The EU suspends the specific additive, vitamin B2, as it is not within the adequate regulation guidelines for Genetically-Modified Organisms

Like human beings, animals need a balanced diet that can provide their daily body needs. Some nutrients require an exogenous supplement to be part of a balanced diet for livestock, by each species and growth phase. Among these nutrients, some vitamins are commonly added to diets, like vitamin B2. Vitamin B2 belongs to a group of water-soluble vitamins and is present in all living tissue. It acts directly on the metabolism of various enzyme systems, as well as being important in the electron transport of the respiratory chain and the metabolism of amino acids, carbohydrates, and oily acids.

Recently, the EU suspended the sale of a specific additive, vitamin B2, produced from Bacillus subtilis KCCM-10445, which is a genetically-modified bacteria. The additive was found to be non-compliant with the regulations required by laws regarding GMOs (Genetically-Modified Organisms) and was submitted to several laboratory tests. The demands concerning food safety are a growing reality around the world and the search for natural additives that provide what animals and humans needs have been steadfastly pursued by industries, research institutes, and authorities that aim to guarantee public health.

The vitamin B2 provides critical functions for the maintenance of cells and tissues, being a harmful deficiency to the organism of animals.

Liliana Longo Borges Ph.D., Animal Scientist, and Research and Development (R&D) Analyst, ICC Brazil, says the deficiency of vitamin B2 causes stunted growth in young animals, apathy, lack of appetite and mucus problems. “Some symptoms, however, differ from one animal to another. Horses, for example, may show periodic night blindness. In pigs, there are skin conditions and inflammations, diarrhea and intestinal phlegm, reproduction problems (high fetus mortality or premature births). In birds, the most characteristic symptom is curved-finger paralysis, which causes movement difficulties. In hens, there are hatching disorders and embryonic problems, given that the survival of chicks is related to the number of vitamins in the diet of hens, and in laying hens a reduction in the laying of eggs is noted. In freshwater fish, is observed nervous disorders, skin hemorrhages, eye and fin disorders, gill necrosis, cataracts, photophobia, and high mortality rates” says Borges, reinforcing the idea that when hypovitaminosis is evident, diet formulation and vitamin supplementation must be readdressed.

ICC Brazil, a pioneer in the production of innovative solutions for animal nutrition based on sugarcane yeast additives, offers an alternative to the vitamin supplementation that is natural, safe, and GMO-free. StarYeast®, inactive dry yeast, is derived from the fermentation of molasses from sugar cane. As well as having high palatability, StarYeast® has an excellent nutritional profile, with a high concentration of complex B vitamins. B2 is one of the vitamins presents, which is necessary for the feed and nutritional demands of animals.
