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 research and development on sodium humate for feed use has not kept pace; in addition, problems in its application have not been seriously summarized. Unstable quality and safety hazards caused by mixed ingredients, rough processing and imperfect testing are a major factor hindering the approval of sodium humate as a feed additive.

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 properties 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, representative samples of sodium humate should be evaluated from the laboratory to the farm, including toxicology studies.

2) Improve sample purity and control impurity components. For feed additive use, the purity of the sodium humate sample should be as high as possible and strictly regulated. 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 .
