Genetic engineering in feed additives.
Various additives and enzymes added to animal feed can be produced with the help of genetically modified microorganisms. For example Vitamin B2, vitamin B12, or biotin for animal health, various amino acids for improved feed quality, enzymes for improved breakdown efficiency, and colouring, beta carotene, e.g. for salmon. Despite methods that are becoming more and more sensitive, tests have not yet been able to establish a difference in the meat, milk, or eggs of animals depending on the type of feed they are fed. It is impossible to tell if an animal was fed GM soy just by looking at the resulting meat, dairy, or egg products. The only way to verify the presence of GMOs in animal feed is to analyze the origin of the feed itself. GMO Watch. Information on GMO and GMO foods.
