Feed enzyme preparations are additives that have the functions of activating endogenous enzyme secretion, improving nutrient digestion and absorption rate, effectively increasing the feed utilization rate.

Adding enzyme preparations to feed is an efficient feed management strategy that significantly improves food digestion rate, enhance animals' ability to absorb nutrients, and can also reduce the cost of feed.

​Adding enzyme preparations to feed is an efficient feed management strategy that significantly improves animal nutrient absorption, enhances immunity, and optimizes economic benefits.

The industrial use of Feed Enzyme preparations in China began in the late 1980s and early 1990s, with a rapid development rate in the past decade. Up till then, feed enzyme additives were already researched and used for around 20 years. It was first discovered being used in the United States before being used commercially in Finland, and ultimately making it to the markets big in Europe. Relatively speaking, it is a fairly new product with numerous beneficial elements that many companies in the animal husbandry industry are adopting today.

Feed enzyme preparation is a type of feed additive that can improve the digestion, utilization, or metabolic efficiency of animals by adding enzyme substances to feed. It is a common feed additive used in the animal husbandry industry for various beneficial purposes.

This standard specifies the terms and definitions, product classifications, requirements, testing methods, inspection regulations, as well as icons, packaging, transportation, and storage of Protease preparations.

Enzyme preparation mixed with feed or fed directly to pigs can greatly improve the conversion, digestion and utilization of nutrients in the feed, significantly reduce or eliminate the side effects of toxic substances and anti-nutrient substances in the feed, and has high economic and environmental benefits.
