Application of sodium humate
The application progress and application quantity of sodium humate in the breeding industry is not commensurate with the development of animal husbandry.
The reason is that the research and development of feed and veterinary drug management system and sodium humate are out of touch, resulting in a lack of work in this area, research and development are at a standstill; second, the problem of the application of sodium humate itself has not been seriously summarized and deepened. In the discussion, a few factors that are caused by a mixture of ingredients, rough process, and imperfect testing are unstable or safety hazards, which is a major factor hindering the passage of sodium humate across feed additives and drug approval thresholds and affecting further promotion and application.
Today, as the green wave is booming, sodium humate preparations, which are green feed additives, are once again popular. Relevant experts pointed out that only when affirming the results, not avoiding and actively solving the existing problems, can the application work continue to advance, they suggest: 1) focus on the selection of raw materials and the application of basic research. The bioactivity and medicinal effects of sodium humate from different sources are quite different. Even if it is also lignite, the samples of different ore points are not the same. First, we should choose to evaluate one or two high-activity samples of sodium humate in the country, from the laboratory to the farm, from pharmacology to clinical, in-depth and meticulous research in physiology, pharmacology, pathology, toxicology, etc. The link between the composition of sodium humate and biological activity or pharmacological action.
2) Improve sample purity and control impurity components. Regardless of whether it is a feed additive or a drug, the purity of the sodium humate sample should be as high as possible and strictly regulated. The free base in the sodium humate used as a medicament has an effect on the metabolism of the organism, and should be reduced as much as possible, that is, it is preferable to control the pH of the sodium humate product to 8.5±2.
3) The dosage of sodium humate should be adjusted according to animal species, variety, body weight, nutritional status, geographical environment, type of sodium humate, etc., and should be gradual. For example, the amount of sodium humate added to chicken feed is generally 0.02~0.03%
in China, and as much as 4~8% in Japan, The reason is many, it is not good to comment, but important The principle is that the amount of feed must be determined by experiment and cannot be copied. For example, when UHA is used for feeding, firstly, when the protein content in the original diet is 8-12%, UHA is added, and the amount of protein added is 16-18% based on the protein content (theoretical value). The original feed protein is not in this range, or the UHA is too high or too low, and the effect is not satisfactory .
4) As with crops, the increase in the stimulating activity of animal feed humic acid should be combined with the appropriate increase in nutrients to achieve synergistic effects. As Kruglov said, it is a true growth stimulator of sodium humate, which is most effective only when the animal is given enough high protein rations. Another example is that S and Co are important elements for the synthesis of amino acids from rumen bacteria in ruminants. Only proper supplementation of S and Co is more conducive to the absorption, transformation and utilization of sodium humate.
