Why I am abandoning my non GMO chicken feed…for now.

A few months after this post and ever since we have been able to feed our animals non GMO feeds made by Profile Feeds in Paarl – Angus, 16 February 2021

In the five years that I have been farming this is the most depressing thing that has happened to me.

If you would rather read about the uplifting things we do on the farm like Carbon sequestering beef, or what an Eggmobile is or why we have planted over 4,000 trees into our pastures just this winter or what inspires us in our work in the vineyards then click on the highlighted green writing. If you want to understand why I have had to change my chicken feed then wade on.

First and foremost I am not changing food because the maize is non GMO, but because there is mycotoxin in the maize and the mycotoxin inhibitor is interfering in the gut of our chickens resulting in deficient nutrient uptake which means the eggs are the normal pale junk that masquerades as eggs and not our usual blaze of orange.

The photo above was taken today. The pale egg on the left is a week old, the one on the right was laid today. A week ago we changed one variable only, namely the feed ration for the Eggmobile that those eggs come from.

Before we get into the chronological record lets dwell briefly on GMO’s.

1. The entire premise on which Big Ag and biotech is based is false. “How are we going to feed the 9 billion in 2050?” They ask. “Only with technology” they answer. If these idiots stopped believing the propaganda and looked beyond the soundbites published in the magazines (which are funded by massive advertising by the biotech companies) they would see that we produce enough food in the world to feed 12 billion people. There are also equal amounts of people dying of obesity and starvation and yet their answer is to produce more of this food that makes humans and the planet sick. I guess if the only tool in your toolbox is a hammer then every problem you see is a nail, despite your posturing about being a scientist.

2. GMO’s give power to the corporation and not to the farmer. A corporation has never been more trustworthy than a human being and it never will. Here is a short worthwhile watch about the need for industrial agriculture to feed the world…or not as the case is.

3. There is also an autism epidemic. This started around the same time GMO grains were introduced into the food chain. This amazing research looks into the role that Glyphosate (the active ingredient in the herbicide which is the foundation of the GMO story) plays in autism. Please click here and read this. 

Anyway for all these reasons and more I wanted to have my hens on a non GMO ration. Our feed company (Profile Feeds) very kindly agreed to accomodate me on condition that I sourced the two primary ingredients, namely maize and soya. I bought these in May and in June and this, in hindsight, is where my problems started. I could not use normal storage facilities as they are contaminated with GMO grains. Hence my grains needed to be stored in bags.

The first non GMO grain to be abandoned was the soya. Here is how and why.

With soya there are basically two routes you can follow to get the grain into a edible form. Route 1 is to extrude the soya which becomes full fat soya. Route 2 the soya grain goes through a process where it gets broken down into soya oil and soya oil cake. We had to go for Route 1 because no soya mill would do the second process for us because they could not prevent contamination with the GMO soya. We were very kindly accomodated by Afresh Vention.

For the first month on the 100% non GMO mix the hens did really well. Egg production was good. However after the second time, on the 9th of August, they got the feed the egg production collapsed. We discovered that the full fat soya was going rancid. We only used 3 tons at a time but had to extrude 10 tons at a time as the machines cannot handle less. Full fat soya lasts at best 4 weeks before going rancid and we had 12 weeks of stock. We then stopped non GMO full fat soya and went back to GMO soya oil cake. Within a week of this new ration egg production was back up and for the next two months our hens did fabulously on a 85% non GMO diet.

In early October our hens started dying. After much veterinary investigation it was determined that there was a mycotoxin in the feed and we immediately added the mycotoxin inhibitor as it was our non GMO maize (which was/is stored in 1 ton bags on the floor of the feed company) in which the mycotoxins had developed. Our hens stopped dying and egg production started climbing again. However the eggs started getting paler. At first I ascribed it to the fact that the cattle had been grazing ahead of the chickens.

In the photo below, the cattle are between our youngest and some of the Eggmobiles. They lead the Eggmobiles up the hill.

However this was not the case as the grass grew and still the yolks got paler. We did blood tests that revealed no underlying illness in the hens. Their egg production kept climbing. Eventually clients started commenting that there was a problem with the eggs. Our client list is at the top of this page, click on SOURCING PRODUCE. None of the poultry professionals that we consulted could help and even our chicken team (photo below) of Thobelani, Menzi, Douglas and Victor was stumped.

One of my mentors, Tommy Dyzel a.k.a Mr Quantum Agriculture did some investigative work which indicated gut interference from the mycotoxin inhibitor. Last week we started feeding the one group of hens a normal free range ration. I.e. the same as our hens were getting but with normal GMO maize and obviously without the mycotoxin inhibitor. The result is the first photo in this blog.

What now? I have to go back to the world of Monsatano until I can rob a bank to build two silos in which I can store my non GMO (eventually biodynamic) grains and build a plant to process the soya into soya oil cake and soya oil. This is the price for living in the only country in Africa that has approved GMO grains.

I promise not to end the year on this depressing post.

    Hi- thanks for the insightful article on why non-gM feed for chickens is problematic in South Africa- I have been trying to get my local feed producer to source me some non GM feed without luck so far. I am an urban chicken “farmer” with a flock of 12 Australorp hens and really would like to have non-GM eggs to feed my family- the reason we keep hens is to have home produced eggs. Please could you let me know if you find a solution to sourcing your feed? I have just come back from Austria where all “bio” eggs have a guarantee written on the box that the hens have only been fed non-GM feeds- so upsetting to see that is not happening here! Anyhow, all the best with your farming, Jenny

    Firstly, I love your work, thank you!
    This is indeed depressing!:-( I want to get chickens, but only if I can find non gmo feed…which seems to be impossible?!
    A question: Do chickens really need to be fed soya, for example?
    And: how much money do you need to build your silos?

    Hi Angus

    Where did you source your non-GMO corn from? We would like to feed our chickens Non-GMO containing feed, but this is impossible, as you yourself know!

    Kind Regards

    after reading your depressing news about gmo i would like to encourage you to make non gmo silos .
    i and many others will buy from you non gmo chicken feed .(please don’t rob the bank)
