Usage History and Application of Feed Enzyme Preparations
Usage History
In the 1960s, Enzyme preparations were first used as additives in compound feed in the United States. The first commercial use of Feed Enzyme preparations was in Finland in 1984, and its true application occurred within the past 30 years. The regions with the highest use of Feed Enzyme preparations worldwide are Europe, North America, and Australia. More than 70% of the sticky wheat feed for poultry worldwide contains Enzyme preparations; Due to the widespread use of barley in European compound feed, nearly 90% of poultry feed in Europe contain Enzyme preparations. The proportion of Enzyme preparations used in pig feed is much lower, around 10-20% globally. In 2005, global sales of Feed Enzyme preparations exceeded 2 billion US dollars.
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. The most widely promoted Enzyme preparations in China are phytase and non-starch polysaccharide Enzymes (NSP’s). In 2004, with the rise in the price of calcium hydrogen phosphate, phytase was increasingly used to reduce feed costs; Years of practice have proven that replacing calcium hydrogen phosphate with phytase is completely successful. The successful application of phytase has given feed companies more confidence in using Enzyme preparations.
Application
1. Eliminate Anti-Nutritional Factors in Feed
Non starch polysaccharides such as xylan, β - glucan, and cellulose are difficult for animals (especially monogastric animals) to digest and absorb. They are components of plant cell walls and can increase the viscosity of digestive tract chyme, leading to a decrease in nutrient digestibility and feeding effectiveness, limiting the application of grains in feed. Non starch polysaccharide Enzymes such as xylanase and β - glucanase can break down non starch polysaccharides and eliminate their anti-nutritional effects. Phytase can eliminate the anti-nutritional effects of phytic acid and improve the utilization rate of phosphorus.
2. Supplement the Deficiency of Endogenous Feed Enzymes
The phenomenon of insufficient Endogenous Feed Enzymes such as protease and amylase secreted by animals themselves is very evident in young animals and animals in sub-health states such as stress and disease: indigestion and a series of production performance declines caused by it, such as diarrhea in weaned piglets. Targeted addition of Exogenous Feed Enzymes will effectively solve the above phenomenon.
3. Reduce Environmental Pollution
Adding Feed Enzyme preparations can reduce livestock and poultry manure emissions. Feed Enzymes can improve the utilization rate of nitrogen and phosphorus in feed, reduce the nitrogen and phosphorus content in feces and urine, and most directly reduce the concentration of harmful gases in livestock houses, reduce the incidence rate of respiratory diseases of livestock and poultry and other diseases induced by adverse environment. It is Feed Enzyme substances that are added to feed to improve the digestion, utilization, or metabolic efficiency of animals.
