There is room for the development of feed enzyme preparation

Introduction: on August 18, at the national "Application of biotechnology in feed industry" conference held in Zhuhai, Guangdong Province, experts analyzed the current production, sales and application prospects of feed enzyme preparations in China Liu Yali, director of R & D center of Zhuhai Special Economic Zone Yiduoli Co., Ltd., made a special report on "research and application of green feed additives" He believed that the application of green biotechnology products such as "enzyme preparation" and the gradual replacement of commonly used drug additives were effective ways to solve the problems of prevention of livestock and poultry diseases and improvement of production performance in animal husbandry He said that feed enzyme preparations have been studied and applied in China for nearly ten years, and more and more feed and breeding operators have adopted such additives There are five aspects of common enzyme use: 1) enzyme use in the development of high-grade feed (such as high-grade piglet feed, high-grade chicken feed, etc.) 2) In the preparation of unconventional medium and large pig feed, unconventional poultry feed, layer feed and duck feed, enzymes were used to solve the problem of anti nutritional factors 3) Enzymes are used to solve nutritional thinning 4) Enzymes are used to reduce the coefficient of variation of feed quality 5) Enzymes are used to reduce environmental pollution in livestock, poultry houses and water bodies In all cases, the most common is the use of such additives to improve feed quality and reduce formula costs The use of enzyme can improve the utilization rate of energy and protein, reduce the cost of formula, so it is a kind of food saving additive Grain saving feed additive is one of the biggest characteristics of enzyme preparation which is different from other feed additives Professor Feng Dingyuan, Dean of the school of animal science and technology of South China Agricultural University, et al Studied the effect of feed enzyme preparation added in feed In 1998, they used a kind of enzyme preparation containing xylanase and β - glucanase and other enzymes Pigs of 32.6kg body weight were used as experimental animals The diets were designed according to corn, soybean meal and bran types The digestibility of crude fiber, crude protein and dry matter were increased by 48.9%, 16.5% and 11.3%, respectively The results showed that the digestibility of dry matter, crude fiber, crude protein and protein could be increased by 9% - 20%, 36% - 49%, 11% - 18% and 6% respectively In other words, the production of the same livestock and poultry products can reduce the input of feed, showing the greatest characteristics of feed enzyme preparation It is understood that at present, the market of feed enzyme preparation in China has initially formed and is gradually developing There are nearly 10 foreign companies selling feed enzyme preparations in China According to incomplete statistics, there are more than one hundred feed enzyme preparation enterprises in China Their products include: Yiduo enzyme series products of Guangdong Zhuhai Special Economic Zone Yiduoli Co., Ltd., Huafen enzyme series products of Guangdong Zhaoqing Huafen feed enzyme Co., Ltd., yingheng enzyme series products of Guangdong Jiangmen yingheng biological feed Co., Ltd., etc "Natural, green, pollution-free and residue free" is the theme of the development of animal husbandry in the 21st century With the application of modern high-tech bioengineering technology, Yiduoli company has been committed to the development of green feed additives for ten years In order to develop grain saving feed, the company has developed and produced the first generation feed enzyme preparation in China At present, the company has developed into the largest feed enzyme preparation production base in China According to the statistics in 2000, the annual output of compound feed in China has reached 65 million tons If all enzymes are added, and the added amount is calculated as 1 ‰, 65000 tons of enzyme preparation will be needed If 30% of the country's compound feed is added with enzyme, 19500 tons of enzyme preparation is also needed In 2000, if the annual output of feed enzyme preparation is 5000 tons, 5000 tons only accounts for about 25% of 19500 tons Therefore, feed enzyme preparation has great market space and application potential in China.
