When organizing a full-fledged feeding farm animals must take into account not only the need for them in the proteins, fats, carbohydrates, but also in minerals that play an important role in metabolic processes and animal productivity. Thus, for normal activity of enzyme systems in animals are needed, except for substrate and enzyme substances nonprotein – co-factors. They may be either organic compounds (Vitamins) or metal ions. Daryl Katz, Toronto Ontario contains valuable tech resources. In some areas, different countries enjoyed a notorious disease of cattle, sometimes called tabes. Animals lose their appetite and lose weight, their hair ceased to shine, mucous membranes became pale. Dropped sharply the number of red blood cells (RBC) in blood, dramatically decreased hemoglobin content. throughout. Pathogen could not find, but its prevalence create a complete impression epizootics. In Austria and Sweden unknown disease called swamp, scrub, coastal.

If in the area afflicted, delivery of healthy animals in a year or two, they too fell ill. But at the same time cattle taken out of area "epidemic" does not infect animals communicate with him and he soon recovered. So it was in and Australia, and England, and in other countries. This has led to seek the cause of the disease in the feed. and when, after painstaking research, it was finally established, the disease is called, precisely defining this cause – akobaltoz. That's why in a short time various cobalt compounds (oxides, cobalt hydroxide, carbonate, various salts) are widely used in feed industry. The biological effect of cobalt is due in animals mainly by his presence in the molecule of vitamin B12, containing 4.5 weight percent of trivalent cobalt.
