Feed is an indispensable and important part of the farming industry, and its quality has a profound impact on the growth and development and health of animals. In recent years, the continuous progress of science and technology has brought new development opportunities for the feed industry, and feed grade silica, as an important additive, has played a positive impact on improving feed quality. In order to guarantee the improvement of feed quality and the ecological and high-quality development of the breeding industry, it is imperative to formulate scientific and reasonable standards for feed grade silica.
Feed grade silica is a kind of high-purity carbon black substances, with nanoscale carbon black particles as the main component, and after special processing. Its characteristics mainly include high specific surface area, low thermogravimetric loss, good dispersibility, excellent adsorption capacity, and harmless and non-toxic. These characteristics make feed grade silica an ideal feed additive.
Second, the function and application of feed grade silica
The necessity of formulating the standard of feed grade silica
1. Ensure animal health and safety: feed is directly related to the health and safety of animals, the development of feed grade silica standards can standardize the quality of feed additives to reduce potential risks.
2. Promote the development of farming industry: the rational use of feed additives can improve the feeding efficiency and economic benefits, and the formulation of standards can guide and promote the scientific development of the farming industry.
3. Protect the environment and health: the development of the feeding industry can not be ignored on the impact of the environment, the development of standards to help control the environmental pollution of feed additives to protect the natural ecology.
