlots tend to avoid beta-agonists. Hormones are natural to all animals, so that when added to the diet, implanted, or injected into the animal, it does not frighten them like high dosages of epinephrine do. However increased dosages of hormones to enhance production efficiency. Hormones are not used in pork or poultry products.

In dairy cattle, the most common hormone that we hear about is bovine-somatotropin (bST). It has been proven that this hormone, which increases milk production, is completely safe for human consumption. The reasoning behind this is that bST is a protein based hormone and is biologically inactive in the human body1. First, any residue from this hormone is mostly eliminated by pasteurization of the dairy product. Second, any bit of hormone left in the product, once consumed, is completely digested by the human gastro-intestinal tract and is turned into amino acids. This makes the hormone completely safe to consume and causes no increased growth or faster puberty in humans. However, in 1999 the European Union banned use of bST due to animal welfare concerns. The U.S. is the only major exporter to use bST in dairy cattle. Read about the court case on bST here.

As much as I hate to admit it, I think that the animal agriculture industry has made a mistake allowing hormones to be our easy way out. I believe that the use of hormones and beta-agonists are economically motivated. I also believe that if the industry chose to select for better genetics, larger animals, leaner animals, then we wouldn’t need the use of hormones. The problem with this is that it is expensive, takes a long time, and is not as efficient. Use of these additives is cheap, (although the people making them sure do make a lot of money) it helps produce more meat with less animals and less feed, and the results are somewhat immediate. All of these hormones and beta-agonists have also been approved by the FDA when given in the correct dosages. Producers will be hard-set in their current ways and unlikely to change especially when what they’re doing is government approved.

I would like to hit on one last thing before I go. As consumers we need to educate ourselves and our fellow consumers. I want to point out that sometimes we make things harder on ourselves. While worrying about what meat is the best to pick, keep in mind that NO poultry producer uses antibiotics after the second day of life. It is illegal. Hormones are NOT added in poultry or pork. This is not to say that any producer or retailer is lying to you. Just be aware that there truly is no difference in “antibiotic free”

chicken and conventional chicken. Please share with your friends and help them become savvy shoppers and consumers. Let me know what you think by commenting below!

The Agrarian's Alcove Celebrates Black History Month

Here at the Agrarian’s Alcove, we absolutely love to celebrate ag. I mean LOVE to celebrate it. It’s the basis for life and the world’s economy. February is Black History month and so we’d like to dedicate our celebration to the amazing contributions that African Americans have made to our industry. First thing’s first-does anyone here like potatoes?(Read our post about the best potatoes here ) What about potato chips? The salty, savory, crunchy snack that we all fall for was created by George Crum , a half African American-half Native American chef. After a customer’s complaint in 1853 that he cut his fried potatoes too thick, Crum responded by slicing the potatoes as thinly as possible, and fried them until they crunched. The restaurant goer (not surprisingly!) ended up loving the crispy potatoes and Crum ended up opening his own restaurant. Crum never marketed his snacks, but snack food junkie William Tappendon began putting these chips on the shelves of grocery stores in 1895...

The Agrarian's Alcove Celebrates: Earth Day

Good morning Agrarians!! Happy Earth Day ! Hopefully you are out celebrating with fun Earth Day crafts and free activities! I always loved Earth Day activities as a kid. So when I started hearing about the activities this year, I wondered how this all got started. It’s a huge event that happens each year, and is celebrated in more than 190 countries! More than one billion people celebrate Earth Day. If we go back to the very first Earth Day, in April 1970 we see lots of protesters with their signs held high. The 70’s were a time of great protests. If you look at pictures of the first earth day, you will see children wearing shirts that say “Let me grow up!”, large handmade signs with snappy slogans, and people doing generally weird things...like walking around in gas masks. So obviously this was a classic grassroots protest. If you think our world is dirty now, you should have seen it before Earth Day. Rivers were LITERALLY catching fire when someone tossed a cigarette into them...

Ag in the Time of Pandemic: Cutting our Losses

The recent turn of events in our world has frightened many people. The economy is plummeting. The rate of unemployment increases daily, and along with these employment concerns, many have been concerned at some point about the supply in our American grocery stores. Our world has been tested time and time again with pandemics causing major pandemonium. Agriculture has withstood the trials of these viruses, and will continue to do so this time around. Farmers will continue to work and provide for the world. So just how does agriculture function during the time of pandemic? We will take a look at this in a series called Ag in the Time of Pandemic. This is the first post of the series- Cutting our Losses. One of the most frustrating things that we have heard about in the agriculture industry throughout this time is the amount of waste that has occurred. Of course, we’ve always been conscious that America produces some of the largest amounts of food waste in the world. You can read about th...
