Changing from GMO to Non-GMO Natural Soy Animal Feed: Farmers See Big Difference

Changing from GMO to Non-GMO Natural Soy, Experiences from Denmark

Healthier, more productive pigs, more profit, and much less birth deformities; an important lesson for all farmers not to use GMO feed or glyphosate on their land

My farm “Pilegaarden” (Willow Farm) is an average Danish farm in the small village of Hvidsten. Our pigs are raised accordingly to United Kingdom regulations for pig housing, and exported to the UK for consumption. Inside the pig farm is a straw-based system for the sows as well as a standard farrowing house.
I had read about the effects that GM feed has on rats in lab experiments (see  GM Soya Fed Rats: Stunted, Dead, or Sterile, SiS 33), so I decided to change the feed from GM to non-GM soy in April 2011 without telling the herdsman on the farm. Two days afterwards, he said to me: “You have changed the food.” He always notices whenever there is any problem with the feed and tells me. This time was different. Something very good was happening with the food as the pigs were not getting diarrhoea any more. The farm was saving 2/3 of the medicine or £7.88 per sow; not just my farm but three other farms in Denmark that switched from GMO to non GMO feed have also seen the same. Medication after the changeover in the weaners barn also went down dramatically by 66 %, with one type of antibiotics not being used since.
The sows have higher milk production; we can tell because the sows are suckling 1, 2 or 3 more piglets and have more live born pigs, on average 1.8 piglets more per sow. They wean 1,8 pigs more pr. litter, and have more live born pigs. We have seen a certain aggressive diarrhoea disappear altogether that affected young piglets in the first week of life, killing up to 30 % of the pigs. It has completely gone for over 3 years. Sows no longer suffer from bloating or ulcers and they also live longer in high production, only dropping in effectivity after 8 layers compared to 6 on GM soy.
So, a change to non-GM soy makes the herd easier to manage, improves the health of the herd, reduces medicine usage, increases production and is very profitable.
Severe birth deformities in piglets
Deformities in the pigs used to be very rare and I used to be proud to send Siamese twins to schools for classes because it would only happen one in a million. But then they became too frequent. So I read a lot on the subject and my suspicion fell on glyphosate. I read how glyphosate had been shown in scientific studies (see  Lab Study Establishes Glyphosate Link to Birth Defects, ISiS 48, ) to cause deformities and noted it was the same type of deformities that I was seeing in my pigs… read more here
